Rust Remover Showdown. Will Evapo-Rust prevail?
Вставка
- Опубліковано 15 лип 2018
- Several tests in this video demonstrate the strengths and weaknesses of various store brand rust removal products (CLR, Krud Kutter, Evap-Rust, Loctite Naval Jelly), Muriatic Acid, as well as other options such as using vinegar or Coca Cola. More product details at the very bottom of the description. Which one works the best? After conducting the tests, I like Krud Cutter the best. However, other products, such as Evapo-Rust proved to be very effective as well. Loctite Naval Jelly would be my pick for a flat metal surface.

@@ProjectFarm No problem. It gets boring down here and we all need something to pass the time.
Do you know who makes the best 1000 watt power inverter? I usually need it to plug in a 110v 5 amp water hose sump pump and have found myself near no power and have to drive on average about 20miles back to town to grab a generator. Tractor supply co, DeWalt, Duracell all make one but which one can deliver power without putting to much of a strain on my truck and run without over heating after 10minutes of use. I've looked on UA-cam and through forums but all they give is specs of them and not a actual test. If you do happen to do a video on this could you run such a pump on a 50ft extension cord? I know it's a expensive task to ask but if you find yourself needing a project idea I give you my deepest gratitude. Thanks and look forward to a "let's find out" video on 1000watt inverters
I've seen comments about ACF-50 (and the heavier version, Corrosion Block) mentioning that they can also remove rust. I would be interested in that being put to the test, maybe up against other rust prevention products like XCP Rust Blocker. Of course their primary purpose is to prevent rust but seeing how they affect existing rust would also be useful.
The Coke has a great use when removing rust. Mix it with some rum and drink it while waiting for one of the better cleaners to finish 😄. Awesome videos 👍.
Thank you!
davemc187 lol great idea
Haha!! That's a great use for Coke
true it also works on removing battery corrosion.
Project Farm Coke actually works really good when using some tin foil. If you brush a piece of tin foil against the metal with some Coke poured onto it the rust removes in seconds. Talking out of experience.
This has amazing high school science project energy, and I mean that in the most complimentary possible way.
Thanks so much!
Honestly this is so true. Break down why and how the product removes rust. Best in groups
This guy is the the most concise tester on the net. Hands down. That's some accolade for the amount of people who use it.
Thanks!
I use Evaporust all the time, but the thing to bare in mind with it is that it's a chemical reaction that is VERY temperature dependent. At normal room temperature it's quite slow, and almost ineffective at below 60° However if you put parts in a pot and heat them up to 100° - 120° it works VERY quickly, like Muriatic Acid quick.
Thanks for the feedback.
Very interesting, thanks
Thanks
Be careful with evapo-rust it will etch a part at the waterline. Make certain to immerse parts completely in evaporust!
Oh, obviously you're doing a commercial for the Krud Cutter. In addition to being the most expensive product, you had to soak the crescent wrench for 23 hours to get all the rust off, and in that time, although you didn't mention it, it removed the good metal too.
Muriatic acid would have done the same job in 30 minutes instead of 23 hours, but you weren't bought by them.
Please, never stop making these videos. I can't tell you how nice it is to have so much empirical data on commercial products. I like your methodical approach to testing and presentation of data.
Thank you very much! The positive feedback helps!
The problem is, there are only so many things to test. Will be sad when PF reaches the end!
I thought you said he should stop lol
It's only one test per product lol
This is one of the best channels on UA-cam. Your tests are so incredibly useful in daily life when purchasing products. Nobody else does testing like this. Thanks so much.
Thank you!
@@ProjectFarm Me too
Project Farm you didn’t lie, you do read everything! Props to you (claps in sign language)
I know I'm probably late on this, I use evapo-rust when restoring car parts, mainly because it does work fantastically and is very gentle at the same time. Also the evapo-rust you can use over and over again. I usually will strain it to get any large particles out and then keep using it. I also usually let parts soak for 3ish days. Also evapo-rust has no harsh acids so if you spill some it's not a huge deal.
Thanks for sharing.
Thanks
Have you ever tried to using it in a car radiator coolant system and keeping it inside for few days ?
@alberta3157 it won't do any good for that, radiator coolant has rust inhibitors already. If you have trash in your cooling system go get a professional cooling system flush. Will do a much much better job.
@@themeez1000 it costs around 150$, they are not telling you if they are using any solution, they just connect a system that presurizes the cooling system and using heated water/solution to circulate for some time.
So I'm not sure about that ...
Given the fact that it's less than half the price of Krud Kutter, works almost as well, can be used over and over (until it's black, which takes a long time), won't hurt you if you touch it and can be disposed of by just dumping it out or putting it down the drain, I think Evapo-rust is going to be my choice for the projects I have coming up. This is an excellent video - thank you!
Thanks so much! Thanks for sharing.

@@markspc1 You're a goon....this dude is easily the most non-biased tester of products I've ever seen. Some boneheads gotta hate on everything. You do you I guess.
Krud Kutter is basically phosphoric acid (the safety sheet says
Can this be put in a bottle & sprayed on rusty frame sections on a truck or car?
Hardware store employees need to start watching your videos instead of recommending products without any actual knowledge of how well they perform..
Thank you!
lol do your own research bro
Reel-Lentless not true although they are harder to find.
I always loved going into Best Buy, Circuit City, and a few other choice electronic stores to have employees start reading off the side of the products that they were trying to sell.. Let's see; I believe I can do that myself.
In any number of stores, what gets recommended is often a function not necessarily price, but how much profit is made; the staff is taught which brands give them the most profit; in other stores, some employees figure that the more expensive product is the product to sell ( most profit ) .
@@MrPir84free I don't have a problem with them reading off the box, as long as they can explain what the features listed are and mean. Or can explain the differences between products. So it's not just: "well, one box says it has a 2-ohm resistance speaker and the other says it has 4-ohm". Ummm.... Ok....what's an ohm and what do the different numbers mean? .... If they can explain things on that level....I'm good.
Great experiments. Arguably this is more practical advice than, say, whether or not I can run my lawn mower on WD-40 but I do appreciate the bizarre tests too.
lol! Yes, this is much more practical but I enjoy the crazy videos too. More of those coming soon.
Yeah, those other tests are nuts! Pun intended.
But they are soo much fun!
Not completely... Most of the products tested are not known in Europe. But everyone knows the stuff he puts in an engine. What's the point of testing if products are not available (or at insane high prices).
I'm always a bit dissapointed when it's not an engine test because of this.
Project Farm can you try baby oil as engine oil?
Why not try used deep fried fast food oil in the crankcase? Lol
We’ve used Evapo-rust at work and I’ve been SUPER impressed with it. They do warn that it does draw some carbon to the surface, but I doubt it’s an amount that would change the strength of the material. It takes time, but holy crap, it does work.
“Started to eat some of the metal”. That’s not good. Evapo-rust doesn’t do that. Something to consider.
One thing we were able to do with it was remove some rusted and seized 1-1/4” studs from a massive valve body. It will creep in like a penetrating oil, and it actually seemed to be more effective.
Great information! Thank you
I second useing it to free rusted up things. Works 1000x better than wd-40. Not to mention you can put metal parts with plastic paint and anything in between and not have to worry about the evap-rust hurting anything other than rust. Short of needing something rust free same day evapo-rust is king. Super reusable and affordable too
So does the Evapo-rust start eating the metal if you leave it in there for a long time? How long should i let it sit for? I wanna use the evapo-rust on a chrome bmx frame.. will the evapo-rust eat up the chrome or turn it a different color? There’s only a few spots on the frame that’s rusted but the chrome is still nice and would like to keep it ... any info would be appreciated, thanks
@@ladron775 I've not used it on Chrome before but I've used it on stuff with paint and plastic as well as aluminum and brass, I'd advise using it on a small patch of chrome to ensure no discoloration but I doubt you'll have issues. It will not eat away at metal, I've forgot stuff in it for a week one with no metal being eaten. It takes about 24hr to work depending on how heavy the rust is ect, a scotch Brite pad to knock off anything loose is helpful too if you're in a hurry
@@ladron775 not sure about chrome, but it does change the surface colour of the raw steel. Somehow it draws a very small about of carbon to the surface, darkening it. Given that Chrome doesn’t contain carbon, you’re probably fine, but test a small spot to be safe.
No, evaporust doesn’t harm the metal at all, or paint or other coatings. It’s also extremely safe to handle. Their MSDS listings on their site will confirm that.
Thanks for the uploads over the years. I would say that I've learned something useful from every single one. Putting this type of program on youtube is pure genius as I believe almost everyone can learn from these uploads.
FINALLY!! A UA-cam video showing a well-designed comparative study with controls!! Thank you for this!!!! Your experiment has been extremely helpful to me!!! Yay!! Great work!!!!
I absolutely love these videos. You do a great job of comparing products in a controlled, measured setting--without hyping any sponsored products. It's always a gamble when you buy and try a product. You are doing us a great service by really testing these products well. Thank you.,
Thanks for another great video ! An old guy once told me he used WHEY to loosen rusted manifold bolts on a marine engine. He said you could then turn the bolts out with your fingers. He chose to use whey because they used to feed their pigs on whey from the local cheese factory, and the iron feeding pots never got rusty. I've had good results using whey on rusty tools, bolts steel wire and chain. Sometimes I left the rusty item immersed for a week or more. Can be a bit stinky in the hot sun, but put a lid on the plastic pail. When done, wash the item off with soapy water, dry it, then apply a coating to prevent rusting again. As a quick fix, I threw several lengths of chain in pails of used engine oil over the winter. I may wipe off most oil, leaving enough so I can store chain in damp conditions. Or I may clean up and spray cold galvanize or some other pail coating. Whey is cost effective for big jobs if, as I did, you get pails of whey for free from a cheese factory. [ RIP Uncle Billy ]
You are welcome! Thanks for sharing.
This was fascinating
You make amazing quantitative, real-world comparisons. Excellent! They are also clear and well-produced. I'm a fan.
Thanks!
Coca cola & whiskey is best, after a couple of glasses it makes everything look fantastic....relationship, job, bank account, even rust!
We're gonna test that!
This is the second video of yours that I've watched and I'm extremely impressed by your presentation. You do a very good job of explaining the products, giving them a good amount of time to work, and using the control to do a comparison. Very methodical and easy to follow. Thanks for work and for sharing your results!
Wow, thank you!
Todd, Dude, you are rockin' these product testing videos!! I only just now realized how many of your videos I have watched. I've begun to look for them if I'm wondering which product to buy for my repairs and maintenance activities. I enjoy the style you have adopted for your testing - the straight-forward, get-right-to-it approach is much appreciated. Keep up the good work!
Thank you, will do!
Sometimes you definitely get what you pay for. The Krud Cutter did an amazing job. It’s definitely worth the extra money 💴 in my opinion. I would buy it... and I’m pretty frugal lol 😆. My favorite videos are when the less expensive products/items beat out things that cost 5-10X as much. But hey, we all occasionally have to pay. That’s the difference.. knowing when to save and when to spend. I love the reviews and comparisons. God bless and keep them coming.
Unless you need it done as fast as possible then the Evapo-Rust is the better choice due to how safe it is all around, especially regarding disposal.
Muratic acid?
I clean everything with Krud Kutter.
I just applied Krud Kutter to my mower deck, turned the rust spots white. I plan to use Fluid Film as the top coat. It will be interesting to see how this will work when I hit the wet patches of grass. Normally I DO NOT mow wet grass, but this year (West Central Wisconsin), it has been raining EVERY OTHER day, so I have no choice! Lawn maintenance SUX!!!
I'm fairly sure most of these biodegradable rust removers contain the exact same active ingredient, but the concentrations might be different.
Hand Tool Rescue wonder what concentration is in coca cola ;)
Hand Tool Rescue, Great point! You've got a great channel and lots of comments about the great work you do. Thanks for checking out the video!
Hand Tool Rescue - Wondering if its safe to use Krud Kutter or Evapo Rust with an Ultrasonic Cleaner on Brake Calipers (Don't want to cause an explosion, fire, or damage rubber components of the Brake Calipers) ???
GONEWILDFILMS, Should be no problems with Evaporust in ultrasonic cleaner as far as reactions. It's inert. It usually won't harm anything like paint, and labels, so your rubber should be OK. Just de-rusted a pair of handlebars for a push mower, that had a 36 year old label on them with instructions on how to start the mower. Didn't harm the label at all. You want to make sure what ever you are using evaporust to remove rust with is clean. Grease, dirt, oil, brake dust will contaminate it. I don't know if an ultrasonic cleaner doing its ultrasonic thing will make it work faster, but if your ultrasonic cleaner has a heater, that will make the evaporust work faster.
50 years ago, my Grand-pa taught me to use Molasses as a rust remover. The same stuff you buy in the grocery store. I use a 50/50 mix of molasses and water. It does take alot longer to remove the rust than what these test times were, but it is a cheap and non-toxic way to remove rust.
I love this channel. Just found it recently. Your approach to testing is exactly what I was looking for. You have data backing it all up. **You clearly display all the numeric data ** which I find a lot of other not doing. In addition you provide price to performance comparison. THANK YOU for being what I consider to be a gold standard and why You Tube was created.
Awesome, thank you!
Such a thorouh walk through in this video. Im in awe. Thank you for this review!!👏🏾👏🏾👏🏾👌🏾
You are so welcome!
Your timing is awesome. It never fails that one of your tests pop up when I am getting ready to tackle a project related to your video.
This time, it's a 2007 HD Dyna Low Rider fuel tank on a bike that has been sitting for over 6 years with fuel in it. Nice nasty layer of rust in the bottom of it that I need to remove and treat prior to resealing the tank.
I got a kick when he had to tie strings around his nuts just to dip them in coke
sounds like a crazy night
LOVE the clarity & presentation. Got my answers, so thanks for doing the hard work! You are awesome man!
Thank you
I tried a few of these products on my own... the only thing the Coke did was make my old, rusty tools WET. 🤣 Rust Kutter says it is a "Rust Converter".
Any idea what the heck THAT means?
I REALLY enjoy your videos!
Just discovered your channel. I love your comparisons an the detail in which you do your tests. Great job…I am now subscribed.
Welcome! Thanks for watching and subscribing.
After having accidentally mixed clr and vinegar one time, and having to evacuate my home because of the toxic gas from the chemical reaction watching you have those two products so close together during this testing had my anxiety through roof.
Thanks for the feedback.
yikes haha
Are you sure this wasn't two different products. I'm studying to be a chemist but j know that clr is a mix of lactic acid and a surfactant and that should have no issues being mixed with viniger whitch is just a 5% acitic acid mix
@@putinslittlehacker4793 it was Drano not CLR
@@ProjectFarm I apologize for my earlier comment it was not CLR.
You can't imagine how valuable your videos are. Speaking for myself (and i'm sure every other subscriber), they have saved me so much time and $$. Thank you sir!
Thank you very much!
I like using evaporust for stuff that isn't time sensitive. You can leave it, forget it for a month and when you come back it's got the black coating over it (you don't have to leave anything for more than 48hrs though). I love using electrolysis for removing rust on larger objects. Last summer I did this to my seat rail because it was frozen in the all the way back position. It was able to treat the whole thing in about 12 hours, and I was able to put it back in the car by the next morning.
Another tremendous video, I love watching anything you produce. I was wandering, did you do a follow up video on the spanner you left out in the elements?
Great video and testing setups Todd!
The Muriatic Acid works better than anything I've ever found for removing rust and scale. The key to not losing much metal is short immersion times and neutralizing the acid right after removing the item from soaking with a baking soda and water mixture. I've worked with Muriatic Acid many times over the years and I don't think it is as dangerous as most people seem to think it is. I have never been burned by it even when it has gotten on bare skin, however, you DO NOT want to inhale any of the vapors or get it into your eyes. It will burn mucous membranes rather quickly.
The craziest thing I have ever seen with respect to Muriatic Acid is watching a drunk grab a bottle of it and take a big drink, thinking it was beer. Needless to say, he spat it out quickly and was dosed with a baking soda and water mixture to neutralize any remaining acid. He never exhibited any adverse symptoms from his "big gulp" and carried on his drinking afterward...some people...
How about a video showing people how to "sharpen" old metal files using Muriatic Acid and Vinegar? I've tried it and they both work, but the acid works much quicker. The acid works within 10-20 minutes and the Vinegar takes several days. It does extend the life of your files a good bit too. I didn't believe it until I tried it for myself, collect some old files and give it a try. Just be sure to clean and degrease the files first. Thanks for the video!
Thank you very much for the terrific video idea! Also, thanks for the information on muriatic acid. I learn a lot from the comments. Finally, what a scary situation regarding the "big gulp" of this stuff! Thanks again.
Oxalic acid. Cheap, better, and you can leave the part for weeks.
Evapo-rust definitely doesn't work the fastest but anybody who watches handtoolrescue knows that it works pretty darn good. The plus side for evapo-rust is that it isn't super toxic like the rest.
Great point.
It's non toxic....the muriatic acid....is bad stuff....i restored wrenches that were nothing more than a ball of rust with evaporust.....
Nicholas Korner Just don't drink it...
Nicholas Korner your stomach already makes hydrochloric acid. Its not that bad. Just don't let it sit on your skin too long and protect your eyes.
Your stomach only contains
Excellent test/review. I appreciate the cost per ounce addition. One thing that I like about Evapo-Rust is the ability to reuse it. Muti-use lowers its net cost.
Thank you! Thanks for the feedback.
I’ve had great luck with evaporust. I just soak overnight and it gets all of the rust. And no they didn’t pay me.
Excellent video, thank you! One of the few times I totally believe the presentation and have no apprehensions about the accuracy of the results. I am following your channel.
You are one of my favorite contributors on UA-cam. The amount of time you spend on your tests is apparent. Thanks for taking one for the team, over and over again
Thank you very much!!
That coke bottle was so embarrassed it tried to sneak off at the end of the video.
lol!
And yet on the taste test, Coke won - go figure!
wow, the videos from 4 years ago are still as quality as 4 years later, keep iup the good quality!
Thanks, will do!
Another eye opening and informative comparison. Thank you so much for testing these chemicals to determine which product does in fact remove rust better than another.
You are welcome!
Great way you test and baseline these products. Love your vids!
I've always thought of CLR more as a cleaner for hard water stains on bathtubs and things like that. Like the videos. Thanks for making them. :)
Thank you!
Me too, if you look on the bottle it says something about removing rust from porcelain and brick. I think it's made to remove rust stains.
Dsdcain I have used CLR to remove hard water stains. I should say “tried” to use. It did nothing at all.
I agree. I typically use it for hard water stains as well and haven't tried with rust yet
However, I can see the justification for testing it since the name implies it should:
Calcium, Lime, Rust remover
Clr has always corroded anything I have used it on
Great test!! Thank you all the time and effort you put into these videos!
You are welcome! Thanks for watching!
I am kinda addicted to these videos, keep them coming, they are full of relevant info.
Thanks, will do!
You have one of the greatest channels ever. Actual results.
Thank you very much!
This is the second video I had watched of yours, and I just have to say you are awesome. You defiantly put a lot more thought behind your testing than the average person. With my science degrees (mostly in biology and apply Anatomy and Physiology which much applys also some understanding of chemistry and physics)I had learned to do that every thing as well. I will even go as far to say that you put more though than most scientific journals I read to get more honist results and interpretations of your results.
Thank you!
I haven’t watched him for a while, but the fact this guy isn’t sponsored at all is pretty cool. (It may have changed. I’m at the beginning of the video.)
Imagine when he started the channel, was making zero money, and just experimenting with stuff with his own money with no return.
Good for this guy! Liked and subscribed.
I love this guy, BUT I wish he would slow down the "speed reading" from the "Q-cards"! Don't know how he can talk SOOO fast without catching a breath, but it is annoying at times! LOL
Thanks that was definitely entertaining. I have many rust removal tasks; the information you have provided will be of great use!
Hey there, love your testing videos. Very useful for craftsmen. I especially enjoyed your epoxy comparisons. Thanks for doing all of these!
Glad to hear! You are welcome!
I’m preparing for de rusting under my car before spraying fluid film, this was so helpful, the thorough method of testing products is appreciated.
Thank you!
Why in the world would you do that? Fluid Film will destroy any rust by itself
@@barackobama5304 Even according to fluid films website it is formulated to stop the spread of rust it does not remove rust.
Lol, I have gone to your videos before I buy tools and you always have one for what I want. Starting looking for a rust removal. Didn't even think you would have a review for this!! You're amazing! Thanks for all you do!
You are welcome!
A Jaguar mechanic friend of mine uses Naval Jelly to clean wire wheels (notoriously difficult to clean without total disassembly). The performance was very impressive.
Just as always, you've already made a video of something I'm looking for. Rock on!
Glad to hear! Thanks for watching.
Can't stop watching these! So good!
Thank you very much!
A great video, thanks for posting. I tested a couple of rust removers along with white vinegar a couple of years ago to treat the rusted interior of my motorbike petrol tank . Out of all of them I found Evaporust was the best, followed by white vinegar. I left the tests overnight. I still have the container of Evaporust in my cupboard and I'm still using it. I recently used it on a pair of pliers I found buried in the garden and they came up pretty much like new!
You are welcome! Thanks for sharing.

Awesome information. Thank you very much. You have just saved my motorhome! It would have cost me over £4000.00 to sort out the rust. But now I can do the job myself for only £250.00 and probably a second hand door. Brilliant video!
Thanks! Glad to hear!
This channel is the best!!! Every time I have a question he's done a video on it.
Thanks!
Here I thought evaporust was expensive! I like that evaporust can be used over and over again and non-toxic so if it spills I don't have to worry about it.
Thank you
Evapo-rust is my go to for over night use as it's safe and I live near a water way and want no toxic chemicals to leach.
Kimo Kalihi I also use Evaporust & love it. I mostly use it to dip rusty parts in the 5 Gallon bucket that I bought from Amazon, $75 yeah that's expensive but worth it. I pour it inside the engine block to remove all the passages where the water coolant flows through while closing off any exit areas like where the water pump attaches to. 5 days cleans it very nice to the bare iron cast. I also dip rusted parts in the 5 gallon bucket. If parts don't fit, then I use a sprayable gel called Krust Kutter. Don't forget to acid etch all rust treated metals, otherwise the rust will eventually come back in less than a year.
I actually conducted this test, by accident, on a crescent wrench. I found a rusty wrench in a yard I was cutting. All I used was a wire brush with Wd-40 and 3 in 1 oil. That was almost 3 years ago and I am still using the wrench with no issues. Love these videos!
Thanks so much!
Wow 😮
I always appreciate Project Farm's testing. Appreciate your time. I recently had a use for a product like this. I went with a 5 gal. bucket of Evaporust. I let stuff soak for 24 hours before even looking at it. The stuff did great. I followed directions, pulled it out of the bucket and wire brushed it all and resoaked it for 24 hours to get to the deep pitted rust. Rinsed off and ready for paint with ALL rust removed. I believe the key is total immersion and at least 24 hours. And Evaporust can be reused until it eats 1 lb. of rust per gallon.
Thanks! Thanks for the feedback.
Love this channel watch it many times to make a final decision on some products.
A little vibration with all of your testing and you would have had different results.
I've used all of the products over the years. Vinegar with vibration works wonders and it is super cheap and Way easier to nutrelize.
A couple of those will continue to break down the metal for months after used. Water doesn't stop the acid reaction.
Thanks man! Keep doing what you do! You have helped me and others alot.
Thanks, will do!
For small parts, nuts, bolts, etc. that will fit in my Harbor Freight ultrasonic cleaner, I use Evapo-Rust. The heat and agitation added by the ultrasonic cleaner really help get rust out of all the threads and small spaces. For parts too large to fit in there, I use electrolysis instead. Washing soda (or Oxi-Clean) dissolved in water is the active ingredient, and electric current supplied by a battery charger does the work. Another benefit is that what is left over is non-toxic and can be dumped in the yard. That assumes that only ordinary steel was used and not galvanized or stainless steel because they will create a toxic residue. I have used Naval Jelly in the past, but in more recent years I use one of the two methods I just described instead. If I do use Naval Jelly, I like to cover the jelly with plastic food wrap to keep it from drying out, because prolonged soaking seems to work best. I also ensure that I scrub the part down with an abrasive pad and water to remove the residue completely. Great video, BTW.
Agreed - With the Harbor Freight ultrasonic cleaner with heat it takes about 2 hours for me to remove rust on small parts with EvapoRust. With the bigger pieces I just put them in a tub and cover with Evaporust for a day or two. I may try the Muriatic Acid though next time i'm in a hurry though for the big parts.
Galvanized steel is just zinc-coated, so it should be non-toxic. It might even be beneficial, if your soil is zinc-deficient:

Great comment! Thank you for the extra details. Not sure just what I could use this for yet.. my boyfriend has a ton of rusty tools in the garage but he thinks it's weird that I want to clean them up & get them organized on a peg board. "That's like me asking if I can wash your makeup brushes for you..." Fair enough!

Try high temp RTV silicone as a head gasket material to test its durability against heat and pressure.
Great video idea!
Great ideas
Did this a couple of times on an MGB 18V engine. The RTV worked better than the high performance copper head gasket and was easy to clean up when I needed to work on something else (those things were known as tinker toys for a reason)
Maybe also do a gasket dressing comparison? such as copper spray, hylomar, hondabond, the right stuff, or others that you can find. Personally, I like hylomar and hondabond.
Wonderful, practical test. Rock on Project Farm at producing quality tests that have practical value. Thank you!
Thanks and you are welcome!
Great video! I needed something to get the rust out of a boat fuel tank and thought I would check Project Farm. You did not disappoint! Thanks again!
Thanks and you are welcome!
Another very helpful video, thanks for taking the time to do these practical, unbiased tests - resist the sponsors if they come knocking !
Glad it was helpful!
Hot damn Krud Cutter. Never even heard of it before, only Evapo-Rust with all their sponsored content.
Thank you
Krud-Kutter is just a phosphoric acid solution and has its place, however, it is an acid. Evapo-Rust will not affect good metal. Sure, other things work faster, but Evapo-Rust never claimed to work fast. In 24 hours, it works great and does not create microscopic pits like acids do. Even phosphoric. Phosphoric acids leave a phosphoric oxide coating that will fight surface rust for a while, but it still pits the metal like every other acid. For most things, it's probably great, but for times you really want the underlying metal untouched, Evapo-Rust is great.
also need to wash under the sink rub with a brush what helps it. i think why it wasnt the best is because it was so rusted out i think they say to use a wire brush to remove top layer. I still love my evapo tho
Microscopic pits are great when you want to coat the metal with a rustproofing paint.

I was wondering about how much the krud cutter would attack the other metal. Thanks.
Your test are amazing keep doing it!
Thanks, will do!
Hey I wanted to say thank you for making the video I’m 100% sure it helped out others like me appreciate the video
You are welcome!
Been here since 26k subs your channel growth is all proff of how awsome your content is
Thank you very much for the positive comment!
Im suprised how white vinegar did. I always soak my old rusty horseshoes in white vinegar overnight and next day everything brushes off easily.
Yes, these were very badly rusted nuts and bolts.
Did you brush it off, it works great
Vinegar works well, but it takes longer. The rust will wash off. It won’t etch the metal, either.
My comment exactly. Vinigar need a little wiping to get clean
Well yeah, many products will work with elbow grease, even the coke with enough friction (albeit it's effectiveness would be 95% elbow grease and 5% coke), these products are formulated to be stronger so they penetrate without needing as much elbow grease, vinegar is just a weaker acid at rust removal since it's so heavily diulted (most of these are using acids for removal); vinegar is just diluted acetic acid.
This could possibly be the best channel for making a good choice 👍
Thanks!
You are a heck of a scientist. Thank you.
You are welcome!
You are amazing bro, i look all over the net for which product it's good for clean the rust on car's frame.
Now i think i get what i looking for it.
You are super. I wish you all the best bro.
Thank you!
This is the most metal channel on UA-cam right now! #ForScience
Thank you!
Great honest video. I used Eastwood's Fast Etch on some very rusty brake rotors and was amazed at the results. The rotors looked new; I soaked them in a tub. The axles were left on the car but cleaned up nice by soaking a rag in FE and leaving it on the vertical surface.
Thanks for the feedback.
Thank you so much for your detailed experiment. I was able to clean my rusted golf club! Cheers!
Fantastic!
Love this channel. I would like you to test Rust-oleum Rust Reformer paint. I would like to know if it lives up to its claims.
I was trying to restore my recently deceased father's old stuff. And your video is really educational. You got a new subscriber. :D
Thanks for watching and subscribing!
May he rest peacefully
Another great test. I’m sold on Kris cutter. Thanks for sharing.
No problem!
Excellent video! Thanks again!
You are welcome!
A couple years on, how did the krud kutter work on preserving that metal?
And thanks so much for your honest reviews!
The rapture is soon, repent and Jesus loves you everyone
Super handy video. Thanks!!!
Thank you!
Man! I never knew there were so many options to remove rust! Thanks!
Thank you
People don't see the work and planning that goes into your videos, thanks for the content
You are welcome!
The active ingredient in the Krud Kutter and Naval Jelly is phosphoric acid. It might be interesting to try a product like a Klean Strip Phosphoric Prep and Etch, which has a higher concentration of phosphoric acid and costs a lot less (~$0.12/oz). Phosphoric acid is great as a rust remover because it reacts with the rust and makes it water soluble and does so at a rate much faster than it reacts with steel. When it does react with steel it forms an iron phosphate coating, which slows further etching from the acid and also slows future rust development.
Ideally, to restore a piece of rusted metal, you would leave it in the phosphoric acid long enough for the rust to be removed, but not long enough that the phosphoric acid starts reacting with the steel and forming the black phosphate coating.
Great point.
but black phosphate protects against rust, right?
In addition to my Scout 2 (They LOVE to rust) I have an extensive Medieval arms and tool collection. Vinegar works great and is the classic means for rust removal, plus it's cheap and leaves a natural metal bluing. It works slowly, however. I can't explain your nut results with it.... and BTW Amazon has gallons of Crud Cutter for 17 bucks and free shipping if you have Prime
Stefano Dogg. It's (Krud kutter) The Must For Rust. I also use it & love it. It's a water based product that says to clean the dissolved mushy rust with water, DON'T because flash rust will come right back. You will eventually have thicker rust build up after several weeks. I use either an acetone wet rag to clean it up or I spray acetone then wipe off with a dry cloth. Finally I neutralize the metal with an acid etcher, to prevent future rust, just before I primer it with either etching primer or epoxy primer.
Hey project, This is the best channel on youtube. Thank you Mr Farm
Thanks and you are welcome!
I have recently come across your videos and really enjoy them! Just wondering if you ever went back to that wrench that you left outside after it was cleaned by the krud?
Did you ever do an update on the wrench that sat outside?
I'm sure it's coming real soon now. Nothing else to do these days😜😮😨😢
Yes, ^^^ my question also.
^^^^

One year later
Great video! I've used muriatic acid in the past to restore automotive parts. Although it's extremely effective it also strips protective finishes from nearby metal. Using this stuff in my garage caused most metals in my garage to rust. It completely rusted out my drill press and a bicycle that had never seen a rainy day in its life. Just the evaporating gases caused this. Very nasty stuff.
I also left some bolts soaking in it for over a month and when I removed the bolts they crumbled in my hand.
Love the content!
Thanks. Thanks for sharing!
Thanks for sharing!
Thanks. I've been debating on getting some Evaporust mainly since it's reusable and this helps a lot.
You are welcome!
Hey Todd, I just have to say this is the 3rd time I have come back to this video since you made it 4 years ago! You have personally helped me. I purchased Naval Jelly for my vehicle and now I'm looking to restore a 1950 Delta Milwaukee 4'' and 6'' Jointers. So once again you save the day. Also I will be uploading those, so anyone interested stay tuned! And Todd. You're the fuckin best, man!
Thanks! Thanks for watching! Glad I could help!
Great comparison, thank you!
For those of us that do automotive work, it would be very interesting to see which rust remover/converter products are most friendly to plastic, rubber, and soft metals. Knowing what cam be used to take care of rust under a vehicle without having to pull everything apart would be very helpful!
Great suggestion! Thank you.
My thoughts exactly! Ty
Brake studs were a perfect choice for your test . The Kurd kut very impressive. If I remember correctly, the naval jelly was designed to create a barrier layer that is not to be removed. Kurd kutter hands down winner. But in a vertical application Naval jelly will be the winner. great work man!
Thanks!
This is a great comparison video, thank you
Thanks and you are welcome!
I love your videos. Very helpful for making decisions
Thanks! Glad to hear!
