Rust Removal - Is Stronger Vinegar Better than Regular Vinegar?
Вставка
- Опубліковано 3 жов 2024
- Why are there so many vinegar strengths to pick from at the store? Is one better than the other? Is it a gimmick to just sell more vinegar at higher prices? In this video you will see that all vinegar is effective at removing rust. Just because it is "stronger" vinegar, that doesn't mean it is better.
Nicely done! Just love these simple, easy, straight to the point video.
I use 45% in my home shop. The biggest difference that I see is with breaking down the scale on hot rolled steel. An hour or so in 45% softens it enough so that it grinds off easily. Whereas overnight it wipes or rinses off completely. With lower concentration, it takes several hours or overnight just to soften.
I'm currently restoring a 1971 snowblower and soak all the nuts and bolts in vinegar overnight then scrub them with sos pads and they usually come out looking new, sometimes they need to go back into the vinegar for another 12hrs then scrub them again. I use the least expensive vinegar I can find which is usually the 5%. I've used the 6% cleaning vinegar and it doesn't seem to work any faster, still soak overnight initially.
These comparisons are very useful and are appreciated. Thanks.
My pleasure Ken.
Thanks for the tip and great video! For small parts cut on my cnc plasma table, I now use 5% vinegar in my ultrasonic cleaner. It goes pretty quick actually
Thanks so much for the tips !! Areas I need to get tons of rusty items cleaned...such as old tin roof; pots and pans neglected far too many years outbuilding storage..Thanks !! This will save bundles!!
You may also be interested in another video I did on treating rust using a product called "ospho". You can search my channel for it. Thanks for watching.
I used 5% acidity vinegar every time due to cost as well but I use it to remove rust & clean. Bolts, nuts, washers I find on the street just to repair the threads with the sets I got, I leave them submerged for about a day to a day in a half.
After you're finished using the vinegar you need to rinse it with a solution of water and baking soda to neutralize the acid in the remaining vinegar.
What is the mix ratio for mixing it
@@douglasbattjes3991 I guess a one pound box of baking soda to 5 gallons of water should work.
True
@@douglasbattjes3991 No need to be a chemist, just rinse thoroughly with regular water
wouldn't the water make it rust again ?
Timed test should have been the same time with a look for differing end results.
Factors like fluid surface tension and penetration could be similar (say the first 15 minutes for example.)
This would leave 45 minutes for the low % and ~2 minutes for the higher % to work optimally after overcoming the above factors to saturate the rust.
wow~! Great to know. Curious to know how it works for hard water stains. Please do a video on this~!
I've read that many of the stronger vinegars are often petroleum- based. FYI... You may be able to find the 20% at some garden centres since it can be used as an organic weed killer.
Thanks for sharing your knowledge and expertise with us. Please make more vids. Kind regards from Scotland.
Thanks for watching. I release a new video every Sunday.
I bought 15 gallons of 9% vinegar from HEB grocery and diluted it down to 3% to restore a large mower deck that was left in a pasture for 5 years. I decided to go ahead and throw in some other rusty parts and got some on my hand... it was definitely still very acidic. I will update my results after 24 hours.
They're the same price if you work out price vs cost.
Buying 30% saves packaging and space so well worthwhile
You’d actually save a bit of money buying the 30% bottle and diluting it 6 times. The 30% bottle is twice as large, 128 fl oz, so one could make up to 768fl oz of 5% vinegar, from the $20 bottle vs spending $48 on 12 of the 5% 64fl oz bottles.
I'm not sure about that. He said the 30% jug was $20 PER GALLON
But even at that price it's still slightly more cost-effective at $3.33 a gallon when diluted versus the almost 4 dollars per gallon for 5%

My ex wife used my $21.00 30% Vinegar on her salad while i was at work. She didn't show up to divorce court something about her internal organs, esophagus. So i get to keep all my toys ,and my house.
30% vinegar is not to be used on foods. That's potentially corrosive and toxic.
I love this guy!
Very helpful - clear and concise.
Good comparison, I was just wondering! Thank you I won’t waste my money
Glad it was helpful.
Very good video. from London, UK
apply household ammonia solution after the vinegar treatment, it will prevent the quick rerusting by making the activated surface "inactive"
So many keep wondering and asking "does stronger work as well, " or I quote: "The big advantage of more concentrated vinegar would be," Well, 'Alley Picked' clearly stated using the higher percent did not outperform the cheap 5 percent. Really, he answered the question.
Anyway, I am only twelve hours in and have a totally unbelievable result.
A friend had an old barn, she was to tear down to rebuild. It was locked with no entry for about a year. As they cleaned what was inside making ready a demolition, an old family Walther PP was found in a dank corner under a puddle of wet rags saturated with dog urine. .(don't ask, I didn't, she was already embarrassed). I went to her place to check and found the pistol was frozen with rust.
Not knowing what to do, I made a reasonable guess, i immediately placed it in a tub of olive oil. It was all she had available. At first, I could not move the slide. The slide release was ok, but the slide did not move . Then with great effort still saturated with olive oil, it moved a quarter of an inch, then I was able to move it.. The clip looked rusted into the frame and did not move period. Using a flat pry tool, I could not break the clip free. So, I got online and found this video. That was about 12 hours ago.
I wiped off excess oil, then put it in a 5 percent white distilled vinegar bath and left it until now... OMG, the rust was separated from the base metal. I've never seen that. It seemed to be a miracle, the pistol can cycle now, and I am certain it can and will be restored. )My girl is so embarrassed.
Thank you.
use used auto trans oil. it good lube
the vingar will keep eating metal. u gotta clean all of it off. baking soda?
So if 5% is vinegar and 95% is water, could you not add water to the 30% vinegar and make 6 gallons, which would make it the cheapest and still 5% vinegar?
Yes you can. It would be the same. At least if the water is relatively clean. Very hard water might slightly impact (counteract) the acidity level, but it would have to be pretty severe hard water to make an appreciable difference.
It's also just a lot easier to store concentrate until you need it, so always buy the more concentrated version IMO as long as you aren't paying a lot more pr. percent.
I buy vinegar in 32% at a building supply store - it's intended to be used to clean mineral deposits of stonework.
I only became aware of 30% vinegar recently. I wanted to use it to de-rust a motorcycle gas tank. I mixed it 2:1 with water. I was amazed at how well it de-rusted the tank in about 48 hours. I don't know if it is superior as I have nothing to compare it with, but it did a fine job for me. For the next tank, I will try ordinary 5% vinegar.
Great lesson Grand Pop!
There's only so much surface area or rust acetic acid can attack and dissolve at a time any more to a certain point it will just be waiting in the back until the front of the line gets used up.
Same with muriatic acid but that stuff works faster to a point too, 100 percent muriatic acid wont eat up the metal any faster than 80 percent but any acid with more percentage will last longer.
30 percent vinegar will last 6 times longer than 5 percent vinegar walmart vinegar at $3.93 a gallon if you buy 6 is slightly cheaper than buying one 30 percent vinegar.
30% can be dilluted to 5 x 6% for only double the price of regular 6% , so that works out to 4 bucks , right?
Yes, but there's no difference so why bother with the 30%
Finally i found this
Fun video, Tom. I've been told that vinegar will also clean my clean my clogged faucet or shower heads. Have you tried this?
Thanks for the video.
I have not tried it yet but I have heard that also. Maybe that will show up in a future video :-) Thanks
Fantastic video thanks buddy.👍👍👍
Dude, great video! Thanks for sharing.
Try soaking the metal for 24 hours in the higher power vinegar obviously it’s going to work extremely better 💯
Cleaning vinegar @ Walmart as-of January 2023 is $1.99/gal (6%) and is by far the best buy.
Bidin prices 💩
@@piggy310 lol yea the 6 separate trade-wars Trump started could have nothing at all ...or the pandemic or...nah must be dem liberals yet again (too bad you can't blame the Russians for everything anymore as the GOP is their ally now).
Great tips
I can get 80% acetic acid for less than 20 dollars per gallon. Then I can dilute that to whatever strength i need. I doubt those food grade solutions can compete in price.
Thank you
The big advantage of more concentrated vinegar would be
- Space and ecological reasons (less plastic)
- Money (depending on the price)
Easily you could pick up two or three of those and dilute it to make a large vat for rust removal
Awesome video thank you
Well done...
The HDX "cleaning" vinegar is only 5% Acetic Acid. Sez so in the MDS sheet.
Also is heat, both increase reaction speed.
Great tip! Stay skeptical :)
I know im late but ive got a few things to add to this video
1. 24 hours is generally enough to remove rust.
2 .the hardness of the metal will effect soak time. the harder the metal the more soak time will be needed.
3. the severity of the rust will also effect soak time
4. if the dimensions of the item being derusted are important sanding or wire brushing may be the better option
5. vinegar derusting should never be used on aluminum or brass it will eat away a lot of the metal in a 24 hour soak
6. vinegar will damage and in some cases completely remove case hardening
ill close this comment by saying you dont want to 3% acidity vinegar it will take twice as long to remove the same amount of rust that as 5% acidity vinegar
i will further add that i was surprised that the higher acidity vinegars didnt yield better results faster.
ill further add that as im watching this i have a muzzloader barrel that i acquired in a trade soaking in vinegar
How about diluting the 30% to make it 5% and compare with the store bought 5%?
you just saved me $14, where do i send the check :) also don't put rusty bolts in a glass jar and screw on the lid, when you check in the morning you will probably have vinigar, bolts and broken glass all over
I didn't know that. Now you made me want to try ;-)
Great video and results. But how about 5% vinegar with baking soda? Or Some even use salt and vinegar.
I certainly could try that for experimentation purposes but if I get good results just using vinegar why add more ingredients.
Thanks for all the great tips...
What about killing mold on the outside of your house, have cedar siding and some black or almost like mildew and want to repaint the house but it's only trim work
So if you had a 45 gallon tank, would you buy 45 gallons of vinegar or delete it with water,,no way to get inside,,propane tank
Rice vinegar with 4% acidity, Does this work in creating rust water, made by using rusted bobby pins soaked to created rust.
How long have these parts been in the vinigar bath? Can this be used for closed areas like pillars, door inner for classic cars?
Thank you so much for this video
Thanks for the video. Useful tips. Regards
We have here in ballkans 9% vinegar which works very well!
Can you put vinegar in an electrolysis tank?
Thankyou for sharing Sir.
very helpful, thanks
How long did you soak the three % when comparing them all three?
Thank you. Very informative. :)
I just ordered 75% because I need to make a lot of it.... I have water at home no need to pay to have that shipped here!
Why doesn’t he just soak it in the 30% vinegar for 105 mins
Can you reuse the vinegar if preserved in a bucket???
Yes. I save it in a gallon container.
Man, are you really bad at math?
30% / 20$ is 6 gal of 5% or 3.3$ per gallon of 5%, or 17.5% cheaper than buying diluted
1. It's actually cheaper
2. It actually works better although the timing improvement is not linear to the concentration
3. You need to use salt - vinegar by itself is weak
4. Find better rusty parts for a representative experiment
I'm doing this with 5% for the first time on an old Bailey #4 hand plane. It sat in the vinegar for ~24 hrs and when I pulled it there was this grey coating that, when rubbed with a dry rag, was black. I cleaned the parts with hot water and dawn prior. What is the film? Was it not cleaned enough or is the vinegar eating the metal?
Often what happens is the rust has already eaten through the surface coating of a piece of metal. When the rust is removed you are left with a surface that is unprotected. You can clean and then add a coat of wax or oil to keep it from rusting again quickly.
thank you.
Very nice, I have just subscribed to your channel.
Thanks for the sub!
If you boil regular 5% vinegar in a ventilated area it becomes strong enough to where if you touch it it’ll burn your hands.
@@douganderson7002 I guess it’s just in my mind then thinking it works better. Though I’ve tried using Regular vinegar and boiled vinegar and you can visibly see the boiled vinegar just dissolve calcium in the kettle.
I restore axe heads that look like they've been buried in a field for 50 years. When tackling that kind of rust.....add baking soda.
Doesn't that just neutralize the acid tho
I bought double strength! I don't know where to find stronger?
@@douganderson7002 thanks 😊
How long did you submerge the metal pieces at the beginning?
From what I remember it was 24 hours.
@@AlleyPicked Just rewatched the video it was 36 hours, thanks
i will use this in my radiator coolant to clean all rust...
yep cool cause we all want to wait for 12 months for the vinegar to remove the rust.. just awesome!
In many cases, the rust is gone by the time you get up in the morning. No work involved.
What solution can we use to dissolve the black residue that's left after the acid treatment?
try steel wool and a little paint thinner
Now will diluted 5% vinegar work as well? Say 1:5 ?
What's the lowest effective concentration?
The lowest or standard which they sell in the stores is 5%
@@AlleyPicked I mean , to use 4 gallons of water and one gallon of 5 % vinegar? Might that still work, dilute, for bigger parts, time not being a factor?
@@undernetjack I understand now what you are asking. That would be only 1% acidity. I would think it still would have a small effect. Of course that also depends on how badly rusted the part is. Might be a good test to try this on a smaller part like a rusty screw and see how it works.
Sounds like a good suggestion for a video. :-)
@@AlleyPicked I will give it a go with a large project I am working on and let you know. Cheers.
Is rice vinegar okay
As long as it has Acetic Acid in it -- it should work
@@AlleyPicked does rice vinegar? idk what acetic acid is
@@wa-bu3ke Look on the ingredient panel.
@@AlleyPicked It doesn't say. It lists vinegar and water.
@@wa-bu3ke try it and see if it works.
Of course stronger acid is more caustic and will do a better job, that metal was just surface rust, your pee would have de-rusted that lol, ask any high school chemistry teacher If you want weaker and safer just dilute the 30% acidic acid and its 5 times less expensive, or buy 98% acidic acid dilute it to whatever percent you like and get it even cheaper.
Have you tried this with deep rust instead of just surface rust?
Yes. I first use a stiff wire brush or sand blaster, then apply ospho and let it sit overnight. Repeat if necessary.
This would have been a good video if you didn't bring the time effectiveness into the conversation. Expecting something that is 6x in strength to work 6x faster is just flawed logic, it's just a dilution ratio. You also forgot to mention the safety concerns above a 5% solution or cost effectiveness of doing your own dilution with the higher concentrations. There are plenty of reasons to buy the higher concentrations, but you are right that if you use it straight out of the bottle on rust, it's no more effective than any other acetic acid solution.
What oil should you use after removing the rust?
Almost any type of oil will work. Motor oil, Marvel mystery oil. Even a good wax will help protect it.
I should've watched this before I bought a bottle of 75%.
Where’d you find 75%?
Uhhh....it's 1% more.
DOH!!! I bought double strength! Lol.
Oven Cleaner is best.
Vinegar is kids stuff use hydrochloric acid.
Wow! Whodathunk?
Dude you need a chemistry lesson
Go ahead and give us one.
I believe there's a curve. I bet soak the 30 percent for 35 minutes and it will be equal to the five in 105. saturation time, the ability to soak and penatrate. your first test leafs to this theory since it looked better at first. my guess is that if you did the first test, a lot shorter soak time, equal time, the thirty percent would win. try it for me plz.
even very short time even if it doesn't remove all the rust. right when you see the thirty working better, take them all out and rinse. bet the thirty wins. the trick is dialing in the time ratio which is the curve. it may not be six times better because of other variables but I bet it's better.
Did I miss that lesson?
I appreciate the info. Im using the 5% cheapo and it is working wonders for me. How long is too long though?
I don't know if there is a "too long". I never to leave anything over 3 days.
@@AlleyPicked okay thanks for that. So far it has only been a day and a half
