I used phosphoric on some rebar 8 years ago, to use on the deck rails as balusters. First a soak in phosphoric, then some Rustoleum spray primer, and then a good couple coats of spray undercoating. Those balusters look like new after 8 years out in the Alaskan weather. The acid did a perfect job etching so everything stuck extremely well.

Hi, great vid, a couple of interesting facts about phosphoric acid, the end products of this acid and iron oxide (rust) is Iron Phosphate, that is the black color we see, it is very stable and you can paint right over it, the other product is water, so, in general, you are correct, for a strong chemical it is pretty "safe", compared to red fuming nitric acid (don't ask how I know) 😁😁 I like to spray it down with a mix of baking soda and water, about two tablespoons per quart, just to be sure we are 100% neutralized, but that's me, no official studies just gut feeling. Also if someone wants to reduce it, always add the acid to water, never the other way around, and no I am not going to talk about mol's here, just use percentages, or parts, like mixing paint. Thanks for the video, with all of the nonsense that is on the internet about rust removal it is refreshing to find someone who gives practical guidance. Be Well and Successful Blue Mule
@@krhunt1014 when the surface is dry, I wet it down with the baking soda solution. I bought 2 pounds of Sodium Bicarbonate, waayyyy cheaper "Baking Soda". By the way I actually use Ospho for body panels, it has dichromates, and "wetting" agents. The dichromates help with changing the iron oxides into iron phosphate, and the wetting agents help the solution to "stick and spread". This is especially important in body panels and vertical surfaces, but for hard parts, brackets, etc. Yeah the 30% Phosphoric acid and water is the bomb. Be ready to prime, the acid does the chemical reaction on the rust, but you really don't want it to sit without primer. I like to mix a DTM primer, and reduce it to almost a sealer, to just get the surface covered. Anyway more than you asked for, my apologies to "just a hand" for taking over the comments section, I am of German decent so it is in "Die Blut" 😁 Blau Maultier
@@zoneundertop I had no idea there were sooo many choices😀 946.352........ I would just use 1000 ml and call it good, just enough to neutralize and stray acid, and bring the surface to more or less neutral. Remember this is a personal thing, and is not really in any product instructions. But because of the work involved in prepping a car for a good paint job, I don't want any, as Jon Kozmoski would say 'Deterrence" to a good finish. Remember also if you are doing a door, etc. wash it down inside and out. Blue Mule Oh, if you want to see how bad it can get with improper prep, see "my friend pete" and his cutlass disaster, his language is not for the faint of heart though. Also I think Pharraway also had a paint match/prep issue. It is a lot of work on top of a lot of work.
I'm not a chemist but I think the process turns the rust to iron phosphate. Some firearms use this same method for a finish that deters or prevents rust on steel surfaces. Thanks for video.
I believe you are correct. Phosphoric acid converts iron oxide into iron phosphate. Iron oxide is not water soluble, but iron phosphate is; after the acid has done its work you can wash away the 'rust' with water. The iron phosphate also acts as a good surface for paint to adhere to, and as a dryer for oil based (alkyd) paints. I did this on a rusty old set of scaffold - wire brush (by hand, not motor), phosphoric acid, garden hose, rusty metal primer, and a coat of red enamel. 35 years later after heavy use and outdoor storage the scaffold is scratched and dinged here and there, surface rust in the scratches of course, but still red and still going strong.
A mechanic warned me about rust on my truck frame. It's not bad, but it's getting there. I was planning to do some elaborate work with wire wheel, which wouldn't get to numerous places. This method will save me a lot of trouble. Also, the warning in the comments about avoiding it on spring steel may be very important, so kudos there, too.
Great video and idea!! As a NY state resident rust is a big expense up here…. I’m so glad I saw this …. Because I’m making it and using it on my rusting expensive vehicles…. Thank you kindly soldier! Semper Fi!
Doing a driveby and saw this video ! I need to an Idaho truck and was ready to call a body shop.. I gotta try this. Great comments and thanks for your efforts and clarifying
I have just about gotten away from chemicals with the exception of a few cases where electrolysis isn't feasible. Electrolysis is clean and doesn't miss the smallest hidden spot. I enjoyed the video and will use your idear where needed.
Thank you for your great video, just when I needed it! I certainly will use it on quite a few items I have here that surface rust is an issue. Merry Christmas to you,!
Thanks very much for this extremely helpful instructional video. It solves a very common problem, saves money and time, Brilliant !! Much appreciated !
I used ospho years ago when helping build a dock out of thin I- beams steel. We painted after with 3M epoxy primer. The beams were secured to large tubular floats The floats were later removed and the frame work was suspended with winches. It didnt rust for years.
I have used that product and it's probably the most effective on the market. But it's only 18% concentrate and I wanted something with a little more kick to it for a fraction of the price. I can make 9 gallons for the price of 1 gallon of their product and it's three times stronger so therefore it could be diluted to 27 gallons for the same price as 1. The chemical makeup is almost identical.
Well done, your video was excellent and very clear in spite of the things you consider to be errors.. your message definitely got through and your ideas are great thank you
An aside: Don't use this on spring steel (springs) - it changes the grain structure of the steel and cause them to break because of stress concentrators in any pit and because of the grain structure change itself. (Just wire them off.) Same applies to roller chains because of the case hardened steel.
Well, I've just done this treatment to coil springs, we shall soon see what happens... The coils are relatively thick, and I'm not entirely convinced the acid can penetrate very deep into the metal. Surely it will affect the surface layer, but the whole spring, dunno..,
For me, it's about preserving history. I want to bring back as many as I can so that when I'm long gone, those cars are my legacy and the little impact I made in the world.
Thank you. I have used concrete etcher. It's cheap and works hands down. It dissolves and neutralizes rust. Put in spray bottle and saturate heavily. Let it sit overnight. Money
Did paint & body for 35 years, used that method all the time but take note, many epoxy primers and most body fillers are not to be applied directly to the acid etched surface. Some can but many suggest abrasive cleaning, sand blasting or grinding.
Yes. It doesn't have to be 60% concentrate. Ospho is only 18%. What I forgot to mention in the video is you can dilute the formula to a third strength with water as well
Your SPOT ON using epoxy primer... sadly governments have removed the “ Chromated” epoxy primer... The only thing that degraded that was ultraviolet! Great video, THANKS‼️🇨🇦👍
My method is using HCl in a spray bottle, using rubber gloves and eye protection. After rust is dissolved, I rinse it off with a water baking soda mix, don't use only water or it will flash rust after drying.
This is awesome. I had considered sand blasting the surface rust of an old trailer frame I'm restoring. However, after watching this, I plan to use you secret formula. BTW, don't worry about your hair. At least you still have yours. 🤣
I just spent over thirty dollars for a small can of etching primer,which works very well,I must say,but I can't wait to try your formula. Thanks for reminding me how hard it can be on painted surfaces. Thanks also for your easy-going manner. That's my speed. Loved your video and am looking forward to seeing more,Lester. By the way, I noticed a Tim's cup. Are you Canadian?
I can testify this is really good stuff! One thing I'd add is use this outside, or wear a respirator with a good filter. Got myself a nasty cough using this inside... Locally (Finland) this is also availlable in gel form, so it really sticks to all kinds of forms.
Yep phospric acid is the active ingreadient in a product called Rust Buster. Ever since ive been looking for Phospric acid its sky rocketed in price as more people become aware of this. Should be ok with Metholated spririt huh. Also Rust Buster ssys to clean off any extra resedue with a damp cloth after before painting over. Also says take back the heavy scale rust before application. Becarfull ive left this sitting in a tin bowel over night and it ate holes straight through. So be mindful of where and how to apply it. Use test pieces.
Seeing as soft drinks contain phosphoric acid and they come in a tin can I can't see how that is possible. That product must have something else in it that caused this
I am advised by another youtuber - someone who has used this for years in a commercial operation, so perhaps every week - the concentration of phosphoric works better if it is 8 - 12 percent. This is because you need Hydrogen ions in the water to be added and free moving, for maximum efficiency. This affects greatly the reaction that takes place. Cut the phosphoric with water - adding the acid to the water not the other way round. And - do NOT wash off with water. The only acid you don't remove with water - the acid binds to the surface and protects. Be particularly careful if considering applying to threads and springs.
I concur that exposure to oxygen is essential, however, the concentration of acid does not directly influence the level of oxygen exposure achieved. This assertion lacks logical basis. While dilution may be attempted, for optimal outcomes in the treatment of severe rust, I recommend adhering to my prescribed method.
BIG Thank you for this ! I live in Northern Maine where we sand and salt the roads. We often undercoat with fluild film or wool wax. I have a truck I want to clean up some existing rust. I will use this method , do you see any problem with then going over with wool wax ? Thank you , you’re awesome I just subscribed.
I’ve used 85% phosphoric acid for years on vehicles , I brush or spray it on welds and new steel leave it to dry and then just wire brush and residue off before epoxy primer , I have found it way longer for rust to appear if it even does . I also add it to oil or waxoyl before spraying into chassis or body cavities or even the outside of chassis seems to work great
my guy. This is 4 u. Save oil, trans fluid from services or get a quart of each from friend. Get a tube of grease and 1 wax ring gasket for toilet or 2. Mix and heat in old pot and spray this. I'm 3rd gen who uses this. I use on customers cars. It lasts years and years and costs $10. If that. I've tried and tested blaster, wool wax, fluid film, etc. All work, BUT they have no petroleum products in them. The old farmer trick of used oil and dusty road etc is true. But add a few more things and it's about perfect. I knock off scale and heavy, Ospho it, and then use JD equipment black with hardner, or farm implement paint with hardner, or Eastwoods chassis saver etc. Then bought a cheap undercoating sprayer online or make urr own easily and spray that crap everywhere. My Pap used it, Dad uses it, I use it. It really works very very well. Since cash for clunkers, leaders in wash, a good auto is thousands. Add rust from salt and cars last less than a decade. With this u can make them last as long as they run. Have a gr8 day. I don't know it all but being a car guy, antique guy who's sandblasted, restored, painted alot of crap with wheels, tracks, or just metal, without killing rust, and gr8 base, paint, and oil based wax, it won't last long.
@@krashanb5767 Any. A tube that goes in a grease gun, a tub like u use for packing bearings or use on like brake sliders etc. If u get cheap or on sale grease, with used oil and trans fluid, u can do a auto for less than $8. I mean I've tried about all wax products and yes they work but compared to this mix it's night n day.
@@krashanb5767 Also if urr serious about this look into master coat rust prevention coating. It's not alot of $$ and it was designed to work on bridges in NJ. It's about tge best u can buy. But if u really kill the rust, and get some good layers between the metal and the elements, it'll last a long time.
Great information. We used to buy a paint in red oxide or grey color dubbed PA14. First the concentration was reduced following complaints about the strength of phos acid. It certainly etched well and destroyed any surface rust beneath it permanently. Anyway this you provided is great honest information and i presume the remaining 35% is H2O. Thanks.
@@justahandchannel I have a rusty old machine that's going to get the treatment all over the piece. The name says TEREX. I must have been the only man thick enough to attempt it. But I'll do more than attempt it. It's a commitment now.
Thanks for the tips, especially not using etching primer because of body filler. That one might have saved my paint job and I will use epoxy primer. I have a very important question about the seals and gaskets. Is there any deterioration on seals and such? I want to spray down a semi truck rear end after some pressure washer sand blasting of the frame prior to priming and paint. There are electrical wires and plastic air brake lines, and a couple brass fittings. I release you from any liability, just would appreciate your opinion. I did some grinding and where I did the metal flash rusted quickly.
I've never had any kind of problem with stuff like that. It's not that corrosive of an acid. Would you be concerned if you poured Coke on it? It also contains the same chemical
Also plain citric acid solution is great for submerging smaller parts, or if you can keep the area wet with it using paper towels. Wash off with concentrated tea - yes tea - for the tannins to prevent it flash rusting. (Tannin in vac-tan and fer-tan).
looks like it works great. What proportions of the two solutions are you using? I can buy 60% phosphoric acid and I can buy a solution of 5% ethyl alcohol but how many parts acid and how many parts alcohol? And what is the alcohol used for in this mix?
I've used the method you have here. I would sudjest to not use a zinc coatings or paint with acrilic paint due to residue attack. Appropriate coating would be enamel paints.
lol, “ I wouldn’t drink the stuff”. Check out ingredients of some sodas, such as Mountain Dew. Phosphoric acid. It takes several coats and warm weather. Keeping the effected area wet and warm works best. If you let it dry it converts the outer layer but if you remove it there is rust under that converted layer unless you have just light surface rust. All the rust really should be converted. Will last much longer that way.
I used phosphoric on some rebar 8 years ago, to use on the deck rails as balusters. First a soak in phosphoric, then some Rustoleum spray primer, and then a good couple coats of spray undercoating. Those balusters look like new after 8 years out in the Alaskan weather. The acid did a perfect job etching so everything stuck extremely well.

Did paint & body for 35 years, used that method all the time but take note, many epoxy primers and most body fillers are not to be applied directly to the acid etched surface. Some can but many suggest abrasive cleaning, sand blasting or grinding.

So 60% concentrate phosphoric Acid mixed with 5% Ethel Alcohol.

I also add it to oil or waxoyl before spraying into chassis or body cavities or even the outside of chassis seems to work great
my guy. This is 4 u. Save oil, trans fluid from services or get a quart of each from friend. Get a tube of grease and 1 wax ring gasket for toilet or 2. Mix and heat in old pot and spray this. I'm 3rd gen who uses this. I use on customers cars. It lasts years and years and costs $10. If that. I've tried and tested blaster, wool wax, fluid film, etc. All work, BUT they have no petroleum products in them. The old farmer trick of used oil and dusty road etc is true. But add a few more things and it's about perfect. I knock off scale and heavy, Ospho it, and then use JD equipment black with hardner, or farm implement paint with hardner, or Eastwoods chassis saver etc. Then bought a cheap undercoating sprayer online or make urr own easily and spray that crap everywhere. My Pap used it, Dad uses it, I use it. It really works very very well. Since cash for clunkers, leaders in wash, a good auto is thousands. Add rust from salt and cars last less than a decade. With this u can make them last as long as they run. Have a gr8 day. I don't know it all but being a car guy, antique guy who's sandblasted, restored, painted alot of crap with wheels, tracks, or just metal, without killing rust, and gr8 base, paint, and oil based wax, it won't last long.
@jasonchristopher2977 what kind of grease for this mixture?
@@krashanb5767 Any. A tube that goes in a grease gun, a tub like u use for packing bearings or use on like brake sliders etc. If u get cheap or on sale grease, with used oil and trans fluid, u can do a auto for less than $8. I mean I've tried about all wax products and yes they work but compared to this mix it's night n day.
@@krashanb5767 Also if urr serious about this look into master coat rust prevention coating. It's not alot of $$ and it was designed to work on bridges in NJ. It's about tge best u can buy. But if u really kill the rust, and get some good layers between the metal and the elements, it'll last a long time.
Why used oil? Wouldn't contaminates be detrimental?
Thanks and God bless you
Great information. We used to buy a paint in red oxide or grey color dubbed PA14. First the concentration was reduced following complaints about the strength of phos acid. It certainly etched well and destroyed any surface rust beneath it permanently. Anyway this you provided is great honest information and i presume the remaining 35% is H2O. Thanks.
It's 60% phosphoric acid and 40% water. Then you add 5% volume of the whole mix of acid and water of ethyl alcohol.
@@justahandchannel I have a rusty old machine that's going to get the treatment all over the piece. The name says TEREX. I must have been the only man thick enough to attempt it. But I'll do more than attempt it. It's a commitment now.
TEREX = @@jackrichards1863 TORQ MONSTER...
Like a piece of earth moving equipment?
its def safe for the enviro. water imm dilutes it to a neutral base and thus harmless. great vid sir ! stormyjoe
Thanks again!
Tim Hortons cup? Fellow Canuck.Props,Sir.
Thanks
good job on vid no bs gonna try it out thanks eh
You won't be disappointed
Very interesting need to try this out on the car. Question for you do i need the Ethel alcohol or ok to use 60/40 water? Thanks
You can use it without the alcohol but it won't have the same effect.

Thanks for subscribing!
@@justahandchannel Keep up the great work. I really respect you for the great work that you are doing.
Thank you so much!
My dad complains about rust, since he's always building something. Will definetely show him this.
rust never sleeps...
He will love it
Thanks for the tips, especially not using etching primer because of body filler. That one might have saved my paint job and I will use epoxy primer.
I have a very important question about the seals and gaskets. Is there any deterioration on seals and such? I want to spray down a semi truck rear end after some pressure washer sand blasting of the frame prior to priming and paint. There are electrical wires and plastic air brake lines, and a couple brass fittings. I release you from any liability, just would appreciate your opinion. I did some grinding and where I did the metal flash rusted quickly.
I've never had any kind of problem with stuff like that. It's not that corrosive of an acid. Would you be concerned if you poured Coke on it? It also contains the same chemical
Why do you mix alcohol in the Phosphor acid?
I've never seen your vids before. I thought your hear looked just fine. But I know what you mean.
Thanks for the info.
You're welcome. Stick around and you will get to see a lot more
Also plain citric acid solution is great for submerging smaller parts, or if you can keep the area wet with it using paper towels. Wash off with concentrated tea - yes tea - for the tannins to prevent it flash rusting. (Tannin in vac-tan and fer-tan).
Citric acid works great on light surface rust but not as effective on deep embedded rust we get in Ontario
OSPHO works pretty good!
This works better for a Fraction of the cost.
This sounds like a great solution. What ratio do you mix he two chemicals? I am ready to mix some up and get some great looking metal....
This video will clarify all your questions. Thanks .

I’m going to review the video so I can check out your hair! 🤭🤗😆
🤣
136000 plus views in 1 month excellent video.
I hope the whole world can see it so I can save everyone lots of money and Blood Sweat and Tears
"...wear gloves..." thought he was then going to point to his missing arm 😂
I thought about doing that for the video but some people take things way too literally 😆
looks like it works great. What proportions of the two solutions are you using? I can buy 60% phosphoric acid and I can buy a solution of 5% ethyl alcohol but how many parts acid and how many parts alcohol? And what is the alcohol used for in this mix?
Please watch this video for more detail

I've used the method you have here. I would sudjest to not use a zinc coatings or paint with acrilic paint due to residue attack.
Appropriate coating would be enamel paints.
If you use a good epoxy then you can topcoat with any paint and be confident it will not rust again...ever!!
lol, “ I wouldn’t drink the stuff”. Check out ingredients of some sodas, such as Mountain Dew. Phosphoric acid.
It takes several coats and warm weather. Keeping the effected area wet and warm works best. If you let it dry it converts the outer layer but if you remove it there is rust under that converted layer unless you have just light surface rust. All the rust really should be converted. Will last much longer that way.
