Magic rust spray. My secrets revealed.

[@danherring5676]

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

[@bluemule3891]

@@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.

@@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.

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.

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.

[@wymple09]

No, that's rust converters. Phosphoric acid is a rust destroyer. 2 different animals, I use both depending. I like the converters on light rust.

[@ThePeaceableKingdom]

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.

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.

[@justahandchannel]

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.

Apologies if answered already or if asking a silly question... If this spray acid/eth alc mix gets on gaskets /seals, does it destroy them? I'm thinking differentials, heads, intakes, transmissions, etc... not carbs, egr, etc...

[@justahandchannel]

I've never had a problem with any of those things.

[@geraldreid6395]

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....

[@stanleylosh1899]

I like it. But what is the ratio of acid to alcohol? I assume 60 % is the strength of the acid, not the recipe?

[@stanleylosh1899]

I just found your reply under jackrichards comment. 60% acid, 40% water, then add 5% alcohol.

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. 🤣

[@justahandchannel]

Thanks

[@r.perkins2103]

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).

[@justahandchannel]

Citric acid works great on light surface rust but not as effective on deep embedded rust we get in Ontario

[@BC5391]

If you ever use Epoxy primer, you will never need to use etch primer, just epoxy over bare metal

[@justahandchannel]

Exactly!

[@billyray6913]

Thank you sir. How much of each chemical?

[@justahandchannel]

95% and 5%

[@jasperthehairycaterpillar1168]

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 am a bit confused about the mix. Do we purchase a bottle of 60% phosphoric acid and a bottle of 5% ethyl alcohol if so at what proportions do we mis the two. Does it matter? Thank you 1:36

Is rubbing alcohol a good substitute for the ethenol?

I've never tried it. Not sure what the results would be but why don't you give it a try.

My question is, will it potentially damage brake and fuel lines? Or, will it actually extend the life of them?

Well I wouldn't think so. I haven't seen it do any damage to anything but painted surfaces

After applying, is there black residual leftover on the steel which needs rinsing cleaning afterwards? I like to do inside a hard to reach cavity and scrubbing will be difficult.

As long as you're not starting with a flakey surface, there is no need to do any prep before paint

[@justahandchannel]

You can use Either.

I have been using the Behr Concrete Cleaner but found out it isn't phosphoric acid. Its some other acid. I wonder if I was damaging my parts. It really rusts fast after.

[@justahandchannel]

Another comment suggested that behr have changed their chemical compound. It may no longer be a source of phosphoric acid

[@davidotness6199]

Not to detract from your formula at all, and I do appreciate your formula, but Corroseal is an excellent albeit even more expensive than OSPHO rust converter, and it also adds a durable priming surface. I've used it on commercial fishing boats in Alaska and it by itself holds up amazingly without further painting. Just adding to the mix. Thanks for this video.

[@shanemoves2567]

Would you recommend do this 1st then Corroseal for a Semi truck frame/hardware and rv frame/hardware? Overkill or even more protection? Sry 4 my ignorance on the subject.
