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

@bluemule3891 10 ай бұрын

@@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.

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 10 ай бұрын

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.

@Harry-kw1fy 2 ай бұрын

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 2 ай бұрын

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.

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.

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.

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?

Good video, but I missed something here.... 1. Take 60 percent concentrate phosphric acid and 5 percent ethyl alcohol. 2. What I dont under stand is that, is the ethyl alcohol concentration 5% or its the ratio of mixing both liquids( I mean mix 95% phosphoric acid to 5% ethyl alcohol??) or 5% is just the strength of the ethyl alcohol? Can someone help?

@rob12449 9 ай бұрын

I'm guessing too, but it seems the 60% is the concentration of the acid (does vary by brand) and probably it is 95% of blend with 5% pure ethyl alcohol, which I believe is also called ethanol.

@justahandchannel 9 ай бұрын

The phosphoric acid i use is 60% concentrate. Mix whatever concentrate you have at 19 parts and add 1 part ethyl alcohol.

@rayray2615 9 ай бұрын

@@rob12449 Yeah, the same guy made the second video to clarify the ratio. He said the 5% Ethyl alcohol is the hand sanitizer, which further confuses the issue. I would buy both the liquids, then mix them in front of the camera to remove all doubts.

@justahandchannel 9 ай бұрын

I did exactly that in the second video.

@quinncox8923 4 ай бұрын

5% of the total volume (mixture) is the ethyl alcohol used as a thickener to help the spray cling to the metal. I would assume xanthan gum would work as well

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.

Will isopropyl alcohol work as well or does it have to be ethyl alcohol?

I've never used isopropyl alcohol so I'm not sure but you can use hand sanitizer which God knows plenty of us have lots of that left over

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

@michaeldecker2725 10 ай бұрын

Do you know if this effective on scaled rust such as under a truck? I have a 20year old truck with heavy rust I would like to arrest. My thought is if this will “clean” the metal enough for me to put a protective coating on it (I.e. NHUC).

@justahandchannel 10 ай бұрын

If it's very scaly I would recommend at least take a wire brush to it to get anything loose off. Ultimately a wire wheel on a grinder can do a pretty good job of smoothing it down first and then apply the product and you will get much better results

When I owned my Chrome plating business I was liscenced into buy chemicals and acids at industrial percentages. Like Muriatic and Nitric and sulphuric and phosphoric. When used at industrial strength the Phosphoric would smoke on ferris materials and instantly turn the iron black. With my Chrome business and boat mfg business I had to run a serious gambit with the state fire marshal staff to qualify the purchase and storage and use of those chemicals. Now at 80 years old and retired I don"t know where to get these products in industrial strength to use in my home shop. Do you? Thanks Dandahermit

I use it in the sun, the shade, the snow, the rain, the hot, the cold, in the dark, in the light, in a box with a fox, wearing socks. It doesn't really matter. It does the same thing no matter where you use it. As far as keeping it wet, that's not necessary at all. Once you've made contact it's over. It's just a matter of time
