I am sure most of us have heard of and used Evapo-Rust to remove rust from parts and gas tanks. The stuff works great but is pricey if you use a lot of it.

Does anyone know what the active ingredient is? I understand that it is not an acid and removes rust via chelation. That is why it won't harm metal like acids will. The company says it is safe and non toxic so I am guessing it is maybe derived from plants of some type.

Anybody know anything about making your own batch of this safe and effective rust remover?

There is a similar product on the market....I just can't remember the name of it. I am sure it is the same active ingredient so it is not like trying to figure out KFC's 13 spices.

I have read about beet juice and molasses but I don't think that's it.

The other chemical I was thinking of is called Metal Rescue. I think it uses the same active ingredient that Evapo-Rust uses.

Fri Mar 07, 2014 9:12 pm

Phosphoric Acid if it's the same as JASCO.

Use in well ventilated area or with a proper mask.

Nope. It is not an acid. It won't harm people, paint, aluminum, brass etc. It separates the rust from the metal through chelation. It is safe and non toxic........definately not phosphoric acid!

Why not read the MSDS?

I did......so have others. Active ingredient is not listed. That is the reason for the post. Company won't reveal the active ingredient.

If you know it works, why not just buy it and use it? What difference does it make what the active ingredient is?

I've been to the plant that makes evapo-rust. It is made here in my home town. There is a reason that they don't disclose the active ingredients. The inventor told me the process and that it is an enzyme but nothing more than that. They have to protect their secrets to keep people buying it from them. But it is really cool stuff. He has a huge vat of it and said anytime I needed to derust something just to bring it by. Really nice people.. he is also working on a formula to remove corrosion from aluminum and magnizium.

Thanks for the reply. That is what I was wanting to do is have a 50 to 100 gallon tub in the corner of the garage to dunk parts like drums, exhaust, tanks etc. To buy the chemical to fill the tub would cost around 2k........so I thought if I could make the rust remover myself cheap enough a dunk tank would be feasible.

Here are two possible solutions.

http://frugalliving.about.com/od/cleaningtipsandrecipes/qt/Rust_Removers.htm

Here is a guy that, after wire wheeling the rust, uses vinegar water as a surface prep. He says that it turns, or neutralizes the rust, just like por15.

Would a big tub of vinegar work or a combo with Borax?

Post back your thoughts. I am curious if this information helps.

Thanks *bird for the videos. The Evapo-Rust doesn't really smell vinigery but it does turn the metal a dull grey to black in some areas. There is a video of a guy on you tube that purchased molasses for 17 cents a gallon at his local Ag feed store. The molasses takes about two weeks to remove rust. Evapo-Rust does the job in about 24 hours.

The previous poster said it was a enzyme. I will start researching plant enzymes and see what I come up with. As I said before there is more than one product on the market that does the same thing (just search YouTube) so its not like others don't know what the active ingredient in these non toxic rust removers that use a chelation to remove rust.

Yeah, but we know how to weld and restore and stuff properly :) :)

...nearly forgot...you have the Metal Surgeon...oh yeah, he's English :)

I see your chequered floor and raise you one hacked rear Jersey looker rear wheel well... :)

Good thread...my own rust remover of choice is near-pure Phosphoric acid, but it's hellishly expensive and nasty to work with in concentrate form. Does the job like nothing else I've tried over the last 6 years.

The good thing about molasses is that you can put it on your pancakes while it works on the rust....

Ouch, man! But in our defense there are few, if any, JLs being restored to their original JL condition. At least I hope so.

And thank you for themetalsurgeon!
