Evapo-Rust ER012 Super Safe – 128 oz., Non Toxic Rust Remover for Auto Parts, Hardware, Antiques | Rust Removers and Chemicals

This stuff is the bomb! Re-usable until it isnt. I know, that sounds weird. I had a 3.5 gallon bucket that lasted for about 5 years and got many, many, uses out of it. Eventually the liquid becomes saturated with particulates from items that were not necessarily cleaned well. This material eventually builds up in the solution. Because of the way it works, chemical chelation, I imagine the solution eventually absorbs enough oxidized iron that it will stop working. When it no longer works, the product is bio-safe so it may be dumped down the drain (so long as it is not full of other automotive chemicals such as anti-freeze, oil, etc.). Rinse out the 3.5 gallon bucket and refill with fresh product from the 1 gallon jugs. Just make sure you clean as much gunk, grease, oil, residue, etc. off your piece before you soak it. This will keep your solution usable for a LONG time.

Worked well for cleaning my rusty 1979 Puch Maxi moped gas tank. All is good now

I cant explain why this stuff works but it does. Ive used it several times to remove surface rust from bolts/screws. I left them soaking 24-48 hours and impressed with how they came out.

Had a vacuum blower motor for a carpet cleaning machine seize up. Attempted with gallon of pb blaster to soak and free up but still wouldnt budge. Used this and it safely removed the rust and now an expensive teardown has been averted.

This stuff is simply amazing. I had a large amount of rusted shut tools. Soaked them for around 24 hours and they all came out working except for one and it went back in for more time. The other tools and nuts and bolts just had a lot of rust and they all came out looking brand new. What was still on there came off with a steel wool. I highly recommend this and will probably kee a gallon or two stocked on my shelf for future use!

I poured this into a large cooking pan and set some old rusted arcade parts into it and it came out nicely.

Im not sure why I waited so long to try Evapo-Rust. Im literally running around the shop looking for things to remove rust from now. Im near the coast and we know what salt and humidity do to metal tools. The pics are less than two hours apart and Im seeing a world of difference.

This product does remove rust when fully submerged, but it takes a long time. I had to soak some old bolts for about 2 days to remove the vast majority of rust. Once the fluid takes on rust, it is basically useless, so I dont think it is fully reusable like they claim. If you have small parts you can fully submerge, I would recommend it, but for on-the-car stuff, this isnt going to be the best option.

Worked on alot of bearings, bolts, assorted steel, and iron items, some though grew a type of black fungus after a while and some became more prone to rust after a couple days but in rhe end id get it, it works for most stuff

I used this to remove rust from my table saws cast iron surface and interior and it worked well. Love that its nontoxic and reusable.
