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

This product really is awesome. I’ve used it on a variety of projects and it removes even the worse rust overnight. It’s terrific because you can use it over and over multiple times. A real value and useful item in any shop.

I have never encountered this substance before. People probably want to know if it actually works. It seems it does. At any rate the rust is being removed, which I believe is the intention. It does take time -- a few to many hours -- but given that it is non-hazardous and reusable, there is no complaint on speed. Others here have written of its virtues and methodologies, so Ill not repeat them. But it is remarkable enough that I feel compelled to contribute five stars. I imagine this chemical will be standard issue for any workshop or utility closet, as it is hard to fault.

Used 2 gallons to clean up a pair of engine heads and it worked like magic. Soaked them for a few hours overnight just to be sure, and they look good as new. Cheaper than big box stores and received earlier than estimated.

As the directions say, it can take 24 hours of soaking to remove the rust but it does a good job given enough time.

Got turned on to this stuff from Adam Savages Tested show. My girlfriends father picked up an old Sega Genesis and Sega CD expansion unit. It had some issues and while taking it apart to fix it I noticed all the screws were orange with rust. Threw them all in a small disposable plastic container with some Evapo-Rust and they were completely clean in about an hour (Gotta shake it/move the parts every little bit). Gonna start going through some of my old rusty tools and cleaning them up with this stuff too. One of the best parts is this stuff is its reusable. If its not too nasty from whatever you were cleaning, just pour it back in the bottle and use it again.

This stuff works great. I used it on a metal gas tank from the 80s. I put a gallon of this in it, rotated it into different positions once a day for a week and its darn near spotless inside. Will be using again.

I was worried about the eco-friendliness, however, I figured Id see what all the internet hype was about. This stuff works great. Will remove the rust off just about anything in under 24 hours, and will do it faster when warm. Worth every penny.

I used this to de-rust a bunch of old tools, drill bits, etc. it worked just as advertised. Was nice knowing it’s not a dangerous chemical so getting it on hands or dripping a little wasn’t a concern.

Works better than expected, rust just comes right off and leaves a good finish. I saw it used so many times on the rebuild videos I just had to see if it actually is as good as it looks and it is. It does work slowly and soak time can take a really long time but its worth it. You will also need a lot of it as if you soak something that is not submerged it will leave an etch line. I did some really rusty and corroded calipers that cleaned up inside and out.

Immerse parts in it overnight and rust is gone and the parts arent turned black like Total Boat or another one I have used. For parts that cant be removed and you spray it on you will have to continually be spraying every 15 minutes to 1/2 hr. This method takes a long, long time. It is a slow-rust remover and also as it is evaporating you will go through a gallon. For parts that can be immersed, it works great.
