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

I have been purchasing this product for years from Harbor Freight. With COVID-19 upon us. I am glad I can purchase the product online. I restore old cars for a hobby. When I am done with product and residual rust particles accumulate in my soaking bin. I use it to make my lawn stay greener. Clearly the lawn luvs it based on the grass turning a lusher color of green.

I really like this product and recommend it for those derusting jobs that cant use an acid or electrolysis. This is a chelating agent that just sucks rust off your part. It works, and works fairly fast. But you dont want to use it on chromed parts. It just pulls chrome off. I was disappointed by this. Its good for zinc coated parts that would react with acid derusting liquids. You also really need to be able to submerge the part, so working on a large part is pretty difficult. They say you can wrap big parts with soaked cloth or towels, but that doesnt work in my experience because this stuff evaporates too quickly. Also! Dont spill this on concrete! It will permanently stain (whiten) concrete. Get some because it works fantastic on aluminum and aluminum alloys!

If you have ever had to remove rust from your tools because your spouse placed bleach into the dehumidifier bucket of your tiny excuse for a workshop, you need this stuff. A few years ago I tried another brand from the local big box hardware store, thinking no way an aqueous solution could remove rust. Well, more precisely that it may remove rust, but then rust anew. I was pleasantly surprised when the instructions said it was OK to leave items in (albeit that a black layer of protective material would be left behind on the previously rusted metal). This stuff works and it sure beats using naval jelly (phosphoric acid) or oxalis acid, both not exactly non-toxic, with improved results compared to the two acids. Especially if you are absent minded and forget about soaking the item for days at a time. I keep a plastic lunchmeat (like Costco sells in their refrigerated section) container about 1/4 filled and toss the parts in. Come back the next day and the rust is gone. Longer, and it has a black layer of something that is not rust, but can be abraded off. I often just leave the layer on, but be forewarned that the black layer will often remove the chromed layer. That is the only real negative, other than it does deplete itself. It is also not easy to apply to larger items, unless you get creative with saturated paper towels, and plastic wrap/bags to prevent drying. Highly recommend.

Ive always wondered how this product does now I know...it works amazing I had some rusted tools that I never wanted to throw away took the rust off with no sanding all I had to do was just wipe.

I used this to de-rust a motorcycle gas tank. Worked like a charm after letting it stand for several days.

5 stars may be generous. It did work to remove LIGHT rust from inside a GSXR motorcycle gas tank. But takes longer than directed. I followed the directions up to the point where it says let soak 1 hour. One hour had no effect so I just left it alone for the rest of the day. Gave it a good shake before bed... The next morning I took another look and saw some IMPROVEMENT ! Gave it a good shake... For the rest of the day, shook it up every couple hours, then it was even BETTER! Good Enough... It works for light rust. It just took longer than directed I then followed the rest of the directions for cleanup, just wash with clean water. Nice and easy. Then I used compressed air to blow all the water and residue out. The tank was clogging the filter before and now looks good enough to use so I am happy,

I use Evapo-Rust as part of clock cleaning, to safely remove rust from rusty gears, levers, gongs, and chains. I does a wonderful job, and seems to leave lacquer in place (such as the gold-colored lacquer on many cuckoo clock plates). Be aware: it does remove bluing, because bluing is a form of controlled rust (oxidation). However, I find it easy to re-blue cuckoo clock levers and such using a cold bluing product such as Perma Blue.

This product is AMAZING. I work a lot with rusted pieces and this has done the best job so far of any product that is out there.

Can take hours or overnight, but it works well, and seems much less caustic/toxic than the traditional rust removers. Can use it without gloves

This product absorbs only the rust while leaving the steel alone. I used it to clean rust from a tractor diesel tank before using Redkote to seal the inside because of pinhole leaks.
