The big danger of evapo-rust is failing to have your parts fully immersed. That can lead to an etch line at the surface as the oxygen in the air attaches to the steel and the evapo-rust tries to take it off. Also, if the items are painted, the evapo-rust will soften up the paint. So let the part dry completely before you start trying to brush off the residue. Even a nylon brush will take the paint off while its wet.
If you use a heated ultrasonic, it just takes 30 minutes for most parts to completely clean up, and for the worst, another 15 minutes is usually enough. It works so quickly that way that there’s no staining. Some guys make the mistake of not immediately washing the parts off and then that black film will stick and can be hard to remove. Just never sand or Scotchbright it. These thing are accurate to tenths. Once they rust the need to go on the surface grinder to be brought back.
Old tools that I have used Evaporust on always clean up well. Polish with Scotch brite, steel wool or fine emery will take off the black "tarnish". AL B.
Evapo-Rust is a mild chemical and seems to have a detergent mixed in. I would wash your hands off afterwards, but it shouldn't pose a great deal of problems for skin contact.
They look like some good finds. Chunks of metal are always handy to have in the shop.
Very interesting. Nice work sir. Good as new
I've been thinking about buying some but I've been on the fence.

I left a container of evapo-rust for 2 years it stunk pretty bad but a wire wheel cleaned it up.

I have had good luck using Dawn Dish Soap and warm water and a Scotch Brite pad. Thanks for the video
I've yet to use that juice. Maybe someday I'll give it a try.
Is that really a good idea? Evaporust on bare skin?
