It's been an education to move to the humid South after living in the dry Colorado air for soo long.
I have a bunch of squares, protractors, rules, tools and all my reloading gear that was getting attacked by humidity in my shop.
Evaporust to the rescue!
This stuff is non toxic, non acid based, safe for hands, reusable and it works!
Submerge overnight and maybe a little scrub with a plastic kitchen scouring pad. A water rinse and you're done.
I'll be more focused on keeping things lubed to avoid rust and adding more vents to my shop but I'm happy to have a non toxic way to strip the rust off my tools when necessary.
