Cleaning Rust Off of Tools Without Harsh Chemicals

[rleete]

I get glacial acetic acid from work. The stuff smells like plain old vinegar (if a bit on the strong side), but is many times more concentrated.

For those who don't know, "glacial" means they take all the water out of it. Not quite "eat your skin as soon as you touch it", but you really don't want to be sticking your bare hands in it either. Works the same as store bought vinegar, but at a much accelerated pace. Meaning I don't have to let a part soak for days, just hours. Works about as fast an as well as naval jelly, but it's free.
