Vinegar has been mentioned before as a rust remover, but this weekend, my dad got out some of his old files and drill bits that were orange. Covered in Rust. I took one of my moms cake pans, filled it with vinegar, put the files and drill bits in the vinegar. I then put a piece of plastic on the top and let it sit for three days, on the third, i took it out and scrubbed them with a wire bursh and then put them back in the vinegar.(I emptied out the nasty vinegar and put in new vinegar.) The fourth i took them out and they are as good as new.

However, I would like to know how this chemical reaction works.
