I was curious about how this works. Turns out the molasses mix makes an acid, so basically its similar in principle to most other rust removers like naval jelly and vinegar. I'm assuming that its more gentle, or something in the mix makes it work better since Glen is vouching for it, and I haven't seen him give bad advice.

Something I've wanted to try is using electrolysis for rust removal. Looks dead simple and is supposed to give great results. Unfortunately (or fortunately, I suppose) I haven't had anything rusty enough to try it on. If anyone wants to take a shot, heres a tutorial...
