Yeah, I should have been a bit more descriptive. The method I was taught is to clamp a small piece of regular paper (notebook paper, printer paper, etc) between the contacts and pull on it. If you clamp too tight on the paper it will tear, but at just the right pressure you can pull the paper through and see the discoloration as the oxidation and any other build-up on the contacts wipes off.
I have heard a pencil eraser can have similar results.
