Well, it depends a on how bad a shape it's in. If it's got most of its plating left, and you want to just polish that up, I'd use toothpaste (just rub on with your fingers, then buff off with a cloth). If plating is nearly gone, or totally gone, you can go the route of just stripping off whatever's there, and getting down to the base metals (usually copper for the head and brass for the baseplate and handle...but it varies from model to model). Check out the BOTOC thread I mentioned for some examples of stripped down, and polished up New's.
