Another method is to use Nevr-Dull. It's a type of wadding infused with polish. Works great on cars and most metal parts, including guitar hardware. It's sort of like cotton candy. You pull a little out of the can and rub stuff with it. I've used it on frets, after masking, and obtained great results. And it's very controllable.
