Jewelers rouge and a buffing wheel will do it. If you don't coat it with something like clear varnish it won't last very long.

Brasso actually does work...not like everyone canget their hands on jewelers rough...

You can pollich the screws and then spray them with a clear varnish that can be found at any hobby store in the paint or craft department, or you can paint them with clear nail pollish.

Best of luck.

Brasso

installing new screws are much less work or brasso and some elbow grease will work.

"brasso" and lots of rubbing
