Wayne, If you don't mind elbow grease then use that old military standby, Brasso. Or dip it in some CLR. I use both methods, I dip in CLR for no more than 30 seconds to loosen up any dirt and grime and then use the Brasso with a soft toothbrush and soft cloth to clean it completely. I beleive that a good clear lacquer sprayed evenly would work good.
