I recently bought a Yamaha Absolute Maple kit and I absolutely adore it. It has some minor blemishes, but I am fully attached to making it look and sound as good as it can possibly can. The biggest problem that needs solving (if possible) is cleaning up the badges on the kit. Specifically the badge on top of the kick. I didn't take a good picture of it but you can see the style from the posted pictures. There seems to be a brown-ish rust that has set in. I have heard about cleaning this with Coca-Cold and aluminum foil, but I worry that will damage the metal (gold colored). Does anybody have any suggestions about what to use to carefully clean this or should I just leave it alone?
