Get some good silver polish and your good to go. Or you could use 000 or 0000 steel wool and it will look like a million bucks. also if I had one I would cover it after it's shined up with either a clear shrink wrap or packing tape. That will keep it from oxidizing and getting dull. If your careful you can apply the packing tape without any wrinkles, then just trim around the switch and wheel with an exacto knife or razor blade. Either way will wear like iron.
