Moonshot, I will approach this from a different angle. There is a product called "Road Rub" that is used when boot soles melt onto chrome motorcycle pipes. Part of my nylon chin strap got on my hot pipes and left a melted black spot. I was able to get it off without damage to the chrome using Road Rub. Its a dry type of product in a stick that is really effective. Anything with an abrasive content will damage the chrome. I would suggest going to your local Harley dealer and picking up a stick. It's the only thing I use when stuff gets on my hot chrome pipes.
