I recently tried the Hot Rims polish on my motorcycle - it took the blemished off, cleaned off the residue inside the edges of the exhaust pipes. Brought the clutch and brake levers back to the original shine, and also the shift and brake pedals -
Over all very happy with the product. Note - you did have to watch the product close to the tires - it left a white smear mark there if not wiped off - it cleaned up wit tire cleaner very quickly - just a heads up.
I would recommend it to someone to use.
