I had my V Rod Muscle for 2 days when I picked my daughter from school. Unfortunately she was wearing soft souled boots that folded over the rear pegs and both heal and toe on the left and right side melted to the pipes. one side was easy to wipe off while hot but by the time I got to the other side the pipes were cooled off and appeared to be permanitely stained. I tried every type of cleaner available at my local Harley dealer and Kragen auto parts, I even tried getting the pipes hot again but still no success. I almost gave up but a neighbor told to try hand cleaner (without pumice) he said he had used it on everything from chrome to polished aluminum and even painted surfaces and it never/ever damaged the surface. well lo and behold he was right it wiped off that burnt rubber with ease and never left a mark!
