I have recently fit new c&s to my bike. Only problem is, my back wheel is now covered in really sticky chain grease! I have tried normal soap/detergent and it won't come off! Can anyone suggest a de-greaser (UK available product) that won't harm the finish on my wheels. I have looked at GUNK, but it say's on the can that it may harm paintwork. My bike is my pride and it is in very good condition for it's age. I don't want to spoil it....
