These stains are from improper washing. The shampoo from many car wash' is harsh for the materials, as it is (most of the time) a generic cleaner. this guys bike, they washed it with a veru harsh cleaner when the engine was hot. is there any possibility to polish it with a mini polisher or what else can we do here?i think this material is anodized aluminum or maybe magnesium. we are talking about a cbr600 here
