I just recently bought a 2018 YZ125 and it has about 5 hours on it. I was cleaning it today and I noticed a lot of spotted dirt stains on most of the aluminum parts including the frame and engine. I️ scrubbed it with a green scotch Brite pad and it came off but the hard to reach places (which is most of it) I cant get to and the power washer did little to help. Does anyone know of any cleaning products or anything else that could soak on there and make it so I can power wash it off?
