my father recently picked up a honda shadow 750, red with a lot of chrome. i cleaned the bike for him, and made it look absolutely gorgeous, unfortunately, my lack of bike knowledge has left him with mud on his tires. its dried and very difficult to scrub off, and since im not sure what to put on bike tires to remove it, i figured i would come to you guys for some expert advice. its mainly in the tread, and im not worried about the dirt along the road touching sections. that should wear off rather quickly.
can get pictures if you need them. thanks!
