back when i first got into detailing i wanted to know how to maintain my car w/out washing it since dust settled so easy. after searching i found out about qd's and the california duster. i think like tech said anything can cause scratches but i dont think the duster is the go to item for a professional detailer. hopefully one of them will chime in
