I was wondering what you guy's and gal's do . I have 10 MF's I use mostly to buff off polish and wax that I've applied with my PC. Is it okay to use the same one for both buffing off polish and wax? Or should I use one MF for polish and one for wax? I was even thinking of labeling them with a "P" or a "W" on the corner. Do you wash them after each use or do you use them multiple times? What are your thoughts on the subject?
