I've been using what I think are quality MF's (75/25) and I notice micromaring from them if I rub just a little to firm. Is this normal? Do all MF's act like this? I've been using them to remove polish and wax. With light pressure they seem fine, but I have to be very careful. I've gone back to using jersy knit cotton towels to remove most of the wax first, as they will not scratch then the remainder with MF. I'm curious if anyone else is having this problem.
