Been using them for a good while now, for that . I cut an old sock, opened it up length wise and use it on the back side of the pad to keep my hand on it better.
I also cut up the pad, after the polishing thing uses the 'sponge' side up and use the 'grit' side to smooth out a thumb if I feel something I don't like. I have several in my bag for leagues, great to just lightly rub to get any glue residue off as well.
I'm cheap ! I'll use a pad for many things before it really goes into the trash.
