I also do a combo of keeping a towel in my pocket, microfiber, and keeping others in the bag. clipped is a cotten towel for mud and debris. Best set up, keeps the hand/pocket towel relatively clean and dry longer. Only use it right before throwing. But I also rarely set my bag on the ground, it's always on my stool, so my towel doesn't drag
To clean a microfiber I usually get them cold...like in the freezer. Seems to lose some of its "grip" when really cold. Otherwise, a few hand washes usually work too.
