I thoroughly clean out my stuff after using them, so I don't label them per product or top and bottom since they are, for lack of a better term, "reset" after washing them (for microfiber, I use cold water, some Woolite, and a tiny splash of bleach, and let them soak). I do have one Adam's towel that has been used a lot more than the others, it's visibly worn compared to the rest so it's easy to distinguish, and I only use that towel for door jambs, wheels, etc. I make sure all of my towels, pads, etc are completely dry before storing them back in a bag or the bucket
