I have a couple of those, that I ended up with from somewhere, and yes they work great. I go down to Wally World and buy flannel by the yard for about $4.I got these on Amazon a while back. Work awesome to take off the mother's billet. Put on some nitrile gloves and just use your fingers to rub the mother's around. It makes it go a LOT further as well since a towel/pad isn't soaking up the polish. Then buff off with the towels. I wash these in the machine with some dawn dish soap and then toss them in the dryer. Don't use dryer sheets or fabric softener when cleaning your towels as it'll streak and drive you crazy.
