I bought one of the Viking 100% cotton chenille wash mitts from Kragen a week or so back. Seems to do a great job, haven’t noticed any scratching. Did the burn test as well and it does leave a bit of something solid behind. I burned some cotton from a Q-tip and it left just a tiny amount of ash. I’ll use this till I find something I know is 100% pure, but as I mentioned it seems to be doing a good job in the meantime. Viking’s consumer info # is 1-800-325-3545 if someone feels motivated enough to investigate further.
