Saw some in Target today, they seemed pretty soft and apparently (per advertising) they get softer as you use them. I've seen people say these are the best for removing wax as they don't take too much off when you buff.
100% cotton towels such as those diapers from my understanding are still the best to use for a pure wax
I have some that I had bought years ago. They're great wrapped around the steamer when doing carpets...they really absorb stains!
