I've been using a couple of the Griot's PFM Terry Weave Towel (not the "drying" towel, just the PFM towel) for about a year now. I've mainly used them with spray waxes, but they are said to good for glass, wax removal, etc. also. They are very nice towels and are more dense/heavy than your standard micro fiber towels. My only caution is that they seem to snag very easily, especially when wiping near deck lid and fender emblems. I snagged both of mine very quickly after purchasing. This has not seemed to hurt the performance of the towel in any way, but just a word of caution if this is something that would bother you be very very careful when using them around emblems and moldings they could snag on!
