The difference between these towels and regular microfiber is a luxurious feel combined with a dense heft. I like the feel so much I'm reluctant to get them dirty with black chain wax residue. But the pleasure of their cleaning ability encourages me to trust they will wash clean. I started with wiping down my frame - so easy to get it spotless. The chain wipe was more effective than my paper towels and without the small pieces of paper to pick out of the links. I am pissed at Silca's easy ability to spoil me with their products. They make going back to standard items a serious burden. Thanks, I guess.
