I have fleece doublers, and fleece lined diapers (like Granny's Ark); as well as fleece covers; I use All Free and Clear; and if I have extra money, lol, I spluge on BioKleen. I haven't had ANY problems with repelling! I have heard that some have fuzzi bunz repelling problems with "free" and natural detergents.........
But as far as regular fleece, no problems here!
