Walmart carries a microfiber towel listed for use with Rinseless / waterless car washes. They are quite nice, thick and plush, reasonably priced - big plus, just pick ‘em up at your local Walmart, always in stock. Here they're used for ONR type washes. WM also has some very nice drying towels as well, though I'm tempted give Griots PFM drying towels a try.
