http://www.shamwow.com/Shamwow! cloths wash, dry and polish any surface. They are like a towel, chamois and sponge all in one--except they're extremely absorbent and can be used over and over. Shamwow! towels are machine washable and bleachable, will not scratch surfaces, and will last for more than 10 years!
