The MysticMaid microfiber cleaning cloth was developed for computer clean rooms. Its patented microscopic nylon/poly fibers are split many times to create literally millions of tiny hooks and channels that attract and hold all kinds of dirt, grime, grease and dust. MysticMaid is the gold standard of microfiber, giving much better results than other microfiber products. The MysticMaid cleaning cloth cleans any hard surface to a brilliant, streak-free shine. Windows, mirrors, countertops, furniture, tile, granite, even such cleaning challenges as stainless steel, fine crystal, jewelry and eyeglasses, all come spotlessly clean. Just wet the MysticMaid, wring it out and it's ready to use. Wipe the cloth over any hard surface and walk away. The remaining swipe marks and micro-beads of water disappear within 30 seconds. With the MysticMaid, you use no soaps, detergents, cleansers or chemicals whatsoever; just the MysticMaid cloth and water are all you need. And, it's economical; the MysticMaid cloth can be used over and over, year after year. Just get it wet and wring it out. To clean the MysticMaid cloth, simply machine wash in cold water and hang it up to dry. Up to 50-percent larger than other microfiber cloths, the MystiMaid microfiber cleaning cloth measures 19.75" x 13".
