Remove dust from any hard, dry surface with ease. E-Cloth dusting cloths have millions of tiny fibers with a natural positive static charge that attracts and holds dust and allergens into its soft texturing. A warm rinse is often enough in day to day use. Machine wash regularly at medium temperature, using a little detergent and rinse well. If too much detergent is used, cleaning performance may be reduced, in which case, re-wash without any detergent.
