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. Common cotton cloths push dust and dirt around. E-cloth's special fabrication removes unsightly, unhealthy dust and pollen throughout the home and workplace. Importantly, it does so without use of applied or embedded chemicals. Lint-free and safe even on delicate surfaces due to the soft, non-abrasive fibers. (Not for use on electronic screens or delicate lenses.) Save money by cleaning without chemicals or paper towels. Machine washable; E-cloths can be used over and over again. This set includes two dusting cloths; each cloth measures 12.5"x12.5". E-cloth performance is guaranteed for 300 machine washings.
