The E-Cloth High Performance Dusting Cloth has dry dusting and damp cleaning down. Used dry, the cloth's extralong, extra-fine fibers attract and trap dust, pollen, pet hair and more from wood, glass, granite and leather. (Compare that to ordinary dusters that simply push around dust, leaving behind plenty of particles to irritate eyes and noses.) Dampened with water, the E-Cloth High Performance Dusting Cloth removes grease and grime from hard surfaces. Just fold and use as a multi-surfaced pad. Rinse between tasks and toss in the laundry - not a landfill - to refresh. Because unlike single-use dusters, this cloth is guaranteed to perform for 1 year or 100 washes. Dry or damp, the E-Cloth High Performance Dusting Cloth is your secret weapon for a simpler, swifter, savvier clean.
