The E-Cloth high performance dusting cloth has dry dusting and damp cleaning down. Used dry, the cloths 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. Dry or damp, the E-Cloth high performance dusting cloth is your secret weapon for a simpler, swifter, savvier clean.
