E-Cloths are made of millions of tiny fibers that pick up dirt which normal cloths just leave behind. When we say tiny, we mean each fiber is about 1/200th the width of a human hair. These tiny fibers attract moisture and oil, and lift and trap dirt, grease, grime and bacteria, leaving your surface clean and polished with no chemical residue left behind. This process is healthier with no chemicals used. There is no chance for potentially harmful fumes and residue. This is important to children, as well as allergy and asthma sufferers. Save money by reducing the use of paper towels and chemicals. E-Cloths come with a 300 machine wash guarantee giving you years of cleaning performance and savings.
