High-pile, 100% microfiber collects and holds dust and dirt mechanically and electrostatically for superior dusting results. Dense ultra-fine quality fiber removes more dust, dirt and bacteria, while advanced hook-and-loop backing holds-up under harsh laundering conditions and attaches pads more securely. Durable pad construction is third party tested for toughness and withstands more than 300 launderings, and the double finished edges retain pad shape.
