8″ x 15″ Microfiber Mop covers are a blend of microscopic polyester and polyamide fibers which are split in such a way as to create microscopic hooks which act as claws that scrape up and hold dust, dirt and grim. They are 1/16 the thickness of a human hair.
Microfiber absorbs 7-10 times its weight in water or other fluides. The Microfiber grooves act like capillary tubes in soaking up even the biggest spills.
