Our microfiber dust mops are especially effective cleaning tools because their fibers are positively charged. This built-in positive charge is a useful byproduct of the manufacturing process. Dust is negatively charged, so it will be attracted to our microfiber mops like a magnet. These microfiber mops can be laundered up to 500 times. This far exceeds the 55-100 times that regular mops can be machine washed. In one year a hotel could see a 60% reduction in mop costs alone. Our canvas-backed dust mops are more secure than Velcro® alternatives, and can be used for larger, heavy-duty dusting jobs (up-to 60 inches wide).
