Smooth texture of the glass cloth easily releases particles with rinsing. This cloth also reduces the amount of chemicals needed for cleaning. Studies by the EPA have found that microfiber cloths eliminated 94% of bacteria from surfaces (compared to 68% reduction by regular mops.) Using the color coding system eliminates any guesswork from what product should be used when. Which means microfiber that is used to clean guestroom toilets will never be used to clean vanities. Our microfiber cloths are lint-free and can be laundered up to 500 times.
