It has been successfully reduced to the risk of friction scratches caused by friction when you wipe it up. If the bristles are short, they are easy to get scratched when wiping up, and if the pile is too long, it will leave a few spots like water droplets and other wiping them off again. We pay close attention to the weaving process not too hard or too soft as general tight and tight fabrics can increase the coefficient of friction and cause scratches. Experience our fully original EK Microfiber Cloth which is a result of instant tangling in waste and instantly absorbs a lot of moisture and reduces the coefficient of friction that causes scratches to the extremes. Use it with EK - ZERO for a better effect.
