These are professional or commercial grade cleaning pads. 80/20 Microfiber Polyester & Polyamide Blend. The polyester provides the durability which is why these will last hundreds of washes and dry quickly and the polyamide increases the absorbance. These two combine in harmony or are a strategic blend of fabrics. Traps and holds dust, dirt, scum, grime and bacteria from unwanted areas and is obviously re-washable!
