This 16 inch x 24 inch, plush loop pile, 75% Polyester and 25% Polyamide blend cloth is the finest glass cleaning cloth we have ever found. The super absorbent properties of the 25% Polyamide and the scrubbing power of the short loop pile combine to make glass cleaning easy. Spray a small amount of glass cleaner onto the center two-thirds of the glass, use one side of the Micro-Maize to work the glass cleaner out to the edges, then turn the cloth over and burnish the glass crystal clear. When dirty, machine wash using the gentle cycle and warm water with detergent, no fabric softener or bleach and machine dry on low without dryer sheets. Do not wash with any cotton fabric as the lint will be trapped by the Microfiber. Each package contains 3 cloths.
