If you want a CD, DVD cleaning system free of chemicals, you'll love our Phoenix Optical Cloth. Microfiber is a man-made product that combines two basic fibers, Polyester and Polyamide, producing fibers with a thickness less than a human hair that have been split 16 times into a "V" shape. The surface area of the cloth is increased by over 15 times, creating millions of crevices which trap and hold debris, making this cloth one of the most absorbent materials on earth. And it's washable by hand or machine. Air dry only. Keep your discs clean with a quick wipe and never have to worry about disc repair. In light blue only - 8 x 8 inches in a jewel case for neat and convenient storage.
