Abstract
A pre-moistened towelette wipes a compact disc clean without leaving a visible residue thereon. An ultra-pure tissue, free of binders, fillers and dyes, is permeated with a liquid cleaning preparation comprised of a highly concentrated solution of ultra-pure alcohol, a non-ionic, ultra-pure surfactant, and ultra-pure water.
