Proper Care of CDs: Overview
^ Never handle a CD by the top or bottom; only touch the edges.^ Do not affix paper or tape, and avoid scratching either side of the disc.
^ The disc revolves at high speed within the CD changer, so defective (cracked or badly bent) discs should not be used.
^ Dust and/or finger smudges will have no direct effect on the signal recorded on the disc, but dirt can decrease the amount of light reflected from the recorded surface, thus affecting quality. If the disc should become soiled, gently wipe the surface with a soft lint-free cloth, wiping from the center of the disc to the edge.
^ Do not use record cleaning sprays or anti-static agents. Such volatile chemicals as benzene and thinner can damage the surface of the disc and should not be used.
^ As with traditional audio records, compact discs are made of plastic. To avoid warping, keep the discs in their cases and do not store them in places exposed to direct sunlight.
