On Cleaning CD-ROMs and DVD-ROMs
❑ Fingerprints and dust on the surface of a disc may cause read errors.
Proper care of the disc is essential to maintain its reliability. Do not
use solvents such as benzine, thinner, commercially available cleaners
or anti-static spray, as they may cause damage to the disc.
❑ For normal cleaning, hold the disc by its edge and use a soft cloth to
wipe the surface from the center out.
❑ If the disc is badly soiled, moisten a soft cloth with water, wring it out
well, and use it to wipe the surface of the disc from the center out.
Wipe off any remaining moisture with a dry soft cloth.
