❑ 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.
❑ Do not use solvents such as benzine, thinner, commercially available
cleaners or anti-static spray, as they may damage to the disc.
