152 Appendix
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning
the discs.
Hold the disc by its outer edge. You can also touch the inside edge of the center hole.
NOTICE: To avoid damaging the surface, do not wipe in a circular motion around the disc.
With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line
from the center to the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase
commercial products that clean discs and provide some protection from dust, fingerprints, and
scratches. Cleaning products for CDs are also safe to use on DVDs.
