Floppy Drive
NOTICE: Do not attempt to clean drive heads with a swab. The heads may become
misaligned and prevent the drive from operating.
Clean your floppy drive using a commercially available cleaning kit. These
kits contain pretreated floppy disks to remove contaminants that accumulate
during normal operation.
CDs and DVDs
NOTICE: Always use compressed air to clean the lens in the optical drive, and
follow the instructions that come with the compressed air. Never touch the lens in
the drive.
If you notice problems, such as skipping, with the playback quality of your
discs, 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 safe to use on DVDs.
