Floppy Drive
Use only a commercially available cleaning kit to clean your floppy drive. Such kits contain pretreated floppy
disks to remove contaminants that accumulate during normal operation.
CD, CD-RW, and DVD Drives
NOTICE: Always use compressed air to clean the lens in the drive. Never touch the lens.
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, clean the discs.
Hold the disc by its outer edge. You can also touch the inside edge of the center hole. 1.
NOTICE: To avoid damaging the surface, do not wipe in a circular motion around the disc.
With a soft, dry, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight
line from the center to the outer edge. 2.
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.
