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, DVD, and Combination Drives
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, clean the discs.
1.
Hold the disc by its outer edge. You can also touch the inside edge of the center hole.
2.
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.
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.
NOTICE:
To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only use products specifically designed for
cleaning computer displays.
NOTICE:
Always use compressed air to clean the lens in the drive. Never touch the lens.
NOTICE:
To avoid damaging the surface, do not wipe in a circular motion around the disc.
