swab is not left on the rollers.

Floppy Drive

NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally misalign the
heads, which prevents 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

Hold the disc by its outer edge. It is okay to touch the inside edge of the center hole.
1
NOTICE: To prevent 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
2
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.
