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 CD/DVD drive, and

follow the instructions that come with the compressed air. Never touch the lens in

the drive.

1

Hold the disc by its outer edge. You can also touch the inside edge of the

center hole.

NOTICE: To prevent damaging the surface, do not wipe in a circular motion around

the disc.

2

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.
