Cleaning Your Computer

5 Recenter the rollers in their channels, as needed. Ensure that fluff from 

the swab is not left on the rollers.

6 Replace the ball and retainer ring, and then turn the retainer ring clockwise 

until it clicks into place.

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.
