Wipe the keyboard, computer, and plastic part of the monitor with a soft cleaning cloth moistened with water.
Do not soak the cloth or let water drip inside your computer or keyboard.
Mouse
If your screen cursor skips or moves abnormally, clean the mouse. To clean a non-optical mouse:
1.
Turn the retainer ring on the underside of your mouse counterclockwise, and then remove the ball.
2.
Wipe the ball with a clean, lint-free cloth.
3.
Blow carefully into the ball cage to dislodge dust and lint.
4.
If the rollers inside the ball cage are dirty, clean the rollers with a cotton swab moistened lightly with isopropyl alcohol.
5.
Recenter the rollers in their channels if they are misaligned. Ensure that fluff from the swab is not left on the rollers.
6.
Replace the ball and retainer ring, and turn the retainer ring clockwise until it clicks into place.
Floppy Drive
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
If you notice problems, such as skipping, with the playback quality of your discs, try cleaning 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, 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.
