CD Care & Maintenance

Handling CDs

Hold a CD by its edges. Avoid touching the recorded 

side of the disc. To remove a CD from its storage case, 

press down on the center retention mechanism of the 

case and lift the disc out by its edges.

Cleaning CDs

Use a dry, soft cloth to wipe off any fingerprints and 

dust from the playing surface of the disc. Wipe in a 

straight line radially from the center to the outside 

edge of the disc. Small dust particles and light stains 

will not affect playback quality.

 • Never use chemicals such as record sprays, anti-

static sprays, benzene, or thinners to clean your 

CDs.

 • To reduce the risk of scratches, always put CDs 

back in their case after use.

 • Do not subject CDs to prolonged exposure to direct 

sunlight, high humidity, or high temperatures.

 • Do not place stickers or labels on either side of the 

CD.

Cleaning the Lens of the CD Player

A dirty lens can cause CD playback to skip. If the lens 

is very dirty, the CD may not work at all. Unplug the 

power supply, open the CD door, and clean the lens as 

follows:

 • For Dust or Dry Particles—use a camera lens brush/

blower to blow on the lens a few times. Then, wipe 

the lens gently with the brush, and blow on the lens 

once more. 

 • For Fingerprints—use a dry cotton swab to gently 

wipe the lens in a straight line radially from the 

center to the outside edge.
