• | Handle your CDs carefully. Handle CDs by touching only the outer edge and the edge of the hole in the center of the CD. Avoid toughing the signal surface of the CD (the glossy, non printed "silver" side) because thick fingerprints and scratches will interrupt the readout.

• | Store your CDs in their original cases or other protective cases. This helps to keep the CDs away from direct sunlight, dirt, dust, and debris.

• | Do not attach a label or tape to a CD.

• | Always check both sides of the CD for scratches and signs of wear. Avoid using scratched or damaged CDs.

• | Never mark the outside rim of a CD with a marker.

• | Make sure to clean your CDs periodically.

### Cleaning a Compact Disc

If the surface of a CD is dirty or has fingerprints on it, clean the CD with a clean, damp, soft, lint-free cloth and a mild neutral detergent solution. Wipe the CD in a straight line from the center hole outward toward the edge. Avoid using cleaning solutions which may damage the CD like chemical cleaning cloths, benzene, thinner, or spray. While cleaning the CD, avoid touching the signal surface of the CD because thick fingerprints and scratches will interrupt the readout. Scratches on the label side will also affect the sound.
