How do I clean and maintain my CDs to ensure longevity?

To clean and maintain CDs, use a soft, lint-free cloth to gently wipe the surface in a straight line from the center to the edge. Avoid using circular motions or abrasive materials that could scratch the disc. Store CDs in their cases when not in use, away from direct sunlight and extreme temperatures. Handle CDs by the edges to prevent fingerprints and smudges.
