How to Clean a CD

Introduction

Dirty CDs can skip, freeze, or fail to play altogether. Cleaning a CD properly helps maintain sound or video quality and prevents unnecessary wear on your player. With the right technique, you can restore your disc without causing scratches.

What You'll Need

• Microfiber cloth

• Distilled water

• Isopropyl alcohol (optional)

• Mild dish soap (optional)

• Soft-bristled brush (optional)

Steps

Hold the CD by the edges to avoid adding more fingerprints.
Use a microfiber cloth to gently wipe from the center of the disc outward in straight lines.
If debris remains, lightly dampen the cloth with distilled water and wipe again using the same center-to-edge motion.
For tougher residue, mix equal parts water and isopropyl alcohol, apply to the cloth, and wipe the disc carefully.
Allow the CD to air-dry completely before playing or storing it.
If dirt is trapped in the center ring or edges, use a soft-bristled brush to remove it gently.

Alternative Methods

• Rinse the disc with lukewarm water and mild dish soap, then wipe from center to edge.

• Use a commercial CD cleaning solution designed for optical media.

• Use a CD repair kit for minor scratches that affect playback.

What NOT to Do

• Do NOT wipe in circular motions—this can cause playback-impacting scratches.

• Do NOT use abrasive cleaners like glass cleaner, vinegar, or acetone.

• Do NOT use paper towels, tissues, or clothing that may scratch the surface.

FAQs

Can I fix scratches on a CD?

Minor scratches can sometimes be reduced using a CD repair kit or professional resurfacing. Deep scratches may not be repairable.

Is it safe to use alcohol on a CD?

Yes—use isopropyl alcohol mixed with water. Avoid harsh solvents that can damage the disc’s protective layer.

Why should I wipe from the center outward?

Straight strokes help prevent damage along the data track, which spirals around the disc. Circular wiping can create scratches that follow the data path and affect playback.
