When CDs were first introduced, they were touted as being virtually indestructible. However, that notion has since been dispelled. While you can purchase commercial CD repair kits to mend these delicate items, there's actually a simpler solution available. Grab that tube of toothpaste and let's dive in.
Steps
Getting Started

Inspect both sides for damage. CDs store data just beneath the label, so a scratch that penetrates the label can render the CD useless. Thankfully, scratches are typically more prevalent on the reflective side, which is where toothpaste comes into play. The CD reader's laser needs a smooth, even surface to function properly, and toothpaste can help smooth out minor scratches and scuff marks.

Prep the CD with a Damp Cloth

Choose the Right Toothpaste
Buffing the CD with Toothpaste

Apply Toothpaste to Cloth

Polish the Scratched Area

Rinse away the toothpaste residue from the CD surface by letting running water flow over it. Then, carefully wipe it with a clean cloth, ensuring you follow the direction of its grooves.

Pat the CD dry with caution, as a dry CD is susceptible to scratches. Use a lint-free cloth to absorb most of the moisture, starting from the center and moving outward in straight lines. Allow it to air dry completely or gently rub it with a dry section of the cloth.

If the CD remains non-functional even after drying, consider using stronger cleaning agents. Test it thoroughly before proceeding. You may use polishes designed for silver, plastic, or furniture, avoiding those with kerosene or petroleum derivatives that could harm the CD.
Helpful Tips:
- Avoid applying toothpaste near the central ring of the CD.
Important Warnings:
- It's advisable to refrain from using warm water, as it could lead to overheating of your CD player if you play the CD immediately after repair.
