One simple way to fix a scratched CD is to smudge toothpaste on the scratches, then gently polish the CD using a soft cleaning cloth. After a few minutes, wipe the excess toothpaste away with another cleaning cloth, and apply a small amount of carnauba wax to the CD.
- Apply the toothpaste
Apply a pea-sized amount of regular white toothpaste on the corner of a cleaning cloth or onto a cotton ball. Dab the toothpaste onto the CD, making sure to wipe from the center to the outer edge.
- Polish the scratches away
Use either circular motions or polish in straight lines from the center of the CD to the outer edge, but try to stick to one polishing motion. Polish the CD using an even amount of pressure. Check your progress periodically by wiping the toothpaste off with the clean part of your cleaning cloth and washing the CD under lukewarm water. Apply a dab of toothpaste and polish the CD again if any scratches remain.
- Apply carnauba wax to protect the CD
After the scratches are completely gone, wipe the back of the CD dry with a clean microfiber cloth. Apply a dab of carnauba wax to a cotton ball, then gently wipe the wax onto the CD. Use the other side of the microfiber cloth to wipe off the excess wax.
