In order to remove the scratches from a CD with toothpaste, you will need: regular toothpaste, a towel or washcloth, and water. While holding your CD in one hand, being careful to avoid touching the center, coat the CD with toothpaste. You should try to cover one small area at a time, with a thin layer of toothpaste. Apply the toothpaste in a circular motion. After the entire playing area is covered with toothpaste, set it aside. Allow the CD to dry for 5 minutes. After it has dried, rinse it. Hold it under running water and gently rinse it. When all of the toothpaste has been washed away, dry it with a towel. Wipe it from the inside to outside. Do not dry it in a circular motion. It must be wiped from the inside to the outside.
