In order to remove scratches from a CD, wash the CD well, and then use baking soda toothpaste to gently buff scratches off the surface of the CD. Use a paste toothpaste rather than a gel to ensure that the paste removes as much of the scratch as possible.
Scratches on a CD usually cause it to skip, but some players are so sensitive that they do not allow a scratched CD to play at all.
Step 1: Clean the CD
Use warm water and a drop or two of dish soap. Gently rinse the soapy water over the CD and rinse well with fresh water. Shake the excess water off the CD and allow it to air dry.
Step 2: Test the CD
Sometimes a cleaning is all the CD needs in order to play properly, but often there are other steps necessary.
Step 3: Find the scratch
Tilt the CD in strong light to find all the scratches. Make note of where the scratches are in order to focus on those areas.
Step 4: Remove the scratch
Use a baking soda toothpaste to remove the scratch. The toothpaste must be a paste rather than a gel in order to work properly. Dab a small amount onto a soft cloth and rub the toothpaste gently onto the scratch working from the center of the CD toward the edge only. Use gently pressure to avoid causing deeper scratches.
Step 5: Wash the CD
Wash the CD again and be sure to remove all traces of toothpaste. Allow to air dry again.
Step 6: Test the CD again
If the scratch is still present, repeat the process as necessary until all scratches are removed.
