CD/DVD Scratch Repair
Here are some basic facts about scratches on CD and DVD discs.
- The data is stored just under the label. Scratches on the label side are irreparable. Fortunately, most scratches happen on the shiny side, and there’s a millimeter of clear plastic between the surface and the data. These scratches can often be fixed.
- The data is arranged in concentric circles on the disc. Scratches that follow this pattern (often produced by defective CD or DVD players) are the worst kind. Perpendicular scratches are often harmless due to the redundant data stored on a CD or DVD.
- You should start with a clean CD before attempting to remove scratches. Use an electronics cleaner, isopropyl alcohol, or distilled water and a paper towel. Avoid following a circular pattern when you clean.
- Make sure your CD repair device is clean as well. One large particle in the wrong place can compound the damage rather than fixing it.
Household Solutions
A jewelry polishing cloth and brass cleaner can be used to take care of minor scratches. Toothpaste can also be used. Carefully squeeze some cleaner on the scratched dvd. Spread the cleaner from the center to the outside rim. Rinse off with a stream of cold good quality water. Dry with the polishing cloth and let it sit over night.
- Rub from the center out, not around the circle.
- Avoid following a circular pattern when you clean

Software Solutions
Software cannot ever read data from a CD that is too badly scratched. For the most part, what software can do is, to put it simply, be more "stubborn" as opposed to the Windows operating system in trying to read a disc before giving up. It is theoretically possible for software to apply fuzzy logic to skip past certain areas and try to reconstruct, however, in practice it appears that the available tools mostly apply focusing in reread attempts, or just skipping past a bad spot and filling in with null data. Some tools may be useful, while others offer little more than what you can do with Windows yourself.
