Can you do anything to restore a scratched DVD or CD?

How to fix a scratched CD or DVD

This will only work if the disc is scratched and none of the foil is missing or flaked off. I have a music disc that was scratched beyond listening, I took some 2000 grit wet/dry sandpaper, rubbing compound, and micro glaze designed for cars. Using the 2000 grit sand paper wet sand the disc, start from the center and go in a straight and perpendicular line outwards slowly working your way all the way around the disc until you can no longer see any scratches other than the sand paper marks. Then repeat with rubbing compound until the sanding marks are no longer visible. Then use the microglaze and repeat. The disc should be shiny and play fine.

You can also buy repair kits at almost any electronics store and over the Internet.

They are relatively inexpensive, easy to use and yes, they do work.

I use them often to fix CD's that are damaged from bouncing around in my CD player in my car (works on DVD's and Roms also).

More info:

rub the scratch with a soft cloth with tooth paste on it. rub in the direction of the grooves.

They way that I repair scratched CD's is using a CD cleaner. You can buy them anywhere stores sell computers and things like that. The CD kit (that I have) basically cleans the disc all over leaving it spotless
