Fix DVD scratches the simple way, with car wax.
Don’t throw away that scratched DVD (or CD or Wii disk) just because of a few scratches! You can use car wax to fill in scratches and make your disc playable once again.
First, clean the disk in warm water and let it dry. Then, fill the scratch with a tiny bit of car wax. Allow the wax to dry, and then use a clean cloth and buff from the center of the disc outward. Be sure to use a non-abrasive cloth (and not a paper towel).
Problem solved. Let the show (or music, or games) begin.
