If you have kids, chances are you have scratched and marred cd's and dvd's lying around. Here is the best way to remove the scratches and restore the disc to a playable condition.
Wrap a 100% cotton rag around your index finger and apply a small amount of Brasso polishing compound to the rag.
Polish the scratched area in a circular motion applying a small to medium amount of pressure.
Using a clean part of the rag, wipe off all traces of the brasso polishing compound.
Try playing the CD or DVD disc in its appropriate player.
