How to fix a Scratched CD/DVD

Sometimes ur CD/DVD may not work due to scratches. But it contains ur important data then what to do ? this situations comes many times. So here is the way to how to make them work for u. Try at ur own responsibility :-

Clean the disc. Even if a CD isn’t actually scratched or scuffed, dust, oil, and other surface contaminants can prevent it from playing properly. Thus cleaning the disc should always be your first move.
1. Run warm water over the damaged disc to remove dust.
2. If there is stubborn dirt or grease on the disc, gently rub it with your finger while you are washing it, and use a gentle detergent or liquid soap (with the water) or rubbing alcohol (in place of water). Any time you rub or wipe a CD, you should do so by starting at or near the center of the disc and rubbing straight outward toward the edge to prevent further scratching.
3. Shake the water off and let the disc air-dry (do not dry it with a towel or cloth, and don't sun-dry it either).
Try to play the disc. Many times a good cleaning is all that is needed. If, however, problems persist after cleaning, try to play the disc in a different CD player. Some players handle scratches better than others; computer CD drives tend to be best.

If this doesn’t work, try to polish the disc :

1. If you have a lightly scratched CD, you can use toothpaste. Just put some toothpaste on the scratch and stretch it out with your fingers.

2. BRASSO™ is a good way to re-surface the disc. Just throw some BRASSO on the disc and rub in circular motion the disc with cotton.

3. Put Car Wax or Vasoline on the cd and rub it in. Then wipe it off. Some web pages say that you must let it dry, but I washed it. and its supposed to fix the scratches... This trick also works on scratches on car windows, etc.
