Things You'll Need
Instructions
Clean the disc before anything else. Do this by running it under a gentle stream of lukewarm water from the tap. If the disc is extra dirty, use a soft, non-abrasive and lint-free cloth along with some mild detergent to clean the disc. Make sure you wipe in a straight line from the center outward. Dry the disc when finished using the lowest setting on your hair dryer and another soft, lint-free cloth. Try it out when it's completely dry. If it works, you don't need to repair it.
Check the disc for any top-layer scratches. The top layer of the disc is where all the data is stored. If this is damaged, you're out of luck and there's no chance of fixing your game disc, no matter how much your buff out the scratches. Determine whether you have any top-layer scratches by holding the disc up to the light. If you can see and holes or slivers of light shining through (they're easy to distinguish), you have top-layer damage.
Lay out a towel for your working surface and give the disc a quick dusting using a can of compressed air.
Put a small amount of metal polish onto a cloth and gently buff away the scratches on the disc. Be extremely gentle and work as softly as possible, moving in a circular motion. Pushing too hard will only scratch the disc further, causing more harm than good.
Rinse the disc under the tap using lukewarm water, and dry it using the lowest setting on your hair dryer. Make sure it's completely dry before moving onto the next step.
Put a small amount of polymer-based car polish on a cloth and spread it over the disc in a circular motion. Work as gently as you did when buffing the disc with metal polish, and make sure to spread the polish evenly.
Wait a few minutes for the polish to dry. Rinse it from the disc using lukewarm water from the tap and, once again, dry it using the lowest setting on your hair dryer. Make sure it's completely dry before putting it in any game console or computer.
