This video shows you how to clean a CD or DVD easily.First of all, you need toothpaste. Apply a thin layer of paste to the whole surface of the disk and spread it evenly. Let it dry for about 5 minutes. After the 5 minutes have past, clean the whole disk at a sink, and make sure you get all the paste off. Wipe off the disk with a towel, but be careful not to make any scratches while doing so. You could try wiping from the middle of the disk to the exterior. The disk must be dry before using it again.
