This video shows you how to clean a compact disk using peroxide and toothpaste as the cleaning agents.First of all, put the disk in a mixture of water and a bit of peroxide and let it stay there for about 5 minutes. Then, you must take out the disk and apply a thin layer of toothpaste on the whole disk's surface. Let it sit like that for another 3-5 minutes. After that, clean the disk with water. Use it only when it is dry. If this method does not work, then you should either take the disk to a professional disk cleaner or buy a new disk.
