Scratches can not be cleaned they are not dirt. If you try many of the home remedies you will find that they do not work. Often having the disc cleaned and polished in a professional machine does not restore a unworkable disc back into a trouble free condition
use rubbing achohol and clean the scratches
When I need to clean a disk, I grab some shampoo and spread it over the disk, then I rinse it off. Don't scrub it. Then I dry it off with a tissue. I also do this for scratched games. It doesn't actually fix the scratches, but it somehow helps and I'm able to play the game again.
take it to checkouts or a pawn shop to be cleaned
Most are not dirty they are scratched and you can not clean off scratches they can sometimes be polished off professionally.
Rub toothpaste on it with a cotton ball then clean off with another clean cotton ball then dry it off
If the shopkeeper is kind enough, bring the disk back to him and ask him to repair it.
Get a slightly wet tissue and clean the bottom side of the disk by starting in the middle and carefully moving the tissue from the inside straight to the outside edge of the disk. Keep doing this till you go all around the disk. You will then need to either wait, or you dry the disk by using this same method but using a dry tissue this time.
Use toothpaste. NOT GEL! gently rub on disk and then take a wet towel and wash it off.
Toothpaste has a fine grit that will actually scratch your disk even more. I've found that the best way to fix small scratches is with peanut butter. You use a small amount of creamy (not chunky-you don't want chunks of peanuts) peanut butter, wiping it on the disk in one direction. Then, you use a clean rag to wipe the peanut butter off, in the opposite direction. It works quite well.
You shouldn't call the company because have you done any thing that could have maybe scartched the bottom of the disk? If so some stores have a disk cleaner that can clean the scratches off your disk. But if all your games aren't working you should call the company or ask a friend for help.
Your disk could be scratched, look at the bottom of the disk and look for scratches. There is a product you can buy that removes scratches without harming the disk, thus fixing your problem.
