So, were you halted from playing your favorite game or halted from being able to watch your favorite movie because of a scratch you couldn’t get rid of? Well, try this technique. It may cause damage to your disk, so be careful. (I figured out this technique by myself after numerous tries and long research).
First, take a disk and place it on a table, so the shiny end is facing up. Then, take some peanut butter, and smear it (with your finger) completely over the disk. Then, take some toothpaste and smear it with your finger over the peanut butter.
Then, put the disk in a small container and put some Diet Coke on the disk, which is supposed to be facing up, (the shiny object facing up). Wait 3 minutes, and put a little bit of Baking Soda in the Coke. Close the cap on the container and shake it. Set it back down and wait 15 minutes.
After 15 minutes, take the cap off and carefully take the disk out. Wipe the disk down and wait until it dries. Then, your disk should be clean of any dirt and MINOR scratches. In rare occasions, the disk may be in worse condition.
I have heard this method from a YouTube video by Household Hacker (username).
METHOD 2 (Recommended for people that don’t want to risk their DVD or CD)
Put toothpaste on the DVD or CD (non-glittery kind).
Next, put the toothpaste (should be smeared on disk), under running hot water and shake it a little. After rinsing it about 20 seconds, stop putting it under the hot water. (WARNING: Do not allow the water to be hot enough to see mist coming from your disk. This WILL damage your disk.)
After this, completely wipe down the disk with cloth or a paper towel.
Then, the disk should not have any dirt and most MINOR scratches should be gone. (This method does not work as effective as method 1).
WHY TOOTHPASTE WORKS:
Toothpaste (non-glittery substance toothpaste) can clear away minor scratches and dirt because it contains a substance called fluoride, which performs a chemical reaction with peanut butter and other substances such as hot water, and then attacks the dirt and scratches from the DVD or CD.

PLEASE NOTE: I have tried this myself and it worked. For expensive games, I truly would recommend Method 2 because it doesn’t risk your game or movie or CD as much as method 1, even though that method is much better affected. I AM NOT RESPONSIBLE FOR ANY ADDITIONAL SCRATCHES OR DIRT THAT MAY HAVE OCCURED DURING THE CLEANING PROCESS.
