I will show you how to clean a disk. This is another methed that I use.
Step 1: The Peanut Butter
First get out your peanut butter and a butter knife.
Step 2: Smear the Peanut Butter
Next smear your peanut butter all over the disk and then you should wait about five minutes.
Step 3: Whipe It Off
Last you need to whipe off ALL of the peanut butter with a paper towel. Make sure that all the peanut butter is off of the disk.
