Xbox 360 discs can be scratched easily if not treated properly. Here are some tips to help fix a scratched Xbox 360 disk:

  1. Clean the disk with a mild soap and water. This will remove any built-up dust and dirt on the disk.
  2. Use a dry cloth to clean the disk surface. Be sure to avoid getting any liquid on the disk surface, as this could cause it to become dirty and difficult to read.
  3. Place the disk in a cool, dry place for 30 minutes or until it has dried completely.
  4. Place the disk back into its original packaging and store in a cool, dark place for up to two weeks so that it can harden slightly and prevent further scratches from happening.
