How to Repair GameCube Games
Clean the disk using a lens wipe. Do not make circular motions, as this may damage the disk. Instead, wipe gently from the center out to the edge.
Apply toothpaste, Armor All or wax to the disk. Wipe in the same fashion as you did in the above step, from the center out.
Wash off the toothpaste, Armor All or wax with warm water.
Dry the disk using a soft cloth. Wipe gently from the center out to the edge.
