Instructions
Use plain water to dampen the cloth. Make sure that the cloth is clean and that it is not an abrasive material like a paper towel or tissue.
Wipe the bottom of the disc with the damp cloth in straight motions. Wipe from the inside of the disc straight out to the outer edge. Do not wipe in circular motions.
Let the disc try for a few minutes before you insert it into the Wii. Once the disc has dried, try playing it again to see if it works.
