Things You'll Need
Instructions
Dampen a clean cotton cloth with a small amount of water. A little bit of water is necessary to clean Gamecube discs, but too much can cause damage.
Hold the disc by its edges, with the game label facing your palm. Start in the center of the disc with the cloth; gently work your way outward in a straight line (do not swirl or use a circular motion).
Continue working your way around the disc, each time starting in the center and moving outward. Repeat the procedure, if needed, to optimally clean the disc.
