What is the best way to clean video games

I assume you have a current game system, like a Wii, PS3, or Xbox 360. If you have one of those, and mean cleaning a disc, than the best way to clean the disc would be to either use canned air to blow air on the disc or to use a napkin/paper towel to wipe off dust from the disc. Do not, however, use water on the disc. That would possibly ruin the disc.
