lick it.

dont lick it run it ondar water

and dry it with a towel or your shirt.

P.S. it works for all of my games

u are a ****** retard for asking me this lol just asked for it to be cleanaed at the game
store *****

all you need is tooth paste and 2 kleenaxs.
make a cirle of tooth paste and rub it with a kleenax . then run the disk under water and
use the last kleenax to wipe th toothpaste off.

if it doesnt work then take it back to the store and have tham clean it.
