how do i clean a scratched xbox 360 game at home?

i am from brazil i use toilet paper or my cotton shirt to clean a disk, but you can buy a disk cleaner.

you can try alot of old methods, like using toothpaste, using pledge, or galss repair, but the best thing you can do to fix it if the game is ringed, take it to game factor, game stop or anywhere that sells used games and see if they can use the machine in the back to remove it. they usually charge 3-4 dollars for this but it is the best way to remove the scratches. i had it happen to my rainbow six: vegas 2
