How to clean an Xbox 360 game disc?

i got a cleaner that comes in a bottle at walmart and i forget what its called now , but it doesnt matter what brand its just that it comes in a bottle called disk cleaner and you spray 1 or 2 squirts on the disk and get a smooth cloth to wipe it. but dont do a circle motion go straight and rub it off the disk so it cleans nice and then you can play your game nice and when ever you need to use it agin do the same thing. (ps. thhe bottle has instructions)
