My kid (I'm gonna kill him) went out playing with one of his Gamecube games in his jeans pocket. Now it has a cloudy ring of tiny micro scratches all around the outer perimeter on the "read" side and the 'Cube says it can't read it. These are not deep gashes, but only very light rub marks. I know there are disc repair kits sold that buff out such damage, but I don't want to spend $20 to fix something worth $20. I thought I might try a paper towel and moistened toothpaste, but it'll be a lot of work with no idea whether it'll actually work. Ideas? And, should I be extra careful to try to buff only going straight out from the center, or since I am basically only polishing, can I go around the perimeter in a circular motion? Waste of time?
