Tooth paste rarely worked, but what I did was weird whenever I had a scratched game. I would get a variety of random things and mix them together, such as shaving cream, toothpaste, banana mush, shampoo, and rub it all over. Rinse with diet soda, then rinse again with water. When you wipe things off of it, wipe in a circle, otherwise your game will be scratched even more.
