Xbox - Scratches on a disc

So my son kicked his xbox last nite in the dark, and when he went to play his game it was freezing. He took out the disc and saw 2 round scratches on it. I have a feeling the disc is ruined, but i've been hearing things that may give me hope, like some type of cleaner or taking it to gamestop or somewhere like that. Anyone have any ideas or experience with this?

Here's another remedy:  Cigarette ashes mixed with a small bit of mayonnaise.  I sh't you not.  Works on light furniture scratches, too.

auto wax. you can buy special CD/DVD commercial polishes and scratch removers, of course, but there are household items that will give the same end results. such as auto wax.  liquid auto wax is just as effective. if scratches are too deep, there isn’t much to be done. scratches on the upper label surface are impossible to repair. but on the shiny playing side of the disc, a quick polish with any liquid auto wax will often fix minor scratches. apply a few drops of the liquid wax to the damaged area, then wait for it to dry to a haze. buff away the haze with a soft dry cloth or cotton ball. don’t buff in a circular motion around the CD - do it across the disc.
