What is the best method to clean your PS3 game disk from bad scratches?

I recently bought Uncharted 2 and it was the best game I ever played. Thanks to my stupid little brother it is badly scratched and damaged. I tried toothpaste, bananas, wax cleaning, and all those methods. They all work fine, but sooner or later the issues come back. Any ideas on cleaning it?What is the best method to clean your PS3 game disk from bad scratches?Uncharted 2 really is the best game ever. I can't believe how amazing the graphics look. Go to CDFixers.com. They will fix your scratched disc for a few bucks. They guarantee their work too or your money back. Worked great for me.
