Ok, well I was cleaning the shee last night, and I use the Novus plastic polish on it every once in a while (kind of like wax for your plastics). And I was just letting my thoughts wander while I was cleaning when I suddenly thought, why should I spend 30 bucks on those disk doctor things, when I have a plastic polish right here. CDs are plastic, so why wouldn't it work? I took a few out there today, and damn if it didn't fix them all. All it took was a cotton rag, about 3 minutes per cd, and they play like new.
