I've tried a multitude of sprays on my CDs including expensive ones like L'Art du Son. I've found the eyeglass cleaner fluid (under 3 bucks for a large spray bottle) sold at Walmart to be just as effective as anything else I've tried. In addition to cleaning the surface with the Walmart stuff, I demagnetize the CD with a Radio Shack video tape eraser. That's it ... for what its worth.
