When I first open a cd it gets the Mapleshade Microsmooth (ultrafine polish to smooth cd surface), I blacken the outside/inside edges and any clear plastic area in center top and bottom, then they get the Optrix cd cleaner treatment. Prior to listening, the Bendini Clarifier gets used and once a month I spray the top surface with Nordost antistatic stuff. I have also heard storage in the freezer works well but I'm afriad I might eat my cd as a midnight snack.
