I've had luck fixing scratched CDs by two methods:
1) Toothpaste - the all-purpose light abraisive.
2) Novus #2 plastic polish - more expensive, and not as nice smelling, but a
more effective polish for heavy scratches.
My bottle of Novus #2 has saved my buying at least three replacement
faceshields over the years, for my Shoei RF108V helmet. Time to replace the
helmet now.
