I normally use Brasso or Silvo a metal polish, the secret is using a lint free cloth in a straight line rubbing action... do not use a circular motion over the entire disc on a hard flat surface.
Beware if trying on a monitor or digi cam screen these usually have a anti reflective coating... and will surely be removed, these methods will not work on glass.
