Favorite CD treatments?


What kinds of CD treatments (if any) do folks use? Magic pens, snandpaper, polishes, etc.

I use Kleenmaster Brillianize to clean CD's. Just spray on and wipe off with a microfiber cloth. Leaves no residue and sounds better. Much less expensive than audiophile cleaners/treatments. Most hardware stores carry it.
My Empirical Audio music player with an outboard optical drive and sophisticated programing has made treatment inaudible on playback from my hard drive.
Cream Electret, Xtreme AV Liquid Resolution, Red X Coordinate Pen, Cryo or home freezer, purple pen around outer edge/black pen around center hole.
