Favorite CD treatments?


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

Herbie's Audio Mat is one of the only tweaks I've run into that a crowd of about 25 audiophiles also all agree is effective. The cost $20, so it's not too risky.
The only downside is that they lose stickiness and need to be washed w/warm water & dishsoap to regain the tackiness required to stay on the CDs. Cheers,
