CD Treatment


I read recently on a thread here that there are ways to treat CD’s so that they sound better. What are some of the easier treatment methods that you’ve tied that have worked?

My CD player is an old Simaudio Supernova with front loading tray.

I have about 1500 CD’s

Thanks

You color the edges with a sharpie.   Green I think.      Total internet legend and snake oil..........but why do I have the feeling someone will tell me I'm wrong?
Tom, I’m cursed with an allergy to beer. But not wine or scotch. I may just try that treatment tonight! Grab my babe and swing around the dance floor ( our living room).😀
