CD Treatment

I too have over 1000 CDs


I always wash them to remove any mold release residue


Over the decades I have tried many different treatments (including edge cutting, which works but the devices are expensive, time consuming to use and messy as the poly carbonate is shaved off the edge.


Overtime, in my experience all the treatments (including Novus) oxidize making the disc harder for the laser to read. When I play a disc I haven’t played in years I often find it dull sounding. I immediately rewash and BAM the sparkle returns

My experience with CD treatments (I've tried several) is not that they improve the sound of a fresh disc - they are better at removing the "digital hash" on CD's that over time have become magnetized, dirty, or whatever. You can hear the hash. Also useful when you get the dreaded "can't read or no disc" error messages. Take out your treatment, apply to cd and no more error message. Happens every once in a while. I am still using George Lewis's product from years ago. I'm sure others have their favorites. 

I recall that the Mapleshade Micro-Smooth made a big difference.  You buff the disk with some mildly abrasive polish, about the consistency of toothpaste.  I remember being very pleased with the results, but I don't have the patience or inclination to do it anymore.  Although, given the circumstances, things may change.
