CD Treatment

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. 

I was under the impression scratches were not good on CDs. 

when I was tweak crazy, I would de-mag each CD before insertion into the player. I also "green" inked the CD edges until I figured out I did not hear any difference. And I would also copy CD's onto blank "black" CDs. I tried a lot of things without much sonic improvement. And now I don’t even play CD’s anymore as I stream everything.

You know you went too far down the rabbit hole when you start writing ‘x = PRESENT TIME and ‘x 26 ‘x in red pen on all your CDs. Coloring cassettes also.
