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
