I report this fact to warn all other fellows: today I opened a CD box of mine, one of the first I ripped back in about 2006 and likely never opened again since. It is a very old 4 CD jewel case box issued in 1985 by Archiv Production (actually I bought my copy brand new in 2004, but don't know the real build date) and had two foam sheets between opposite facing CDs to keep them firmly in place. Unfortunately by time the foam had somewhat disintegrated and glued to the CD surfaces in many a contact point.

I had accurately ripped FLAC copies of those CD (so no reason to lose my temper! wink.gif), nevertheless in polishing them I tried to be not too forceful for fear of scratching the upper surface where the actual data are written, so some little debris and spots of melted foam could still be seen. I tried a new ripping test run and AR verification went all ok.

Two of the biggest factors in polymer degradation are UV light and ozone, though I doubt that either of those is a big factor in northern England.
