Hi Dave: It's not just Chandos. My recommendation is remove ALL of those foam sheets. The ones made in Europe definitely deteriorate as you described. The ones made in the USA probably will too. That kind of foam is notorious for turning to goo. I think European laws required different petrochemicals to be used in it, so the European variety seems to deteriorate faster, but it definitely happens with US products too. I can think of old (1960's and 70's) microphone cases, headphones, etc. where this has happened. I may be mistaken, but I think the US variety is more likely to deteriorate to powder that is somewhat sticky rather than a gooey ooze. In short, putting foam-rubber sheets inside CD cases was a BAD idea! I think it was common in the 80s and 90's, especially for 2- and 3-CD "jewel case" packaging. Before you toss your Chandos CD, try very carefully cleaning it with Naptha. I think CD plastic can handle Naptha without clouding up. I don't think isopropynol will dissolve the goo. -- Tom Fine ----- Original Message ----- From: "Dave Burnham" <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, September 29, 2015 12:37 PM Subject: [ARSCLIST] Chandos CD ALERT Last night I pulled out a Chandos CD set that I had bought in the mid-'80s and was horrified to see that the foam sheet that was placed between facing CDs was rotting and adhering to the CDs. This residue seems to be unremovable, rendering the CDs unplayable. When I got home I checked other Chandos box sets and found the same problem developing. Strangely I looked at other brands similarly packaged and there didn't seem to be a problem. However I am now removing these sheets from ALL such sets. db
