Thanks Photon46. I'll more than likely discard the sleeves now, since they may cause trouble with time. Better to clean the discs and keep them that way.
mold removal
I picked up some 16" recordings from 1944 that have mold on the discs and inside the sleeves. Was hoping for some good mold removal tips for the discs and sleeves, too. Would like to save the sleeves if possible. The sleeves are made of plain brown paper. Thanks in advance.
