I read of an experiment some years ago in The New Amberola Graphic where a someone tried a perscription strength anti-fungal cream intended for athelets foot on a cylinder with a mold or fungus. He reported that after a wait of a day or two (cannot remember exactly) he wiped off the cream (and I think played the cylinder) and remarkably the growth was gone...of course the pitting caused by the growth was still there! I have not tried it myself.

It fills up the grooves and distorts the recordings. Some of the cylinders are so badly infected that they cannot be played at all. It appears to be a like a kind of fungus, but I am not sure. Has anyone come across this problem and come up with a non-destructive cleaning process?
