8 inch floppies, decaying

I've had the goo from the adhesive of 5.25 inch 360k disk come through the nice liner and make gobs on the disk. I tried several thing but found that isopropanol worked without removing any of the magnetic material ( maybe s tiny amount that was likely loose already ). I'm not saying it would be the same for 8 inch disk. Once working I did copy them to floppies without liners.

Do not use isopropanol to clean floppies--you'll wind up with a soft oxide coating and a brown rag. Were these mine, I'd first remove them from their jackets and then bake them and then clean them with distilled water and perhaps a couple of drops of a wetting agent (Kodak Photo-flo is a good) choice--a couple of drops goes a long way). You should be good to go--at least my experience tells me that. --Chuck
