Will this stuff help out old kodachromes with fungus? I would like to 
at least stop the stuff from further destruction of some of my
dad's chromes from the 50's.

also, does nose grease vary much depending on the manufacturer?
I seem to have had a lot more of it when I was a teenager.

I'm having a terrible time scanning the old kodachromes since ice
is causing other problems. It seems some chromes scan with ice
just fine while with others, the IR channel interacts with the dyes.
