I was the boat guy with the odd, unproven idea...
here is the text from the old post...
----------------------------------------
Up here in the humid boating areas, they sell a product called Mil-Du-Gas bags. Meijers used to carry them for your basement, but now the boating supply stores carry them too.

Anyway the idea is you hang them in a humid confined space (a big baggie might work) and it kills the spores. I have used them in my basement.
A bit more web checking came up with this:
http://www.scorecard.org/chemical-p...=MIL%2dDU%2dGAS
seems the active ingredients are:
PARAFORMALDEHYDE
1,4-DICHLOROBENZENE
Ahh, better living through chemicals. Maybe I was better off before I knew WHAT was in the things.
Anyway, what about tossing one in a baggie with you mildewed leather for a month or so. These Mil-Du bags are made out a a filter paper kind of material and the powder & stuff doesn't come out of the bag, it's supposed to become airborne. It's not a strong chemical odor, kind of a baby powder scent to the thing.

John Sabato then warned about experimentation on a fine luger holster, and suggested the testing on a less valuable specimen.
So that was the idea - it does the trick in boat interiors and basements, we just don't really know about fine leather of any age.
