If it didn't, someone told me not to worry about the mold, as he claims it doesn't harm the leather. In any case, I didn't worry about the temperature of the freezer harming the leather.
Some success here: we had a very...wet year in the NE. A piano that I was waiting for winter to begin restoring got a nice sheen of green mold on the shellac, and it seems to have transferred to a bunch of stuff in the garage (thankfully, the mold doesn't/didn't seem to like the wood the keysticks are made from). I sprayed it with the 'generally accepted' dilute vinegar to clean it, but a week later, the mold was back. I accidentally [over]sprayed it with some Progold bike wash I had lying around (there was a bike with a leather saddle beginning to mold leaning on it), and where it over-sprayed, the mold died and didn't return.
I tested my theory elsewhere in the garage (cloth tape, other saddles, etc...) and it seems to have done it in. That is one product that gets two thumbs up
PS, shoot me an email at wschruba(at)gmail.com to get that camera out to you. It has to go by fedex/UPS--since it has a lithium battery, the USPS won't take it.
