Mildew on Photographs

PostMon Sep 12, 2016 4:15 pm

I recently bought a job lot of old stills. Aside from smelling musty, their surface is powdery to the touch. Holding them up to the light, there seems to be spots of mildew, similar to foxing on books.

In some cases the mildew is compromising the images, but I can't tell whether the spores are sitting on top of the emulsion, or the emulsion itself has been eaten away by them.

Does anyone have any suggestions about how to address this? Online ideas include 'leave them direct sunlight', which I certainly don't plan to do to 70+ year old photographs.

Thanks. There is also some useful stuff at this link - http://archivesoutside.records.nsw.gov.au/conservation-tip-no-5-removing-mould-from-records-and-archives/. For the moment, they're all well segregated from the rest of my collection, though the fact that the surface is powdery suggests that the mould is already dead, which is a plus.
