I have about 800-900 slides, mainly Kodachrome from the early 1990s. Attached is a photo of a photo and not the best quality - I haven't yet got a slide scanner so have just taken a digital photo of the projected image. It's Beinn Mheadhoin in the Cairngorms, one of my first Munros (hills over 3000' in Scotland) taken in July 1992, I think with a small compact camera that I was given by a friend's parents - possibly a Ricoh. The slides are all to varying extents dirty - I suspect what I am seeing is mainly mould of some sort (I live on the northwest coast of Scotland, it's damp). The first image is the 'mould' as it was, the second after a wipe with PEC12. Can anyone here confirm whether or not this suspicion, re: mould, is correct? [ Next question - obviously the slides are degrading, so I am going to scan them, but I need to clean them first. Cleaning them in the mounts works to some extent but it's difficult to impossible getting dirt out of the edges. I've worked out that Kodachrome mounts of the era easily pop apart, but is it feasible to reuse them? It looks like Kodak's processors used a small amount of adhesive to fix the film and perhaps also to stick the plastic mount together (it won't clip back together). Or would this just end up with a mounted image that was not flat enough to scan? Would I be better off with such as Gepe 7012?
