In the near future I intend to scan a lot of my older slides, partly also because in these bygone days I seemed to have a much better eye :? In addition, I want to digitalize many of the expedition pics from my colleague at work and also mine (since we travelled a lot together). Is there any non-destructive way of thoroughly cleaning slides which have collected quite a bit of dust through the years (partly due to unproper storage)? I don't want to remove all dust specks in PS since there will 100's of pics. Any advice is greatly appreciated.
