For my Kodachrome and B&W slides and negatives I use a film cleaning solution with a very fine and clean microfiber cloth.

I learned about this from a post on this thread on Luminous Landscape
http://www.luminous-landscape.com/forum/index.php?topic=31377.0

Discussed in 'Reply #13 on: January 27, 2010, 07:35:30 PM', currently at the bottom of the thread.

I read the PDF a while ago and then forgot about it. Which was a big mistake, because I tried cleaning a circa 1961 Kodachrome slide with Pec-12 and it became quite messy, presumably because of some of the lacquer coming off. Luckily, I had scanned the slide before I did the cleaning.

Be careful with old Kodachrome slides.

I have used PEC-12 with PEC pads on many 1950s, and 1960s kodachrome slides. In fact they were so dirty I had to really scrub to get them clean. What that person was replying to may have been messing the dirt up making it look like the slide was "messed up" by the cleaning when in fact the slide may have just needed more cleaning to loosen up the dirt or fungus on the slide. I can visibly tell if a kodachrome slide is dirty by looking at it from an angle and seeing how reflective and shiny it is. I ended up cleaning these dirty kodachromes with PEC-12 until they were "squeaky" clean believe it or not.
