I'm scanning in old 35 mm slides which are in these plastic snap-shut frames with plastic windows. I noticed that there is something wet in some of the slides, I assume a reaction from being in contact with the plastic window. Sometimes the exterior of the window also has a coating of something that would almost seem like it's simply water, except it has a sweet plastic smell to it.
If this IS something coming out of the plastic and or the slide, has anyone heard if this is something that should not be touched, or is it harmless.
Thanks so much!
