Re: filmscanners: Cleaning slides



The reason I say eeek, is because I was a mouse in a former life, and 
its habit...

No, really, because you're are playing with the pH of the film.  Ammonia 
is very base (alkaline), and I have no idea how it responds with 
formaldehyde hardener, etc.  I do know that I once was playing with 
household chemicals on some B&W prints and full strength household 
ammonia dissolved the emulsion right off the print.

Unless I read an authoritative source that says a certain concentration 
of ammonia is safe for film emulsions, you'll excuse me if I run into my 
hole in the wall and shiver ;-)
