[filmscanners] Re: Cleaning slides

["Arthur Entlich" <artistic-1@shaw.ca>]

If the snowfalkes, as you call them, are on the emulsion side and look
crystalline they are probably the result of bad processing.  I have one
roll like this, processed locally E-6 about 10 or more years ago.  I
suspect it was due to poor final rinsing and hardening.  The stuff I see
literally are crystals of some chemical, some of which come off with a
Q-tip without wetting, although not all come off this way.  Check a
slide that isn't too important and see if it is water soluble or not.

For this I think a water bath and good rinsing might work best.

BTW, Q-tips are bad for cleaning film with, the cotton can scratch the film.
