[filmscanners] RE: SS4000 fixes to improve quality--dust removal

["" <snsok@swbell.net>]

The mirror in the SS4000 is accessible only through a small slot unless one
wanted to disassemble the entire carriage mechanism (bad move...) I can
reach it with a air can flexible plastic tube. I could also reach it with a
high-quality artist's brush. Would that be safe to use? Even with the air
can, there is still a fine dust layer that seems not to budge.

There's no practical way to get a cloth or chamois to the mirror.

My experience with easily smudged or scratched surfaces, like front
surfaced mirrors, is that almost looking at them causes problems.

I caution people to not use anything but air before doing any cleaning
of these type of surfaces, I would visit my local camera repair shop and
see if they carry any special types of cleaning fluids or tissues to use
with internal lens or front surface mirror surfaces.

  My best experience has been with using a new properly treated leather
chamois designed for lens cleaning.  Finding the right fluid that will
remove oily residue without leaving streaking or damaging the surface is
tricky, so again I'd try to get some advice from a camera repair shop
personnel who works on these types of components.  Even lens cleaning
tissue with silicone can scratch a front surfaced mirror quite easily.
