Sorry if I overexpanded the "old thread".  Seemed like we wanted to clean
shutters and not get our health zapped -- so there was a natural seg-way.

I've a couple Kodak cameras that need their shutters cleaned, which is
why I have particular interest.

My plan was/is to use a mixture of liquid dish soap (one that claims to
really cut the grease...), water, plus a little of some stuff I got at
Home Depot that's anti-rust.  The anti-rust agent is sold there for power
washers.  You put a little in the pump water when finished so that it
doesn't rust in the pump where the water sits.  Something like $10/quart.

I'd then put the mixture and shutter in a container and immerse the
whole thing in a Dentist-office ultrasonic cleaner (they're fairly
powerful).   Then sit in front of a fan to dry (after maybe washing
w/water in the ultrasonic cleaner as well ????).  I plan to "zap"
most of the water out of the mechanism before drying using compressed
air (also available in that same Dental office :-).  I shouldn't think
drying time would be all the long.  How long does it take for water to
do nasty things?

Would this work w/o any bad side effects, or should I just hold my
breath for ten minutes and use toluene (etc), and "to heck with it"?

Even with water-cleaning, it seems like the shutter might be cleaner
that it was before w/o cleaning out my nose and lungs at the same
time.  I've been over-solvent'ed a few more times than I'd like to
admit, and would just as soon find some other "solution".  :-)

I'd also be interested in any experiences with trying things in
this direction.
