Hi all,
I just wanted to clear on one thing. When you mention
"naphta", you are referring to lighter fluid? If so, is
there one brand that is better for our kind of usage than
other brands. What's good for my ZIPPO isn't necessarily
good for my shutter. I had some old dial set Compur
shutters that were kinda sticky. If getting them out of
their mount was a problem, (esp on 120 folders) then I
would detach the bellows and remove the optical elements
and stick the front standard into a bowl of lighter fluid
and leave it for the day. Evaporation is a problem so
doing it in the day, you could check periodically and add.
Then let it dry.
Cheers,
Bogdan
Naptha is the same as lighter fluid. Lighter fluid is
more expensive than buying naptha at the hardware store. I'm
not sure of the purity of either but Ronsonol seems not to
leave any residue. If you can find pure isopropyl alcohol it
should probably also be used as a second solvent or rinse
(not mixed together). I've been able to get 99+% isopropyl
at Long's Drugs locally although they don't always have it,
and Fry's, the big computer store. I suspect a lot iof
computer or electronics places have it. Long's Drugs was
cheaper. This is also what Kodak currently recommends for
cleaning the _emulsion_ side of film. Trichlor has become
very difficult to obtain although its a better cleaner and
non-inflamable.
