This is bad, this is very bad. Why is it that intelligent sane people do these
things to a beautiful precision machine like a rolleiflex. Solvents should not
be
used indiscriminately. Yes you need to use solvents, but just sloshing it
around
is not good. If you are lucky you will only have loosened some paint in a
non-critical
area, and the other bits still inside the shutter have not migrated to somewhere
critical. The actual amount of 'dirt' in a 'dirty' shutter is very small.
Really just old
lubricant + any stuff which has evaporated from paint etc. inside the shutter.
There
is usually very little dirt which has got into the shutter from the outside
(with exceptions
of course).

Noramlly one does not leave a camera sitting exposed in a dust storm.
Under normal use the camera spends most of its time inside a case, so
these is little oportunity for dirt to get inside. Also the various slots etc,
on shutters are not that large, so the entry of dirt is not a problem. Of
the many shutters I have overhauled, dust / dirt from the outside has
not been a problem.
