I am sure I was flamed either here or on a camera repair forum for making
much the same point. I regard fluching a mechanism with solvent as being
a real bodger's trick, likely to do more harm than good.
I know it's not quite the same thing but on the small mechanical parts
of hydraulic systems I work on, I find that some of them are almost
impossible to get sorted out unless you dunk them in a bucket of petrol
for a while and flush the worst of the crap out before you even *start*
to take them to bits.
Of course the key here is that you do still take them to bits and clean
everything properly.
