Gentlemen,
Why not calm down a bit and be peaceful? Advice can be given but it's not a good idea to force it down the throat. In the end, everyone has to make his own experience. On the other hand, if I ask for advice and don't like the result, I might just say thanks and do whatever I think.
This said, I only can second that it's not the best idea to dump a shutter in cleaning fluid. I restore watches as well and can confirm the observations stated above. I see a lot of botched up movements and if the shift-make "maintenance" doesn't stop them running soon enough, the damages caused by this are often unrepairable. Shutters may be more forgiving because they don't run permanently. But else they are closely related to watch movements. I'd say, try your luck, it is your shutter.
