I brought several old and sticky shutters back to life without disassembling them. I simply detached them from the lens, took off the covering and gave them a firm splash with lighter fluid. Usually after this treatment the shutters worked perfect at all speeds.
However this technique has one shortfall. It seems to wash bits of dirt on to the blades and then dry out leaving them behind. Cleaning the blades with cotton buds soaked in lighter fluid or alcohol didn't work. I didn't dare to try other techniques.
Has anyone experienced the same problem and got around it?
