Just as an aside, if you have sticky processing gear, a tiny bit of anhydrous lanolin can work as a lubricant. A cine film processor manufacturer I know uses it on the PVC valves in their chemical recirculation loops and it does not spot the film. Of course, it may make a difference that their developer tank is 500 gallons and recirculated by 3 horsepower pumps!
Some run dry; some use clock oil. An old quick-and-dirty trick for cleaning and lubricating leaf shutters is allegedly to dissolve 5-10% clock oil in ether; slosh the shutter around in that for a while; drain it; and let it dry. A tiny amount of oil is left: not enough to gum up the blades, but enough to add a little lubricant on the bearings. I'd be grateful if anyone who has actually tried this could say if it works.
A very similar result can be obtained using 'Quickstart' from the auto supply store such as Canadian Tire. It is essentially ether and seems to leave just enough residue to lubricate.
