It's happened again; somebody has given me an old M42 Praktica. Works fine mechanically, but the battery cover wont unscrew owing to battery leakage. I have got the battery compartment and cover out of the camera and am wondering about soaking it in vinegar? What other fluid might break the gunge down? WD40? Soak in boiling waterEasing oil? (there are no electronic gubbins, it is just two small pieces of metal.)
Many thanks for any ideas.
