Well 'soak' maybe a strong term. Looking at an old owner's manual for the before mentioned does not show/tell you how to disassemble the bolt. The complete bolt is on the parts list, which is probably not made anymore.
Looking into the bolt I can see the firing pin spring is very dirty with gun oil/grease and spend powder I want to get that cleaned out. Would spray saturation work then blow it out with compressed air be ok?
