Take one old revolver,remove the grips and soak the gun with brakekleen. Keep dry firing while you soak. Rinse with hot water:
Boil the revolver for one hour in a pressure cooker with Fairy:
Dry in an oven:
Clean with brakekleen again,let dry,oil to the taste inside out and enjoy a clean gun.
I ordered a Wilson spring set,this is such an accurate gun out of the box that I may do a proper polishing job... if the gun moves to my safe. Now I'm just feeling the main spring a bit.
This 1980 Mod 28 has been in a safe since the early 90's. I received it for test completely bone dry, it worked for a couple of boxes,heavy and "like new rough". I then lubed it and all kinds of problems started coming up,to the point that I suspected a faulty gun.
I cleaned with brakekleen and compressed air three times,in three days,still occasional problems and a strange feel. Trigger reset was changing randomly,hammer slipped out of cock etc bad stuff.
Now that I boiled it,everything settled back to normal.
