I use solvent inside the bore and cylinder very carefully not to get any on the finish. I don't let it soak. I wash it and wipe it. I wipe down the outside. I then soak the whole revolver with a gun spray silicone. Then I wrap the gun up in the s&w parchment paper and in the case she goes.

Should the nickel finish ever get foggy on the finish a little simi-chrome Polish will make it like brand new again.
