That should do it.

Or, if you can bring 120VAC cord into the safe, get a golden rod for the safe.

I second Flashes recommendation.

I am partial to Ballistol.
FIREARM CLEANING OIL & LUBRICANT
Keeps firearms protected – lock, stock and barrel.

"Gun cleaning and lubricantBallistol cleans and removes all types of bore fouling. Cleaning with Ballistol will save you time, minimize the need for brushing, and also form a protective film on your firearm. Due to its slight alkalinity, Ballistol neutralizes and dissolves black powder and corrosive ammo residue. In addition, Ballistol will beautify gun stocks, and prevent them from drying out. As a lubricant, Ballistol will never gum up or harden. With Ballistol, your entire firearm will stay lubricated and protected.

Ballistol is fully compatible with all metals including aluminum. However, Ballistol dissolves traces of copper, zinc, lead and tombac and can, therefore, be used to clean brass, bronze and silver. Read more about Ballistol for metal care.

Ballistol is an excellent smokeless powder cleaning solvent. It will “melt” carbon deposits in the barrel and chamber."

I usually get some when I am near Falcon Field.
