Firearms should be kept in a secure gun safe.

Rust is a prime enemy of firearms, and leaving them in a gun safe with no air circulation allows moisture to accumulate. This creates a perfect situation for rusting. A rod-type dehumidifier is used by many gun owners to prevent moisture. The heated air rises from the floor out of the vents, taking any moisture along with it.

Step 1

Arrange the contents of the safe to ensure good air circulation between the firearms and from the bottom to the top of the safe.

Step 2

Detach the electric cord from the dehumidifying rod and lay the rod on the floor of the safe, toward the front.

Step 3

Pass the electric cord through the hole in the back of the safe and reattach it to the rod.

Step 4

Turn the rod on.


Tape a note to the inside of the safe door with a six-month maintenance schedule to test the rod to ensure it is still working.
