How to Keep Moisture out of Gun Safe: 7 Reliable Ways

Where the temperature is not controlled and changes drastically between day and night, it is exposed to condensation and, thus, excess moisture.

Gun safes lock and close and are often made of steel, wood, or some highly durable material.

Although that is a problem and you don’t want water in the safe, your biggest adversary is actually going to be humidity levels.

Whether or not you have humidity issues will likely depend on where the gun safe is stored. For example, if yours is locked up in the garage, you simply don’t have temperature control there like you do throughout your home.

It’s the same concept if you store your gun safe somewhere like an outdoor shop, a basement, or even an attic. These are all common locations for gun safes and most of the time, they don’t have steady temperatures. In some cases, like the basement, they are simply more prone to high humidity and moisture.

Even a gun safe is kept in your temperature-controlled home. Most homes maintain humidity levels somewhere between 30-50% Trusted Source Controlling Indoor Humidity | The Master Group | Master Group Just as the temperature shown on your thermostat, the relative humidity level in your home has a direct impact on the air quality and the comfort of occupants. www.master.ca . Ideally, less than 50% is really the best, and closer to 30% is preferred. However, that won’t necessarily stop the gun safe from being subjected to humidity and moisture.

The fact that they are enclosed and locked up a lot could also cause them to hold moisture within. Even small gun safes like these best bedside gun safes can retain moisture.
