Dry Rice:

You might already have a handy solution with the silica gel I talked about. But, what if you cannot find some right now but you must dry up the safe immediately? Well, let’s go even cheaper, yet more of a DIY solution with dry rice. Dry rice is a very well-known solution for humidity issues because of its capability of absorbing moisture from the air.

The process is pretty simple; put a cup of dry rice inside the gun safe to keep the moisture out. What makes this idea unique apart from being cheap is, rice doesn’t have any sort of chemical emission issues. Therefore, you won’t get your sensitive items damaged inside the safe; just replace the rice every 4-6 months.

Baking Soda:

Developing a bad odor inside a gun safe is a common phenomenon that nobody likes; not even enthusiasts. Sodium bicarbonate, on the other hand, does a great job not only removing odor but also keeping the moisture out.

However, the biggest issue with this process raises if you have to hole the shell yourself.

Many gun safes have holes in the back as built-in for the safe for easy installation. You can run a wire into the safe, attach the bulb inside, and power it from an external outlet. But if you don’t have it pre-drilled, you can do drill the back of the safe and do the job.

It’s one of the most effective ways to keep your gun safe out of moisture and humid situations. There are three types of dehumidifiers depending on which situation you’re in and how you want to do it:

  • First, you can go for electric humidifiers that need an external outlet, just like a bulb. You have to make a custom hole for that unless you have a pre-drilled one.
  • Secondly, you have the battery-powered ones that don’t need external outlets and sit inside just fine.
  • The last type is, desiccant dehumidifiers that neither need external outlets, nor battery power. Rather, they contain highly absorbent materials to soak in the humidity and moisture.

Use A Moisture Absorbent

If you already have a damp gun safe, you can consider getting a moisture absorbent keep it out of moisture. There are many types of gun safe moisture absorber available that are good at absorbing moisture such as Damprid. These absorbents contain calcium chloride crystals that attract the moisture around where you put it.
