How To Keep Moisture Out Of Gun Safe

A **gun safe** keeps **firearms and ammo** secure. It often stores valuable items too. But, placing a gun in a hot, humid place can be risky.

If you are not controlling the humidity level inside a safe, this could lead to some serious problems. Moisture is one of the most common enemies of a gun safe. If moisture gets in your gun safe, it can cause rust, corrosion, and even mildew. 

If you want to avoid these problems, you should make sure that your gun safe is airtight and has a good seal on its door. But what if you already bought a safe that is not sealed tightly?

What Can I Put In My Gun Safe To Keep It Dry?

So, what can you do to avoid moisture inside your gun safe? You can prevent the issue by using a humidity-absorbing material like silica gel or activated charcoal in your gun safe. The best way to keep moisture out of a gun safe is to use a gun safe dehumidifier. 

Ways To Keep Moisture Out Of A Gun Safe

Gun safes are designed to keep moisture out. However, given the nature of the product, it is not always possible to prevent moisture from seeping in. 

Some gun-safe manufacturers have developed products with a water-resistant lining that prevents moisture from getting into the safe. 

But if this is not an option, there are some other things you can do to keep your gun safes dry and prevent moisture from seeping into the safe:

1. Using Silica Gel Packs

The cheapest method to prevent moisture from entering your gun safe is to place a silica gel pack inside. A gun safe can become wet from water vapors inside. Just three silica packs can effectively prevent moisture from accumulating inside the safe. 

Do note that silica gel packs shouldn’t touch any of the guns inside directly. There’s a risk of the silica packs damaging the gun’s metal.

2. Dry Rice (DIY Method)

Dry rice is another method for preventing moisture from entering a gun safe. Using dry rice to keep a gun safe dry has several benefits.

This is due in part to the fact that rice is a natural desiccant. As a result, it can absorb moisture from any environment. Over time, dry rice absorbs moisture, causing the water to vaporize.

You could put dry rice inside the gun safe by placing a bowl of it inside. Keep in mind that it needs to be replaced every four months.

3. Electric Dehumidifiers

Using an electric dehumidifier is one way of preventing moisture from entering a gun safe. The purpose of an electric dehumidifier is to reduce and maintain the humidity level in the air. 

It is necessary to connect an electric dehumidifier to a power outlet in order to use it. The dehumidifier can be mounted to the wall of a gun safe, the cord can go through a hole in the back, and the dehumidifier can be plugged in.

Goldenrod’s electric dehumidifier can keep moisture from accumulating inside a gun safe. Electric dehumidifiers of this type are inexpensive. They typically have a rod diameter between 12 and 18 inches. It works by heating the surface to 140 degrees.

The dehumidifier ensures a constant temperature inside the gun safe when the temperature is at 140 degrees. As the gun safe is kept at a constant temperature, the humidity inside it drops.

The gun safe will remain rust-free because of this. When choosing a dehumidifier, keep in mind the availability of space and the capacity of the dehumidifier. The main disadvantage of electric dehumidifiers is their price. Those electric ones are more expensive than the non-electric ones.

4. Non-Electric Dehumidifiers For Gun Safes

The non-electric dehumidifiers work without electricity to absorb or desiccate moisture. Among the most popular are silica gel gun safes, which absorb humidity naturally.

In comparison to electric dehumidifiers, non-electric dehumidifiers are cheaper, easier to use, and do not require any special installation. Over time, some of them lose absorbency and need to be replaced.

However, there are some dehumidifiers that last longer than ten years that can be recharged. The units have an indicator that indicates when recharging is needed, and need to be plugged in or placed into the oven in order to do so.

What Is The Acceptable Gun Safe Humidity Level?

Humidity can be measured by using a hygrometer, which measures relative humidity and is used to determine whether or not there are enough water molecules in the air to support life. The acceptable humidity level for gun safes should be between 30 and 50 percent.

You should start by checking the temperature and humidity levels in your gun safe. In order to be considered an acceptable gun safe, the humidity level should be between 30% and 50% when the temperature is 60 or 70 degrees.

Using gun safe moisture control methods is necessary if the indicators in your gun safe are not so ideal. A number of different tools can assist you in keeping your gun safe and dry. Most people use electric or non-electric dehumidifiers to keep their gun safe to remain dry and moisture-free. 

What Causes Moisture Inside A Gun Safe?

For a better understanding of moisture in gun safety boxes, let’s look at what causes it.

When a gun safe is stored in a garage, shed, basement, or attic, where the temperature is not controlled and changes dramatically between day and night, condensation can form, and therefore moisture can accumulate.

Apart from that, the air inside a under bed gun vault stays sealed as in any small enclosed space, causing condensation and excessive moisture. If you don’t take gun safety moisture protection precautions, your guns are more prone to damage.

What Else Can You Use To Keep A Gun Safe Dry?

It is essential to have a revolver safe for home for safety and security. If you do not maintain proper humidity inside the gun safe, simply buying one may not be enough. Here are a few ways you can keep your gun safe and dry.

Moth Balls and Damp Rid

Additionally, damp-ridding products and mothballs can be used. Calcium chloride found in damp rids makes them effective at absorbing moisture. Use a mothball with caution because it contains toxic, so avoid getting it on your hands and your weapon as well.

Baking Soda

Sodium Bicarbonate, found in baking soda, helps absorb moisture in a gun safe. Make sure you replace the baking soda in the safe as soon as it loses its ability to absorb moisture.


It is also possible to use a bulb inside the safe as a cheap alternative. The bulb must be connected to a power outlet, like an electric dehumidifier.

To pass a wire through the biometric long gun safe, you may need to drill a hole at the backside. Some gun safes come with a pre-drilled hole in the back. The voltage of the bulb will be determined by the area inside the gun safe.

Final Words

There are some combination gun safes out there that protect firearms from fire, burglars, and misuse, but they don’t prevent moisture damage.

Basically, it’s up to you as the owner to control the level of humidity in your storage.  That is why I’ve shared some great ideas on how to keep a gun safe dry.

You can keep gun safes dry with dehumidifiers, dry rice, and silica gel packs. Guns inside safes can last longer if moisture is kept out.

Additionally, they can perform well on the gun range. Also, gun owners use these methods all the time.
