What Humidity Level Should My Gun Safe Be?

Having moisture inside your weapons storage it is a bad idea. They will rust.

In order to have your weapon vault at an ideal humidity level, you should use a good hygrometer and keep those levels at 50%. 

At What Humidity Do Guns Rust?

Rust has long been around as firearms were made of metal. This means that gun corrosion happens almost always all the time.

Steel and iron will rust if the relative humidity (RH) will be over 50%.

Hunters, sports enthusiasts, law enforcement officers, and the ones with concealed carry licenses may all take extra care in making sure that their weapons are properly oiled, cleaned, and kept in a dry and cool place.

A storage plan which involves anything less than vapor corrosion inhibitors will not ensure that your weapon will stay free from decay, particularly during summer.

Summer Increases Risks of Gun Rust

Technically, your firearm and/or its parts can always be at risk of rust whatever time of the year it might be. Remember that these items are made from metal and any type of metal which comes into contact with moisture and oxygen can get exposed to possible corrosion.

The carry guns, in particular, have high rates of corrosion considering that they often get into frequent contact with oils from human skin.

Sweat may cause more corrosion aside from the moisture since sweat is high in terms of salinity. You have to take note that salt is corrosive. If the environment is hot, you’ll sweat more. With this, there’s a greater chance that your firearm will be exposed to damaging salt and wetness.

Moreover, more people handle and use their weaponry at outdoor ranges when the weather condition is nice.

There is another reason why summer can be risky. It is the fact that the levels of humidity in the air are higher compared to usual. Warmer air basically holds more wetness compared to cooler air.

Even though cold winter air is saturated, it tends to contain less dampness compared to warm summer air. That is the reason why relative humidity is dependent on the temperature and one of the reasons why more rusting in a saltwater coastal region.

If you have problems with rust on your guns then check the video below that will teach you a simple way to clean the rust off.

Can a Gun Safe Be Too Dry?

You should take care of your safe if you want it to last. If it is too dry, it doesn’t really pose as many problems as dampness.

A hydrometer is a tool you must be using to keep an accurate watch of the level of dampness in your vault. The goal should be 50 percent relative humidity.

Humidity below 40 percent can cause steel and wood damage. If you are living in a humid area or particularly near rivers, lakes or sea, you’ll absolutely have to keep the moistness level low. The temperature must be around 60-70 degrees Fahrenheit.

It is also important to note that metal and wood have different requirements.

When it comes to metal parts, low humidity is required to avoid corrosion.

For wood, the humidity should be around 45%-50%. Some steel safes may be around 35%-40% relative humidity and 60-70 degrees, particularly during winter. Wood sages would take moisture during the summer season and heat up.

Therefore, you will need something to avoid moisture and must dry it easily once it is wet. The relative humidity for wood gun safes must be around 50 percent while the degrees may remain to about the same level as steel ones.

Temperature rises would affect the levels of relative humidity. Once the temperature rises, air would hold a greater amount of water. That is why temperature must be constant as well as not higher than seventy degrees. If the air is very dry inside the wood safe, it may crack and expand.

Avoiding the risks of moistness, dryness, theft, and fire basically starts with the right placement of your storage. If you don’t have a garage or basement, you may store it in your bedroom closet where risks of moistness and dryness are low. Coat closets are also a good option to place them.

Basements are not a good idea for vaults storage. It brings the most temperature and humidity problems. But, such issues may be resolved by placing the storage safe in the right place.

How Do You Keep Moisture Out of a Safe?

The fact that you purchased a weapon locker shows that you absolutely consider security your main priority. You have to know the ways to keep weaponry inside of this well-preserved. Knowing the ways to keep the locker free from damp and dry would do that.

A lot of people think that if you lock your firearms in the safe, you do not have to worry about anything. Well, this is the sad truth because it might lead to damaged firearms. Imagine getting a damaged weapon because of moisture in case of a home invasion. The risk is not worth it.

Below are some of the ways on how you can keep your gun locker free from dampness:

Silica Desiccant Packets

The first method you may consider to keep your vault dry is placing a silica desiccant inside. Click here if you want to buy these things from Amazon.

Silica desiccant packet is used to keep a lot of stored items dry. You might have seen some of these packets in the box of some products or when you buy shoes. These packets hold porous and dry silica beads, which absorb lots of moisture.

The only disadvantage of using such packets is that they’ll have to be regenerated for every few weeks. Since they absorb lots of moisture, you can be assured that they’ll reach their limits in the long run.

The process of regeneration is simple. The only thing that you should is to heat the packets for 90 minutes in your oven with a temperature of 250 degrees Fahrenheit. This would dry the packets and you can use them again. You may think of such packets as a reusable sponge.

Personally, I don’t like the hustle and I prefer the next method.

Small Dehumidifier

Buying a small dehumidifier for your safe is another common method you may take for consideration.

Dehumidifiers should be plugged to a nearby outlet to operate in a consistent manner. Some people drill small holes at the back of their vault to run the wire through.

Battery powered dehumidifiers are more convenient, yet it’s always a good idea to choose the one with a wired power source.

Light Bulb

If you want a cheap alternative to purchasing dehumidifiers, you can place inside a lit light bulb. The heat from your bulb is enough to keep the air dry and warm.

You’ll have to drill a hole at the back for its wire to run through. There are safes that have predrilled hole on its back for running wire through. This can help you save more time.

I personally don’t like this method.

Air Conditioned or Heated Room

Other weapon enthusiasts say that purchasing an extra dehumidifying unit isn’t necessary as long as the locker is in air-conditioned or heated area. They claim that you only have to open it up to let the fresh air in.

Although it sounds like a simple method, the surrounding environment should be considered. If it is situated in dry area or climate, dehumidification systems aren’t really needed. But, if you are living in a place with a humid climate, one of the techniques mentioned above must be considered.

Do Gun Safes Need Dehumidifiers?

The answer to this question is yes. Jewelry and weapons don’t do well in humid conditions since moisture may corrode anything metallic.

Keeping the damp out of your vault will make sure that your safe will last long and the items inside won’t incur any damage.

If you have decided to buy a dehumidifier, there are many options to choose from. Each one also comes with different features and functionalities.

Depending on what you prefer or your budget for a dehumidifier, choose the one that would benefit you the most. With this, you can guarantee that your weaponry will always maintain their good condition.

If you want to be on a safe side you will also need a dehumidifier. I wrote an article on what I consider the best dehumidifier for the gun safe.

Final Word

A gun safe is an important place where you keep equally important belongings aside from your firearm.

This is why controlling its humidity is a must to ensure that no damages will be incurred.
