Do gun safes need temperature control? In the world of firearms, proper storage is as crucial as handling them safely. While many gun owners invest in safes to secure their weapons, the question of whether these safes need temperature control often arises.

This aspect of gun care is frequently overlooked, yet it is vital in preserving the longevity and functionality of your firearms. In this article, we delve into the necessity of temperature control within gun safes, exploring the reasons behind this requirement and its impact on your valuable firearms.

From preventing rust and mold growth to ensuring optimal performance, understanding the role of temperature control in gun safes is essential for every responsible gun owner.


Why Does Temperature Matter in Gun Safes?

Temperature Control

This question is crucial for gun owners who prioritize the longevity and safety of their firearms. Storing a gun in a safe is a responsible practice, but it's equally important to consider the climate inside the safe. The ideal gun safe humidity level is critical to prevent moisture accumulation, which can be detrimental to firearms.

Excess moisture in a gun safe can lead to rust and corrosion of metal parts and even damage wooden components. To combat these risks, integrating a dehumidifier or a climate control system into your gun safe is a wise decision. These devices help maintain a stable and suitable environment for your firearms, ensuring they remain in prime condition over time. The necessity for temperature control in gun safes is backed by both user experiences and the science of firearm preservation

Controlling the temperature inside the safe

As we know, a gun safe will get cold when you close the door tight. The air inside the safe will be moist so that it produces water. By using temperature control, the air will remain warm and not humid.

Your gun won't rust

Your gun is made from steel that may rust when it gets exposed to water. If you keep your gun inside the safe without temperature control, then the gun will rust. This will damage your gun components, so your gun won't function properly.

Mold will not grow on your gun safe

Mold only grows in humid areas. Your gun safe can be the best place for mold growth. Mold can cover the gun when you store it inside the safe for a long period of time. As the mold grows, rust will also get worse. Temperature control for a gun safe or a gun safe humidifier will solve this problem because it will keep the temperature inside your safe warm.

What Is the Best Temperature Control Product?

Eva-Dry E-333 Dehumidifier

Well, now you know that a gun safe is not enough to store your gun; you also have to buy a gun safe dehumidifier. Fortunately, you can buy temperature-controlled gun-safe products, so you don't have to think about the temperature problem in your safe. One of the most recommended temperature controllers for a gun safe is Eva Dry. Also, the use is very easy because you can just put the humidifier inside the safe.

FAQ Guide | What Readers Want to Know

Can I put a gun safe in an unheated garage?

Because garages are usually not climate-controlled, they are often too hot or too cold for storing firearms. Firearms should be stored in an area where they are protected from excess humidity but not too hot. As long as the safe isn't overheating, it should be fine. 

What temperature should a gun safe be kept at?

The perfect storage condition for your gun is between 30%-50% humidity at 70 degrees. If the air becomes dryer than 20%, you might have problems with the wood of your gun.

Can gun safes be kept in the cold?

When you put your guns away, the cold and dry should not cause any problems. If they have been wet, then there may be a problem. The cold can also change the viscosity of lubricants that are on your gun, which could cause a malfunction. But this is unlikely if it was just a little cold outside.

Are gun safe dehumidifiers supposed to be hot?

There are several kinds of dehumidifiers on the market, and some work better than others. The short answer is no. A gun safe dehumidifier that gets hot is usually not a gun safe dehumidifier at all, but a regular room heater in disguise. 


In conclusion, the necessity of temperature control in gun safes is clear: it is essential for preserving the integrity and functionality of your firearms. Humidity and temperature imbalances can lead to rust, mold, and deterioration, compromising your guns' safety and performance. Implementing a solution like the Eva Dry dehumidifier ensures that your firearms are stored in optimal conditions, safeguarding them against environmental damage. As responsible gun owners, it’s crucial to recognize that effective gun care extends beyond secure storage to include maintaining the right climate inside your safes.
