With this, we have reached the end of our list of 8 Best Dehumidifiers for Gun Safes. Before you invest in one, carefully scrutinize the purpose, requirement, and expectation you have of dehumidifiers. Let’s head over to learn more about storing guns with care and the two major types of dehumidifiers that are ideal to safeguard a gun safe against moisture.

Will guns rust in safes?

Yes, they will! You might be surprised to learn that the rate at which guns rust in a safe is faster than when they are left outside. Storing firearms within a gun safe has its own challenges. The reason behind the rusting process is a certain chemical reaction, which is quite basic and simple to comprehend.

When iron or/and its alloys come in direct contact with water, moisture, or oxygen; it leads to a process called oxidation. In layman’s term, ‘Rusting’. The reason why rusting happens within a gun safe is the materials used in making, apart from the air within the cabinet that the gun comes in contact with. Gun safes are made using a thin steel shell. This is lined with gypsum board or drywall and carpet. These on the other hand are manufactured using formaldehyde and pyrite, which is nothing other than iron sulfide. Pyrite reacting with moisture and oxidation in the air doesn’t just stop with oxidation. It goes further and creates sulphuric acid as well which is notorious for aggravating oxidation.

The only metal that rusts is iron and its alloys. However, a similar chemical breakdown process that other metals experience is known as corrosion. Gun safes are also available in a complete steel build, but the guarantee that they will keep the process of rusting away is minimal. Unless they are completely airtight, they will be unable to keep away the other elements that cause corrosion and rusting. Temperature fluctuations within any cabinet are prone to happen, and this might lead to condensation which again makes rusting worse. It is essential to maintain the relative humidity level within a gun safe at within 50 to 55 percent, and the temperature at 70 degrees. This is where dehumidifiers come into play to make things easier and to entirely remove the chances of rusting.

What is the best way to safely store a gun?

There is more than one option to store a gun safely. But the best among them is using a gun safe. Owning firearms comes with great responsibility. You have to be cautious about where you store them and how you store them. Keeping firearms out of the reach of children and wrongdoers is CRUCIAL! Ensuring that your storage space has a locking mechanism is highly essential. This can prevent accidents for you and for those around you.

The best way to store a gun is by using a gun safe. They can be mounted anywhere to suit your convenience, they are designed to hold firearms, and can also have a digital lock system. There are various models available that you can choose from. They might differ to suit the type of firearms and the number of firearms they can contain. However, remember that a gun safe can store your ammo, but it is not designed to safeguard them against high humidity. Installing dehumidifiers is the wise choice to prevent your firearms from rusting away. Check the list above to pick out the dehumidifiers that will best suit your gun safe.

Best gun safe accessories available in the market

It is interesting to know more about the different accessories made for a gun safe and the thought that went behind making them. Here are some of the gun-safe accessories that can be truly helpful.

Light kits: It is obvious that your gun safe will be dark and get darker at night. Unable to see clearly to the back of your gun safe? There are lighting kits to help you out.

Dehumidifier: There is no denying that this is absolutely important and necessary!

Night access: Operating the safe at night when it is pitch dark is difficult. A night access light will make things easy for you by illuminating above the lock when it knows you are trying to open it.

Organizers: You can organize all the firearms that you have inside the safe using drawers, pistol organizers, on the door you can use door panel organizers, long gun organizers, and more!

Alarm: If there is someone trying to tamper with your lock, you ought to be signaled about it! There are security systems now available, that provide the option of getting notified on your phone if ever someone attempts to open the safe.

Mounting kits: Finding the right place for a gun safe and mounting it or installing it is equally important. Bolting it down to the floor is the best option! If there are firearms on the door panel, there are good chances that the safe might topple given the weight in the front. Solution- bolt it down!

Types of Gun Safe Dehumidifiers

Electric Dehumidifier Rod: This is one of the best options to keep humidity at bay within a gun safe. It is definitely expensive in comparison to silica gel, but it comes with no maintenance. If your gun safe has an inbuilt electrical outlet, you can simply plug in the rod inside the safe. If it does not have an internal electrical outlet, you can simply drill in to make space to run cords through. Most dehumidifier rods now available assure to consume minimal energy while providing maximum protection against humidity. These dehumidifiers take very minimal space and can adjust the relative humidity level within the cabinet or safe. Your firearms will remain rust-free and corrosion-free.

Desiccant Silica Gel: The cheaper option to prevent your ammo from rusting away is using Desiccant Silica Gel. These can absorb the excess moisture inside the cabinet. The advantage of using silica gel is that they are cheaper, reusable, can do a fairly good job. The disadvantage is that you have to keep track of recharging them (by reheating them in the oven), despite the color-changing indicator. Silica gel is a good option when it comes to a gun case; for larger gun safes you will require a good amount of silica gel to keep the rust away.
