A gun safe desiccant is one of the best ways to keep your guns and ammo dry while in your gun safe. Due to the constant temperature swings in most cities, a significant level of condensation tends to buildup on the majority of firearm safes. Especially if you live in an area with high humidity.
This leads to rust, corrosion, mildew, and physical deterioration of guns of all sizes as well as ammo, and even cash. If you live in a very humid area, you can’t afford not to find an effective solution to get your guns dry all year round.
If this is your first time of buying a safe, it is recommended that you purchase a quality drying agent as soon as you order it. If you already own one, it is imperative that you decide on a dehumidifying solution as soon as possible.
Keep in mind, the following are “passive” silica gel dehumidifiers for your gun safe – there are active gun safe dehumidifiers we’ve covered in another article.

What Makes Up A Desiccant?
Desiccants are bags that contain silica beads or gel which operate by absorbing moisture in your safe until it gets full. Silica is the most preferred drying agent used in the manufacture due to its super absorption rate.
In fact, most silica bags can absorb moisture to almost 40 percent of its overall weight.
No matter which model you choose, it’s vital to know that there’s always a limit to the amount of moisture that can be absorbed.
Once the full moisture capacity is reached, these silica gel bags usually change color. This essentially alerts you to recharge or replace it.
Advantages of Desiccants
So why should you choose a silica gel desiccant over other dehumidifiers commonly used in firearm safes? Let’s take a good look at some of the reasons why.
No Need to Plug In
Most heaters such as the Goldenrod dehumidifier require plugging into an electrical outlet to be able to keep safes warm. Traditional blow drying machines also require electricity to work effectively.
These solutions work extremely well when used at home or in the office.
However, what happens when you want to store your gun safe in a hunting cabin somewhere in the woods with no access to electricity?
This is one of the reasons why silica bags are highly recommended. They require no form of electricity to keep the moisture in your safe to a minimum.
This makes it perfect for you whether your guns are stored at home or elsewhere.
Easy To Use
Placing a desiccant inside your safe is one of the easiest ways to keep your guns away from moisture. There are no complicated instructions for you to follow.
Your only job is to find the right size for your safe and mount it in whichever spot you decide.
It starts high-speed moisture absorption from your guns right from Day One so your valuables can stay dry. This makes silica gel dehumidifiers perfect for everyone from experienced gun collectors to complete novices.
Sure each model has a specified amount of moisture it can absorb from the air at any point.
The good news is that you don’t have to throw it into a bin once its absorption capacity is reached. That’s the beauty of silica gel desiccants.
They are perfectly reusable and come with specific instructions to recharge it when it reaches full capacity. Many brands instruct you to place the bag in an aluminum pan and slot into your oven at a specific temperature.
The color turns blue again once it is completely dry, indicating that the silica beads are ready to absorb moisture again.
Other desiccant manufacturers require their products to be plugged into a power outlet for recharging before it can start absorbing moisture again.
It is common practice that silica beads require recharging every 30 days or so of use.
Fortunately, every brand comes with specific instructions so just follow it for easy recharging.
A rifle/pistol safe desiccant is an affordable way to keep all sorts of firearms, ammo, and other valuables in perfect condition. While some dehumidifiers can cost about $100, silica beads are inexpensive.
With anywhere from $10-$25, you can get a multiple silica gel pack made up of a few reusable packs that can keep your safe dry for many years to come. If this isn’t affordable, we don’t know what is.
