Ways to Keep Your Gun Dry and Moisture-Free

Preventing your arms from humidity is not that hard. With some very simple ways, you can continue storing them while making sure they’re always rust-free.

Using Silica Desiccant Packs

This is one of the cheapest ways you can keep your gun safe moisture-free. They will help to reduce humidity inside, keep it dry.

However, these silica beads can absorb moisture up to a certain amount, so you will need to bake them for about two hours in the oven at 250 degrees Fahrenheit to work again. You can also buy another pack if you don’t want all that hassle.

Keep in mind that silica gels are toxic, so don’t open the pack. Make sure they don’t come in direct contact with your hands or anything inside.

Using an Electric Dehumidifier

As humidity is the biggest reason for rust forming, getting a dehumidifier is all you need. An electric dehumidifier can help in keeping the inside dry consistently.

It works by increasing the temperature up to 284 degrees Fahrenheit and heating the inside, decreasing the water level. The device maintains a constant temperature preventing rusts.

At the same time, you might need to drill a hole in the back of the box to insert the dehumidifier. Getting a small one is convenient. Moreover, since it’s electric, you will need to always plug it in a power outlet for it to be working.

Using Moth Balls

You might have used mothballs to keep insects and moths away from your clothes, etc., but they also work as a desiccant! Mothballs, when kept in the open air, will evaporate quickly, but keeping in an enclosed place will not only prevent it from vaporizing soon but also absorbing excess moisture inside.

Please make sure they’re out of reach from the weapon and your hands as they’re toxic. When you use them up, replace it with more mothballs.

Using Dry Rice

A very easy method of reducing moisture is to use dry rice. It works as a natural dehumidifier or a desiccant.

Put a cup of dry rice inside the safe along with your guns. You may need to use a cup more, so make sure to check frequently the first time. Remember to replace the rice every three or four months as it will not be able to absorb for longer than that. If this method is not that effective, try the other methods.

Using a Bulb

This is a cheap way to add an electric dehumidifier inside the gun safe. The light bulb will produce heat and keep the inside dry. You will need to drill a hole on the back to pass the wire for this method to work though some come with a pre-drilled hole, saving you time. As an electric dehumidifier, you always need to plug it into an outlet.

Besides, the size of the bulb also matters. The larger the safe, the bigger the bulb you will need to produce a sufficient amount of heat to work.

Using Baking Soda

Baking soda is another great natural desiccant. It contains Sodium Bicarbonate, which will absorb the moisture inside, keeping it dry.

Similar to using dry rice, you will need to place a cup of baking soda inside the box for it to work. The bigger the size, the larger the amount you will need to put. However, just like other desiccants, it will soon lose its ability to absorb. So you have to check and replace it when it does.

Built-in Sealant-System

One way of ensuring that the inside your safe is dry is to buy one with a built-in sealant-system. It prevents condensation and keeps it constantly dry without the need for any other devices.

Typically, the inside of the door has the sealant. You can find foam or silica or caulking, etc. used as a seal to prevent it from getting humid once it’s closed.

However, if you already have one, you can add a sealant yourself. Like the built-in one, you can simply attach any of the sealant materials, silica, foam, caulking, etc. on the inside of the door.

Frequently Asked Questions

It depends on your location. If you live in a humid area, you need to consider getting one. But in a dry area, you can just open it periodically to keep it dry.

Q. Can I know what the humidity level is inside?

Yes, you can buy a hygrometer to check the percentage of humidity inside. Ideally, 50% and below is good.
