Gun Safes And The Effects Of Moisture And Humidity

There are many reasons to purchase a gun safe. Some of the most crucial reasons are to ensure your family remains safe. This could either be by keeping your guns away from members of your family who are unqualified or from intruders. A gun safe can end up deterring an overly inquisitive child as well as a burglar.

Another advantage to the use of a gun safe is that your gun will not be damaged as easily, as it will be protected by the safe. This can protect your gun from regular damage, such as scuffs and scratches. It will also protect your gun from other forms of damage, such as rusting and other unfortunate conditions.

Why Protect From Moisture?

Moisture and humidity are the main causes of rusting in firearms. Anything you can do to diminish these forces will go a long way towards keeping your guns in the best condition possible. Rust can have pervasive effects on the quality and effectiveness of your gun, so we’ll go over some of the main risks.

The first issue with rust is also one of the less damaging effects. You will find that moisture can lead to the degradation of the finish of your gun over a relatively short time. This is a minor concern as surface rust can usually be buffed out in short order and usually does not take deeper hold.

Regardless, you will want to avoid surface rust since it will make your gun look worse and it will necessitate work to be removed. If left untreated, you will find that surface rust on guns can sometimes end up getting worse and run deeper until it reaches the more delicate components.

Rusty Handgun

This risk of your firearm being ruined by rust is the main reason you will want to keep your guns away from humid and wet environments. If the rust begins to take hold ​in the components, you will have quite a bit of difficulty with your gun, and you will often have to stop using it.

Rusty internals are most gun owners’ worst nightmare. It is almost impossible to mitigate the damage of rusted components without having to replace the ones which have been effective. A lot of the internals of guns are delicate pieces of metal which are highly vulnerable to corrosion.

If some of these components get rusted, you may not only have difficulty with reliability. You will also have a measure of difficulty ensuring your gun is safe enough to shoot. Misfires and similar issues become far more likely when using a gun that has been damaged in this way.

As you can see, keeping your gun away from humidity and moisture is one of the best ways to ensure it will last you a long time. Many people make the mistake of thinking that it is only about looks. But, a gun with rusted internals can be a danger to you as well as everyone who shoots it.

Methods Of Eliminating Moisture

We will now take a look at some of the most effective ways to ensure that moisture gets removed from the interior of your safe, as even a good handgun storage safe on the market is highly susceptible to rust. There are a few options, some of which actively eliminate moisture and others which will keep moisture from getting into the gun safe in the first place.

Silica Gel

Silica gel is the most common method of eliminating moisture in most applications. It can also be put in your gun safe, as long as it is not in direct contact with your guns. This is the most affordable option you have at your disposal when it comes to ensuring that your weapons are not damaged by humidity.

Silica Gel Packs

You will find that silica gel is simple and affordable. This makes it an ideal option for those who are looking to save money but still keep their guns from being damaged. Some models of gun safe will come with silica built into the safe itself, which ensures there will be few issues with humidity from the start.


This option is one of the more pricey choices, but it is also the most effective by far. Dehumidifiers are meant to actively eliminate humidity in a particular area. While they are usually reserved for larger gun safes and cabinets, you will find that dehumidifiers are available for smaller models as well; they just cost more.

dehumidifier for gun safes

If you want to eliminate humidity and moisture as quickly as possible, this is the best option, and we would recommend dehumidifiers for gun safes that will be holding antique firearms. Since this option is a little more pricey than some of the other ones, you will usually want to reserve a safe with a dehumidifier for your more expensive guns.

Air-Tight Safes

An air-tight safe will not stop humidity from damaging your guns if it is the only feature meant to reduce moisture in your safe. Even higher end safes with biometric scanners are susceptible. What ​most safes do is prevent air from getting into the safe. But, this does not stop the air which is in your safe from ruining your guns with the humidity which is already present.

Safe Sealed Air Tight

When combined with silica gel or a dehumidifier, you will find that air-tight safes are the best option for those who want the most comprehensive humidity protection for their guns. While air-tight safes are more effective at keeping your guns from being ruined by rust, you will find that these safes also tend to be more expensive.

If you are looking to ensure that your gun safe will protect your weapons from moisture damage, you have a few options. The most affordable is silica gel, but the most effective choice is a combination of a dehumidifier and an air-tight safe.
