How to Regulate Your Gun’s Exposure to Humidity

Jason Markey

A gun is an essential tool for self-defense, hunting, or shooting sports. And usually, investing in such a weapon also implies snagging the right tactical gear or accessories. In that case, you can check out for a wide assortment of high-quality products. You can also build your custom firearm and make your own receiver from an 80% lower. 80% Arms manufactures lower receivers that are some of the best in the industry.

That being said, like, with any other valuable item, it’s vital to protect your gun from the damaging effects of humidity. Here are some tips on regulating your gun’s humidity exposure so it doesn’t conk out when you least expect it.

1. Invest in a Hygrometer

A hygrometer is an instrument used to measure the amount of water vapor in the air. It’s common knowledge that high humidity can cause corrosion and rust.

A hygrometer can help you to avoid these problems by keeping track of the humidity levels in your home and, by extension, your gun’s exposure to corrosive elements. Many different types of hygrometers are on the market, but they all work in the same way.

According to the US Environmental Protection Agency (EPA), the humidity level in your home should be around 30%-60% to keep mold and mildew at bay. So, when stowing your gun, go for 50% humidity, which allows you to strike a balance between exposure to too much moisture (on the metal parts), and too little (which would cause cracking of wooden parts). 

2. Store Your Gun in a Climate-Controlled Environment

Store your gun in a climate-controlled space like a gun safe when possible. This helps ensure the relative humidity around your firearm stays consistent and protects it from extreme temperature changes that can cause condensation on your gun’s metal parts.

If you don’t have a climate-controlled space, consider storing your weapon in a moisture-resistant bag or container, along with a gel pack or desiccant packet. These packets are designed to absorb moisture and help keep the relative humidity inside the bag at a safe level for your gun.

You could also invest in a dehumidifier for your safe. This device helps remove moisture from the air and keeps your gun safe from the damaging effects of corrosion and rust. A dehumidifier rod is ideal for a large safe, while a larger unit would work best if you have an extensive collection of guns.

Alternatively, if you keep your weapon in the car, you could use a Zerust Vapor capsule. The capsule works by absorbing moisture from the air and creating a protective layer around your gun, thereby preventing corrosion. Plus, it sports an adhesive backing, allowing you to stow the weapon securely in various places – such as the console, glove box – you name it.

3. Select the Right Holster

If you carry your gun regularly, invest in a quality holster that provides good ventilation. This will help keep the weapon dry and protect it from body oils and sweat.

A leather holster is a good choice, as long as it’s made of high-quality materials that can withstand the elements. But, remember, leather tends to absorb moisture, so it’s ideal if you’re not going to be all sweaty – such us in summer.

Kydex (a hard plastic) could work well on a hot day as it doesn’t absorb moisture, thereby keeping your weapon dry. If you live in a particularly humid climate, consider a synthetic holster, which is less likely to absorb moisture and cause rusting.

4. Don’t Overlook the Importance of Proper Maintenance

Without proper maintenance, any tool is bound to break down at some point. The same applies to guns. So, take the time to protect your weapon from the effects of humidity by taking good care of it.

For instance, to guard against, oil your firearm regularly. This creates a barrier between your gun’s metal parts and the air’s moisture.

Many gun oils are available on the market, but not all are created equal. When choosing an oil for your gun, select one designed specifically for firearms. This ensures it doesn’t damage the finish on your gun while providing the level of protection you need.

Also, consider wiping it clean at the end of the day or when you need to stow it. Doing so removes skin oils and other contaminants that can speed up corrosion. And when cleaning your gun, use a clean, dry cloth. While at it, avoid getting moisture on the inside of the gun, as this can lead to rusting from the inside out.

Protecting your firearm from rust doesn’t have to be complicated. Ideally, though, keep your gun in pristine condition for years by being proactive – by putting the information, you gleaned from this write-up to good use.
