Modern firearms are robust machines designed to handle the intense pressures that come with firing rounds. Yet, despite their strength, they're vulnerable to moisture damage. So, keeping them in a dry environment is key. Although storing them in a gun safe is a great idea, it can lead to condensation due to temperature fluctuations and limited air circulation.

Exposure to such conditions can cause corrosion, pitting, and even damage to wooden stocks over time. The primary culprit? High humidity. Although most people wipe down their guns after using them in wet conditions, leaving firearms in humid environments for prolonged periods can cause rust.

Luckily, there's a solution – DampRid for gun safes. However, there are various factors to consider when using this product. If you're asking yourself, "Will DampRid work in a gun safe?" you're not alone. We'll explore some of the most common questions both new and seasoned gun owners have about using DampRid to protect their guns from humidity damage.

Damprid Basics

Will Damprid Work in a Gun Safe?

DampRid Refillable Moisture Absorbers are an excellent ally to assist you in protecting your firearms. They are a dehumidifier with desiccant technology that can avoid condensation, decrease humidity levels and trap excess moisture in your safe. This product helps you get rid of musty odors and that awful, sticky, humid sensation that comes with long summer days. Not only is humidity uncomfortable for you, but it can also encourage harmful mold growth in your home.

 DampRid will it work on a safe?

What Is Damprid Made Of?

Damprid is a calcium chloride crystal-based product. These crystals are in a particular container that keeps the hardened calcium chloride separate from the liquid brine it turns into when it absorbs moisture. DampRid is mostly calcium chloride, with traces of sodium chloride and potassium chloride thrown in for good measure.

Hanging bags, big capacity tubs, refillable, giant tubs, and disposables are among the five options available from Damprid. This is fantastic since you may select exactly what you want at any time (and none of them will break the bank!). The instructions on how to use the product are on the package and are quite straightforward. 

Can You Use Too Much Damprid?

DampRid is a no-fuss, easy-to-use material in powder form. All it asks of you is to place it in the desired area, and it will take care of the rest on its own. The great thing about DampRid is that it requires no energy input. The crystals within the product work by actively drawing moisture from the air. As they absorb water, the powder hardens, eventually forming a pool of water at the bottom of the container.

However, like any product, following the recommended usage guidelines is essential. Overuse won't necessarily improve its effectiveness and could lead to unnecessary waste. Monitor the conditions in your safe and adjust the amount of DampRid used as needed.

What Makes Damprid Work and Absorb Excess Moisture?

When DampRid's natural crystals come in contact with air, they absorb excess moisture and disintegrate into a liquid brine over time. What sets this product apart from the rest is that it will not dry the air to the point that it is dangerous to plants, animals, or clothes. Their patented solution is septic-safe and environmentally friendly.

DampRid is most effective in rooms with a humidity level of 60% or above, making it suitable for those who live in humid climates. Even if you live in a dry climate, you may use it in the bathroom, kitchen, and laundry room. Due to the nature of their use, these rooms become moist and might retain stale odors.

Including fragrant beads among the crystals is a fantastic way to keep your closet or drawers smelling fresh. Having the ability to purchase hanging bags for a small closet improves everything.

DampRid Hanging Bags

The DampRid container's lid locks, preventing undesired spillages. The design is one that can easily fade into the background of any environment. If you opt to set the product on the floor, the safety cover prevents youngsters and dogs from playing with it.

Damprid Safety

Is Damprid Poisonous to Dogs?

Despite DampRid being an all-natural product, it should be kept out of the reach of children and even pets. Avoid getting it in your eyes or on your skin, and don't eat it. It comprises calcium chloride, an inorganic mineral salt that is non-toxic. Calcium chloride, the active component in DampRid, is harmless and does not generate any harmful vapors or odors.

Is Damprid Safe To Breathe?

DampRid is a home device that absorbs excess moisture in the air to prevent mold and mildew growth. Calcium chloride, the active component in DampRid, is harmless and does not produce irritating vapors or odors.

DampRid is safe for everyone. However, if you have a baby or pets in your home, you should use it with caution. The maker promises consumers that this is a non-toxic product that will not be dangerous if they accidentally put it in their mouths. However, OSHA considers the calcium chloride in DampRid to be a hazardous substance. Handle this product with caution. It is possible that exposure will cause nausea or discomfort.

Damprid Maintenance and Troubleshooting

What To Do If Damprid Spills?

Using DampRid can help wipe out damp, musty odors and prevent mold from thriving in moist conditions. It removes moisture from the atmosphere and also helps to keep moisture, mold, and mildew at bay. 

It comprises calcium chloride, an inorganic mineral salt that is non-toxic. Use a wet/dry vacuum or a towel to absorb as much liquid as possible. Continue to pour ordinary tap water onto the spill to dilute the concentration. If you don't dilute or clean the spilled liquid, the surplus moisture will stain the inside of the safe. Despite the fact that DampRid is an all-natural product, it should always be out of the reach of children and dogs. Avoid getting it in your eyes or on your skin, and don't eat it.

Handling Hardened Damprid Crystals:

If you notice that your DampRid crystals have hardened, you might wonder if you should split or chip them apart. The answer is no; there's no need to break them apart. The hardening of the crystals is a natural part of the moisture absorption process. It indicates that the DampRid is actively working to remove excess humidity from the environment.

Can You Reuse Damprid?

The Moisture Absorber container is reusable and can be used over and over again. Empty the liquid into the toilet and refill it with new DampRid crystals. The active component will need to be refilled every 45 days or so, depending on your humidity conditions, but the container should last several years. Depending on a home's temperature and humidity levels, each dehumidifying bag of Damprid can last up to three months or 60 days.

Wherever moisture is a concern, this product helps to maintain humidity levels in a gun safe.

Can You Pour Damprid Down the Drain?

When the crystals run out, you must discard the bag and pick up a fresh one. It is important to keep the product out of the reach of children and house pets when using or storing it. The liquid is septic-safe and may be poured down the toilet. Small amounts of salts, such as the CaCl in DampRid, are unlikely to harm a septic tank, but we wouldn't recommend it since, depending on the volume and condition of the tank, you might invite a drain obstruction.

Damprid Effectiveness

How Long Does It Take for Damprid to Start Working?

The crystals in this product absorb any extra moisture from the air in a matter of minutes. The crystals solidify into a solid mass. Then they start to disintegrate, and liquid drips into the bottom chamber. It might take a few days for the fluids to start dripping. DampRid in closets, linen presses, and storage places protects costly garments and materials.

For big areas, use Hi-Capacity products. DampRid products will need to be changed more frequently in high-humidity or high-temperature situations. When the humidity in the air hits 60% or above, the DampRid crystals begin to draw moisture out of the air. This keeps the air from drying out too much while preventing mold formation, as mold is unlikely to thrive at humidity below 60%.

Will Damprid Cause Corrosion?

With prolonged exposure to moisture, metals in a gun safe can start to corrode. That's where DampRid comes in handy. This top-notch moisture absorber can be a real game-changer in maintaining your firearms. It works by drawing in and trapping moisture from your safe, thus reducing humidity levels. Once your DampRid runs out of crystals, simply discard the old one and grab a new pack from your local store.

Why Is My Damprid Hard?

Calcium chloride, a non-toxic inorganic salt compound, is the white crystals in a gun safe dehumidifier. When with other salt-based products, they harden as it captures more moisture. The product has been specifically designed to suck the moisture from the air right away. 

The crystals solidify into a solid mass. A quick shift in either temperature or humidity might trigger this. Run water over the formation until it melts to remove the crystals. 

How Long Does Damprid Last?

Wherever moisture is a concern, DampRid crystals absorb moisture to generate and maintain the ideal humidity level. Depending on the humidity and temperature, a dehumidifying bag will work for up to 60 days.

Depending on your humidity conditions, the active component will need replacing every 45 days, but the container should last several years.

FAQs What Readers Want to Know

What can I put in my gun safe to absorb moisture?

Using silica gel packets can help absorb moisture and protect your firearms in a gun safe. Three packets should be enough, but remember, they should never touch the guns directly. Also, using a moisture absorber like DampRid helps in reducing humidity by capturing the moisture inside your safe.

What can I put in my safe to keep moisture out?

Airing out your safe every couple of weeks is a good practice to keep moisture out. Silica gel packets are again useful here. Additionally, monitoring humidity levels inside the safe with a compact humidity gauge or smart sensor can help determine if there's a need for a dehumidifier like DampRid, other calcium chloride-based products or something different altogether like an Eva Dry Dehumidifier.

Can you put DampRid in any container?

A clean margarine jar works as a great holder for desiccant. DampRid, a product designed to draw moisture from the air, can be placed in virtually any container. It comes in refillable, disposable, and hanging forms. Once the calcium chloride crystals dissolve, the container needs to be emptied. 

Where is the best place to put a dehumidifier in a gun safe?

A dehumidifier can help keep moisture out of gun safes and prolong the life of your firearms. Place the dehumidifier at the bottom of the safe for it to work effectively. Monitoring the conditions inside your safe with a humidity and temperature monitor can also be useful.


In conclusion, protecting your firearms from the detrimental effects of humidity is crucial, and DampRid can be a powerful ally in this task. As we've discussed in this article, DampRid has the potential to significantly reduce moisture levels within your gun safe, thereby minimizing the risk of corrosion and damage to your firearms. But remember, it's not a 'set it and forget it' solution - regular maintenance and monitoring are key to ensuring the optimum humidity levels are maintained in your safe.

Lastly, while DampRid is a useful tool, it's also part of a broader strategy that should include proper gun care, safe ventilation, and climate control. With these steps, you can ensure that your guns remain in top-notch condition for many years to come. Stay safe, and remember - a well-maintained firearm is a reliable firearm.
