Do guns rust in gun safes?

Guns are prized possessions and investments for many gun enthusiasts. They hold not only material value but also sentimental and historical significance. It is therefore crucial to keep them protected, secure, and in top condition.

One way to guard guns against theft, damage, and other hazards is by storing them in a gun safe. However, gun owners might wonder whether their firearms will rust in these secured enclosures.

In this article, we will answer this question and explain everything you need to know about rust prevention in gun safes.

What Causes Rust in Guns?

Before we dive into the discussion, let’s first understand what rust is and its causes.

Rust, also known as oxidation, is when iron and oxygen react in the presence of moisture or water. A gun’s metal parts, such as the barrel, bolts, and triggers, are usually made of steel, which is prone to rust.

Other factors that contribute to rust formation include exposure to air, saltwater, sweat, and oils. Heat and humidity levels can also speed up or slow down rust development.

Therefore, guns that are not properly stored, maintained, or used regularly are at higher risk of rusting.

Do Guns Rust in Gun Safes?

The short answer is yes, guns can rust in gun safes. However, it depends on the type of safe, the storage conditions, and how you store your firearms.

A gun safe can provide protection against burglars, fire, and other external threats. However, it cannot control the internal temperature and humidity levels, which are the primary culprits for rusting.

Some gun safes have better rust-prevention features than others. For instance, some safes are equipped with dehumidifiers, which can remove excess moisture from the air and surrounding surfaces.

Other safes have special coatings or materials that absorb or repel moisture, such as zirconium dioxide or Nitrocellulose lacquer. These features can help reduce the risk of rusting, but they are not foolproof.

Moreover, if you store your guns in a safe that already has rust or is exposed to other rusty items, your firearms can also get affected.

Therefore, it is crucial to choose a quality gun safe, clean and maintain it regularly, and follow rust-prevention practices to keep your guns in excellent condition.

5 Tips for Preventing Rust in Gun Safes

Here are some ways to prevent rust in gun safes and prolong the lifespan of your firearms:

1. Use a dehumidifier: As mentioned earlier, a dehumidifier can help reduce the humidity levels in your gun safe. There are various types of dehumidifiers, such as electric, rechargeable, and desiccants. Choose the one that fits your needs and replace or recharge it when necessary.

2. Apply rust inhibitors: Rust inhibitors are chemical compounds that can neutralize or slow down the rusting process. You can use products like gun oils, sprays, or silicon cloths to protect your guns. Make sure to follow the manufacturer’s instructions and avoid over-application.

3. Store guns with a barrier: Placing a protective barrier between your guns and the safe can prevent direct contact with moisture or rusted items. You can use gun socks, silicone-treated cloths, or even paper towels. However, avoid using non-breathable materials that can trap moisture and cause more harm.

4. Clean your guns regularly: Cleaning your guns after use or storage can remove any dirt, oils, or salts that can contribute to rust formation. Use a gun cleaning kit with proper solvents, brushes, and patches to achieve optimal results.

5. Monitor the environment: Finally, keep an eye on the temperature and humidity levels in your environment. You can use a hygrometer to measure the relative humidity and adjust accordingly. Avoid storing your gun safe in areas that are too humid, damp, or prone to water damage, such as basements or garages.


In conclusion, guns can rust in gun safes if the storage conditions are not ideal. However, you can prevent rust formation by using a dehumidifier, rust inhibitors, protective barriers, regular cleaning, and environmental monitoring. By following these guidelines, you can ensure that your guns stay secure and rust-free for years to come.
