How to Eliminate Moisture in Your Gun Safe


A dehumidifier is going to be the best way for you to eliminate moisture in your gun safe. However, there are some other methods you can use to prevent moisture from getting into the safe. Getting to know all of your options can help you figure out which one is best for your needs.

Understanding Dehumidifiers for Your Gun Safe

When you are trying to keep humidity out of your gun safe, the best option is going to be to use a dehumidifier. These function by working to absorb all of the moisture that is present in the air and eliminate metal oxidation.

You can find these dehumidifiers in a number of styles, types and sizes and they will vary in complexity. There are both non-electric and electric options to choose from, as well.

Non-Electric Gun Safe Dehumidifiers

The most common types of non-electric dehumidifiers used in gun safes include:

  • Desiccant bags: These are the most affordable option and easy to use. They are also reusable and don’t (usually) have to be replaced.
  • Silica: This material will absorb moisture in the air and keep things dry, but you need to make sure they don’t come into contact with the metal on your gun because they can cause damage.
  • Rechargeable dehumidifiers: Another great option and are offered in a number of sizes and shapes with different capabilities.

Electric Gun Safe Dehumidifiers

An electric dehumidifier is going to use a different method to make sure that moisture does not get built up in your safe. Rather than having the ability to absorb moisture, the majority of these dehumidifiers will heat up the inside environment of the dehumidifier, which helps to prevent condensation of the air inside of your safe.

If your safe offers electrical access, there are several variations to consider. While electric dehumidifiers are more expensive than non-electric ones, they are well worth the investment. The dehumidifier can be installed on the safe’s wall or floor and have a detachable power cord that runs through hole that is in the safe.

Sealing Your Safe

An addition step you can take when you are trying to keep your gun safe as dry as possible is to invest in a sealant to prevent moisture from coming in. In most cases, the sealant system is designed around the area that is most susceptible to leaks, such as the door of the safe. Some of the most common sealants include caulking, silicone and foam, which can be applied to the interior portion of your safe’s door.

It is important to keep moisture out of your safe to maintain the integrity of the items inside. The tips here will help you figure out which option is right for you.
