How can too much humidity cause damage?

You might be curious about the damage humidity can cause to your safe, guns, and accessories. Although it’s not dangerous for safety and health, there are some things you should be aware of when searching for the best gun safe dehumidifier.

Consider that most people don’t open their gun safe doors often, which makes moisture problems difficult to spot. But, excessive moisture in a gun safe can lead to a variety of problems.

  • Ammo damage. High humidity can affect the performance of bullets. If moisture levels are too high, ammo will be the first to be damaged.
  • Growth of mold. Mold can form in your gun safe if there is too much moisture or dampness. Mold can be more easily found on foam-coated parts that attach to the safe’s interior. Mold buildup can be cleaned up, but it is best to avoid it.
  • Rust buildup on guns. Humidity levels too high can cause rust problems in even the toughest guns. Moisture levels left unchecked can cause damage to both the gun’s function and appearance.
  • Rusty safe. Rust can cause long-term damage to gun safes. Rust can slowly consume metal over many months or years, before you even notice it.
  • Damage to other items inside the safe: High humidity levels or too much moisture can cause damage to other items, such as documents, jewelry and money. These valuables can be more susceptible than firearms in many cases.

The Different Types Of Gun Vault Dehumidifiers

Silica Gel

Silica gel is the most common type of dehumidifier for gun safe.  Silica gel is also used in packaging to prevent moisture from entering the product. It is a desiccant material that naturally removes water and air from it.

Because they don’t require electricity to operate, you can place a silica Gel Dehumidifier in a safe. 

The beads will change in color as they absorb moisture.

 The beads will change completely in color once they are dry. After that, you can plug the unit back in to renew them. You can then continue the cycle and put the device back into the safe.

These units can last years even if they are renewed every few weeks. The humidity of the safe will determine how often you need to recharge the silica gel.

Although they won’t cause much damage in large rooms, the gel can remove moisture from small spaces like a safe. The color of the beads can give you an idea of how humid it is.

Rod Models

Rod-type gun safe humidifiers are electric units that heat the air just enough to allow the safe’s interior to be a little warmer than the outside temperature. This allows the safe to circulate air and keeps moisture away.

A stick dehumidifier is another effective way to dehumidify a small area. They protect your guns from moisture inside the safe. They are quiet and require no recharging. To work, they must be plugged in to an electrical outlet.

This type is preferred by some people because it’s low-maintenance. Some prefer the cordless silica jelly method. Both methods are both effective and affordable.

Use charcoal or baking soda.

Place them inside the safe in an open container.These desiccants are trusted by many people to absorb water in all situations. They must be replaced regularly because they are not recyclable.recharged like a desiccant dehumidifier.

Keep your guns safe from rusting.

Sprays and creams are two options to prevent your guns from rusting. It is important to take good care of your guns and allow them to dry out. This will prevent them from rusting.
