What Damage Can Too Much Humidity Do?
You may be wondering how much damage too much humidity can do to your safe, your guns, and other accessories. It’s not too dangerous in the sense of health and safety, but there are some issues that you need to be aware of when on the hunt for the best dehumidifier for gun safe.
It is worth considering that many of us don’t open our gun safe doors regularly, making moisture issues hard to notice. However, excess moisture within a gun safe can cause a number of problems.
- Damage to your ammo. High humidity can reduce or even stop the performance of bullets. Ammo is likely to be the first thing to be damaged if moisture levels rise too much.
- Growth of mold. A lot of moisture and dampness can lead to mold inside your gun safe. Mold is more likely to start on the foam-coated pieces that are attached to the interiors of the safe. You can clean mold build-up, but it’s best to prevent it in the first place.
- Rust build-up on guns. Even the most durable and toughest guns can suffer from rust problems if humidity levels are too high. Both the function and appearance of the guns are affected if moisture is left unchecked for too long.
- Rusty safe. Even a durable gun safe can suffer from rust in the long run. Rust can slowly eat metal over months or years before you notice it.
- Damage to other items in the safe: Too much moisture, or a high humidity level can damage other things such as documents, jewelry, money, and other valuables. In many cases, theses valuables are far more vulnerable than firearms.
The Different Types of Gun Vault Dehumidifiers
Silica gel is the most popular dehumidifier type for a gun safe. Silica gel is the same sort of material that comes packaged with products that need to be free of moisture. It’s a desiccant substance that naturally removes water from the air it touches.
You can easily place a silica gel dehumidifier inside a safe since they don’t need electricity to run. As they absorb moisture, the beads will change color. Once they completely change in color, the beads can be renewed by plugging the unit in. Then the cycle continues, and you put the device back in the safe again.
Even if you renew them every few weeks, these units can last for years. The frequency with which you recharge the silica gel depends on how humid the safe is.
While they won’t make much of a dent in a large room, this gel is quite efficient at removing moisture from a small space like a safe. You can have a good idea of how humid the atmosphere is from the color of the beads.
Rod-type gun safe dehumidifiers are electrical units that keep the air just enough warm enough to keep the interior of the safe a bit hotter than the outside temperature, allowing the air to circulate and keeping moisture at bay.
Rod dehumidifier are another very effective method of dehumidifying a small space. They keep your guns completely dry inside the safe. They’re very silent and relatively maintenance-free since they don’t require recharging. They do, however, need to be plugged into an electrical outlet to work.
Some people prefer this type because of its low-maintenance configuration. Other people prefer the cordless silica gel method. Both are effective and inexpensive, so it all boils down to personal taste and preference. There is no need to use both methods at the same time.
What Else Can Be Done to Keep Humidity Levels Low?
Dehumidifiers are not the only effective way of keeping your gun safe clean and condensation-free. Dehumidifying alone is a huge step, but you must also take the following countermeasures to protect your ammo and your guns:
- Put the gun safe in a cool, dry place. You must make sure that the gun safe won’t suffer from too much heat or moisture inside or outside. It is common to put a gun safe in the basement, but make sure that your basement doesn’t have dampness issues.
- Check inside regularly. There is a risk that you won’t even notice that humidity levels inside your gun safe are escalating. Checking your safe regularly will easily prevent this scenario.
- Use a fan. If the humidity does rise, place a fan near the safe to keep the air fresh and cool. Remember that this is only a temporary solution to a humidity problem.
- Place desiccant silica gel packs inside.
- The best moisture absorber for gun safe. These packs are like those that come in boxes with new shoes. They usually say “do not eat” on the outside. These silica gel packs are the same material used in a desiccant dehumidifier. Silica beads are ideal for ensuring moisture levels low in a small, enclosed area such as the inside of a gun safe. Remember, though, silica gel can be dangerous if eaten by children or pets.
- Use charcoal, baking soda, or coffee grounds. Place them in an open container inside the safe. Plenty of people trust these desiccant materials to absorb moisture in any scenario. However, you must replace them regularly, since they cannot be recharged like a desiccant dehumidifier can.
- Protect your guns from rusting. You may use numerous products such as sprays and creams to keep your guns free from rust. Remember that taking good care of your guns by allowing them to remain dry and clean, which is essential to keep them from rusting.
Humidity levels shouldn’t be kept too low, either, as the low humidity can dry up your ammo. Ideal storage conditions occur at 50% humidity. You must constantly reassess the climate where your gun safe is situated, as the humidity levels might change with the weather.
