Getting Started
Moisture and metal have been in a constant battle since the inception of time. If you have any metal object lying around your house, rest assured, the humidity might impact its quality over time. Gun-safe dehumidifiers deal with these humidity problems. These nifty devices can keep guns and ammo stored inside them protected from moisture content. But even they require some recharging to bring back the battery power and keep things going. Read on to know how you can recharge a gun-safe dehumidifier, save your ammo, and keep your guns protected.
How To Recharge A Gun Safe Dehumidifier

Most Gun Safe dehumidifiers are built with a recharging mechanism. The most popular, easily rechargeable ones are Silica Gel Dehumidifiers. You will see a part similar to a screen at one of the canister sides, which flashes a specific color; this indicates how much juice is left before you need to recharge the canister. Showing a bright orange color would mean plenty of time before needing to recharge the battery. On the other hand, dark green indicates that you reached the maximum moisture saturation level. Although, the indication might differ from manufacturer to manufacturer. For example, in some canisters, purple indicates low levels, while bright blue indicates high levels. This blue is your cue to replenish the canister and resume protecting your metal objects, such as guns, ammo, and any critical material from humidity. Here’s how to recharge the canister.
Step 1: To recharge the canister, you need an operational oven. Any conventional oven will do the trick. Simply place the canister(s) inside the oven. There is no need to pre-heat it.
Step 2: Adjust the temperature to 250 degrees Fahrenheit. Be mindful that some brands require you to heat your canisters to 350 degrees. Leave the instruments inside the oven for 2-3 hours. Set a timer for the same time. Be sure to leave them in the oven until the prescribed time expires, even though the screen’s color has changed, from dark green to orange or purple to bright blue. Try to keep it inside for a total of three hours if you placed it inside when all the power was exhausted.
Step 3: After the lapse of three hours, put on some thick mittens and take out the canisters. Leave them out for 30 minutes or an hour, and allow them to cool down to touch. Do not, and we repeat, do not think about speeding up the process by hurling the canisters inside a refrigerator. Using a fridge might damage the entrails of the instrument or even make it defunct. Patience is the key here.
Step 4: Once it is cool to the touch, you can place it inside the gun safe and keep your firearms protected from humidity. When the color changes again, you can repeat the same practice, making it affordable and straightforward to keep your guns and ammo safe from moisture.
Conclusion
Gun Safe Dehumidifier is an excellent device to safeguard the durability of your expensive guns and firearms. If you live in a region high in moisture, it is all the more crucial for you to heed their maintenance.
