First, you need to know the right humidity level of your safe by using hygrometer. Once you find out what is the right temperature, you know if you need to fight it. Understanding the importance of fighting these molds gives your documents a chance to survive and protect from such damage. 

You can follow these methods to prevent molds from growing inside your safe: 

  • You can place ½ cup of uncooked rice in a bowl and place it inside the safe. Dry rice will absorb the molds and moisture that circulates the safe.  
  • You can use DampRid to absorb moisture within the safe. DampRid contains calcium chloride crystals that draw out the molds, thus prevent dampness inside the safe.

What causes molds

Depending on the location of your fireproof safe, you may find that once you open the device, there are musty smell and moisture build-up inside. These substances can lead to mold damage to the items. By knowing what starts mold growth, you have a better understanding of how to prevent mold in a fireproof safe. You can figure out other ways on how to fight it and prevent breakouts. 

Mold grows from spores, which are everywhere. Spores are seeds that, when it grows, it becomes molds. Spores tend to find an area where there is enough moisture. From there, they will start to germinate and grow into molds. Sixty-five degrees Fahrenheit is more than the ideal temperature for mold to grow.  

Mold also needs nutrients and water. They can get foods from moisture where the humidity of the air serves as the primary chain. Moisture is everywhere, and it’s in your home, kitchen, clothes, and your body. Molds grow virtually everywhere, from bread, leather, and woods. Molds will continue to grow as long as there are moisture and air. 

So, the only solution to fight molds inside your safe is to prevent it from growing. 

How to keep the mold out of your safe 

Proper sunlight and circulating fresh air can help molds away. But fireproof safe is dark inside and tightly seam across, which do not allow the light and air to flow. This feature can start to grow molds, which targets your documents, and eventually destroying your valuables. But there are simple but effective remedies to shrink and wither these molds. 

How to prevent mold in a fireproof safe: 

  • Open the safe every week for 20 minutes to let the air out. 
  • You should transfer your valuable items in an airtight container before returning them to the safe. 
  • Clean and store the safe in a dry area. 
  • Do not place the safe in a high humidity area such as the basement. 
  • Ensure the airtight seams and seals are intact around the safe 
  • Before storing back your valuable items to the safe, ensure that these items are dry. 
  • Use desiccant products or dehumidifiers before returning the items to make sure that the device absorbs excess moisture or molds. 
  • If you have a new safe, it’s better to acclimatize the unit for 24 hours to prevent trapping excess moisture that results in molds. 

As soon as you notice mold starting to grow, you should remove your items from the safe. Clean and deodorize the safe using bleach cleanser to kill the molds within the safe. Before closing the safe, check the corners and areas where moisture may enter. It’s the responsibility of the gun owner to keep the contents of their safe, clean, and dry to maintain the value of their possessions. 

Humidity control

Controlling the humidity level in your fireproof safe is necessary as it keeps the value of the contents of the safe. While there are easy steps to control the internal temperature of your safe, you need to consider the location of the safe—the spot where you put your safe plays a contributing factor in mold growth.  

Condensation around your safe may begin to happen if the location of the safe is not ventilated correctly. Exhaust fans can reduce moisture where water and humidity circulate outside your safe. You can also open the windows to let the fresh air spread into your safe. It’s a good idea to maintain the proper temperature inside your home. 

The correct humidity level around the house should be between 30% and 50%, any rate higher than that can put the risk of mold growth to your safe. As we mentioned earlier, you should use a hygrometer to measure the humidity level inside your home. 

Here are some items that require protection from humidity: 

  • Paper documents and bills 
  • Photographs
  • Coins
  • Firearms


Keep in mind that staying dry is the best preventive measure against mold in a fireproof safe. Using the techniques on how to prevent mold in a fireproof safe does not require any heavy lifting or expensive products. There are solutions you can take and tools that are available inside your home. To make sure your safe is in good condition, practice proper maintenance inside and outside your safe.
