Moisture and Mold Problems: Preventing and Solving Them in Your Home

Keep Firearms Free from Rust & Corrosion
and Ammunition Dry with Dri-It®

Gun owners know the importance of keeping their equipment and ammunition dry and protected from harmful moisture that can allow rust and corrosion to start. Whether you keep your firearms in a lockbox, a gun carry/storage case, or locked away in a dedicated gun cabinet or fireproof safe, Dri-It® can help prevent rust and corrosion on your guns caused by moisture condensation. Keeping a pouch of Dri-It® in your ammo locker will help insure your powder stays dry and casings corrosion-free too.

The more airtight or watertight your storage may be, the more you need Dri-It®. Moisture enters and can be trapped inside these areas every time you open and close them.

Keeping Dri-It inside the storage area will insure that the moisture is quickly removed and trapped inside the gel, thus helping protect your guns and ammo from rust, corrosion and the damage caused by excess moisture.

Protecting your guns and ammunition from moisture damage is easy. All you need to do is simply place the suggested number of pouches in your gun storage so that air can flow around them. Then just sit back and let Dri-It® do it's job of absorbing excess moisture and helping prevent moisture damage like rust and corrosion from starting. Moisture penetrates through the printed label side of the Dri-It pouch where it is turned into a gel and is trapped inside the pouch. When the pouch gets full and feels completely ‘gel-like’, simply dispose of it in your standard residential waste and replace with a fresh pouch. No spillable tubs full of water and chemicals that can easily make a mess. Dri-It® is available in a 2-pouch resealable bag, thus allowing you to keep the unused pouch fresh and dry until needed.

 

The chart below provides a starting point for the number of pouches needed for different uses.
The ideal amount for your situation will vary depending on many factors, including your normal relative humidity levels; Corrosion/Rust starts forming at 45% RH and Mold & Mildew at 60% RH.
Storage volume is based on 50 cu. ft. (an area 5 ft. x 5 ft. x 2 ft.).


The actual amount you may need will depend on variables such as how watertight/airtight your safe is, if it is located in a temperature controlled area or not, how often the safe is opened, etc..

USAGE NOTES:

  • You do not have to worry about over-drying with Dri-It, and you cannot put too many pouches in an area. Dri-It is designed to lower RH no lower than 30%. Extra pouches will simply share the moisture load and extend the time between changing pouches for new ones.
  • When choosing a location to place the Dri-It® pouch, please consider the weight of a "full" pouch. A saturated pouch will weigh over ¾ of a pound! The adhesive on the pouch is designed to hold a full pouch for an extended period of time, however due to temperature fluctuations and other factors, primarily cleanliness of the mounting surface, the pouch may pull loose. This may happen before the pouch is completely saturated.
  • If possible, we recommend checking on the pouch in 30 days and at 3 months and 6 months. In 30 days it will have absorbed it's largest percentage of initial moisture. If the pouch seems less than 50% full, the next checks should be at 3 – 6 months. However, if the pouch seems more than 50% full, you may want to check on it in another 30 days to be sure it has not become saturated.
  • If you may not check on the pouch for six months or more, you should consider finding a flat surface to place the pouch on.
  • The printed side of the Dri-It® pouch is the side where the moisture enters and is turned into a gel. Blocking this will reduce the effectiveness of the Dri-It material to absorb moisture.
  • Occasionally there is a chemical reaction between the printing on the pouch and different surfaces. To avoid damaging paint, wallpaper or other surfaces, keep the printed side up. Do not place the printed side of the Dri-ItŪ pouch in direct contact with metal.
