Have you ever taken a blanket out of summer storage and got hit by the smell of mold and mildew? How safe is that "special dress" stored away in that bin for safekeeping? Are you sure it was completely dry when it was put away? Does your closet have a damp or musty smell when you open it? Do your shoes never smell quite fresh, like they don't dry out between wearings? Help avoid these worries simply by placing pouches of Dri-It® in your closets and storage bins!

Dri-It® in your closet will absorb excess moisture in the air which allows your clothing, boots, shoes and other personal items to quickly dry out, and thus help protect them from the damage caused by excess body moisture, including mildew and odors.

A pouch of Dri-It in your linen or bathroom closet will help ensure that your bedding and towels stay as dry and fresh smelling as when they came out of the dryer.

Dri-It® is one of the easiest and most cost-effective ways to protect your clothes, shoes, boots, leather belts and purses, bedding and linens from mold and mildew.

Pouches of Dri-It® may be placed inside enclosed wardrobes or armoires, on closet or cabinet shelves, even in your dresser drawers to help keep your personal items dry and odor-free. Since there are no pails or bags full of liquid and chemicals to spill and worry about, there are no limits to the places you can

Boots and shoes can be kept fresh by always placing a pouch inside them to absorb moisture and prevent molds and mildew from forming. Do this from the first day you get a new pair and Dri-It® will help to keep your boots and shoes fresher smelling longer.
If you have items stored in plastic storage bins, simply remove the paper backing from the pouch to expose the adhesive back and stick the pouch to the inside of the lid where it will immediately start to remove excess moisture from your bin and help protect your items from mold, mildew, odors and other moisture caused damage. Moisture will penetrate 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 in your standard household waste and replace with a fresh pouch.

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 damp the items are when placed in storage, how airtight the container or closet is, how often the container is opened, etc..

  • 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-It® pouch in direct contact with metal.
