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

Prevent Mold, Mildew, Odors & Rust from Damaging
Your Motorhome, Travel Trailer, Camper or RV by Using Dri-It®

While many people use their "home-on-wheels" everyday, for many more owners their Motor home, Travel Trailer, Camper or other RV is a weekend getaway trip, when they can, and the rest of the time it is closed up and stored away. This can often be for weeks or months at a time. You've made a sizable investment in your RV, don't let it be ruined by damage caused by excess moisture, primarily mold, mildew and their odors, when there is a very simple solution.

Pop-up campers that are not completely dry when stored can easily develop mold and mildew because the moisture is trapped inside when they are closed. Motorhomes and travel trailers are often exposed to the elements and rain and snow can easily be tracked inside on the carpets, and that moisture spreads throughout the cabin and can be absorbed by the furniture, drapes, and other cloth covered surfaces.

Placing pouches of Dri-It® throughout the motor home or trailer, or tucked into the pop-up camper before it is closed up, will help insure that the inside of your motor home, travel trailer, camper or any RV unit stays dry and free from mold, mildew, odors and rust.

All you need to do is simply place the suggested number of pouches in your motorhome, travel trailer, camper or RV 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 mold, mildew and moisture-caused odors from ruining your RV. 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. No spillable tubs full of liquid and chemicals that can easily make a mess! 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.


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 many moisture retaining items (furniture, bedding, carpeting, etc.) there are, how airtight the unit is, stored in a shed or in the open, 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 the "full" pouch. A completely saturated pouch will weigh over 12 ounces. 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 (cleanliness of the mounting surface, etc.), the pouch may pull loose after a while.
  • 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.
