Mold and mildew are fungi that thrive in moist conditions and usually cause the damp musty odors commonly found in basements bathrooms closets and other areas with excess moisture like safes and gun racks. In addition to resulting in unpleasant odors mold spores will irritate someone with allergies and can result in health problems. The MoistureSorb® Moisture Absorbent Granules & Powder was specially developed to solve this problem using a unique dual mechanism. Firstly it absorbs excessive moisture from the air to lower the relative humidity thereby destroying mold and mildew. Secondly it eliminates musty odors on contact without covering them up with fragrances. For a breath of fresh air simply sprinkle MoistureSorb® granules or powder in areas with excessive moisture and smell the difference. It may also be inserted in open containers and placed in the area to be treated. To rejuvenate periodically simply heat in a microwave for 2-4 minutes or place in direct sunlight for a day and reuse. Replace when rejuvenation does not help. MoistureSorb® can work for years so it is very cost effective.
