How to control closet humidity to prevent mold?« Back to Previous Page

The fuzzy black spots you describe are a classic indicator of mold growth, directly fueled by the high humidity we've experienced. Your situation is common in Dubai villas, particularly on exterior walls which are susceptible to condensation due to the significant temperature differential between the air-conditioned interior and the hot, humid exterior. The AC unit opposite the closet cools the room's air, but if the airflow is obstructed or the unit's dehumidification function is not optimized, stagnant, humid air gets trapped in the closet, creating a perfect microclimate for mold.

To control humidity in that specific spot, a multi-pronged approach is required. First, immediately address the existing mold. I strongly recommend a professional inspection to determine the extent, as spores can spread and affect air quality. For the items, carefully clean the leather goods with a solution recommended for mold on leather. Do not simply wipe them, as this can aerosolize spores.

For prevention, you must increase air circulation and reduce moisture. Leave the closet doors open for several hours each day to allow conditioned air to circulate. Consider installing a battery-operated humidity monitor (hygrometer) inside the closet; your goal is to maintain relative humidity below 60%. For a more active solution, a small, portable desiccant dehumidifier or a renewable silica gel dehumidifying unit placed inside the closet can be highly effective for enclosed spaces. Ensure the room's AC unit is serviced; a dirty filter or low refrigerant can severely impair its dehumidification capacity.
