How to treat mold and reduce closet humidity in Dubai?« Back to Previous Page

Our master bedroom closet, which is on an interior wall, has developed a few small patches of black mold on the leather bags and shoes we stored there. We keep the AC running most of the time, but I’m worried the lack of airflow in the closed space is causing humidity to build up. What’s the most effective way to treat the existing mold and what kind of dehumidifier or moisture absorber would you recommend specifically for a closed closet space in a Dubai apartment?

First, isolate and clean the affected leather items. Wipe them down with a solution of white vinegar or a leather-safe disinfectant, then dry them thoroughly in a well-ventilated area away from direct sunlight to prevent damage. For the closet interior, clean all surfaces with a microfiber cloth and a detergent solution. Avoid bleach, as it doesn't prevent regrowth and can damage surfaces.

The core issue is humidity. In a closed closet with an interior wall, moisture from the air condenses, creating a perfect environment for mold. Dubai's high ambient humidity, especially during summer months, exacerbates this. Even with AC running, stagnant air in enclosed spaces allows humidity to build up.

For a closet, a compact, electric desiccant dehumidifier is the most effective solution. These are designed for small, enclosed spaces and work efficiently at the lower temperatures typical of air-conditioned rooms. Alternatively, disposable moisture absorber pods with calcium chloride can help, but they require frequent replacement and are less effective for persistent issues.

The most crucial step is improving airflow. Leave the closet door ajar for a few hours each day and avoid overpacking items. If the problem recurs quickly or covers a large area (more than one square meter), a professional inspection is recommended to rule out a hidden source of moisture within the wall itself, which is a common issue here.
