How to treat and prevent mold in humid closet?« Back to Previous Page

Based on your description of black speckles on leather items in an exterior wall closet in Jumeirah, you are likely dealing with a classic case of surface mold growth, exacerbated by the current high humidity and lack of ventilation. This is a common issue in Dubai villas due to the intense humidity, condensation from year-round AC use, and thermal bridging in external walls.

The most effective treatment begins with addressing the source. Move the affected items to a dry, well-ventilated area immediately. For the leather goods, carefully wipe them down with a soft cloth lightly dampened with a solution of water and isopropyl alcohol (a 60/40 mix). Allow them to dry completely away from direct sunlight. Do not use bleach or harsh chemicals on leather.

For the closet itself, you must clean and disinfect the surfaces. I recommend using a hydrogen peroxide-based cleaner or a dedicated EPA-approved fungicidal solution. Scrub the walls, shelves, and flooring thoroughly. It is critical to identify if the mold is only on the surface or if it has penetrated the building materials, such as the drywall or insulation behind, which would indicate a more serious hidden problem.

Prevention is key. To avoid running a dehumidifier constantly, focus on improving airflow and controlling moisture. Install a battery-operated humidity monitor (hygrometer) in the closet. Ensure there is a gap between the stored items and the external wall. Leave the closet doors ajar periodically to allow air circulation from the room's AC. Consider installing louvered doors or a small, passive ventilation grille to promote cross-ventilation. Using moisture-absorbing desiccants like silica gel packs inside the closet can also help.

For a definitive identification of the mold type and to ensure there is no structural compromise, a professional inspection is strongly advised. Our certified inspectors at Saniservice use thermal imaging and moisture meters to pinpoint the exact moisture source and assess the full extent. We can then recommend a targeted remediation and prevention plan specific to Dubai's climate. For immediate assistance, please call us at 800-MOLDS or email hello@saniservice.com.
