How to stop mold in my Dubai bedroom closet?« Back to Previous Page

That black speckling is classic mold growth, and your situation is very common in Dubai villas, especially during humid months. The closet on an outside wall is likely a "cold bridge" – the wall gets chilled by the AC while the outside heat and humidity try to penetrate, creating a perfect surface for condensation and mold.

First, move your leather goods to a drier area immediately and clean them with a specialist leather cleaner to prevent permanent damage. For the closet, wipe all surfaces with a diluted vinegar or detergent solution to remove the visible growth. Do not use bleach, as it only lightens the color and doesn't kill the roots.

To stop it from returning, you must control the humidity and airflow. Keep the closet doors open as much as possible to allow conditioned air to circulate. A small desiccant dehumidifier inside the closet can make a significant difference. Ensure the bedroom's AC unit is running efficiently and that its drain line is not blocked, as a faulty AC can contribute to high indoor humidity.

For a permanent solution, the root cause must be identified. This often requires a professional inspection with a thermal camera to pinpoint the exact condensation points on that outside wall. In many cases, the wall's insulation is insufficient for our extreme climate. Companies with a microbiology lab can also take an air sample from the closet to identify the mold species, which is crucial for assessing any health risks and verifying the cleanup was successful.
