How to stop mold in closet on outside wall?« Back to Previous Page

The black specks are likely mold growth, a common issue in Dubai's climate where high outdoor humidity meets cold interior walls cooled by AC, creating condensation. Your built-in closet on an outside wall is a prime location for this, as stagnant air and temperature differences trap moisture.

Start by cleaning all affected items with a solution of 70% isopropyl alcohol or a dedicated leather cleaner with antifungal properties. For the closet interior, wipe all surfaces with a diluted white vinegar solution. Discard any items that are heavily infested, as mold can penetrate porous materials.

To control moisture, improve air circulation. Leave the closet doors open for a few hours each day and ensure air conditioning vents in the room are not blocked. A small, battery-operated dehumidifier or moisture absorber like silica gel packs placed inside the closet can help significantly. For a more permanent solution, consider having a technician install a small ventilation grille on the closet door to allow conditioned air to circulate.

If the problem persists or you see extensive growth, a professional inspection is recommended to check for a more significant condensation issue within the wall cavity itself. In some cases, improper insulation is the root cause. A certified mold inspection, which includes moisture mapping and air quality testing, can identify the precise source of the humidity so it can be properly addressed.
