How to kill mold and control closet humidity?« Back to Previous Page

Black mold on leather in a closet is a clear sign of excess humidity, a common issue in Dubai due to our high ambient moisture levels. The AC running constantly may cool the room but isn't effectively dehumidifying that enclosed space, leading to condensation on cooler surfaces like walls and your belongings.

First, address the existing mold. For leather goods, wipe them down with a solution of one part white vinegar to one part water. Test on a small, hidden area first to ensure it doesn't discolor the leather. Allow items to dry completely in a well-ventilated area, but not in direct sunlight which can damage them. For the closet interior, a solution of diluted bleach or a commercial mold remover can be used on non-porous surfaces, but ensure the area is well-ventilated during application.

To prevent recurrence, you must control the humidity. Start by inspecting the closet for any leaks from adjacent bathrooms or pipes, which is a frequent cause. Increase air circulation; leave the closet doors open for a few hours each day and consider installing a small battery-operated dehumidifier or a renewable desiccant pouch inside. For a more permanent solution, a professional can assess if your AC's dehumidification function is underperforming or if there's a hidden moisture source within the wall. In many villas and apartments, the constant cooling cycle can create significant temperature differentials that cause condensation on interior walls, which then leads to mold growth out of sight.

For a problem that is spreading, a professional inspection is wise to identify the core moisture source. They can use thermal imaging to find hidden condensation points and recommend solutions, which may include improving room-wide dehumidification or addressing insulation issues.
