How to stop closet mositure and black mold permanently« Back to Previous Page

That cold, damp corner and black mold on leather goods point to a localized condensation issue, a common problem in Dubai's high humidity. The exterior wall is likely a "cold bridge," where the outside heat meets your cooled interior air, causing moisture to condense. The AC's general dehumidification isn't enough for this enclosed, poorly ventilated space.

First, remove all items from the closet and clean the mold off non-porous surfaces with a vinegar or diluted detergent solution. For leather goods, wipe with a damp cloth and a specialist leather cleaner, then allow them to dry completely away from the closet. Discard any severely affected porous items.

To stop the moisture permanently, you need to address the root causes. Improve air circulation by leaving the closet doors open for several hours each day or installing a small, battery-operated vent fan. Ensure items are not pushed tightly against the exterior wall; leave a gap for air to move. Using moisture-absorbing products like silica gel desiccant packs inside the closet can help, but they require frequent replacement.

For a more robust solution, consider having a professional assess the wall's insulation. Applying internal insulation or a vapour barrier can prevent the surface from becoming cold enough for condensation to form. If the problem persists or you see extensive mold growth inside the walls, a professional inspection with moisture mapping is recommended to identify the exact source and extent, as hidden mold requires remediation.
