How to treat mold in UAE closet and best dehumidifier?« Back to Previous Page

Black spots on leather in a closet on an exterior wall are a classic sign of condensation-related mold growth, a very common issue in Dubai due to high outdoor humidity meeting cold interior walls from constant AC use.

First, address the source. The wall is likely a "cold bridge," where outside heat meets the cooled interior surface, causing moisture to condense and mold to grow unseen behind or on the wall. Wipe down all affected items with a solution of white vinegar or a dedicated leather-safe mold remover, then dry them thoroughly in sunlight if possible. For the closet interior, clean all surfaces with a diluted vinegar or detergent solution. However, this only treats the surface; the mold will return unless the moisture issue is solved.

For a closet, a compact, electric dehumidifier with a built-in humidistat is far more effective than disposable moisture absorbers. Look for a model with a capacity of at least 10-12 liters per day and a continuous drainage option. Place it inside the closet to maintain humidity below 50-55%, the level where mold growth is inhibited. Ensure the closet isn't overpacked, as air needs to circulate.

Crucially, these are temporary fixes for the symptom. The underlying cause is the wall's condensation. For a permanent solution, the wall cavity needs to be inspected for insulation gaps or leaks. Given the mold is already affecting belongings and you suspect it's spreading, a professional inspection is strongly advised to assess the extent of the growth within the wall and identify the precise condensation point. They can use thermal imaging to spot the exact cold spot and moisture meters to quantify the problem.
