How to prevent mold in closet without AC always on?« Back to Previous Page

The black speckles are likely mold growth from high humidity and condensation, a common issue in Dubai's climate, especially in Marina apartments with their proximity to water. The problem occurs because when you turn off the AC at night, the temperature drops and the relative humidity inside that enclosed closet can spike past 70%, creating the perfect damp environment for mold to grow on organic materials like leather.

The most effective prevention strategy is controlling the humidity in that specific space. First, clean the affected items with a leather-safe antifungal cleaner and the closet interior with a diluted vinegar or specialized mold-cleaning solution. To prevent recurrence, improve air circulation. Leave the closet door ajar as often as possible and consider installing a louvered door to allow for passive airflow. A small, discreet desiccant dehumidifier or moisture absorber box placed inside the closet can make a significant difference by actively pulling excess moisture from the air; these are widely available at local hardware stores.

For a more integrated solution, ensure your apartment's AC system is serviced and its drain lines are clear, as a malfunctioning unit may not be dehumidifying the air effectively. If the problem is severe or persistent, a professional inspection can identify if there's a hidden moisture source within the wall itself. In many cases, a humidity meter is the best tool to confirm the environment is consistently below 60% RH.
