How to treat and prevent black mold on leather?« Back to Previous Page

Black speckling returning on leather items in a Jumeirah apartment closet is a classic sign of a mould issue, almost certainly due to the high ambient humidity. Leather is an organic material that mould can feed on, and the dark, confined space of a closet creates a perfect microclimate for growth, even if you're running a dehumidifier elsewhere in the room.

First, address the items immediately. Wipe the mould off the leather with a soft cloth slightly dampened with a 50/50 solution of water and isopropyl alcohol or white vinegar, then allow them to dry completely away from sunlight. Do not use bleach or harsh chemicals, as they can damage the leather. For valuable items, consulting a professional leather restorer is advisable to prevent permanent damage.

To treat the closet itself, empty it completely. Clean all interior surfaces with a mould-killing solution (like the diluted vinegar or alcohol mix), paying close attention to corners, baseboards, and the back wall. This is often the coldest surface, where condensation forms from the contrast between the room's AC and the humid air. Ensure the closet is completely dry before returning your items.

For prevention, the root cause is humidity and lack of airflow. The most effective strategy is to improve ventilation. Leave the closet doors open as often as possible and consider using a small, battery-operated dehumidifier or moisture absorber like silica gel packs inside the closet itself. Keep items in breathable fabric bags, not plastic, which traps moisture.

If the mould returns quickly after a thorough cleaning, the issue may be more widespread within the wall or building envelope. In such cases, a professional inspection with moisture mapping and air testing can identify the hidden source of moisture, which is essential for a permanent solution in Dubai's climate.
