How to treat closet mold on leather bag myself?« Back to Previous Page

My bedroom closet on the outside wall has started to smell really damp, and I just found a patch of black spots on my leather handbag stored inside. We’ve lived in this Marina apartment for two years and it’s been fine, but this started after the heavy humidity last week. What’s the best way to treat this myself before it gets worse?

First, remove the bag and any other affected items from the closet immediately to prevent further contamination. For the leather handbag, use a soft cloth dampened with a 50/50 solution of white vinegar and distilled water. Gently wipe the mouldy areas, then follow with a clean, damp cloth to rinse. Allow it to air dry completely away from direct sunlight, which can damage the leather. Never use bleach, as it will ruin the material.

The damp smell indicates a humidity problem inside the wall cavity, likely due to condensation from the temperature difference between the air-conditioned room and the external wall. This is a common issue in Dubai's coastal apartments like the Marina, especially after periods of high humidity. Wipe down all closet surfaces with the same vinegar solution to kill surface mould, but this is only a temporary fix.

To prevent recurrence, you must address the moisture source. Improve air circulation by leaving the closet doors open and using a portable dehumidifier or a fan in the room. Check that your AC unit is running efficiently and not set at a temperature that causes excessive condensation on cold surfaces. If the mould returns quickly or the damp smell persists, the issue may be inside the wall itself. In such cases, a professional inspection with a thermal camera and moisture meter is needed to identify hidden condensation or leaks, as surface cleaning alone won't resolve a deeper building envelope problem.
