How to stop closet mold in high humidity?« Back to Previous Page

Our master bedroom closet, which is on an interior wall, has developed a recurring black mold problem on our leather bags and shoes. It seems to flare up every summer when the humidity gets insane, despite us running the AC constantly. We’ve tried wiping it down with vinegar, but it just comes back a few weeks later. What is the most effective long-term solution to control the humidity in that specific area and stop this mold from returning?

The recurring mold in your closet is a classic Dubai humidity issue. Your AC is likely set to a temperature that causes condensation on cooler interior walls, creating a perfect breeding ground for mold on organic materials like leather.

First, improve air circulation in the closet. Leave doors open daily and consider installing a battery-operated vent fan or a small, standalone dehumidifier designed for enclosed spaces. Ensure the room's AC vent isn't blocked by furniture, as this restricts airflow to the closet.

For the mold itself, vinegar is a surface cleaner but not a long-term solution. You need to address the moisture source. A professional inspection can identify if the wall has a condensation problem or a hidden leak. They use moisture meters to find the exact source, which is often not where the mold appears.

The most effective long-term solution is often controlling the climate in that specific area. After a proper mold remediation to remove the active growth, installing a ductless mini-dehumidifier or having an HVAC specialist adjust ductwork to better serve that room can create a stable environment. In severe, recurring cases, this is the only way to stop the cycle.
