How to prevent mold in Dubai's humid closet?« Back to Previous Page

Our master bedroom closet, which is on an interior wall, has a persistent damp smell that just won't go away. I noticed a few small black spots on a leather bag I stored in there last month, and I’m worried it’s the start of a mold problem. We run the AC constantly, but the dehumidifier mode doesn't seem to help in that enclosed space. What’s the most effective way to prevent mold from growing in a dark, unused closet here in Dubai?

The damp smell and spots on leather are classic signs of a hidden mold issue, likely due to condensation from the temperature difference between your cold AC room and the warmer interior wall. In Dubai's climate, this is a common problem in enclosed, unventilated spaces.

First, increase air circulation. A small, battery-operated closet dehumidifier or a simple silica gel desiccant bag can help, but it's a partial solution. For a more permanent fix, leave the closet door ajar for a few hours each day to allow the room's conditioned air to circulate inside. If possible, avoid pushing furniture directly against the exterior wall, as this creates a dead air space where moisture accumulates.

For immediate action, wipe down all interior closet surfaces with a vinegar or diluted bleach solution to address any surface mold you can see. Remove the affected leather bag and clean it thoroughly according to the manufacturer's instructions to prevent spores from spreading.

Since the smell is persistent and you've seen physical evidence, this suggests a deeper issue. The wall itself may be holding moisture. A professional inspection with a borescope can identify hidden mold growth inside the wall cavity, which DIY methods cannot address. They can also use a moisture meter to pinpoint the condensation source. If the problem is extensive, remediation followed by applying a mold-resistant primer before repainting is the most effective long-term solution.
