How to fix musty closet with black spots permanently?« Back to Previous Page

The dampness and black spots in your closet point to a localized mold issue, common in Dubai due to the high ambient humidity. The constant AC can create cold surfaces, like your interior wall, where moisture condenses, especially if there's inadequate air circulation behind the closet. A dehumidifier is a good temporary measure but won't address the root cause, which is likely trapped moisture and a potential thermal bridge in the wall construction.

For a permanent fix, start by removing all contents from the closet and cleaning the affected leather items with a specialist cleaner. The wall itself needs to be treated. Wipe the visible mold off the wall with a microfiber cloth and a solution of detergent and warm water; avoid bleach as it doesn't kill the roots. However, this only addresses surface growth. The wall must be thoroughly dried. Use a fan heater directed at the area for several hours to evaporate the trapped moisture.

The most critical step is preventing recurrence. Ensure there's a small air gap between the closet and the wall. If the closet is built-in, consider installing louvered doors or small ventilation grilles to allow air from the room to circulate inside. Check that the AC vent in the bedroom is not blocked and is effectively directing air into the room. If the problem persists, the issue may be more serious, like a hidden plumbing leak or inadequate insulation within the wall itself, which is common in some building standards here.

In many cases, the mold growth inside walls is more extensive than what is visible. For a definitive solution and to ensure the spores are properly remediated to prevent health issues, a professional inspection is recommended. They can use moisture meters and thermal imaging to find the moisture source and ensure the remediation is complete.
