How to treat and prevent mold in a humid closet?« Back to Previous Page

Based on your description, this is a classic case of high ambient humidity leading to mold growth on organic materials like leather. Here’s a technical breakdown of how to treat the items and remediate the closet environment, specific to our climate in Dubai.

First, the items: For leather goods with visible sporulation (the black speckles), immediate isolation is critical to prevent cross-contamination to your clothing. Do not attempt to clean them with household cleaners, as this can set the stain and feed the mold. Leather requires specialized biocidal treatment by a professional restoration company to kill the mold spores without damaging the material. For clothing, a hot wash cycle (above 60°C) with a fungicidal additive is effective if the infestation is surface-level only.

The root cause is the elevated humidity level within that enclosed space, exacerbated by the building's age and lack of adequate ventilation or dehumidification. To permanently stop it, you must address the moisture source. This involves a professional inspection with thermal imaging and moisture meters to identify any potential condensation points or hidden leaks within that outside wall, which is common in Bur Dubai's older construction.

Post-inspection, the closet must be thoroughly remediated. This isn't just wiping surfaces; it involves HEPA vacuuming all surfaces, abrasive cleaning, and applying an EPA-approved antimicrobial coating to the walls and ceiling to inhibit future growth. Finally, you must implement engineering controls. A small, standalone deshumidifier or a passive ventilation system like a humidity-controlled vent fan is essential to maintain relative humidity below 60%, which is the threshold for mold growth.

Given the value of the items and the potential for hidden issues within the wall cavity, a professional assessment is strongly recommended to ensure the problem is solved permanently.
