How to permanently remove closet mold in humid weather?« Back to Previous Page

That leak and the resulting mold growth are a common but serious issue in Dubai's climate. The high humidity and constant AC use create perfect conditions for mold to thrive, especially in enclosed spaces like closets.

First, address the source. The AC leak must be repaired by a qualified HVAC technician. No amount of cleaning will stop the mold from returning if the moisture source isn't fixed.

For the existing mold, surface cleaning is a temporary measure. On non-porous surfaces like metal or plastic, a solution of detergent and water can remove visible growth. For porous materials like drywall or the back of a wooden wardrobe, the mold often penetrates deep into the material. Scrubbing the surface will not remove the root structure, and it will almost certainly return. In many cases, the affected drywall and insulation must be carefully removed and discarded.

Given the strong smell and spread you describe, this is likely beyond a DIY fix. The mold colony is established and releasing spores. Proper remediation involves isolating the area to prevent cross-contamination, using HEPA filtration to capture airborne spores, and removing all contaminated materials. After removal, the underlying area must be treated and dried completely with professional-grade equipment before any rebuilding.

To prevent recurrence, ensure the closet has adequate ventilation. Leave space between the wall and your clothes, and consider a small desiccant dehumidifier or moisture absorber for that enclosed space. Keeping the AC running consistently helps control whole-home humidity.

For a case like this, a professional inspection is strongly recommended to assess the full extent of the damage behind the walls. They can provide a protocol for safe, permanent removal and post-remediation verification to confirm the problem is truly resolved.
