How to remove and prevent black mold in Dubai apartment?« Back to Previous Page

Black mold in Dubai is a common issue due to the high ambient humidity and the constant temperature swings from AC. The small black spots in your closet are likely Cladosporium or Aspergillus, which thrive in stagnant, humid air. The wall corner is a classic cold spot where condensation forms, providing the moisture mold needs even with the AC running.

For cleaning small, surface-level growth, wear an N95 mask and gloves. Use a solution of white vinegar or a dedicated mold-cleaning product. Do not use bleach, as it only removes the colour and can push the roots deeper into porous surfaces like drywall. Scrub the area gently, let it dry completely, and then monitor it. If the spots return within a week, the moisture issue is unresolved or the growth has penetrated the wall.

Prevention is more critical than cleaning. Lower the humidity in that closet by ensuring air can circulate; leave the door ajar or use a small desiccant dehumidifier. Check if your AC is set too high; a very cold setting can cause more condensation on walls. For a lasting solution, identify and address the moisture source. In many older Dubai buildings, this can be a slight leak in the AC condensation drain line within the wall or insufficient insulation.

If the area is larger than one square foot, the spots return quickly after cleaning, or you notice a musty smell, a professional inspection is advised. They can use moisture meters and thermal imaging to find hidden condensation points and take air or surface samples for lab analysis to confirm the mold type. Remediation then focuses on fixing the moisture problem first, before any cleaning or sealing of surfaces.
