Is black mold causing allergies and how to clean safely?« Back to Previous Page

Black mold in your closet is very likely causing your husband's morning congestion and itchy eyes. The high humidity we've had recently creates ideal conditions for mold growth, especially on exterior walls where temperature differences can cause condensation. In Dubai's climate, this is a common issue in poorly ventilated spaces like closets.

For a small patch (less than one square meter), you can clean it yourself with proper precautions. Wear an N95 mask, gloves, and eye protection. Scrub the area with a mixture of white vinegar and water or a mild detergent. Avoid using bleach, as it doesn't kill the mold roots and can worsen indoor air quality by releasing fumes. Ensure the area is well-ventilated during and after cleaning.

The real solution is to address the moisture source. Since it's on an exterior wall, the problem is likely persistent condensation from the temperature differential between your air-conditioned room and the humid outside air. Improving ventilation in the closet is crucial; leaving the door ajar or installing a small vent can help. Using a dehumidifier in the bedroom during humid periods can also prevent recurrence.

If the mold covers a larger area, has a strong musty odor, or returns quickly after cleaning, a professional inspection is recommended. They can identify the exact moisture source and species of mold, which is important for determining the appropriate remediation strategy, especially if it is one of the less common but more problematic types. For rental properties, this is also the point to involve your landlord, as structural moisture issues are typically their responsibility to fix.
