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

Based on your description, this is a classic case of surface mold growth, likely Aspergillus or Cladosporium, exacerbated by the recent high humidity levels in Dubai. The issue is not just on your leather goods but almost certainly within the wall cavity behind the closet, as the exterior wall is a prime location for thermal bridging and condensation when the air conditioning is running.

The most effective approach is a two-phase process: remediation and prevention. For the remediation, do not attempt to clean the leather items with conventional cleaners, as this can set the stains and spread spores. A professional assessment is critical here to determine the extent of the growth within the wall, as this requires specialized containment and removal procedures to prevent cross-contamination. For surface cleaning on non-porous shelves, a solution of detergent and water can be used, but biocides are regulated in the UAE and should only be applied by certified professionals to ensure they are used safely and effectively.

For permanent prevention, the root cause must be addressed. This involves identifying and rectifying the source of moisture. The culprit is likely condensation forming on the cooler exterior wall. Solutions include improving ventilation within the closet, ensuring your AC system is properly balanced to manage humidity (ideally maintaining indoor levels below 60%), and potentially installing a vapor barrier or improving insulation on that specific wall to prevent the thermal difference.

Given that the mold is already affecting stored items and you suspect wall infiltration, a professional inspection is strongly recommended. Our certified team at Saniservice uses thermal imaging cameras to pinpoint moisture sources and conducts air and surface sampling to identify the spore types and concentration, which dictates the correct remediation protocol. We are fully compliant with Dubai Municipality's environmental health and safety standards.
