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

Based on your description, this is a classic case of mold growth driven by Dubai's high ambient humidity and the specific microclimate created within an enclosed closet. The constant AC use creates a significant temperature differential between the cooled room and the warmer wall, leading to condensation—especially on exterior walls—which is then absorbed by the building materials and dust, providing the perfect food and moisture source for mold spores.

For the remediation, strict safety is paramount. You must wear an N95 respirator, nitrile gloves, and eye protection. Isolate the area by sealing the closet with plastic sheeting. For a small, speckled patch, a solution of detergent (like mild dish soap) and warm water can be effective for non-porous surfaces. Scrub gently with a soft brush, then wipe with a clean, damp cloth. Avoid bleach, as it only removes surface discoloration and does not address the root moisture problem or kill the hyphae (roots) embedded in porous materials like drywall.

However, given that the mold is on a wall and has been present for some time, the hyphae may have penetrated deeply. Simply wiping the surface is often insufficient for a permanent solution. The underlying cause—the condensation and moisture accumulation—must be addressed to prevent recurrence. This requires a professional assessment to identify the exact source, which could be insufficient insulation on an exterior wall, a negative pressure issue, or HVAC-related condensation.

Prevention is key in our climate. Use a dehumidifier or a dedicated desiccant closet dehumidifier unit. Ensure there is adequate air circulation; leaving the closet door ajar can help. Store items in airtight plastic containers, not cardboard boxes.

For a definitive solution and to ensure the health of your indoor environment, I strongly recommend a professional inspection.
