How to clean black mold on closet wall?« Back to Previous Page

Black mold on an interior wall in Dubai is often caused by thermal bridging and condensation, especially on external walls where the building's insulation is insufficient. The dampness you feel confirms this is an active moisture issue.

For a small patch (under one square meter), you can clean it yourself. Wear an N95 mask and gloves. Scrub the area with a solution of white vinegar or a dedicated mold remover, then wipe it dry. Do not use bleach, as it only removes the color and can push the mold deeper into porous surfaces like drywall. Thoroughly dry the area with a fan afterwards. Check your winter clothes; if they are musty or have visible spores, professional dry cleaning is recommended to prevent spreading.

You should definitely call a professional if the mold returns after cleaning, if the affected area is larger than one square meter, or if the drywall feels soft or crumbling, indicating possible internal damage. The constant high humidity here means the root cause—likely a condensation point within the wall—needs to be identified and remedied to prevent recurrence. A professional inspection with moisture meters can pinpoint the exact source of the dampness, which is critical for a permanent solution.
