How do I permanently remove mold from my AC closet?« Back to Previous Page

Vinegar only removes surface mold, not the roots (hyphae) deep within porous materials like drywall or shoe leather, which is why the smell and problem return. The AC leak is the primary moisture source that must be fixed first; otherwise, any removal is temporary.

For a situation with visible growth and a persistent smell, professional assessment is strongly recommended. The mold may have spread inside the wall cavity behind the visible patch. A certified inspector can use moisture meters and borescopes to determine the full extent and identify the AC's exact leak point—often a clogged drain pan or disconnected condensate line.

Permanent DIY removal is only feasible on non-porous surfaces. For porous materials like drywall or the shoes, disposal is the safest option. On studs or concrete walls, scrub with a detergent solution, then disinfect with a solution specifically designed for mold remediation. Merely spraying a biocide is ineffective if the moisture issue remains.

To prevent recurrence, the AC unit must be serviced to stop the leak. Afterwards, ensure excellent airflow in the closet; consider leaving the door ajar or installing a vent. A small disposable desiccant dehumidifier can help manage the micro-climate. In Dubai's humidity, any persistent dampness from a leak will always lead to regrowth.
