How to clean closet mold from AC leak?« Back to Previous Page

The black spots indicate active mold growth, which is common here due to AC condensation leaks combined with Dubai's high humidity. For a small area (under one square meter), you can clean it yourself. Wear an N95 mask, gloves, and eye protection. Scrub the area with a mixture of detergent and water, then disinfect with a solution of one part household bleach to ten parts water. Let it dry completely with the closet door open and a fan running.

The most critical step is fixing the source. The AC drain line is likely clogged or the drain pan is cracked. This is a recurring issue in our climate with year-round AC use. DIY cleaning only addresses the visible growth; hidden mold inside the wall or AC unit is a strong possibility.

For the AC repair, you need a certified HVAC technician to clear the drain line, check the condensate pump, and ensure the unit is properly sealed. To confirm the mold is fully resolved, a professional inspection with moisture mapping is recommended. They use thermal cameras to find hidden dampness and can take air or surface samples for lab analysis to identify the spore types and concentrations, which is the only way to verify the space is truly safe.
