How to permanently fix AC mold in a Dubai closet« Back to Previous Page

The recurring mold indicates a persistent moisture problem, not just a surface issue. The leak is providing the water, and Dubai's high ambient humidity is providing the spores. Wiping it only removes the visible growth, not the root cause.

First, stop the leak. This is the critical step. You must have a certified HVAC technician repair the AC unit's drain line or condensation pan. Without fixing this, any cleaning is temporary.

For the existing mold, a solution of white vinegar or a dedicated EPA-approved mold cleaner can be used on non-porous surfaces. However, porous materials like drywall, cardboard, or untreated leather shoes may need to be discarded if mold has penetrated, as it's nearly impossible to remove completely. Always wear an N95 mask and gloves during cleaning.

To prevent recurrence after the leak is fixed, you must control humidity. In a small, enclosed closet with an AC unit, condensation is a known issue. Ensure the closet door is left ajar to allow for air circulation from the room. For a more permanent solution, consider installing a small louvered door or ventilation grilles to promote constant airflow. Using a renewable desiccant like silica gel can help, but it's a supplement, not a solution for an active leak.

For a case like this with a known water source and regrowth, a professional inspection is wise to assess any hidden damage within the wall cavity and to confirm the HVAC repair is complete. They can also perform a post-remediation verification test to ensure the spore count has returned to safe levels.
