How to clean and prevent AC mold in Dubai humidity?« Back to Previous Page

The black spots are likely mold growth caused by condensation from your AC unit's leak, exacerbated by Dubai's high humidity. First, address the leak itself—this is the primary cause. A certified HVAC technician should inspect and repair the unit to stop the moisture source.

For cleaning the visible mold on a hard surface like a wardrobe, a solution of diluted white vinegar or a dedicated mold-cleaning detergent can be effective. Wear an N95 mask and gloves during cleaning. Scrub the area thoroughly, then dry it completely with a fan to prevent immediate regrowth. Porous materials like damaged drywall or insulation may need to be cut out and replaced.

Preventing its return requires controlling humidity and moisture. Ensure your AC is serviced regularly to maintain proper drainage and efficiency, which reduces condensation. Using a dehumidifier in the room, especially during the more humid months, can help keep indoor relative humidity below 60%, a level that significantly inhibits mold growth.

For a persistent issue or if the affected area is larger than one square meter, a professional inspection is strongly recommended. They can use moisture meters and thermal imaging to find hidden dampness and perform lab testing to identify the mold species, which dictates the correct remediation protocol. In many Dubai villas, the problem is not just the visible spot but also mold within the AC unit or wall cavity, which requires specialized equipment to address properly.
