To clean it safely, never dry brush or use bleach, as this can aerosolize spores. For a small patch (under one square meter), wear an N95 mask and gloves. Scrub the area with a mixture of detergent and water, then wipe with a diluted vinegar solution. Dry the area completely with a fan. However, since the mold is black and symptoms are present, a professional inspection is strongly advised to identify the species, as some types common here, like Aspergillus, require more stringent containment protocols for safe removal.

To prevent recurrence, you must address the moisture. Move the wardrobe at least 15cm away from the wall to allow air circulation. Identify if the wall feels colder than others; this is a thermal bridge where condensation forms. Improve room ventilation by using an exhaust fan or opening windows when outdoor humidity is lower. Ensure your AC unit is serviced and draining properly, as a clogged drain pan can contribute to indoor humidity. For a long-term solution, consider having the wall’s insulation checked, as this is often the core issue in Dubai’s climate where exterior walls can become condensation magnets.
