How to treat black mold on bedroom wall myself?« Back to Previous Page

Black mold growth behind furniture is common in Deira due to high humidity and restricted airflow from the AC. Your situation likely involves condensation buildup, exacerbated by the recent humid weather and a potentially underperforming AC unit.

For a small, contained area (under one square meter), you can attempt to clean it yourself. Wear an N95 mask, gloves, and safety glasses. Mix a solution of one part white vinegar to four parts water or a diluted detergent. Scrub the area thoroughly, then dry it completely with a fan. The key is not just cleaning but eliminating the moisture source. Ensure your AC is serviced and set to a consistently low humidity level, and improve air circulation around the wardrobe.

However, if the mold covers a larger area, has a strong musty odor, or has penetrated through the wall, this indicates a more serious moisture issue within the wall cavity. DIY cleaning will only address the surface and it will return. In such cases, a professional inspection is necessary to identify the root cause—such as a hidden pipe leak or condensation within the AC ductwork—and to perform remediation that includes containment and air scrubbing to prevent spore dispersal. For verification, a company with its own microbiology lab can provide a species identification report to confirm the type of mold present.
