Can I clean mold from my wall myself?« Back to Previous Page

For the small black spots you're describing, a DIY approach can be effective if the affected area is small (less than one square meter) and the mold is only on a non-porous surface like painted drywall. In Dubai's high humidity, the root cause is almost always the AC leak, so fixing that is the critical first step. Turn off the AC unit to the bedroom and have the leak repaired immediately to stop the moisture source.

To clean, never use bleach. It is mostly water, which feeds mold growth, and its fumes are hazardous in enclosed spaces. Instead, use a dedicated fungicidal cleaner or a simple solution of distilled white vinegar. Scrub the area thoroughly, then dry it completely with a fan or dehumidifier within 1-2 hours to prevent immediate regrowth.

However, given your description—a spreading area, a persistent damp feeling, and a distinct musty odor—this suggests a more established problem. The moisture from the leak has likely penetrated the wall, allowing mold to grow inside the cavity where you cannot see or effectively clean it. Scrubbing the surface spots will not address this hidden colony, which will continue to release spores and cause the smell. In such cases, a professional inspection is strongly advised to assess the full extent. They use moisture meters and borescopes to see inside walls and can determine if sections of drywall need replacement. For health safety, especially in a bedroom, a proper remediation protocol is necessary to ensure the problem is resolved at its source.
