How to remove mold from closet on interior wall?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots appearing on the back of our bedroom closet, which is on an interior wall in our Jumeirah apartment. It's been extra humid lately and I'm worried it's spreading. What's the most effective way to get rid of this mold for good without having to call in a super expensive professional team right away?

First, isolate the area by closing the closet door to prevent spores from dispersing into the room. Wear an N95 mask and gloves for protection. The black spots are likely surface mold feeding on dust and organic material in the high humidity.

For a small area, a solution of white vinegar or a diluted bleach mixture (1 part bleach to 4 parts water) can be effective. Apply it with a cloth, scrub gently, and allow the surface to dry completely. In Dubai's climate, the root cause is almost always excess moisture. An interior wall suggests condensation from poor air circulation or a hidden leak from adjacent plumbing.

After cleaning, address the humidity. Improve ventilation by leaving the closet doors ajar and using a dehumidifier or a desiccant bag inside. Ensure your AC is running efficiently, as it is your primary dehumidification tool. If the mold returns quickly, the issue is persistent moisture or the growth may be deeper within the wall.

For a problem that recurs or covers more than a square foot, a professional inspection is recommended to identify the moisture source and assess the extent. In many cases, DIY cleaning only addresses the surface, not the root cause. Companies like Saniservice use moisture meters and borescopes to diagnose hidden problems and can provide a lab analysis to identify the mold type, which dictates the correct remediation protocol. For persistent issues on an interior wall, calling 800-MOLDS for a diagnosis can prevent a larger, more costly problem later.
