How to safely remove musty smell from closet?« Back to Previous Page

Based on the symptoms you're describing, particularly the coughing in children, this is a serious indoor air quality issue that needs immediate attention. That persistent musty odor is almost certainly microbial volatile organic compounds (MVOCs) released by active mold growth, which is extremely common in UAE villas after humidity spikes. The closet and your stored items are providing the organic material (dust, skin cells, cellulose in cotton) that the mold is feeding on.

The safest approach is a multi-step process. First, remove all affected items from the closet. Wash all fabrics with a hot wash cycle (if possible) and add white vinegar to the rinse cycle—this is an effective and non-toxic disinfectant. For non-washable items, sunlight is a powerful natural disinfectant; place them in direct sun for several hours.

Next, you must address the source. The high humidity has likely caused condensation within the closet walls or under the flooring, especially if it's an exterior wall. Simply cleaning the surface won't solve it. You need to inspect for hidden moisture. Use a moisture meter to check the walls and floor. A thorough cleaning with a HEPA vacuum followed by an application of a non-toxic, hydrogen peroxide-based antimicrobial solution is crucial to kill the growth at its root.

However, given the health symptoms, I strongly recommend a professional assessment. Hidden mold in the wall cavity can severely impact air quality throughout the room. We use thermal imaging cameras and borescopes to pinpoint the exact moisture source without destructive investigation. DIY solutions often just mask the smell temporarily while the colony continues to grow unseen.
