How to treat mold in closet and stop it spreading?« Back to Previous Page

That black spot pattern on clothing is a classic sign of a high-moisture environment, and your timing makes sense. The recent high humidity and dew in Jumeirah create significant condensation on exterior walls, which then soaks into the closet from the inside.

First, address the immediate items. Take the moldy clothes outside to brush off the spores. Then, wash them in hot water if the fabric allows, adding white vinegar or a mold-killing additive to the cycle. Sun-drying is highly effective. For dry-clean-only items, inform the cleaner about the mold specifically.

To treat the closet itself, empty it completely. Mix a solution of one part white vinegar to four parts water or a diluted bleach solution (wear gloves and ensure ventilation) and thoroughly wipe down all surfaces – walls, shelves, and the floor. Let it dry completely with the closet doors open and a fan circulating air. A portable dehumidifier placed in the room for a few days will pull excess moisture from the air.

The potential for spread into the wall cavity is a real concern here. Closets on external walls are common condensation points because the cold from the AC meets the warm, humid air. The mold you see on the clothes is likely just the visible part. It can be growing on the back of the drywall or on the insulation, which you cannot access.

For a situation that returned after weather changes, a professional inspection is strongly advised. They use moisture meters and borescopes to check inside the wall. If the wall is compromised, surface cleaning alone won't solve it, and the mold will return. The Dubai climate means this is an ongoing battle; the goal is to identify and control the moisture source, which often requires building envelope remediation.
