How to permanently remove hidden mold in a humid bedroom?« Back to Previous Page

The hidden mold behind your wardrobe is a classic symptom of Dubai's high humidity, where AC units often struggle to remove enough moisture from sealed rooms. The most effective approach is a two-step process: first address the existing growth, then correct the moisture source to prevent its return.

For the visible patch, a solution of white vinegar or a dedicated mold remover can be applied to clean the wall surface. However, hidden mold often means a larger colony within the wall cavity. Simply wiping the surface often leaves the root system intact, allowing it to regrow. For a permanent solution, the affected section of drywall may need to be carefully removed and replaced by a professional to ensure all contaminated material is gone.

Stopping it from coming back requires fixing the humidity. Your constantly running AC may be set too cold, causing the coil to freeze and reducing its ability to dehumidify. Try raising the thermostat a degree or two. The real issue is likely insufficient air circulation behind the wardrobe; moving it a few inches away from the wall is crucial. Consider using a standalone dehumidifier in the room, especially during the more humid winter months, to maintain humidity below 60%.

For a situation like this in a bedroom, a professional inspection is recommended to assess the full extent behind the walls and to identify any HVAC issues contributing to the dampness. They can use moisture meters and thermal cameras to find hidden dampness you can't see.
