How to remove and prevent mold in a low-airflow bedroom?« Back to Previous Page

The black spots behind the wardrobe are a classic sign of condensation mould, extremely common in Dubai's low-airflow rooms. The combination of high ambient humidity and a cold exterior wall from constant AC use creates the perfect damp environment for mould to grow unseen.

For removal, first address the moisture source. Move the furniture away from the wall to allow air circulation. To kill the existing mould, wear an N95 mask and gloves. Clean the area with a solution of white vinegar or a dedicated mould remover, not bleach, as bleach only removes the colour and does not kill the spores at the root. Scrub the wall thoroughly and allow it to dry completely.

Preventing its return is the critical part. You must improve air movement in that corner. Consider leaving a small gap between the wardrobe and the wall. A small, discreet dehumidifier can work wonders in a bedroom corner to pull excess moisture from the air. For villas in Mirdif, ensuring your AC unit is serviced and its drain lines are clear is vital to prevent humidity buildup.

If the affected area is large (generally over one square meter) or the coughing persists after cleaning, a professional inspection is recommended. They can use a moisture meter to identify any hidden dampness within the wall itself and take air or swab samples for lab analysis to identify the mould species, which is important information if health symptoms continue.
