How to remove mold nad prevent its return in humid climates?« Back to Previous Page

Mold on curtains in a sea-facing Jumeirah apartment is a classic symptom of condensation from the high humidity and temperature differential between the cool indoor air and the warm, humid exterior wall. The constant AC use creates cold surfaces where moisture condenses, providing the perfect environment for mold growth.

For removal, take the curtains down and wash them at a high temperature (60°C or above) if the fabric allows. For the wall behind them, scrub the affected area with a diluted detergent solution or a mixture of white vinegar and water. Avoid bleach, as it only removes the colour and does not kill the root structure of the mold. Wear an N95 mask and gloves during cleaning to avoid inhaling spores.

Preventing its return requires addressing the moisture source. The wall is likely a "cold bridge," where the outside heat meets your cooled interior, causing condensation. Improve air circulation immediately by moving the curtain rail a few inches away from the wall and leaving a gap between the back of the curtains and the wall. Wipe down windows and walls in the area regularly to remove condensation. Consider applying an anti-mold primer to the wall before repainting to create a protective barrier.

For a persistent issue, a professional assessment can identify the exact cause. They can perform a thermographic scan to pinpoint the cold spots in the wall and recommend solutions, which may include improving the wall's insulation or the seal around the window. In many Dubai apartments, this is a recurring structural issue that requires targeted intervention beyond surface cleaning.
