How to prevent AC condensation in wardrobe?« Back to Previous Page

The black spots are likely mold caused by condensation, a common issue in Dubai due to the high humidity and constant AC use. When the cold air from the AC directly hits the warmer wall inside the wardrobe, it drops the surface temperature below the dew point, causing moisture to form.

First, improve air circulation. Keep the wardrobe doors slightly ajar to allow room air to mix with the air inside, preventing stagnant, humid pockets. Ensure the room's AC vents are not blowing directly onto the wardrobe; adjust the louvers to diffuse the air flow across the room instead of in a concentrated stream.

Next, address the room's humidity. Run a dehumidifier in the bedroom, especially during the more humid winter months, to keep relative humidity below 60%. Consistently running your AC on "dry" or "auto" mode also helps remove moisture from the air.

For a more permanent solution, consider insulating the back wall of the wardrobe. Applying a thin layer of foam board insulation can create a thermal barrier, preventing the cold AC air from chilling the wall surface and forming condensation.

Since the mold has returned after cleaning, the spores are established. Wiping with a vinegar solution can help, but the underlying moisture issue must be solved to prevent recurrence. If the problem persists or the affected area is large (over one square meter), a professional inspection can identify the exact moisture source and mold type to determine the most effective remediation strategy.
