How to prevent mold in cold closet every winter?« Back to Previous Page

That's a classic Dubai condensation problem. Your closet's exterior wall is likely a thermal bridge, becoming much colder than the room. When humid air enters the closet and hits that cold surface, it condenses, creating the damp environment mold needs. Running the AC lowers overall humidity but doesn't address this localized cold spot.

First, remove all affected items and clean the closet with a solution of white vinegar or a dedicated mold-cleaning product. Allow everything to dry completely. For the leather goods, a professional cleaner experienced with mold is your safest bet to prevent damage.

To prevent recurrence, you need to manage both humidity and temperature differentials. Keep the closet door open as often as possible to allow conditioned air to circulate inside and equalize the temperature with the room. If possible, move your leather items to a less vulnerable location during the winter months. A small, renewable desiccant dehumidifier (like silica gel packs) placed inside the closet can help absorb excess moisture passively.

For a more permanent solution, improving air circulation is key. A small, battery-operated moisture absorber with a fan can make a significant difference. In severe or persistent cases, the underlying issue might be insufficient insulation within that wall cavity, a common finding in older villas. A professional inspection can identify these thermal bridges and recommend targeted remediation, which is often the only way to solve the problem for good.
