How to remove black mold near AC vent in Dubai?« Back to Previous Page

That black patch near your AC vent is a classic sign of condensation issues, very common in Dubai's climate. The constant AC use creates a cold surface on the wall, and when it meets the humid outdoor air, moisture forms and mould grows.

For a small patch (under one square foot), you can address it yourself. Wear an N95 mask, gloves, and safety glasses. Scrub the area with a mixture of water and detergent or a dedicated mould remover. Dry the area completely immediately after cleaning. However, since it's spreading and you note a damp feeling, the underlying moisture problem is likely still active. Simply cleaning the visible mould won't stop it from returning.

This situation often requires a professional assessment. The most effective approach is to identify and stop the moisture source. A certified inspector can use a thermal imaging camera to find the exact point of condensation or a potential leak within the AC system itself. In many cases, improving the room's insulation or having an HVAC technician rebalance the system to prevent overcooling that specific surface is the permanent solution. For confirmed Stachybotrys (true "black mould"), professional remediation with containment is the standard industry practice to safely remove it.
