How to treat black and green mold on wall safely?« Back to Previous Page

Black and green speckles behind furniture after condensation are common in Dubai, especially during humid periods when AC use creates temperature differentials. The most effective treatment starts with identifying the moisture source—likely condensation from the temperature difference between the cooled room and the humid air, exacerbated by the wardrobe restricting airflow.

For a small patch (under one square meter), you can clean it yourself. Wear an N95 mask, gloves, and safety glasses. Move the wardrobe away to allow the area to dry completely. Scrub the affected area with a solution of detergent and water. Avoid bleach, as it only removes the colour and doesn't address the root cause. After cleaning, ensure the wall is thoroughly dried. Improving air circulation in the room and maintaining a consistent AC temperature can help reduce future condensation.

However, if the mould covers a larger area, has a musty odour, or has penetrated porous materials like drywall, professional assessment is strongly recommended. Remediation often requires specialised equipment like HEPA vacuums and air scrubbers to properly contain and remove the spores. In many cases, the wall cavity needs to be inspected for hidden growth.

It is not advisable to sleep in the room until the issue is resolved, as mould exposure can cause irritation and allergic reactions, particularly for sensitive individuals. For a definitive identification of the mould type and to verify the cleanup was successful, a post-remediation verification test from an independent microbiology lab is the only way to confirm the space is safe.
