How to safely remove and prevent black carpet mold?« Back to Previous Page

The damp feel and black carpet growth in a Dubai bedroom, even with AC running, is a classic sign of condensation-related mould. The AC may be set too cold, causing the unit to short-cycle and not adequately remove humidity, or there could be a specific moisture source like a slow leak.

For a small, visible patch (under one square meter), you can clean it yourself with caution. Wear an N95 mask, gloves, and goggles. Never use bleach, as it doesn't kill mould roots and can worsen indoor air quality. Instead, use a dedicated mould remover or a solution of white vinegar and water. Scrub the area, then dry it completely within 24-48 hours using fans and a dehumidifier. This is critical in our humid climate.

However, mould on carpet often means it has penetrated the backing and possibly the underlay and floor beneath. Surface cleaning will not remove this hidden reservoir, which is likely contributing to your children's coughing. The most effective and safe approach is professional remediation. They will isolate the area, use HEPA vacuums, and may need to remove and dispose of the carpet and underlay to properly address the root cause.

To prevent recurrence, identify the moisture source. Have your AC unit inspected; it may need servicing to improve its dehumidification function or a adjustment to the thermostat setting. Consider using a standalone dehumidifier in the room, especially during the more humid winter months. Improving air circulation with fans can also help. For a definitive answer on the mould type and its potential health impacts, a lab test from an indoor health company can provide clarity and guide the necessary remediation steps.
