Urgent: treat AC mold in kids' room myself?« Back to Previous Page

Given the AC condensation and high humidity in Deira, that wall is likely staying damp, creating a perfect environment for mold. With children experiencing persistent coughing, this situation requires immediate attention.

Do not use bleach. It is mostly water, which can feed the mold roots deep in the porous wall material. The chlorine in bleach only bleaches the surface color away, making it look clean, but it does not kill the organism. More importantly, scrubbing it can release a large number of spores into the air, which your children would then inhale.

For a small, surface-level patch (less than one square foot), you can carefully clean it yourself with a dedicated mold remover or a solution of distilled white vinegar. However, your description of it "spreading from the corner where the AC unit drips" suggests the moisture and the mold itself have likely penetrated the drywall. This is beyond a surface clean. The AC unit itself will also be contaminated and require internal cleaning to stop the cycle.

Given the health symptoms and the hidden moisture source, a professional inspection is strongly recommended. They can use moisture meters to find the full extent of the water damage and conduct air quality tests to identify the spore count and species. In Dubai's climate, the underlying cause—likely the AC drip line or drainage issue—must be fixed first. Otherwise, the mold will return quickly, even after a perfect cleaning. A proper remediation company will contain the area, remove contaminated porous materials like drywall, and use HEPA filtration to clean the air, ensuring spores are not spread throughout your home during the process.
