Mold behind toy chest causing kids' cough? How to clean safely?« Back to Previous Page

That mold is very likely contributing to their coughs. The damp, cool conditions behind the toy chest next to the AC vent are a perfect breeding ground. In Dubai's climate, AC units create significant condensation, and if the room's humidity isn't controlled, this moisture leads to mold growth on cooler surfaces like exterior walls. The black fuzzy appearance suggests a significant colony that is releasing spores into the air they breathe at night.

For their safety, move the toys and the chest to another room immediately and increase ventilation by opening windows when outdoor humidity is low, typically early morning. Do not attempt to clean it with bleach or by scrubbing, as this can aerosolize a high concentration of spores. For a small patch (under one square foot), a solution of distilled white vinegar can be lightly sprayed to dampen and inhibit growth, but this is only a temporary measure.

The safest approach is to have a professional inspection. They can identify the moisture source—often a poorly insulated wall causing condensation or a slight AC drain issue—and take samples to identify the mold type, which dictates the proper remediation protocol. This is crucial with children involved, as some species are more problematic than others. Remediation involves containing the area with plastic sheeting, using HEPA filtration to capture spores, and safely removing the contaminated material. Always verify that the company provides before-and-after lab reports to confirm the spore count has been returned to safe levels.
