What's the safest way to clean kids' bedroom mold?« Back to Previous Page

My kids have been coughing and I suspect it's from black mold growing around the window in their bedroom. We first noticed the small black spots after the heavy dew last month, but it’s spread into a bigger patch on the wall. What’s the safest and fastest way to clean this myself before it affects their health even more?

The safest way to clean a small patch of mold in your kids' bedroom starts with safety gear. Wear an N95 mask, gloves, and eye protection to avoid inhaling spores or getting them on your skin.

For a patch that has spread, mix a solution of one part white vinegar with four parts water. Do not use bleach, as it only removes the surface discoloration and can leave moisture behind, allowing the mold to regrow from the roots. Lightly spray the solution onto the affected area and let it sit for an hour before scrubbing with a stiff brush. Wipe the area clean with a damp cloth and ensure it is completely dried. In Dubai's climate, use a dehumidifier or the room's AC on a dry setting to remove all moisture from the air; this is critical to prevent immediate regrowth from our high humidity.

However, cleaning only addresses the visible growth. The underlying cause is almost certainly condensation from the temperature difference between the cold AC and the humid outdoor air seeping around the window frame. Until that moisture source is sealed, the mold will return.

Given that your children are already showing respiratory symptoms like coughing, a DIY cleanup may not be sufficient. Disturbing the patch can aerosolize a high concentration of spores directly into their bedroom air. For health-sensitive situations and to identify the exact mold type, a professional inspection and possibly lab testing of a surface sample is the most reliable course of action. They can confirm if it's a common allergen-producing mold or something that requires more extensive containment procedures.
