What's a safe way to clean bathroom mold?« Back to Previous Page

My kids have been coughing more than usual, and I just found black spots growing behind the toilet in our master bathroom. It's a windowless bathroom in our apartment in Jumeirah, and the humidity has been terrible since the weather changed. What's the safest way to clean this myself without using harsh chemicals that could affect my family?

For a small patch of mold in a bathroom, a solution of distilled white vinegar is often effective and safe for households with children. Spray it undiluted onto the mold, let it sit for an hour, then scrub with a brush and rinse. For persistent spots, a paste of baking soda and water can provide extra abrasive power without harsh chemicals. Always wear a mask and gloves during cleaning to avoid inhaling spores.

The underlying issue in a windowless Dubai bathroom is constant high humidity. After showering, run the exhaust fan for at least 30 minutes and wipe down wet surfaces. A dehumidifier or a moisture-absorbing product like silica gel can help maintain lower humidity levels between uses. This is crucial, as cleaning only removes existing mold without addressing the moisture that allows it to return.

If the mold covers an area larger than one square meter, returns quickly after cleaning, or is in the HVAC system, a professional inspection is warranted. In such cases, surface cleaning isn't enough, and the mold may have spread into walls or behind tiles. A certified inspector can use moisture meters and thermal imaging to find the hidden source of moisture and take samples for lab analysis to identify the specific mold type, which is important if health symptoms are a concern.
