How to safely remove black mold in shower corner?« Back to Previous Page

Black mold in shower corners is common here due to Dubai's high humidity and condensation from air conditioning. For a small patch under one square foot, you can handle it yourself safely. Wear an N95 mask and gloves. Scrub the area with a dedicated mold-killing cleaner containing hydrogen peroxide or a diluted bleach solution (1 part bleach to 10 parts water). Ensure the bathroom is well-ventilated during and after cleaning.

The key to permanent removal is addressing the moisture source. After cleaning, run the bathroom exhaust fan for at least 30 minutes after every shower and wipe down wet surfaces. A squeegee on the walls post-shower helps tremendously. Check for and seal any grout cracks where moisture seeps into the wall.

Given the persistent smell and high humidity, the mold may have penetrated behind the tiles. If the patch is large, returns after cleaning, or the musty odor persists, a professional inspection is warranted to check for hidden growth. In such cases, contact your landlord first. Under Dubai rental law (RERA), landlords are typically responsible for rectifying issues like this that affect the habitability of the property, especially if there's a potential leak or faulty ventilation. They should arrange for proper remediation.
