Black shower grout mold: clean myself or call pro?« Back to Previous Page

That sounds like a classic case of mould growth in a high-humidity, low-ventilation area. In Dubai's climate, this is extremely common due to condensation from hot showers and year-round AC use creating persistent dampness.

For a small, surface-level area, you can attempt to clean it yourself. Use a dedicated grout cleaner or a paste of baking soda and white vinegar. Scrub with a stiff brush, then rinse thoroughly. The key is to dry the area completely afterward with a towel and a fan; simply letting it air dry won't suffice.

However, if the mould reappears quickly after cleaning, if the grout feels soft or crumbly, or if the staining is extensive and dark, it indicates deeper infiltration. In these cases, a professional inspection is warranted to assess if the moisture has penetrated behind the tiles. A certified inspector can use moisture meters to determine the extent and recommend remediation, which may involve regrouting or addressing underlying leaks. This is crucial to prevent structural damage and potential health issues from prolonged spore exposure.
