Can I remove shower mold myself or hire a pro?« Back to Previous Page

Our master bathroom in the Marina apartment has had this musty smell for weeks, but I finally noticed black speckles spreading in the grout between the tiles near the shower. It gets worse because the window is small and the room never fully dries out, even with the exhaust fan. Is this something I can tackle myself with a vinegar spray from the supermarket, or do I need to call in a professional cleaning service to stop it for good?

For minor surface mold on non-porous tile, a DIY approach can be effective. A solution of white vinegar or a dedicated grout cleaner, scrubbed and left to sit, can remove the visible growth. The critical step is addressing the source of moisture; run the exhaust fan for at least 30 minutes after showering and use a squeegee on wet surfaces.

In your Marina apartment, the persistent humidity and lack of drying are the core issues. Given the description of a spreading, recurring problem and a musty smell, the mold may have penetrated the porous grout. DIY methods often only bleach the surface, leaving the root colony intact.

For a lasting solution, a professional assessment is wise. They can determine if the grout needs sealing or replacement and use industrial-grade desiccants to dry the walls out completely, which is crucial in Dubai's climate. A company with a microbiology lab can also test the mold type if there are health concerns, though bathroom mold is typically an irritant. The goal is to fix the drying problem, not just clean what you see.
