Can I remove stubborn shower mold myself or need professional?« Back to Previous Page

That's classic bathroom mould, and it's extremely common in Dubai due to our high humidity. The black speckles are likely Cladosporium or Aureobasidium, species that thrive on soap scum and moisture in grout and silicone.

For a small, surface-level patch, you can attempt a DIY treatment. Use a dedicated mould remover containing chlorine-based bleach or hydrogen peroxide—standard bathroom cleaners often lack the required potency. Apply it, let it sit for 10-15 minutes to penetrate, then scrub with a stiff brush. The key is to dry the area completely with a fan or dehumidifier immediately after; just wiping it down won't stop it from returning.

If the mould has penetrated deep into porous grout, reappears within days despite thorough cleaning, or if the musty smell persists, it indicates a more entrenched problem. In such cases, a professional assessment is needed. They can determine if the sealant needs replacement or if there's hidden moisture in the walls. For health safety, especially with infants or anyone with respiratory sensitivities, a lab test can identify the exact species and confirm the airborne spore count is safe.
