Best way to permanently remove shower mold?« Back to Previous Page

First, address the moisture source. Dubai's high humidity and constant AC use create condensation that feeds mold growth. Your window corner is likely a condensation point. Run the exhaust fan during and for 30 minutes after every shower, and wipe down wet surfaces with a squeegee to remove standing water.

For cleaning, local supermarkets carry potent anti-fungal sprays containing chlorine bleach or hydrogen peroxide. Look for brands like Dettol Mold & Mildew Remover. Apply it directly to the grout, let it sit for 10-15 minutes, then scrub with a stiff brush. This will remove surface growth.

Permanent removal is difficult if moisture persists behind the tiles. The black spots often indicate deeper growth in the grout and substrate. If it returns quickly after cleaning, the issue is internal. In such cases, professional assessment is needed to check for moisture penetration and assess if tile regrouting or substrate treatment is required. Companies with microbiological labs can identify the mold type and its penetration depth, which dictates the correct remediation method.

For a long-term solution, consider installing a dehumidifier or improving bathroom ventilation to combat the inherent dampness. Simply cleaning the visible mold will only provide a temporary fix if the room's humidity isn't managed.
