What's the best mold remover in the UAE's humidity?« Back to Previous Page

The most effective approach for mold under silicone sealant is complete removal and replacement, not just surface treatment. For surface mold on grout, chlorine-based bleach solutions (like Clorox) diluted 1:10 with water are effective, but only on non-porous surfaces. For porous grout, the mold's roots often remain.

In Dubai's high humidity, mold will return unless you fix the moisture source. Bathrooms need constant ventilation; run the exhaust fan for 30-60 minutes after every shower. Wipe down wet walls and tiles to remove condensation. A dehumidifier can help if the smell persists.

However, discovering extensive growth under sealant is a significant red flag. This indicates persistent moisture intrusion, likely from a failing seal or a leak behind the tiles. Surface cleaners are a temporary fix here. The silicone must be fully removed, the area underneath professionally dried, treated with a antimicrobial solution, and then resealed with a high-quality mold-resistant silicone, which is available at most major hardware stores.

For a rental in a high-rise like Marina, document everything with photos and notify your landlord or property management company immediately. They are typically responsible for remediation that involves structural elements like sealant and potential leaks behind tiles. DIY attempts on this scale could inadvertently cause more damage and affect your deposit. If the musty smell permeates the apartment or anyone experiences respiratory irritation, a professional inspection is advised to assess the full extent.
