what's the best supermarket mold remover for bathroom grout?« Back to Previous Page

Look for a chlorine-based bleach spray, like a thick gel version designed for grout. Brands like Clorox or local equivalents are widely available. The key is application: spray it on, let it sit for 10-15 minutes to penetrate, then scrub with a stiff brush. This kills surface mould effectively.

However, in Dubai's climate, bathroom mould is rarely just a surface issue. The high humidity and constant AC use create condensation within the walls, allowing mould to grow deep behind the tiles. A strong smell indicates a more significant moisture problem. Supermarket products are a temporary fix; the mould will almost certainly return if the underlying moisture isn't resolved.

For a recurring problem, the most effective solution is identifying and fixing the moisture source, which could be a leaking pipe behind the wall or insufficient ventilation. A professional inspection using a moisture meter can pinpoint the exact cause. For definitive identification of the mould type, a lab test is the only method.
