Marble, porcelain and the expensive ways to clean a floor wrong
A large share of UAE homes — especially older Dubai and Abu Dhabi stock — have real marble floors, and marble is calcium carbonate: anything acidic etches it permanently. Vinegar, lemon-based cleaners and most supermarket limescale removers leave dull cloudy patches no mopping fixes. Restoring etched marble means grinding and repolishing at roughly AED 15–40 per square metre, so one wrong bottle used across a 100-square-metre flat can create a four-figure repair. If your floors are marble, insist on pH-neutral cleaner and say so at booking.
Unsure what you have? Marble is cool to the touch with veining that runs irregularly, and no two tiles match; porcelain repeats its pattern. When a cleaning company asks about your floor type before quoting, that is a quality signal. When they never ask, that tells you something too.
