How to Clean Marble Floors in London: A Homeowner’s Guide

Marble is limestone that has been compressed and heated over millions of years, and it keeps one of limestone’s habits: it reacts to acid. Tile and laminate are sealed, inert surfaces that shrug off most household spills. Marble is different — it is calcium carbonate, and anything mildly acidic, from a squeezed lemon to a splash of wine to many "multi-surface" bathroom sprays, will etch it. The result is not a stain sitting on top that you can wipe away. It is a dull, slightly rough patch where the polished surface itself has been dissolved.

This is the single most common misunderstanding homeowners have about marble floors, and it is why cleaning routines that work perfectly well on every other floor in the house can slowly ruin a marble one.

Yes, and it is worth knowing why. Most of London sits on chalk, which means tap water across the city carries a high mineral content — the same reason kettles and showerheads in London fur up so much faster than in, say, Manchester or Glasgow. On a marble floor, that hard water leaves behind faint white mineral deposits as it evaporates, especially in kitchens and bathrooms where water sits and dries on the surface repeatedly.

On their own, these deposits are just limescale and can usually be lifted with the right approach. The problem is that many people reach for a standard limescale remover to shift them — and those are acidic by design, which etches the marble underneath rather than cleaning it. So the fix for hard water marks and the fix for etching are almost opposites, which is exactly the trap London homeowners fall into.

For day-to-day maintenance, marble is actually low-effort — the routine just needs to stay gentle and consistent rather than reaching for whatever is under the sink.

Most marble damage we are called out to fix in London homes traces back to one of a small handful of habits — usually well-intentioned cleaning that happens to be exactly wrong for this particular surface.

Routine cleaning keeps a marble floor looking its best, but it cannot reverse damage that has already happened, because that damage is physically in the stone rather than on top of it. A few signs are worth knowing, so you can catch a floor before it needs a much bigger job.

Where home cleaning maintains the surface, professional restoration repairs it. This is done mechanically rather than chemically — grinding and honing the top layer back to a flat, even plane using progressively finer diamond abrasives, then polishing it to the finish you want, before sealing it to slow future staining. It is the only way to genuinely remove etching and scratching, because the damaged layer has to be levelled away rather than covered up.

Cost depends on the floor’s area, how deep the scratching and etching go, and the finish you’re after — a lightly dulled bathroom floor and a heavily etched hallway are very different jobs. We quote from photos or a short visit rather than a flat rate, since guessing a number without seeing the floor tends to be wrong in one direction or the other.

What marble floors need tends to vary a little by area, mostly down to the age and style of property. Period conversions in Central and West London often have original marble hallways and fireplaces that have seen decades of wear. Newer developments in East London tend to have marble-look kitchens and bathrooms fitted more recently, where the main issue is protecting the finish rather than restoring old damage.
