Polished and sealed concrete in a Rosebery studio or showroom

What dulls a polished floor is abrasion. Grit tracked in from outside acts like sandpaper under every footstep, and over months it scratches the surface into a matte finish. Dust mopping before any wet work is therefore the single most important routine task, and it matters more than the mopping that follows. Skipping it and going straight to a wet mop simply grinds the grit around.

That also explains why entry matting is a floor-care item rather than a presentation one. Adequate matting at every entrance removes the abrasive material before it reaches the polished area. On a showroom or studio opening onto a street or a car park, matting does more to protect the finish than any product choice made afterwards. Matting is therefore assessed at the walkthrough alongside the floor itself.

Acidic and strongly alkaline products etch the surface of polished concrete, and the damage is not always visible immediately. It shows as a gradual loss of clarity and reflection that is easy to attribute to age. Bleach, acidic bathroom cleaners, degreasers and general purpose cleaners at the wrong dilution all fall into this category, and they are exactly the products most likely to be reached for by someone unfamiliar with the floor.

That is why the product belongs in the scope by name rather than as a description. A pH-neutral cleaner suited to polished concrete, at a stated dilution, applied with a clean mop and adequate rinsing, is a specification any cleaner can follow. Leaving it as an instruction to use something suitable is how a relief cleaner ends up using whatever is in the trolley. It also gives the occupier something to point at when a new supplier or a relief team asks what may be used on the floor.

Concrete is porous, and sealing reduces that rather than eliminating it. Oil, wine, coffee, ink and anything acidic will stain if left, and the deeper it penetrates the less any cleaning method will retrieve it. Prompt removal is genuinely part of the floor's care rather than a nicety, which means staff dealing with a spill at the time matters as much as the cleaning visit.

Where a stain has set, poultice treatments can sometimes draw it out but the result is uncertain and it is specialist work. More commonly the honest answer is that the mark is permanent until the floor is ground and re-polished. Saying that clearly at the walkthrough sets an expectation that survives the first coffee spill in a showroom entrance. It also encourages staff to deal with spills at the time, which is the only response that reliably works.
