Benchtop polishing: what the service actually does.
Benchtops never wear evenly. Cloudy by the sink, scratched at the island edge, dull where people lean. A wipe does nothing for any of that, and neither does a shine spray. Here is what does.
Polishing a benchtop is not adding shine on top. It is refining the stone's own face with abrasives until the damage is gone and the finish is even, then protecting it. The order matters more than the products.
Identify the stone
Marble, limestone, travertine, granite, terrazzo and engineered stone each want a different sequence, and surfaces are misidentified more often than you would think. Marble treated like granite, or engineered stone treated like natural stone, gives a poor result and real risk. So the first step is confirming what the top is, what finish it has, what has been put on it before, and what is wrong: scratches, etching, dullness, stains, chips.
Clean, then look again
Polishing over grease, mineral deposits or soap film compromises the result and hides the true condition. The top is cleaned with stone-safe products first, which is often when the real extent of the scratching or the outline of a stain shows.
Hone out the damage
Scratches and etch marks live in the top fraction of a millimetre. Honing with fine diamond abrasives takes that layer off evenly. Light marks need a minimal pass; deeper scratches need more, and on a benchtop there is a limit, because the edges, the thin sections and the veining should not be ground away to chase one line. A scratch the fingernail catches is softened and blended rather than erased, and that is said before the work, not after.
Polish to the finish it had
Then the surface is taken back through progressively finer stages: to a reflection on a polished top, to an even satin on a honed one. Matching is the skill. A polished finish has to reflect evenly across the whole restored area; a honed one has to look refined, not patchy or accidentally glossy. This is also why a spot repair on a glossy top usually looks worse than the scratch: one bright patch in a slab of even reflection. If marks are in several places or the whole top has dulled, the whole top is done.
Edges and chips
Chips at the sink cut-out and the island corners are filled with a colour-matched material before honing, so the repair is refined with the surface rather than after it. A good repair is discreet in normal use and is not completely invisible under close inspection of a heavily veined stone.
Seal
A penetrating sealer finishes the job. It slows oil and wine getting in; it does not make the top acid-proof or scratch-proof, so lemon juice will still etch it and a dragged pot will still mark it.
Which finish
Gloss shows depth and pattern and also shows fingerprints, water spots and the next etch. Honed is forgiving and suits a working kitchen. Satin sits between. It is a conversation to have before the abrasives come out, because the finish is chosen, not applied.
After the work the routine is a neutral cleaner, spills wiped when they happen, boards and trivets, and a periodic water test for the sealer. Most tops are a single visit, done on the bench with the kitchen protected.

Can etched marble be restored, or does it need replacing?
Etched marble can be restored in place, and replacement is almost never the right answer. Etching is a thin layer of the polished surface dissolved by acid. It is not a stain and it does not go deep. The mark is honed off with diamond abrasives and the area is re-polished to match the rest of the top. On a benchtop that is usually a couple of hours of work, done on the bench with the kitchen protected. Deep etching that has left a visible dip takes more honing and blends less perfectly, and that is exactly the sort of case we cut a test patch for before committing. Replacing a benchtop means a new slab, templating, fabrication, removal, plumbing and a splashback, and weeks without a kitchen. Restoring it is a fraction of that.
How soon can I use my benchtop after it is restored?
Soon after, and we tell you exactly when before we leave. The polishing itself leaves the surface ready to use immediately. What needs time is the sealer, which is applied last and needs to cure before the stone is exposed to water and oil. For most penetrating sealers that is a few hours to overnight, and we tell you the exact window before we leave. Light use, like putting the kettle on, is fine straight away. Chopping, spills and hot pans should wait until the sealer has cured. We leave a short care card on the bench with the cleaners that are safe on sealed stone and the ones that will undo the work.
Will a chip repair be invisible?
On a plain stone, close to it. On a heavily veined marble, no, and we would rather say so than surprise you. A chip is filled with a colour-matched resin, shaped to the edge profile and polished with the surrounding stone, so it is smooth, durable and the right colour. What it cannot do is reproduce the veining running through it, so on a stone like Carrara or Arabescato the repair reads as a small plain patch from close up. From standing height it disappears. We show you the result on the first repair before doing the rest, and if the visibility bothers you there are alternatives, including a small edge profile change that removes the chip rather than filling it.
