Care & Maintenance

Six materials, six genuinely different routines.

Generic stone care advice is worse than none, because the correct instruction for soapstone is the wrong one for marble. Below is what each material we fabricate actually needs. The universal rules are short: use pH-neutral cleaners, avoid anything abrasive, use a board rather than cutting on the stone, and use trivets on anything with resin in it.

Marble

Seal on installation and roughly annually. Sealing prevents staining but does nothing about etching, which is a chemical reaction rather than absorption. Wipe acidic spills promptly rather than letting them sit. Clean with pH-neutral products only — never vinegar, never bleach, never a general-purpose spray.

Light etches on honed marble can often be buffed out with a marble polishing powder. Deeper etching on polished marble needs professional re-polishing, which we do. Expect patina over time and choose marble because you like that.

Granite and quartzite

Both are porous and both need sealing on installation and periodically after. Use the water test to decide when: leave a few drops on the surface for fifteen minutes. If the stone darkens underneath, it is time to reseal. If the water beads, do nothing.

Neither etches, so acid is not a concern. Warm water and a pH-neutral cleaner is the whole routine. Both tolerate heat well, though a trivet under a cast iron pan is still sensible on a sealed surface.

Engineered quartz

Never seal it — it is non-porous and sealer will simply sit on the surface. Soap and water handles almost everything; a non-abrasive cleaner handles the rest.

The one real risk is heat. The resin binder scorches and the damage is permanent and not repairable. Always use trivets. Also keep it out of prolonged direct sun, because quartz is not UV stable and will discolour unevenly over time in a bright south-facing room.

Soapstone

Never needs sealing and cannot stain or etch. Clean with anything you like, including products that would ruin marble.

It will scratch and dent. Light scratches sand out with fine sandpaper, and mineral oil evens the colour back afterwards. Apply mineral oil as often as you like the look of it — monthly at first, then whenever the colour looks uneven. Or stop oiling entirely and let it darken at its own pace.

Porcelain and sintered stone

The lowest-maintenance surface available. Non-porous, stain proof, heat proof, UV stable, never needs sealing. Soap and water indefinitely.

The only vulnerability is impact. It is hard but brittle, and a sharp knock to an edge or corner can chip it. Chips cannot be sanded out the way soapstone marks can, so treat edges with a little respect.

What to avoid on everything

  • Vinegar, lemon and any acidic cleaner on natural stone
  • Bleach, ammonia and general-purpose sprays
  • Abrasive pads and scouring powders
  • Cutting directly on the surface
  • Standing hot pans on anything containing resin
  • Leaving standing water on unsealed or overdue stone

We reseal, repair chips and seams, and re-hone or re-polish dulled stone — including countertops we did not originally fabricate. Call 914-575-1705.
