Clean soapstone countertops with warm water, a few drops of mild dish soap, and a soft cloth or nonabrasive sponge. Wipe the whole area, remove the soap with a clean damp cloth, and dry it to prevent streaks. Do not scrub with steel wool or a harsh abrasive: soapstone resists heat and many chemicals, but it is softer than granite and can scratch.
Daily cleaning in four steps
- Lift crumbs and grit instead of dragging them across the surface.
- Wipe with warm, lightly soapy water and a clean soft cloth.
- Use a second damp cloth to remove cleaner residue.
- Buff dry with a towel, especially around the sink and seams.
The Natural Stone Institute recommends a neutral stone cleaner, stone soap, or mild liquid dishwashing detergent with warm water for routine natural-stone care. Too much soap can leave a film, so use a small amount and rinse it away.
What to do with dried food or grease
Lay a warm damp cloth over dried residue for several minutes, then lift it with a plastic scraper held nearly flat. Follow with mild soap and water. For an oily ring, clean the entire affected area rather than rubbing only the center; spot cleaning can make the surrounding patina look uneven even when the stone itself is clean.
Does soapstone need mineral oil?
Mineral oil is usually an appearance treatment, not a requirement for everyday cleaning. It darkens the stone and can make the developing patina look more even. Soapstone fabricators differ on schedules, so follow the installer that supplied your slab. Bucks County Soapstone, for example, says oiling frequency is a matter of the preferred light-gray or dark appearance rather than one fixed schedule.
- Clean and completely dry the countertop.
- Test the oil or wax in an inconspicuous place.
- Apply a very thin, even coat of a food-contact-appropriate product recommended by the fabricator.
- Buff away all excess with a clean cloth so the counter does not feel greasy.
Do not use cooking oils such as olive or vegetable oil. They can become sticky or rancid. If the counter has a manufacturer-applied treatment, follow that product’s instructions instead of layering a different finish over it.
Scratches, pale marks, and stains
A pale line may be a scratch through the darker patina rather than a stain. Very fine scratches can sometimes be blended with guidance from the fabricator, followed by re-oiling the affected area. Do not start sanding an installed countertop blindly: grit, finish, edge details, and seam placement matter. Deep gouges, chips, cracks, or damage near a seam belong with a stone professional.
What not to use
- Steel wool, gritty scouring powder, or an abrasive cleaning pad
- A metal scraper or knife used as a cleaning tool
- More concentrated cleaner than its label specifies
- A random sealer or oil without checking the fabricator’s instructions
- A mixture of cleaning chemicals—particularly bleach with ammonia
Soapstone is not quartzite. If you are unsure which stone you own, ask the installer before applying a treatment. Our quartzite cleaning guide uses a more conservative approach to acids and sealers.
