Common Mistakes to Avoid When Cleaning Soapstone Countertops
Soapstone is uniquely low-maintenance, but common cleaning mistakes can still damage it. Learn what NOT to do—and the right approach—from professional stone care experts.
Soapstone is one of the most forgiving natural stones for countertops—it's non-porous, doesn't etch from acids, and doesn't need sealing. But that doesn't mean it's indestructible. Soapstone has its own unique characteristics (it's softer than granite, develops a natural patina, and scratches more easily) that require a tailored care approach. At Granite Heroes, we see homeowners making the same soapstone mistakes repeatedly. Here are the most common errors and how to avoid them.
1. Don't use abrasive cleaners or pads
Soapstone ranks 1–2 on the Mohs hardness scale—softer than your fingernail. Abrasive cleaners, scouring pads, and even rough sponges will scratch the surface. While minor scratches can be sanded out, repeated abrasive cleaning creates a worn, uneven appearance. Use only soft cloths and liquid dish soap for daily cleaning.
Professional tip: The green side of a standard kitchen sponge is too abrasive for soapstone. Use only the soft side or, better yet, a microfiber cloth.
2. Don't skip mineral oil applications
Soapstone naturally oxidizes over time, darkening from light gray to deep charcoal. Mineral oil accelerates this process for a uniform appearance. Without oil, your soapstone will develop an uneven patina—darker where it gets more use and lighter in unused areas. Apply food-grade mineral oil monthly for the first year, then quarterly.
Professional tip: If you prefer the light gray color, you can skip oiling entirely—but the darkening will happen naturally and unevenly. Oiling gives you control over the process.
3. Don't panic about scratches
Scratches on soapstone are normal and expected—they're part of the stone's lived-in character. Light scratches often disappear with your next mineral oil application. Deeper scratches can be sanded out with 120-grit sandpaper followed by 220-grit, then an oil application. This is one of soapstone's unique advantages—self-repairing beauty.
Professional tip: Sand in the direction of any existing grain pattern, not against it. Apply mineral oil immediately after sanding to blend the repaired area.
4. Don't use stone sealers on soapstone
Unlike marble and granite, soapstone is non-porous and doesn't need sealing. Applying a stone sealer to soapstone creates a sticky film that attracts dirt, prevents mineral oil from absorbing, and can turn cloudy over time. If a sealer has been applied, it needs to be stripped before returning to proper oil maintenance.
Professional tip: If a contractor or installer sealed your soapstone, you'll notice the oil isn't absorbing evenly. Professional stripping restores the stone to its natural state.
5. Don't place extremely hot items directly on soapstone
While soapstone is more heat-resistant than most stones (it was historically used for wood stoves), extreme thermal shock can still cause cracking in thin sections. Use trivets for pots directly from the stove or oven. The stone can handle warm items, but a 500°F cast iron pan is a risk.
Professional tip: Soapstone's heat retention makes it excellent for serving—it stays warm for a long time. But let hot cookware cool slightly before placing it down.
6. Do embrace the patina
Soapstone develops a beautiful natural patina with age—this is a feature, not a flaw. The stone darkens, scratches blend, and the surface develops a rich, lived-in character. Fighting this process with aggressive cleaning defeats the purpose of choosing soapstone. Embrace the evolution and enjoy a countertop that tells the story of your kitchen.
Professional tip: Visit soapstone installations that are 5–10 years old before choosing your finish approach. Most homeowners fall in love with the aged look.
How often should I oil soapstone countertops?
Monthly for the first year to build up the patina evenly, then quarterly after that. Some homeowners oil weekly during the first month. Use food-grade mineral oil—not olive oil or cooking oils, which can go rancid.
Can soapstone countertops stain?
Technically no—soapstone is non-porous and doesn't absorb liquids. However, oils can temporarily darken the surface. This usually evens out with your next mineral oil application. Soapstone is one of the most stain-resistant natural stones available.
Is soapstone good for kitchens?
Excellent. Soapstone is heat-resistant, non-porous (no sealing needed), acid-proof (no etching from lemon or vinegar), and develops a beautiful patina. The only trade-off is that it's softer and will scratch—but scratches can be sanded out.
How much does soapstone restoration cost?
Professional soapstone restoration in Chicago (sanding, re-oiling, chip repair) typically ranges from $300–$700 depending on the countertop size. Contact Granite Heroes for a free assessment.
