Any cleaner is acceptable for soapstone but keep in mind that the more aggressive the cleaner, the more it will strip off the mineral oil. For daily cleaning we would recommend using a dishwashing liquid (Palmolive, Dove, Joy etc).
Any common household cleaner can be used to clean soapstone counter surfaces. Chemicals and acids do not harm it. However, we do recommend that you use regular soap and water because harsher solvents may remove the mineral oil treatment, therefore generating more maintenance.
Soapstone is impermeable to heat, acid, and other alkalis and harsh chemicals as an inert material. You can use virtually any soapstone cleaner to care for this beautiful, indelicate product. Still, we recommend avoiding harsh cleaners that could exacerbate skin and sinus irritations in your guests.
If you don't have a coating on your natural stone surfaces but are still worried about disinfecting, regular Clorox Wipes can be used to give your counters a wipe down in a pinch, but don't let them sit directly on the stone!
Scratches on soapstone are, however, not particularly difficult to remove though. The fact that it is a non-porous material, prevents it from experiencing the same damages from abrasive substances such as vinegar, Windex, ammonia, and bleach that other countertops typically experience.
Clean stone surfaces with warm water and a mild soap such as a clear Dawn Liquid Soap. Do not use products that contain lemon, vinegar or other acids on marble or limestone. Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently.
Believe it or not, bleach will not harm it either. However, Bleach is not needed, since the soapstone's natural high density will not harbor bacteria of any kind. Simple soapstone and water or vinegar and water. Will work wonderfully well and clean any surface bacteria just as well as bleach or harsh cleaners.
Soapstone surfaces need not be sealed, but we recommend treatment with mineral oil if consistent surface darkening is desired. Without treatment, soapstone will darken in uneven regions around surface areas most frequently used. Leaving the soapstone untreated will develop a patina of age that many people enjoy.
Soapstone is chemically inert, meaning it will not react to any chemicals or other substances on your countertops, i.e. acids just as lemon juice, wine, etc. This also means that you can use a harsher anti-bacterial treatment such as Lysol or bleach and it will have no negative reaction.
Soapstone is both chemical resistant and heat resistant, so you can set hot pots and pans directly on soapstone without risk of cracking or scorching. Soapstone is much softer and more prone to scratching than granite or quartz however, so preparing food directly on your soapstone counters could easily scratch it.
"It is a softer material, so it does scratch easier," Carbia says. Homes with children who drop things, or homeowners who prefer cutting straight on the countertop as opposed to using a cutting board, might damage soapstone.
Soapstone is used because it's heat resistant and needs little maintenance.
The application of mineral oil is the most commonly mentioned method of restoring the look of soapstone counters. Mineral oil works to quicken the natural darkening process of soapstone and leaves off a soapy residue (that's why it's called soapstone!).
Since soapstone is non-porous, it is easy to clean. However, you need to use mild soap and a soft sponge.
Regularly Wet Areas
On the upside, this means that soapstone doesn't stain and it doesn't need to be sealed — chalk that up to a point in the “low maintenance” column! However, the fact that soapstone is non-porous also means that it doesn't absorb liquids that may be spilled or dragged across the surface.
With soapstone, if water droplets leave a dark spot, re-oil. Wax, on the other hand, is known for giving your soapstone an even richer, deeper color. The deep, charcoal gray created by these special waxes is breathtaking. Some homeowners claim the soapstone countertops treated with wax feel smoother to the touch.
To preserve the color of your soapstone, it should be resealed every three or four years. The frequency may depend on the amount of stress the sealant is exposed to; however, scratches on the surface of the sealant usually only require application to the affected area.
After that, you should plan to oil your stone once every month or when your counters start to get too light. If your sink happens to lighten up quicker than the rest of your countertops, we recommend our mineral oil and bee's wax combination. It may take a bit more elbow grease, but it's sure to last longer.
Mineral oil is recommended for coating Soapstone sinks and counter-tops.
Alberene Soapstone wax can be applied as frequently as needed depending on the shade of black that you desire. Zajac suggests applying the wax weekly in the beginning to make the soapstone darken faster than normal.
To care for soapstone, we recommend applying dry-wax, mineral or baby oil to the surface of your soapstone 24 hours after it is installed. We do not automatically apply anything because all the silicone and caulks used during installation need to cure for 24 hours after installation.
Polishing Soapstone with oil
Using a soft cloth, wipe on a light coat of boiled linseed oil. Tung oil or Danish oil can also be used. Do not apply heavy coats or the oil will become gummy and hard to polish. Wipe off the excess oil and allow drying.
Rub the stone with oil. Use firm, circular motions over the stone's entire surface. Apply more oil as needed (a drop at a time) until you have created a shiny finish over the entire surface of the stone.
Soapstone is a rare stone. This makes it relatively more expensive compared to man-made countertop materials. The average cost of soapstone countertops ranges between $70 to $120 per square foot, excluding installation.
