Soapstone is very dense and nonporous, so unlike granite, very little care is needed. Your soapstone countertop doesn’t have to be sealed and resealed over the years in order to prevent stains from seeping into the surface, making it more low-maintenance than granite.
Lab tests show that soapstone is resistant to both acids and alkalis, including stains from tomatoes, wine, coffee, juice, makeup, and other common household products. Soapstone is also impervious to heat, and won’t melt, crack, or incur other damage.
To keep a soapstone countertop clean, any common household cleaner is safe to use, even one with chemicals and acids. The easiest way to care for your stone, however, is simply to wipe it down with regular soap and water.
Mineral oil is not required for protecting the nonporous surface of soapstone. However, some homeowners like to rub a coat of mineral oil across the surface for a lustrous finish that darkens the countertop by a few shades as it dries. Regularly applying mineral oil for the first six months to a year after installation will evenly and permanently darken the stone. Without mineral oil, the countertop will slowly darken in the areas that receive the most everyday use.
