How to Clean Soapstone Countertops:
Soapstone is a natural rock that contains the mineral talc which gives it a soft, smooth feel. The finished surface of soapstone feels like a dry bar of soap (and that’s where it gets its name!). This stone is quarried in two basic types: high talc (artistic) and low talc (architectural). For your kitchen countertop always use low talc, architectural grade soapstone.
Soapstone is an easy-to-care-for stone countertop as it is naturally antibacterial, nonporous, heat resistant and repels most stains. A downside to this stone is that there is a higher risk of scratches and chips if hit with a heavy object as it is not as hard as some other stones.
