The harshest chemicals you will usually need
is soap and water.
When some stones get scratched they need professional resurfacing to remove them. This can be a tedious process for everyone involved. The softness of soapstone allows for most scratches to be removed simply with just some sandpaper and mineral oil!
Plus, soapstone does not need to be sealed before use!
Soapstone is a dense, non-pourous and non-absorbent material. These properties naturally reduce bacteria growth and prevent staining on it's surface.
Some water and any gentle cleanser is all that is needed to clean the stone!
