Soapstone, how do I clean?

[chynablue]

How do I clean soapstone, I have bought 2 pieces from an auction and soaked one in fairy and water and lots of yuk came off, but it looks like it needs a polish! So before I try and clean the other , does anyone have any tips please?

em you polish them after you have sculpted on them.
