How to Remove Liquid Soap Stains from Bluestone

Q. I have a bathroom counter that is bluestone. Before it could be sealed a bottle of liquid hand soap was put on the surface forming a ring. Also several drops of soap were dropped on the surface causing spots. What is the best method for removing the stain. If it needs poulticing what combination of absorbent material and solvent do you recommend?

A. Create a poultice paste by mixing liquid degreaser, which can be purchased at most home centers, and flour. Apply the poultice to the spots. For additional help see our Stain Management App. It may take several poultice applications to remove the stains.
