A host called me in distress. There is a mutual understaning/agreement in her household. She cooks. He cleans. The other night, her husband was loyally washing up after dinner. She happened to walk out of the room. When she walked back, there he was, standing at the sink, soapy sponge in hand, working away at one of her stones. She screamed at him to stop, and ran (she said it was like the movies, where it was all slow motion) over to the disaster...... This is where I hope you can help. What can she do now? (other than order a new stone) I know baking soda and water paste work on bad stains. But what do you do about a soap washed stone? Thanks all.
