Hueston uses a polishing tool and marble-polishing powder to smooth the surface, which was etched by the acidic coffee. He attaches a polyester polishing pad to the Velcro drive plate, then spreads the gritty polishing powder over the surface and splashes on a tablespoon of water. For marble and limestone, he sprinkles an abrasive powder made from aluminum oxide and oxalic acid; for granite, he uses a tin oxide powder. He works the powder over the rough stone, moving the polisher in small circles. When he feels the resistance ease, he stops and wipes the surface with a dry cloth, then visually inspects the area and glides a hand over it to check for smoothness.
