To Take Grease from Wood and Stone.
Put one gill of washing soda and one quart of boiling water in a stewpan and place on the fire. When the soda is dissolved, pour the boiling liquid on the grease spot. Rub with an old broom. An hour or two later rub with a mop. Rinse out the mop; then wash with clean hot water. Be careful not to get the soda water on your hands, clothing, or boots.
