431. To remove Stains from Floors.--For removing spots of grease from boards, take fuller's earth and pearlash, of each a quarter of a pound, and boil in a quart of soft water. While hot lay the mixture on the greased parts, allowing it to remain on them from ten to twelve hours; after which it may be scoured off with sand and water. A floor much spotted with grease should be completely washed over with this mixture the day before it is scoured. Fuller's earth and ox-gall, boiled together, form a very powerful cleansing mixture for floors or carpets. Stains of ink are removed by the application of strong vinegar, or salts of lemon.
