Ritual floor-washing is yet another custom that can rid a house of evil influences, prevent evil from entering the house, and bring in good luck, success, or happiness. To attract good fortune, the floor is washed with an inward motion, from the walls to the center; to eliminate evil, it is washed with an outward motion, from the center to the walls. The wash water usually contains saltpeter, herbal or floral essences, and table salt; agua florida is also used. The wash water should be thrown away into the front yard toward the east, preferably into the sunrise.
