Abstract: The object of the present invention is to save labor, reduce cost, and to make detergents and wax unnecessary. Water quality improving materials used in a washing device are provided, wherein; raw ceramic powder material containing tourmaline is adhered on the surfaces of ceramic carriers, and then fired to form tourmaline containing films, whereby washing powder is improved by activating water and the contained boric silica S1, S2 . . . adheres onto the surface W of an automobile, etc. As a form thereof, the boric silica S1, S2 . . . is adhered by an electrode position action due to the electrical charges generated by tourmaline and the water is activated by these electrical charges.
