In the cleaning bath, streams mostly being directed away from a predetermined plane approximately perpendicular to the overflowing surface are formed. The plate-shaped article is then brought into the cleaning liquid having the stream maintaining a state where the plate-shaped article intersects the predetermined plane and the surfaces of the plate-shaped article are in approximately parallel to the streams mostly being directed away from the predetermined plane on the surface of the cleaning liquid.
