A sponge has rectangular faces and a trapezoidal cross-section to enable the sponge to reach into corners and the like. The sponge is detachably secured below a plate which is itself attached to the lower end of an elongated handle. An elongated wringer plate having a center grill can be swung below the sponge and lifted up against the sponge by a lever attached to the handle, to wring the sponge out against the plate.
