  • Patent number: 5101530
    Abstract: An improved, light-weight squeegee suitable for use in and around the home for cleaning and drying shower and tub enclosures, windows, and spa decks, or autos and boat decks. The squeegee is constructed without metal parts that could scratch glass, ceramic and painted surfaces or that could corrode and stain such surfaces. A cylindrical handle holds dual S-shaped blades, which extend along the handle and beyond one end of the handle to facilitate cleaning in tight spaces. The unitary blades are coextruded from thermoplastics having different hardnesses, the roots of the blades held in the slotted handle being stiff, while the extended portions of the blades used for wiping surfaces are relatively flexible. The compact size and the integral handle parallel with the blades allows the user to maneuver the squeegee efficiently in the narrow confines of glass enclosures.
