  • Patent number: 8567470
    Abstract: A tool and method for removing a film from a surface is provided, wherein the tool can include a frame, a handle operably coupled to the frame, a number of wheels operably coupled to the frame, a cylinder rotatably coupled to the frame, an arm rotatably coupled to the frame, and a number of separating devices operably coupled to the arm. In some embodiments, the wheels can rotate about one or more axes parallel to the surface. The cylinder, which collects the removed film, rotates about an axis that can also be parallel to the surface. The arm can rotate about an axis that can also be parallel to the surface.

  • Patent number: 7071153
    Abstract: The present invention is directed to a method of enhancing the appearance of a soiled porous surface. The inventive method includes applying a concentrated, alkaline, cleaning composition to the soiled porous surface. This concentrated, alkaline, cleaning composition is then allowed to remain on the surface for a period of time before it is rinsed with water. After drying, a maintainer composition is then applied to the surface. The maintainer composition includes a pore-filling component. The cleaning composition includes an alkaline source and, optionally, a solvent.
