[0001] This is a continuation-in-part of application Ser. No. 10/946,662 filed Sep. 22, 2004 and entitled WIPER BLADE FOR GLASS SURFACES AND ASSOCIATED METHOD OF MAKING, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] This invention relates generally to vehicle parts and accessories and relates, more particularly, to wiper blades used for cleaning glass surfaces of vehicles and methods of making such blades. [0003] Conventional wiper blades used for wiping glass surfaces of vehicles have heretofore been constructed of a smooth, flexible material, such as rubber, which is intended to clean the glass surface as the wiper blade passes repeatedly back and forth across the glass surface. However, some substances (such as bugs or bird dropping) which occasionally come into contact with the glass surfaces of a vehicle are difficult for common wiper blades to remove. It would therefore be desirable to provide an improved wiper blade which is capable of removing hard-to-remove substances from the glass surface of a vehicle--whether the glass is dry or wetted. [0004] Accordingly, it is an object of the present invention to provide a new and improved wiper blade which is capable of removing hard-to-remove material from the glass surfaces of a vehicle more easily than does conventional wiper blades and a method of making the wiper blade. Exemplary applications for such a wiper blade include the windshield and other glass surfaces (such as headlamps) of commercial and private vehicles including, but not limited to, automobiles, trucks, aircraft, boats, construction and farm machinery, and motorcycles. [0005] Another object of the present invention is to provide such a wiper blade which is capable of cleaning glass surfaces of a vehicle with fewer back and forth passes than would otherwise be required with a wiper blade of conventional construction and which is capable of cleaning glass surfaces whether the glass surfaces are in a dry or wetted condition. [0006] Still another object of the present invention is to provide such a wiper blade which embodies a material for brushing hard-to-remove material from the glass surface of a vehicle. [0007] Yet another object of the present invention is to provide such a wiper blade which be used to clean the glass surfaces, such as windshield or lamp surfaces, on any of a number of vehicles. [0008] A further object of the present invention is to provide such a wiper blade which, when used for cleaning a windshield, helps to maintain the glass surface is a relatively clean condition and thereby enhance visibility through the windshield glass. [0009] A further object of the present invention is to provide such a wiper blade which is uncomplicated in structure, yet effective in operation. SUMMARY OF THE INVENTION [0010] This invention resides in a wiper blade having an elongated wiper-providing body including a spine portion and a wiping element extending from the spine portion for engaging and wiping glass as the wiper blade is moved thereacross and wherein the wiper-providing body includes a longitudinal axis. [0011] The improvement includes an elongated cleaning element for cleaning the glass with the wiping element as the wiper blade is moved across the glass. The cleaning element is joined to the wiper-providing body to permit longitudinal movement of the cleaning element relative thereto and to permit movement of the cleaning element relative to the wiper-providing body toward and away from the spine portion as the wiper blade is moved across the glass. In addition, a magnetic device is joined to the wiper-providing portion for biasing the cleaning element away from the spine portion of the wiper-providing portion so that upon placing the wiping element and the cleaning element into engagement with the surface of the glass to be cleaned, the cleaning element is biased toward the glass surface by the forces of the magnetic device exerted upon the cleaning element and is maintained in a spaced relationship with the spine portion so that as the wiper blade is moved across the glass surface, the cleaning element is permitted to move relative to the wiper-providing element and the spine portion as aforesaid. BRIEF DESCRIPTION OF THE DRAWINGS [0012] FIG. 1 is a perspective view of a vehicle and a wiper blade assembly shown utilized for cleaning the windshield glass of the vehicle wherein the wiper blade assembly includes a wiper blade which embodies features of the present invention. [0013] FIG. 2 is a side elevational view of a major portion of the wiper blade assembly of FIG. 1. [0014] FIG. 3 is a view of a transverse cross section of the wiper blade of FIG. 1 taken generally along line 3-3 of FIG. 4. [0015] FIG. 4 is a view similar to that of FIG. 3 illustrating another embodiment of a wiper blade. [0016] FIG. 5 is a view similar to that of FIG. 3 illustrating still another embodiment of a wiper blade, shown exploded. [0017] FIG. 6 is a view similar to that of FIG. 3 illustrating yet another embodiment of a wiper blade. [0018] FIG. 7 is a view similar to that of FIG. 3, but showing the blade of FIG. 3 being used to clean the surface of glass. [0019] FIG. 8 is a fragmentary perspective view of yet another embodiment of a wiper blade within which features of the present invention are incorporated. [0020] FIG. 9 is a transverse cross-sectional view of the FIG. 8 embodiment, shown exploded. [0021] FIG. 10 is a fragmentary perspective view of the cleaning element of the FIG. 8 embodiment.
