ABSTRACT:
A new windshield wiper blade assembly with sponge and tension mechanism for removing stubborn insect deposits and other debris from the exterior of a front windshield of a vehicle. The inventive device includes a wiper blade support assembly having a plurality of wiper fluid spray holes and is attached to the oscillating wiper arm of a vehicle. A first wiper blade and a second wiper blade are spaced apart from one another and downwardly depend from the wiper blade support assembly. A scrubbing sponge having a scrubbing surface and a plurality of wiper fluid channels is interposed between the first wiper blade and the second wiper blade. A plurality of wiper fluid hoses in fluid communication with the wiper fluid channels and the wiper fluid spray holes allows wiper fluid to be dispensed to the scrubbing sponge and the windshield. A sponge tension mechanism is mounted to the wiper blade support assembly and applies pressure to the scrubbing sponge to firmly position the scrubbing sponge against the windshield.
