A windshield wiper comprises a wiper blade including a squeegee portion for contacting a surface and a body supporting the squeegee portion. A primary spline is engaged with the body and has a first closed end and a second open end. A support structure is provided to attach the wiper to a wiper arm on a vehicle. At least one spoiler is slidingly disposed on the primary spline above the secondary spline. A secondary spline is slidingly disposed between the body and the support structure, whereby the secondary spline is retained in place by caps disposed at the first and second ends of the primary spline. The secondary spline is removably disposed between said wiper blade and said support structure and retained in place by end caps.
