Windshield wiper blades/elements are frequently replaced unnecessarily. Because of the environmental conditions vehicles can be operated in, a film can build up on both the windshield and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in some instances, a chattering condition as the wipers blades travel across the windshield.
Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that is required.
