Rear Wiper System
WARNING: This page is about a different car, the 2014 Fiat 500e. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Protect the rubber squeegee of the wiper blade from any petroleum-based cleaners, solvents or contaminants. These products can rapidly deteriorate the rubber squeegee.
The squeegee of a wiper blade exposed to the elements for a long time tends to lose its wiping effectiveness. Periodic cleaning of the squeegee is suggested to remove any deposits of salt or road film. The wiper blade, arm and liftgate glass should only be cleaned using a sponge or soft cloth and windshield washer fluid, a mild detergent or a non-abrasive cleaner. If the wiper blade continues to leave streaks, smears, hazing or beading on the glass after thorough cleaning of the squeegees and the glass, the entire wiper blade assembly must be replaced.
