Maintenance and care Cleaning the wiper blades If the wiper blades do not wipe properly, clean the wiper blade rubber element with undiluted windshield wiper solution or a mild detergent. To avoid damaging the blades, do not use fuel, kerosene, paint thinner or other solvents. If the wiper still does not wipe properly, this could be caused by substances on the windshield such as tree sap and some hot wax treatments used by commercial car washes. Clean the outside of the windshield with a non abrasive cleanser such as the non abrasive Bon Amir powder. Rinse thoroughly with clean water. Do not use abrasive cleansers on glass as they may cause scratches. The windshield is clean if beads do not form when you rinse it with water. The windshield and wiper blades should be cleaned on a regular basis, and blades or rubber elements replaced when worn. 246
