WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when
they seem less effective. Substances such as tree sap
and some hot wax treatments used by commercial
car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both
the windshield and wiper blades using undiluted
windshield wiper solution or a mild detergent. Rinse
thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or
other solvents.
