Maintenance, Cleaning & Use
Recommendations for Windshield Wiper Maintenance, Cleaning, and Use:
1.
Scheduled Maintenance
^
Check wiper rubber blades every 4 - 6 months or 7,500 miles for wear, cracking, and contamination.
^
Clean glass and rubber wiper blades if blades are not clearing glass adequately. If this does not correct the problem, then replace the rubber
elements.
2.
Cleaning Procedure
^
Wiper Rubber: Bugs, dirt, sap, and road grime on blades will cause streaking. Clean wiper rubber of road and environmental debris using cloth
or paper towel soaked with windshield washer fluid or mild detergent.
^
DO NOT USE fuel, kerosene, or petroleum based products to clean rubber wiper blades.
^
Windshield: Bugs, sap, road grime, and car wash wax treatments decrease wiper performance.
^
Rinse windshield with water and apply non-abrasive cleaner, such as Bon-Ami (www.faultless.com), with a sponge.
NOTE:
Make sure to use plenty of water with all powder based cleaners so the glass is not scratched.
3.
Contributors to Poor Performance/Decreased Rubber Blade Life (require rubber replacement)
^
Dusty areas cause the rubber edge to wear quickly.
^
Sand and salt used for road conditioning during winter causes the edge to wear quickly, so areas with significant snowfall require more
frequent wiper replacement.
^
Heat and time cause the rubber to become excessively "permanent set," so the rubber does not turn over, resulting in streaking and/or unwiped
