Download Maintenance, Cleaning and 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, road grime, sap 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.
