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 ªpermanent set,º so
the rubber does not turn over, resulting in streaking and/or unwiped areas on
the glass.
Rubber is easily cut or torn while using ice scrapers on the glass.
Rubber can be torn when pulling blades off a frozen windshield.
Using wipers instead of an ice scraper to remove frost and ice from the windshield
during a car warm up can dull, nick, or tear the rubber.
Banging wiper on the glass to remove ice & snow can cause the blade to bend
and rubber to come out of the blade providing the potential to scratch the glass.
Ice forms in wiper blade pin joints, which causes streaking and unwiped areas.
To remove ice from pin joints, compress the blade and rubber with your hand to
loosen the frozen joints. To prevent this condition, use winter blades with a
rubber cover.Maintenance,
