Maintenance, Cleaning & Use
Recommendations for Wiper Maintenance, Cleaning, and Use:
1. Scheduled Maintenance
^ Check rubber inserts every 4 - 6 months or 7,500 miles for wear cracking and contamination.
^ Clean glass and rubber inserts if blades are not clearing glass adequately. If this does not correct the problem replace the rubber inserts.
2. Cleaning Procedure
^ Rubber inserts: Bugs dirt sap and road grime on rubber inserts will cause streaking. Clean road and environmental debris from the rubber
inserts by using a cloth or paper towel soaked with windshield washer fluid or a mixture of mild detergent and water.
^ DO NOT USE fuel kerosene or petroleum based products to clean rubber inserts.
^ Windshield: Bugs sap road grime and car wax treatments decrease rubber insert performance.
^ Rinse the glass with water and apply non-abrasive cleaner such as Bon-Ami or equivalent with a sponge.
Make sure to use plenty of water with all powder based cleaners to avoid scratching the glass surface.
3. Contributors to Poor Performance/Decreased Rubber Blade Life (requiring rubber replacement)
^ Dust or dirt on the glass surface causes the rubber edge to wear quickly.
^ Sand and salt used for road conditioning during Winter months causes the edge to wear quickly so geographical locations with significant
snowfall require more frequent wiper replacement.
^ Heat and length of time in service can cause the rubber to become hard and brittle causing the rubber to not turn over resulting in streaking
and/or unwiped areas on the glass.
^ The use of an ice scraper near the blades can easily damage the rubber insert.
^ Pulling blades oft a frozen windshield can cause the rubber insert to tear.
^ Using wipers instead of an ice scraper to remove frost and ice from the glass can dull nick or tear the rubber.
^ Slamming the wiper on the glass to remove ice & snow can cause the blade to bend and the rubber to come out of the blade increasing the
potential to scratch the glass.
^ When ice forms in wiper blade pin joints it may cause streaking and unwiped areas. To remove ice from pin joints compress the blade and
