    Common Wiper Blade Problems

    Being made of rubber-based compounds and exposed to extreme weather conditions such as rains, dust and a host of pollutants, wiper blades become hard and brittle. When the wiper blades reach this stage they are unable to clear the windshield properly resulting in streaks/ dirty / permanent damage to the windshield.


    Wiper blades deteriorate due to many factors some of which including

    • Sun: Ultraviolet light and ozone deterioration
    • Oil: Car waxes and exhaust hold rubber-deteriorating oil
    • Airborne debris: Sand, mud and dust carried in the wind
    • Moisture: Acid rain and salt water (in moist air both near the shore and inland)
  • Preventive Maintenance

    Keeping your windshield clean and your wipers in top shape gives you the ability to see clearly what is going on around you on the road. Clear visibility on the road can be a life saver. That’s why taking the time to think about preventive maintenance on your windshield wiper blades is critical to safe driving. Remember to check these points (points will be on auto parts website) while inspecting your wiper blades

    • Broken frame – for detachment of frame arms at joints or connection points
    • Metal corrosion - especially at joints and claws
    • Visible cracks, tear and missing pieces in the rubber's edge
    • Flex rubber back and forth to see if it is still flexible. Aged rubber will have difficulty conforming to the shape of your windshield and create streaks.
    • Check rubber wiping edge for rounded edges which can prevent the wiper blade from making strong contact with the windshield and reduces wipe quality.
    • Tug to ensure wiper blade has been securely installed on the wiper arm.
    • Check that rubber is secure in the wiper frame.
  • Maintenance Tip

    Depending upon environmental conditions, wiper blades can have dramatic differences in their lifespan and operation. The following tips may help you to maximise wiper performance and to avoid damage to the blades and avoid untimely replacements.
