  • Cleaning the wipers
    1. Grease, oil, and other grimy substances are the most common causes of streaking. Rubbing alcohol or isopropyl alcohol is an effective cleaner to remove this grime.
    2. Lift the windscreen wipers from the glass and into position.
    3. Apply some rubbing alcohol onto the microfibre cloth.
    4. Pinch the blade, wipe up and down from one end to the other as often as it takes until you see no more gunk on the cloth.
  • Clean the windshield
    1. Spray the glass cleaner on the windscreen.
    2. Buff with waffle-weave microfibre cloth to achieve a streak-free shine.
  • Lubricate the hinges
    1. Spray WD40 into the hinges.
    2. Swing the blade backwards and forwards to allow the WD40 to penetrate into the nook and crannies of the hinges.

Tip: Make sure that the wiper blade is at a perfect 90° angle to the glass surface. To correct, twist the wiper arm gently to align at the correct angle.

Maintenance is key

Over time, the rubber blades will eventually wear out. Ultraviolet radiation is the main culprit, so to prevent them becoming hard and brittle prematurely, try to keep park in the shade whenever possible. However, regular cleaning and inspection of your wiper blades will help increase their lifespan and give you many more years of good use.
