4. Removing the Old Wiper Blade Rubber

a. Lift the Wiper Arms

Locate the base of the windshield wiper arms and lift them off the windshield. Do not apply excessive force as this could damage the arms or the wiper assembly.

On most wiper blades, the old rubber can be slid out of the metal frame. Use your fingertips to gently pull the rubber towards you, starting from one end.

c. Cut Off the Excess

Using scissors, cut off any excess old rubber that may still be attached to the metal frame.

5. Cleaning the Metal Frame

Before installing the new rubber, it is important to clean the metal frame to remove any dirt or debris that may interfere with proper adhesion. Use rubbing alcohol and a clean cloth to wipe down the frame thoroughly.

Once the rubber has been inserted along the entire length of the frame, use scissors to trim any excess.

7. Reinstalling the Wiper Arms

Once the new rubber is installed, carefully lower the wiper arms back onto the windshield. Ensure that the arms are securely attached.

8. Testing the Wiper Blades

Turn on the windshield wipers and test their functionality. The blades should move smoothly and wipe the windshield clean. If any streaks or gaps are observed, repeat the installation process to ensure proper alignment.
