The condition of the windshield wiper affects the windshield in car in more ways than one. The windshield wiper is made of two components broadly – a metal
structure on the inside and a rubber coating on the outside. When the rubber coating wears out, your windshield is exposed to the metal structure. This means, each time you run the wipers, the metal body scrapes against the windshield, which could leave serious scratches on the glass. Wiper blades degrade over time due to wear and tear, debris, moisture, and sunlight and it is advised that you replace them at least once a year to protect your windshield.
