One of the main reasons you should replace your windshield wipers is to protect your safety and avoid collisions when it's raining outside. New windshield wipers come with better materials and allow the rubber material to have better contact with the glass. When you replace your current wipers, the new parts won't cause any streaks to be left on the glass as they're in motion. They also won't cause damage to the windshield, which can protect your pocketbook. In addition, they have a longer lifespan and can allow you to have more confidence with seeing the road to ensure you stay safe when it's wet outside.
