How do worn-out wiper blades contribute to streaks on a Prius windshield?

Over time, wiper blades crack, harden, o r wear unevenly, causing them to leave streaks instead of wiping smoothly. Prius owners should check for visible rubber damage and replace wipers every 6–12 months.

Worn-out wiper blades lose their flexibility and shape over time. As a result:

Cracking o r hardening: The rubber material of the wiper blade can crack o r harden, causing uneven contact with the windshield.
Uneven wiping: The blade may not make full contact with the glass, leaving streaks in areas where it doesn’t properly clean.
Rubber damage: Prius owners should inspect the rubber for visible damage and replace the wiper blades regularly, ideally every 6 to 12 months to ensure effective cleaning.
