Wiper blades harden and/or break down over time. This process happens faster if you drive in particularly hot or cold conditions. So, it’s important to check your wiper blades regularly and have a complete wiper blade replacement when they are cracked or hard.
Rubber is a natural compound and breaks down for a variety of reasons, including:
Heat. The summer sun can heat up your vehicle’s windshield and literally bake the wiper blades. This extreme heat can cause wiper blades to harden and crack.
Environment. Vehicles in high-traffic areas tend to be exposed to a higher concentration of ozone, which can oxidize the rubber blades and create cracks.
Cold. Frigid weather causes rubber blades to harden and lose flexibility. When this happens, water can leak underneath the blades and cause smearing.
While most wiper manufacturers recommend changing your wiper blades every 6-12 months, we recommend that you check your wiper blades often and replace them when you notice that they’re hard or cracked.
