Most experts say that wiper blades need to be changed every six to 12 months. This depends on weather conditions and the quality of blades you purchase. Ordinary rubber blades have the shortest lifespan. Halogen-hardened rubber blades last a bit longer. But silicon blades have the longest lifetimes of all, perhaps exceeding a year even under intense use. Of course they also cost more than ordinary rubber blades.

You’ll know when your wiper blades need to be replaced because you’ll see streaking as they wipe the moisture from the windshield or even large gaps where no water is being removed. They may start making squeaking or chattering sounds (though this can also happen if you run the wipers when the windshield is mostly dry). If left unchanged for too long, the material of the blade can shred and break loose from the arm. This can actually cause damage to your windshield, as the metal or hard plastic of the arm scrapes across the glass. This is not preferred.

Fortunately, you won’t necessarily have to replace the entire blade assembly. Most blade arms will accept rubber refills, giving you the option of replacing only the part that’s damaged. However, blade arms can become bent over time, so make sure that the refill is all that you need to replace in order to fix the problem.
