How Long Do Wiper Blades Last? A Comprehensive Guide

How Long Wiper Blades Last

Quick lube places often recommend wiper blade replacement at almost every oil change, but that’s their way of upselling you unnecessary replacements. But how long do wiper blades last? The answer to this question varies depending on several factors, including the type of wiper blades, driving conditions, and how well they are maintained. In this article, we’ll explore the lifespan of wiper blades, signs that they need replacement, and tips on how to extend their life.

How Long Do Wiper Blades Last: The Average And The Extreme

You should change your wiper blades at least once a year. Even if your wiper blades don’t make noise when you operate them, they’re most likely starting to streak after a year. However, if you drive in any of the conditions listed below, you may have to change them as often as every six months.

• Dusty driving conditions—  If you live in a desert area, drive on dirt or gravel roads, live in an area where road salt and sand are used in winter, your wiper blades can wear out faster than the average. All that gritty material acts like sandpaper to wear down the sharp edge of the rubber squeegee.
• Long exposure to UV rays— Sunlight deteriorates both the blade rubber and the plastic frame. If you park your vehicle outside in the sun, the rubber blade will degrade faster.
• Frequent use— Obviously, the more you use them, the more they wear out. They’re rubber squeegees after all and the more they wipe, the more it wears down the sharp edge of the rubber.
• A Cracked or Chipped windshield— A crack or chip in your windshield can cut the blade rubber and cause streaks in as little as a few months.

What are the symptoms of worn wiper blades?

• Streaks: Worn wiper blades smear across the windshield or cause streaks. That’s the first sign that they’re worn.
• Noise: When your wipers chatter and screech across the glass, that’s also a sign that they’re worn.
• Cracks: Sunlight causes the rubber to crack and streak
• Tears: The rubber squeegee tears away from the base portion of the wiper
• Frame damage: The metal or plastic tension arms break or come apart

The best time to replace them

In Spring before the rainy season starts. If you’ve used your wipers over the winter and notice streaking, replace them before spring rains begin.

In the Fall before winter. If you live in a snowy area, you’ll want new blades to increase visibility on dark winter nights.
