How often do you change out your windshield wipers? According to a Safelite AutoGlass survey, 65% of us change our wipers once a year, and 23% do so once every two to three years when they start to go on the blink. That’s probably too long. After all, your windshield wipers provide visibility in rain and snow. Knowing when to replace your wipers can help you maintain solid visibility and stay safe on the road.
1. Streaking and Smearing
One of the most obvious signs that your wipers need replacement is when they leave streaks or smears across your windshield. Wiper blades should clear water completely with each pass. If you notice lines of water remaining after the wiper moves across the glass, the rubber edge has likely worn down or become uneven, preventing it from making proper contact with your windshield.
2. Skipping or Chattering
When your wipers make a stuttering motion across the windshield or skip sections altogether, this indicates the rubber has lost its flexibility. First of all, this chattering sound is annoying. And second, it’s a warning sign. With temperature fluctuations, they can cause rubber to harden over time, especially in regions with extreme weather. Once the blade loses its pliability, it can’t conform to the curvature of your windshield, and it simply doesn’t work as well as it should.
3. Squeaking Noises
While some squeaking might occur when wipers move across a nearly dry windshield, persistent squeaking during regular rain conditions suggests the blades are worn. This noise happens when friction increases between the rubber and glass due to deterioration of the wiper edge or a buildup of debris.
4. Visible Damage
It’s always a good idea to occasionally inspect your wiper blades. Look for signs of cracking, splitting, or chunks missing from the rubber edge. You can also check for corrosion or damage to the metal frame. Any visible wear indicates it’s time for replacement, even if the wipers seem to be functioning pretty well during light rain.
5. Bent Frame or Detachment
If your wiper frame becomes bent or partially detaches from the arm, immediate replacement is necessary. This damage often occurs from ice buildup, improper clearing of snow, or even car wash equipment. A compromised frame cannot maintain proper pressure against the windshield, which leads to poor clearing performance.
6. Reduced Visibility in Light Rain
If you find yourself straining to see clearly during light drizzle, your wipers might be failing. As with chips in a windshield which can compromise visibility, you want to make sure you have quality wipers that can clear moisture without leaving a film or water droplets that distort your vision. Don’t wait for a downpour to confirm what you already suspect in milder conditions.
7. Seasonal Changes
As a general rule, replace your wipers seasonally—typically every six months. The change of seasons from winter to summer and back again is an excellent reminder to check or replace your wipers. Winter’s harsh conditions particularly tax wiper blades, as ice, salt, and extreme temperatures accelerate deterioration.
Closing Thoughts
Your windshield wipers are your first line of defense against reduced visibility. Replacing them costs relatively little compared to the safety benefits they provide.
