Streaky wiper blades aren't just annoying—they can be downright dangerous, especially in heavy rain or snow. If you've just replaced your wiper blade refills but still see streaks or smears, don't worry—you're not the only one. Let's look at the most likely causes and how to fix them.
1. The Refill Material Is Worn or of Low Quality
Even new wiper blade refills can streak if they're made from cheap rubber. Low-grade materials tend to wear out quickly, especially under sun exposure or extreme weather. For the best performance, look for natural rubber or include a silicone coating to resist aging and stay flexible.
Tip: For longer-lasting refills, pick ones with UV-resistant and weatherproof rubber.
2. Improper Installation
Wiper refills need to be perfectly aligned and securely installed. If they're twisted, loose, or not fully inserted into the blade frame, they won't glide smoothly across the glass—leading to streaks, skipping, or even scratching.
Quick Tip: After installation, gently run your finger along the blade to make sure the rubber sits evenly in the frame.
3. Dirty or Oily Windshield
Sometimes, the issue isn't the wiper—it's the glass. Dirt, road grime, or oily residues can prevent the blade from making full contact with the surface. This creates uneven pressure and visible streaks, even if the blades are brand new.
Quick Fix: Before testing new refills, give your windshield a deep clean with a good glass cleaner.
4. Wiper Arm Pressure Problems
Wiper arms apply pressure to hold the blade against the windshield. If the spring mechanism is weak or the arm is bent, it may not press the blade down evenly. This can cause one side to streak while the other wipes clean.
Tech Tip: If your blade is only streaking in one spot, check the arm tension and alignment.
5. Using the Wrong Type of Refill
Not all refills fit all blade frames. Using a generic refill on a specialty wiper arm may result in poor contact or improper movement. It's important to match the wiper blade refill size and shape to the original blade type.
Installation Tip: Always check the refill compatibility with the blade model, especially for beam or hybrid styles.
