If your windshield wipers are leaving streaks, it is crucial to address the issue to ensure clear visibility and safe driving. Streaks can occur due to various reasons, such as worn-out blades, dirt, or improper installation. Here’s a comprehensive guide on how to fix this common problem.

Why Are My Windshield Wipers Leaving Streaks?

Understanding the root cause of streaky wipers is the first step in resolving the issue. Several factors can contribute to streaks:

• Worn-out Blades: Over time, the rubber on wiper blades can degrade, leading to uneven wiping.
• Dirt and Debris: Dust, dirt, or insect residue on the windshield or blades can cause streaking.
• Improper Installation: Incorrectly installed wipers may not make proper contact with the windshield.
• Damaged Windshield: Scratches or chips on the glass can also lead to streaks.

How Can I Fix Streaky Windshield Wipers?

1. Clean the Windshield and Wipers

Start by cleaning both the windshield and the wiper blades. Use a glass cleaner and a microfiber cloth to remove any dirt or grime from the windshield. For the wiper blades, a damp cloth with a bit of rubbing alcohol can effectively clean and restore their performance.

2. Inspect and Replace Wiper Blades

If cleaning does not resolve the issue, inspect the condition of the wiper blades. Look for signs of wear such as cracks, splits, or a hardened rubber edge. If the blades are worn out, replace them with new ones. Here’s how you can do it:

1. Lift the wiper arm away from the windshield.
2. Press the small tab on the underside of the wiper blade to release it.
3. Slide the old blade off and attach a new one by reversing the process.

3. Check for Proper Installation

Ensure that the wiper blades are correctly installed. They should sit snugly against the windshield without any gaps. If you’re unsure, consult the vehicle’s manual or a professional for guidance.

4. Examine the Windshield

Check for any damage on the windshield that might be causing streaks. Minor scratches can sometimes be polished out, but significant damage may require the attention of a professional.

5. Use a Windshield Treatment

Applying a windshield treatment can help repel water and reduce streaks. These treatments create a hydrophobic layer that allows water to bead and roll off the glass.

How Often Should I Replace My Wiper Blades?

Wiper blades should generally be replaced every 6 to 12 months, depending on usage and environmental conditions. Regular inspection can help you determine if replacement is needed sooner.
