If your windshield wipers are streaking, it’s crucial to address the issue promptly for clear visibility and safe driving. Streaking can result from worn-out blades, dirt accumulation, or improper installation. Here’s a comprehensive guide to help you tackle this common problem and ensure your wipers function effectively.

Why Are My Windshield Wipers Streaking?

Common Causes of Streaking

1. Worn-Out Blades: Over time, the rubber on wiper blades can degrade, leading to ineffective wiping and streaks.
2. Dirt and Debris: Accumulated dirt or debris on the blades or windshield can cause streaking.
3. Improper Installation: Incorrectly installed wipers may not make proper contact with the windshield.
4. Weather Conditions: Extreme temperatures can harden or warp the rubber, affecting performance.

How to Fix Streaking Windshield Wipers

1. Inspect and Clean the Blades

Regular cleaning can often resolve streaking issues. Follow these steps:

• Lift the wiper blades from the windshield.
• Use a damp cloth with mild detergent to wipe the blades.
• Rinse with clean water and dry thoroughly.
• Check for cracks or tears in the rubber.

2. Replace Worn-Out Wiper Blades

If cleaning doesn’t work, it might be time to replace the blades. Here’s how:

• Measure the length of your current wiper blades.
• Purchase the correct size from an auto parts store.
• Follow the instructions for installation, ensuring the blades are securely attached.

3. Check Wiper Arm Alignment

Ensure the wiper arms are properly aligned:

• Park the wipers in their resting position.
• Ensure they are parallel to each other and the windshield.
• Adjust if necessary, following your vehicle’s manual.

4. Use Proper Windshield Washer Fluid

Using the right fluid can help prevent streaks:

• Avoid water, as it doesn’t clean effectively.
• Use a high-quality windshield washer fluid that helps remove grime and dirt.
