How to Prevent Windshield Cracks from Expanding?
2 Answers
Here are some tips to prevent windshield cracks from expanding: 1. Regularly check wiper blades: Wiper blades are one of the main causes of windshield damage. Over time, wiper blades can wear out, and if the end of the wiper arm rubs directly against the windshield, it not only fails to clean rainwater effectively but can also scratch the glass. Additionally, dust adhering to the wiper blades can cause small scratches and fine lines on the windshield. At high speeds, even these tiny scratches can lead to windshield breakage. Although the probability is low, some sudden windshield shattering incidents on highways without an apparent cause are actually due to these accumulated minor scratches. 2. Clean the windshield: Always use designated windshield washer fluid, which contains components that dissolve grease and improve the wetting interface of the glass, helping to maintain the glass. When there are obstacles like snow, ice, mud clumps, or dried bird droppings on the glass, avoid using the wiper blades, as this can damage them.
Last time I drove, a small crack appeared on my windshield, and I took immediate action to prevent it from expanding. The key is to avoid sudden temperature changes—don’t wash the car under scorching sun or blast the AC suddenly. I first used something to temporarily secure the edges of the crack, like firmly applying transparent tape, which helps reduce stress. While driving, I also try to avoid bumpy roads and keep my speed moderate to prevent vibrations from spreading the crack. Another trick is to visit a professional shop early for resin filling repair—it’s affordable and efficient. Delaying could turn a small crack into a big problem. I also make sure to clean the glass regularly to prevent dust buildup from worsening the damage. Remember, prevention is much more cost-effective than replacing the entire windshield.
