What Causes the Uneven Texture When Touching the Car Windshield?
2 Answers
An uneven texture when touching the car windshield might indicate a substandard product. Types of automotive glass: Laminated glass, tempered glass, and zone-tempered glass, which can withstand strong impacts. Automotive glass by location: Front windshield, side window glass, rear windshield, and sunroof glass. Automotive glass regulations: National regulations mandate that the front windshield must be laminated glass. Some low-cost agricultural vehicles may still use tempered or zone-tempered glass for the front windshield. Side windows are made of tempered glass, while the rear windshield typically features tempered glass with electric heating wires.
I'm a seasoned car enthusiast with years of experience, and I've encountered the issue of uneven windshield texture several times. Most often, it's due to the aging of the glass surface, where prolonged exposure to sun and rain makes it rough like sandpaper. Additionally, dried insect remains or bird droppings from the road can leave small bumps, creating a pitted feel. Another common cause is using a hard brush for quick cleaning during car washes, which scratches the surface and, over time, leads to an uneven texture. This roughness not only feels unpleasant but also causes glare and blurred vision while driving, especially dangerous at high speeds. My advice is to first try softening the stains with a neutral detergent and warm water, gently wiping them away. If that doesn't work, it's best to visit a car shop for polishing sooner rather than later. Also, covering your car with a protective cover when parked can add an extra layer of defense, extending the glass's lifespan.
