What Causes Many Pockmarks on the Windshield?

Ceramic dots are pressed at the edges of the film during cutting, making it difficult to remove bubbles from the inside. Bubbles at the edges of the front and rear windshields are hard to shrink and adhere, resulting in many pockmarks on the windshield. Windshield Precautions: Do not wash the car within three days after replacing the windshield. Remove the tape fixing the windshield position after three days. Try to avoid driving on excessively bumpy roads and refrain from sudden braking or rapid acceleration to prevent the windshield from shifting. Do not insert parking permits or other cards into the gap between the front windshield and the dashboard. Windshield Maintenance: Use dedicated or suitable wiper blades and replace them in time to prevent scratching the front windshield. Keep the windshield clean regularly. If debris is stuck, avoid using the wiper to remove it; instead, carefully wipe it off with a towel or other tools. Use automotive-specific glass cleaner to maintain clear visibility, increase lubrication, and reduce wear on the windshield.
After driving for several years, I've noticed that most of the pitting on the windshield is caused by small stones kicked up from the road. Especially on highways, gravel flung by the tires of oncoming vehicles impacts the glass surface, leaving tiny pits that become noticeable over time as they accumulate. Additionally, frequent parking in dusty areas can accelerate wear, and if the glass itself is of poor quality or aged, it becomes even more vulnerable. To minimize this, I recommend applying a glass protective coating, maintaining a safe distance from other vehicles while driving, and avoiding the use of hard objects when cleaning to prevent exacerbating the issue. For severe pitting, it's best to seek professional polishing services; otherwise, visibility can be significantly reduced in sunlight or rain, posing serious safety risks.
Environmental factors are indeed the main cause of windshield pitting. I feel that in industrial areas or regions with frequent acid rain, the glass is more prone to corrosion, leading to small pits. Pollutants gradually erode the surface, almost like peeling off a layer. Near my home, there are factories, and the rainwater has high acidic content. If I don't wash the car promptly after the rain stops, the pits accumulate quickly. This is directly related to air quality and rainwater composition. It's advisable to choose acid-resistant windshield models or apply regular waxing for protection. Long-term neglect can lead to increased pitting, which affects nighttime driving visibility. Dealing with it later can be costly and not worthwhile, so maintaining cleanliness is crucial.
