How to Deal with Water Stains on Car Windshield?
2 Answers
Just like the car itself, from a distance it may look fine, but up close it can be particularly uncomfortable, especially with certain paint colors where it's very noticeable. The coating or wax layer is damaged. The car paint surface is compromised. Chemical corrosion. The paint film was exposed to rain or water droplets before it had fully hardened. Traces left after water droplets evaporate. When the chemicals in the water marks are heated by sunlight on the car body, they react chemically with the car paint. Use toothpaste to clean the car body: apply an appropriate amount of toothpaste to the water stains, then wipe with a soft towel, repeating several times, and rinse with water.
As a daily commuter who drives to work, I often encounter windshield water stain issues, especially after rain or car washes. The solution is actually quite straightforward: first, use the windshield washer fluid and wipers a few times. If water marks still remain, simply purchase a bottle of glass-specific cleaner from the supermarket, spray it on, and wipe clean with a microfiber cloth. For stubborn stains, try a homemade vinegar-water solution—one tablespoon of white vinegar mixed with two tablespoons of water—which works quite well and can save some money. Additionally, water stains are mostly mineral deposits left behind by evaporated hard water, so it's important to regularly rinse the glass with clean water and wipe it at least once a week. For prevention, try to avoid parking under trees or in dusty areas, and using high-quality washer fluid can also reduce water stain formation. A dirty windshield affects safe driving, so I always check it before every highway trip to ensure clear, streak-free visibility.
