What are the small dots on the car windshield?
4 Answers
The small dots on the car windshield serve purposes such as sunshading, protecting the front windshield, and beautifying the edges of the car glass. Below are the functions of these small black dots: 1. Protecting visibility: They help reduce glare from sunlight, enabling the driver to maintain clear vision while driving. 2. Protecting the windshield: When sunlight directly hits the windshield, it causes thermal expansion and contraction. The small black dots help mitigate this effect by reducing the intensity of direct sunlight on the windshield. 3. Decorating the car: The small black dots also serve an aesthetic purpose, making the edges of the car glass look less plain and more visually appealing.
I've been driving for over 30 years and have seen plenty of those little dots on windshields. The most common are stains left by insect remains or bodily fluids, which get splattered on during high-speed driving and can cause glare in sunlight, affecting visibility. There are also stone chips—small dents created by flying gravel that trap water during rain, further blurring the view. Water spots are another frequent issue, where mineral deposits from car washes or rain dry into white specks. I regularly clean my windshield with neutral detergent and water, applying toothpaste for gentle scrubbing on stubborn stains, followed by rain repellent to prevent buildup. Remember, safety comes first—don’t wait until those dots cause an accident; address them promptly.
As a novice driver, I find those tiny spots on the windshield quite annoying. My friend told me they're marks left by insects hitting the glass, or sometimes small white stains from dried water spots. I figured out a solution myself: mix white vinegar and water in a certain ratio, spray it on and wait a few minutes for softening, then wipe it off with a soft cloth. Car washes can also handle it quickly without costing much. For prevention, I wash my car frequently and avoid parking under trees to prevent resin or bird droppings from splashing onto the glass. Although these small stains may seem insignificant, they can cause glare and obstruct vision during rainy drives, so it's important to keep the windshield clean for safety.
I enjoy DIY car maintenance in my spare time. Windshield spots generally fall into three categories: bug stains, hard water spots, or minor impact pits. For materials, use common household items - mix white vinegar and warm water 50/50, spray on the spots and wait ten minutes to dissolve the stains, then wipe clean with a soft cloth. For small pits, simply apply glass repair compound to level them. Avoid using scrapers to prevent scratching. After cleaning, apply a layer of water-repellent spray to prevent new stain accumulation. Simple DIY saves time and money, but the key is regular maintenance to ensure continuous visibility protection for safe driving.
