How is water removed from a car's windshield?

It can be eliminated through the defogging function of the air conditioning system. The role of the cabin air filter has the following 3 points: 1. Provide fresh air: Prevents the car windows from fogging up, ensuring clear driver visibility and driving safety; Supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; Effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: Maintains clean cabin air without bacterial growth; Effectively separates solid impurities such as dust, filter powder, and grinding particles from the air; Effectively blocks pollen to prevent allergic reactions that could affect driving safety. 3. Adsorb harmful substances: Adsorbs moisture, soot, ozone, and odors from the air, with strong and long-lasting moisture adsorption capabilities.

I've been driving for decades, and the water removal on the windshield primarily relies on the wiper system. The wiper uses a small motor to drive the blades back and forth, sweeping rainwater to the sides during rain. On sunny days, I also use the wipers to clean dust and insect stains, ensuring clear visibility. Besides wipers, the defogging function of the air conditioning is crucial. Pressing the windshield defogging button directs hot or cold air directly onto the inner surface of the glass, quickly evaporating condensation. If the rain is too heavy, the wiper speed can be adjusted—low speed for light rain, medium for moderate rain, and high for heavy downpours. I also apply a hydrophobic coating to the glass, which causes rainwater to bead up and roll off easily, reducing wear from frequent wiper use. Regular maintenance is essential: replace wiper blades every six months to prevent aging and breakage, and choose windshield washer fluid with an oil-film-removing function. These methods ensure driving safety by keeping the view unobstructed by water.

When encountering water on the windshield while driving daily, safety is my top priority. Turning on the wipers immediately clears the water. The operation is simple: just press the button near the steering wheel. The wiper speed can be adjusted to a suitable setting. The air conditioning defogging function is also highly efficient; pressing the defog button directs airflow to the windshield, drying it in seconds. For water on the outside, the wipers handle it; for fogging on the inside, using the air conditioning or slightly opening the window for ventilation works. Preventive measures include regularly cleaning the glass surface, using glass cleaner when washing the car to reduce oil film, and checking that the wipers aren’t stuck. Driving slowly in the rain ensures good visibility and safety. These small tips are both convenient and reliable, and sharing them with my family has proven effective. New drivers should practice more to familiarize themselves with their car’s controls.

There is water on my car's windshield, so I use the wipers to remove it; the wipers sweep back and forth, and the water is pushed to the sides. Regular maintenance is crucial: keep the wiper blades clean to extend their lifespan; ensure the windshield washer fluid is full for better water removal. Occasionally, if fogging occurs, use the air conditioning's defogging function. Simply wiping the glass can also help—use a soft cloth dampened with water when parked. During car washes, clean both the inside and outside to prevent dirt buildup.
