In the car, the windshield washer fluid button is located on the right-hand stalk of the steering wheel, marked with a water spray pattern. Pressing the stalk inward will spray the windshield washer fluid. Windshield washer fluid, short for car windshield cleaning fluid, mainly consists of: water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. The windshield washer fluid is stored in an independent reservoir in the engine compartment. The steps to add it are: 1. Open the front hood; 2. Open the windshield washer fluid filler cap; 3. Fill the windshield washer fluid up to the marked line. Precautions for using the windshield washer fluid include: 1. Do not spray continuously; spray intermittently; 2. If no fluid comes out when moving the stalk, do not repeatedly move it.

The lever on the right side of the steering wheel is where the windshield washer button is located, and many cars are designed this way. Look for a small fan-shaped spray icon on it. When driving, I usually press this lever toward the steering wheel to activate the washer. If your car model is newer, it might be integrated into the side of the turn signal lever or controlled by a physical button on the multifunction steering wheel. In winter, make sure to use antifreeze windshield washer fluid to prevent the pipes from freezing and blocking the nozzles. Remember to check the windshield washer fluid level regularly, as dry wiping can damage the wiper blades. If the spray is weak, clean the nozzles—usually a fine brush will do the trick. If you can't find the location, refer to the car's manual, which has clear diagrams labeling all control areas.

I often drive cars of different brands and notice that the windshield washer buttons are mainly located in three places. The most common is at the end of the wiper stalk on the right side of the steering wheel, where a simple press or twist does the trick. Some cars, like certain French models, place it on the lower left side of the dashboard. Others integrate it into the multimedia touchscreen, making it a bit harder to find. Don't just play around with it—windshield washer fluid runs out quickly, so keep a spare bottle in the trunk for easy refills. In summer, opt for cleaning-type washer fluid that removes insect residue, and during the rainy season, it ensures clear visibility. If the spray height is insufficient, adjusting the nozzle angle with a needle delivers instant results—even beginners can handle it with ease.

As a car enthusiast, I've studied the control layouts of dozens of vehicles. The windshield washer button is typically marked with a spray pattern on top of the wiper control stalk, where pressing it is most convenient. Japanese cars often use lever operation, while German cars tend to favor rotary knob designs. Some off-road vehicles have independently placed buttons on the front ceiling. Seasonal changes require attention to the washer fluid's freezing point; in northern winters, fluids rated below -25°C are essential. If the washer doesn't spray for extended periods, it might be due to clogged hoses or motor failure—simply inspect the connecting lines yourself. The rear window washer uses a separate button with a wavy line icon, and operations with icons are the most intuitive.
