To remove fog inside the car on rainy days, you can turn on the air conditioning cold air. Below are some precautions for driving in the rain: 1. Reduce overtaking: Because the steering wheel becomes more flexible and harder to control in the rain, drivers should stay within their designated lanes and minimize lane changes. It's best to avoid overtaking on narrow roads, as it can easily lead to skidding. Instead, follow the vehicle in front and avoid showing off. 2. Check the condition of the wipers: Rainy days often have poor lighting, and rain hitting the windshield can further impair visibility. If the wipers are faulty, it will be impossible to clear the water mist from the front windshield, significantly affecting the driver's ability to see and compromising overall safety. Therefore, it's essential to check the wipers in advance.

When driving in the rain, I often encounter foggy windows inside the car, and the blurred vision is really frustrating. I usually start with the quickest method: pressing the defogging button inside the car, which typically adjusts the airflow direction and fan speed automatically. If there’s no button, I manually turn on the AC, set the fan to medium or high speed, and direct the airflow toward the windshield. Cold air defogs incredibly fast, showing results in less than a minute, but it can make the car chilly, so I adjust the temperature to a comfortable level afterward. Prevention is also key—for example, keeping a car defogging spray handy and applying it to the glass surface once a month reduces dirt buildup, making fog less likely to form. Fogging on rainy days mainly occurs due to humidity inside the car and the temperature difference with the outside, so before driving, I check the window seals to ensure no rain leaks in. Regular maintenance saves a lot of hassle. Safety comes first—if fogging occurs, I slow down gradually and avoid fiddling with settings while driving.

Can Tap Water Be Used as a Substitute for Windshield Washer Fluid?

Tap water cannot be used as a substitute for windshield washer fluid. Windshield washer fluid, also known as glass cleaner, is commonly referred to as the cleaning solution for a car's windshield and is considered a consumable item in vehicle maintenance. High-quality windshield washer fluid primarily consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Functions of windshield washer fluid: 1. Anti-freezing properties: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing anti-freezing effects and quickly dissolving frost. 2. Anti-fogging properties: It forms a monomolecular protective layer on the glass surface, preventing the formation of fog droplets and ensuring clear visibility through the windshield. 3. Anti-static properties: After cleaning with washer fluid, substances adsorbed on the glass surface eliminate static charges, offering anti-static benefits. 4. Anti-corrosion properties: The fluid contains multiple corrosion inhibitors, ensuring no corrosive effects on various metals, and is absolutely safe for car paint and rubber.
