0-degree windshield fluid will freeze when the temperature drops below zero in winter. This type of fluid is designed for environments above 0°C, and under normal circumstances, using 0-degree windshield fluid in sub-zero temperatures will cause it to freeze. For northern winters, it is advisable to choose anti-freeze windshield fluid to prevent damage to the vehicle caused by frozen fluid. Automotive windshield fluid is widely used for quick cleaning and brightening of car windows, rearview mirrors, as well as household, office, door, window, and decorative glass. It is made from deionized water and various environmentally friendly additives, offering functions such as cleaning, anti-freeze, anti-static, and anti-corrosion.

Using 0-degree windshield washer fluid in winter can indeed freeze, which I've encountered several times. Once while driving at -3 degrees Celsius, I suddenly couldn't spray water and realized the washer fluid had frozen, leaving the windshield covered in dust, forcing me to pull over urgently. Later, I learned from experience that 0-degree antifreeze is only reliable above freezing; below zero, the water crystallizes and blocks the pipes, preventing spraying. The solution is to temporarily use warm saltwater to slowly thaw it or wait for the car to warm up. To avoid trouble, I now check the local minimum temperature in advance. If sub-zero temperatures are forecast for several days, I switch to -15-degree windshield washer fluid, making winter driving much more worry-free. Developing the habit of checking and topping up the fluid level before winter prevents mid-journey mishaps and delays.

From a technical perspective, it's normal for 0-degree windshield washer fluid to freeze in winter because the antifreeze additives can only prevent freezing above zero degrees. Once the temperature drops below the labeled rating, water molecules will crystallize and solidify. This is similar to how regular water freezes in a refrigerator - when the concentration of washer fluid components isn't high enough, the freezing point won't drop significantly. When selecting washer fluid, I always consider local climate conditions. In colder regions, -15 degree or lower-rated products must be used. Additionally, frozen fluid may expand and damage the container, increasing maintenance costs. Therefore, it's advisable to drain old fluid and replace it with new antifreeze during seasonal transitions to ensure driving safety and save on repair expenses.

If the 0°C windshield washer fluid freezes in winter, don't rush to force the spray as it may damage the pump. First, check the temperature - if it's below freezing, the fluid is likely frozen. The solution is to park the car indoors until temperatures rise, or carefully thaw the pipes using lukewarm water. For prevention, it's recommended to switch to a higher freeze-resistant washer fluid based on winter habits. For example, friends in northern regions should opt for -25°C fluid. Regularly check the reservoir fluid level and keep it full to minimize air impact. Simple maintenance can prevent many troubles.
