What Temperature Windshield Washer Fluid Should Be Used in Winter?
2 Answers
In winter, you should choose a windshield washer fluid with a freezing point at least 10°C lower than the local minimum temperature. Here is some relevant information about windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. 2. Antifreeze performance: It can significantly lower the freezing point of the liquid, thus providing antifreeze protection and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision.
I remember when driving in the north during winter, it's essential to choose windshield washer fluid with antifreeze properties, and its freezing point should be at least 10-15°C lower than the local minimum temperature. I usually use fluids rated for -20°C to -35°C, and the brand doesn’t matter much, but the label must clearly indicate the freezing point. Don’t cut corners by using summer fluid rated for 0°C, and avoid mixing different brands, as it can affect performance. When adding the fluid, make sure the reservoir is clean and don’t fill it to the brim—leave some space. If you accidentally use regular washer fluid and the temperature drops, it can freeze and clog the nozzles, making it impossible to clean the windshield, which is a serious safety hazard due to impaired visibility. It’s best to switch to the appropriate fluid in autumn and make a habit of checking the fluid level—it’s both safer and more convenient.
