Does Car Windshield Washer Fluid Freeze?
2 Answers
If the windshield washer fluid used in winter is not specifically designed for winter, it may freeze. Generally, winter-specific washer fluid can prevent freezing at temperatures as low as -20 degrees Celsius. Therefore, it is recommended that car owners choose winter-specific washer fluid during the winter season to effectively avoid freezing, ensuring safer use of windshield wipers and reducing financial losses. When selecting washer fluid for winter, the antifreeze performance should be the primary criterion. If the ambient temperature is particularly low, it is advisable to choose washer fluid with better antifreeze properties to prevent issues such as frozen fluid or malfunctioning of the washer pump. The antistatic performance of car windshield washer fluid is also one of the selection criteria for winter. High-quality washer fluid can prevent the buildup of static charges that attract dirt. If the washer fluid has poor antistatic capabilities, consumers should exercise caution when purchasing to avoid potential inconveniences during use.
Windshield washer fluid can indeed freeze, especially in extremely cold weather. Living in a cold region, I once used plain water as washer fluid, and overnight the reservoir cracked and the nozzles got completely clogged. This happens because plain water freezes below zero degrees, whereas antifreeze washer fluid contains additives like alcohol that can withstand temperatures dozens of degrees below freezing. When choosing, check the freezing point labeled on the bottle—northern regions should use fluid rated for at least -25°C, while southern areas can use standard antifreeze types. Replace it before winter arrives; don’t wait until freezing occurs. A cracked reservoir is expensive to repair and dangerous, and driving with a dirty windshield due to frozen fluid compromises visibility. I now make it a habit to refill with fresh fluid in autumn to ensure safe driving. Remember, the antifreeze formula determines cold resistance—don’t cut corners with cheap products.
