At What Temperature Does Summer Windshield Washer Fluid Freeze?
2 Answers
Summer windshield washer fluid will freeze below 0°C as it doesn't contain antifreeze components. Below is an introduction to three types of washer fluids available on the market: 1. Summer windshield washer fluid: With a freezing point around 0°C, this type contains insect-cleaning agents that can remove bugs and tree sap from windshields. 2. Antifreeze windshield washer fluid: With a freezing point of -20°C, this type can be used when outdoor temperatures drop below -20°C without freezing or causing pipe cracks. 3. Special antifreeze windshield washer fluid: With a freezing point of -40°C, it remains unfrozen even at -40°C, making it suitable for extremely cold regions in northern China.
The freezing point of summer windshield washer fluid typically starts at below zero degrees Celsius, with significant variations between brands, commonly ranging from -3°C to -8°C. Having driven for over a decade and used many brands, I've found that cheaper options from supermarkets may freeze at -2°C, while slightly better ones can withstand up to -5°C. Once during a trip, I forgot to switch to winter fluid, and when the temperature dropped to -10°C at night, the nozzles froze and couldn't spray water, leaving my vision blurred while driving and nearly causing an accident. This product is designed to remove dust and insect residue, with low antifreeze content, unlike winter products that can handle lower temperatures. When choosing, pay attention to the freezing point marked on the bottle—reputable manufacturers clearly indicate it—and avoid buying cheap, inferior products. Storage conditions also affect its lifespan; keeping it in the trunk where it's exposed to heat may reduce effectiveness. It's suitable for temperate summers, but remember to replace it before cold spells to minimize risks as a habit.
