At what temperature does summer windshield washer fluid freeze?
1 Answers
Summer windshield washer fluid will freeze at around 0°C because it does not contain antifreeze substances. Most summer formulas primarily consist of insect-removing agents, which help quickly eliminate small insects on the windshield. If the temperature drops and you still have summer washer fluid remaining, it is best to completely drain it and replace it with winter-grade antifreeze washer fluid to avoid affecting normal driving. Below are the functions of windshield washer fluid: 1. When the transparency of the front windshield decreases, spraying washer fluid can restore a clear and bright field of vision. Especially during nighttime driving, dust on the glass can scatter light, making it necessary to spray washer fluid to maintain the windshield in optimal transparency. 2. Windshield washer fluid also has anti-fog properties, forming a monomolecular protective layer on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent for optimal visibility. 3. Washer fluid also has anti-static properties, eliminating surface charges on the glass. Its corrosion-resistant formula contains various inhibitors that are completely safe for all metals, automotive paint, and rubber components.
