1 Answers
Solutions for frozen windshield washer fluid that won't spray out: You can open the reservoir cap and let it thaw in sunlight. If only a thin layer is frozen, it will melt quickly. If it remains frozen, add some warm water to help thaw the fluid. Note that after thawing, you should completely replace the existing washer fluid with a lower-freezing-point formula to prevent re-freezing. Windshield washer fluid is a consumable liquid used for cleaning vehicle windshields, primarily composed of water, alcohol, and ethylene glycol, providing cleaning, antifreeze, and anti-fog functions. By formulation, it can be categorized into solid and liquid types, with most solid variants designed for use above 0°C.
