Is there any impact if the windshield washer fluid is completely empty?

If a car runs out of windshield washer fluid, it does not affect the vehicle itself. However, if the washer function is used for a long time without fluid, the washer pump may run dry and could potentially burn out. Windshield washer fluid serves the following functions: 1. Cleaning performance: Surfactants typically have wetting, penetrating, and solubilizing properties, which help clean and remove dirt. 2. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, not only preventing freezing but also quickly melting frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface, preventing the formation of fog droplets and ensuring clear visibility through the windshield. 4. Anti-static performance: After cleaning, substances adsorbed on the glass surface eliminate static charges, providing anti-static properties. 5. Lubrication performance: The high viscosity of ethylene glycol provides lubrication, reducing friction between the wiper blades and the glass, thereby preventing scratches. 6. Anti-corrosion performance: The fluid contains various corrosion inhibitors, making it completely safe for all metals, automotive paint, and rubber.
Running completely out of windshield washer fluid is absolutely problematic, especially for long-haul drivers like us - it's a major hazard. A dirty windshield obscures road visibility, creating high accident risks particularly during rain/snow conditions or at night when sightlines are compromised. Operating empty washer pumps can burn out motor assemblies or clog nozzles, requiring costly replacements that hurt the wallet. Prolonged dry wiper use damages both blades and glass, causing permanent scratches that impair aesthetics and visibility. My advice: Develop the habit of checking fluid levels during every fuel stop, keeping concentrated washer fluid in the vehicle for emergencies. Refill promptly when depleted - never compromise on this safety essential.
