What are the effects of not adding windshield washer fluid to a car for a long time?

No impact. Extended information: The functions of windshield washer fluid: Anti-freezing performance: The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, thereby providing anti-freezing effects and quickly dissolving frost. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision. Anti-static performance: After washing the windows, substances adsorbed on the glass surface can eliminate surface charges, providing anti-static properties. Lubrication performance: The ethylene glycol in the washer fluid has high viscosity, which can lubricate and reduce friction between the wiper and the glass, preventing scratches.
Having driven for over a decade, I fully understand the importance of windshield washer fluid. Prolonged failure to replenish washer fluid can cause wiper blades to dry-rub and age prematurely, especially when wiping dust, which shortens the blade lifespan. The spray nozzles also accumulate deposits and clog—once I noticed weakened spray flow and found them crusted with scale when disassembled. In summer, insect remains plastered on the windshield can't be cleared with plain water, leaving a blurred view while driving. Winter brings worse troubles—using water instead risks cracking the reservoir if frozen. Most critically, uncleaned windshields during emergencies obstruct visibility; rainy-day mirror reflections become dangerously unclear without proper fluid. Now I always keep two bottles in my trunk for instant top-ups—peace of mind guaranteed.
Many novice drivers in our community think windshield washer fluid is unimportant, only to regret it later. I've seen a neighbor's car with the entire windshield covered in insect residue, the wipers screeching, and eventually having to replace the rubber blades. Long-term neglect of washer fluid can cause the pump to burn out from dry running, costing 200-300 yuan to repair. Sediment can also accumulate at the bottom of the reservoir, clogging the lines and being difficult to clean. Especially for those in northern regions, antifreeze washer fluid is essential—tap water can freeze and crack plastic components, requiring bumper removal for replacement. Even worse, oil film on the windshield won't clear properly, creating dangerous glare when driving at night. This isn't something to be lazy about; regular checks of your washer fluid are a must.
