Can I directly add water when the windshield washer fluid runs out?

[Betty]

You can add water when the windshield washer fluid runs out, but it is best to use windshield washer fluid. Adding water can easily cause scale buildup, leading to nozzle clogging. Here is some relevant information about windshield washer fluid: 1. High-quality windshield washer fluid is made from deionized water and various environmentally friendly additives, with functions such as cleaning, antifreeze, antistatic, and anti-corrosion. Some better-quality windshield washer fluids also have features like rapid snow and ice melting, anti-glare, and anti-fogging, which play a significant role in improving driving safety. 2. Inferior windshield washer fluids are mostly made by mixing water and alcohol, which not only damages the gloss of the car's paint and the hardness of rubber strips but can also cause color differences, swelling, and dissolution in rubber or other plastic parts. After cleaning the windshield, the washer fluid flows near the air conditioning intake, and the volatile odor of the fluid can enter the car's interior through the ventilation ducts. The harmful gases emitted by inferior windshield washer fluids can become invisible killers that endanger the health of car owners.
