Can I add water if the windshield washer fluid runs out?

[DelFinley]

You can add water if the windshield washer fluid runs out, but it is better to use windshield washer fluid because adding water can easily produce scale and clog the nozzles. Windshield washer fluid is made of deionized water and various environmentally friendly additives, which have functions such as cleaning, antifreeze, antistatic, and anti-corrosion. Some higher-quality windshield washer fluids also have properties like rapid snow and ice melting, anti-glare, and anti-fog, which play a significant role in improving driving safety. After cleaning the windshield, the washer fluid will flow near the air conditioning intake, and the volatile odor of the washer fluid will enter the cabin through the car's air conditioning ventilation ducts. The volatile gases from inferior-quality washer fluids are harmful and can become an invisible killer that threatens the health of car owners.
