While it may be tempting to refill windshield wiper fluid with water, it is generally not recommended. Windshield wiper fluid is specifically designed to clean your car's windshield effectively and safely. It contains special additives that help remove dirt, bugs, road grime, and other debris from the glass without damaging the surface or the wiper blades.
Using water instead of windshield wiper fluid can have several drawbacks:
Ineffective cleaning: Water alone may not effectively remove all the dirt and grime, especially in tough weather conditions or when dealing with stubborn residue.
Freezing in cold temperatures: In colder climates, water can freeze and damage the washer system, including the reservoir, hoses, and even the wiper nozzles. This can lead to costly repairs.
Corrosion: Water can promote corrosion in the washer system components over time, potentially leading to leaks and other issues.
Reduced visibility: Using plain water might leave streaks on the windshield, compromising visibility and increasing the risk of accidents.
Instead of water, use a proper windshield wiper fluid recommended by the vehicle manufacturer. These fluids are readily available at automotive stores and gas stations. They are designed to work in various weather conditions and are less likely to cause issues with your washer system. If you're in a pinch and can't find the right fluid, it's better to wait until you can get the correct product rather than using water as a temporary solution.
