Q: Can I use water instead of windshield washer fluid?
A: It is not recommended to use only water. Remember, water freezes at 32 degrees Fahrenheit. If you live in an area that the temperature gets below freezing, you will risk cracking your car’s windshield washer reservoir and pump. Windshield washer fluid is formulated to protect against freezing and has chemicals to clean road grime from the windshield.
