Whether you have winter wiper blades or not, you need to make sure that you have fluid in your wipers. At the same time, you want to make sure the type of wiper you use has a low freezing temperature for the winter so that it can be useful.
One of the reasons that the winter wiper blades need windshield wiper fluid is that you are going to be unable to clean off your windshield without wiper fluid. In the winter, you are going to have a bunch of ice and sludge on your windshield. This makes the fluid necessary.
Another issue you have to worry about without wiper fluid is the wear on the windshield wiper blades. Without wiper fluid, the windshield wiper blades are going to wear out a bit more quickly than with windshield wiper fluid. Therefore, the right type of windshield wiper fluid is recommended.
