What Is Windshield Wiper Fluid?

Windshield wiper fluid is a cleaning fluid made for your car windshield glass. The basic formula includes ethanol or methanol to clean the surface, along with ethylene glycol to prevent freezing. However, you can also find a number of specialized formulas for summer, winter, and all-seasons. These formulas may contain additives like antifreeze or rain repellant chemicals, which can fine-tune your performance in different weather conditions. 

How to Use Windshield Wiper Fluid

Learning how to use windshield wiper fluid is simple. Most cars have a button on the windshield wiper lever that dispenses the fluid with just a tap. Your owner’s manual will provide information for your specific make and model, or you can ask our technicians for help.

If you notice any dirt on your windshield, just press the button to dispense wiper fluid from the nozzles on your windshield. The wiper blades will automatically get to work, sweeping away any debris in the process. We also recommend cleaning the inside of your windshield from time to time with glass cleaner and rubbing alcohol. This will give you the best clarity possible on the St. Charles roads!

Where to Put Windshield Wiper Fluid

So, how do you refill your supply? Learning how to refill windshield wiper fluid is easy as long as you know where to look. Your car will flash a warning light when it’s time for a top-off. When you see it illuminate on your dashboard, just follow these steps: 

1. Look for the windshield wiper fluid reservoir. It’s usually located near the engine, but check your owner’s manual for assistance.
2. Remove the reservoir cap, and place it somewhere safe.
3. Pour fluid into the reservoir until you reach the fill line. Using a funnel can make the process easier.
4. Replace the reservoir cap.
