Can You Use Water For Windshield Washer Fluid?

Replacing your windshield washer fluid should not be a complicated maintenance task for anyone. Does it matter what kind you use? And can you use water in place of it? We'll get down to the bottom of these burning questions today.

To answer the latter question: No, you should not use water when refilling your windshield washer fluid. One common mistake that drivers often make is filling the reservoir with water when they're in a pinch or don't want to bother going to the store. While the water might give you satisfactory results in warmer weather, what about in the cold, freezing winter? That's the problem with water; it will freeze up inside your tank and fluid lines, causing damage to the system altogether.

Another problem with using water as your windshield fluid is bacteria. The water in the reservoir can grow microbes and make you sick when you trigger your washers. Therefore, you should never compromise by adding water to refill your washer fluid. Please ensure you use a solution that contains a small amount of alcohol to prevent breeding freezing and bacteria growth in your fluid lines.

Is There Such Thing As Winter Windshield Fluid?

If you live in a harsh and cold climate, you should consider investing in a high-quality solution with anti-freezing properties. Most windshield washer fluids will have a label indicating their operating temperature range. So please be wary of that information when shopping for windshield wiper fluid.

Since the weather can be pretty unpredictable in Canada this time of year, we recommend you carry an extra bottle of windshield washer fluid in your car. It will give you extra confidence no matter rain, sun, or snow in Oakville, ON.
