Additionally, using tap water in your washer fluid system provides the ideal conditions for Legionella bacterium to grow. This bacteria causes pneumonia and Legionnaire’s disease. The best winter windshield washer fluid contains antifreeze ingredients that will keep your car in optimal conditions.

… It helps to keep you safe

Road snow and salt can cover your windshield making it impossible for you to see clearly when driving in harsh cold conditions. Inability to see through your windshield either during the day or night is one of the leading cause of car accidents. Drivers can maximize their cars visibility by keeping the windshield free of any obstacles using the right washer fluid.

Which fluid should I choose: premixed or concentrated?

While premixed and concentrated are the two most available forms of windshield washer fluids, the ideal one for you will depend on which is easy to work with and fits your car needs. Either of the two can work for, but during winter it’s crucial to use a solution with de-icer. This is because a de-icer has antifreeze ingredients that help the fluid maintain low freezing temperature.

The Best Windshield Washer Fluid

1. Prestone Bug Wash Windshield Washer Fluid – Best Windshield Washer Fluid

Prestone really nailed it with their Bug Wash Windshield Washer Fluid. This formula has been engineered specifically to help remove bugs from your windshield. Lets face it – bugs are really one of the main reasons you’re needing the best windshield washer fluid in the first place! Even though it only mentions bugs specifically, the best windshield washer fluid on our list also helps wash off bird droppings, road grime, and even tree sap.

With each use you’re going to be putting a layer of bug stopper on your windshield.

Much like most RainX formulas, the Prestone Bug Wash Windshield Washer Fluid also promotes the beading of water, allowing it to flow more freely off your windshield. This greatly improves visibility on the road, and makes your entire drive much safer!

2. Rain-X RX11806D Washer Fluid Additive – Best Windshield Washer Fluid Additive

While it isn’t a true windshield washer fluid on its own, the Rain-X Washer Fluid Additive is definitely the best windshield washer fluid additive on our list. You’ll still need to fill your reservoir with fluid, but after adding this Rain X formula to it you’ll notice a big improvement.

This windshield washer fluid additive will promote water beading on your windshield, which will allow it to flow more freely across it. This prevents the water from “sticking” to your windshield, and you’ll be shocked at how much this improves visibility while driving.  It also helps keep bugs, sleet, snow, ice, and road grime from becoming adhered to your windshield. In other words, this is just as much a preventative measure as it is a windshield washer fluid additive.

3. Prestone De-Icer Windshield Washer Fluid – 

Prestone De-Icer is engineered to improve windshield visibility during winter. It works to remove frost and light ice. Providing a clear and visible view when driving in hazards conditions. As a result, it helps to prevent your windshield from re-freezing and ice forming on your windshield. It contains antifreeze and a formulation that is fast in repelling salt and dirt build up. This Prestone fluid has a freezing point of -27ºF and melts ice three times faster which gives an edge over the others.

The solution will not just keep your windshield clean. It will also create a durable shield that prevents dirt and any road spray from adhering to the glass.

One of the main reasons we selected this as the best winter windshield washer fluid is that it’s safe to use on rain-sensing windshield wipers. Which have become popular on newer model vehicles.

Importance Of Checking Washer Fluid –

One thing that’s often overlooked in the fall is checking your washer fluid reservoir. Most modern-day reservoirs can hold about one gallon of fluid. However, most of the summer there isn’t a large need for wiper fluid other than bugs and dirt on your windshield. Although, as the weather decreases and snow and ice can freeze to your windshield the last thing you want is a washer reservoir that is empty. It can result in a long and highly dangerous situation if you can’t see clearly out your windshield.

How To Fill Your Reservoir –

Therefore, from fall to spring regularly checking your washer fluid weekly is an important vehicle maintenance habit to maintain. To check your washer fluid, open the hood of your vehicle. Then locate the washer fluid cap. Usually, this is indicated with a blue cap or a cap with wiper blades printed on them. If you can’t locate the reservoir check your vehicles owners manual. Next, take the fluid you’ve selected and fill the reservoir up to the fill line. Using an automotive funnel can make this task much easier.

With routine maintenance and checking of your washer fluid, you will prevent the dangers of an icy and frozen windshield while driving.
