Best Windshield Washer Fluid: De-Icing, Seasonality & More
A clean windshield is vital to your safety, ensuring an unobstructed view of whatever lies ahead. The best windshield washer fluid not only clears your windshield of bugs and road debris but is also biodegradable and stays liquid in colder temperatures.
Explore the best windshield washer fluid products below and discover how to choose one that best suits your environment.
What Are the Main Types of Windshield Washer Fluid?
Before you select the windshield washer fluid that best suits your demands, it’s important to recognize the differences between each of the windshield washer fluid types in the automotive industry.
Although water can help wash your windshield in a pinch, it doesn’t contain the same properties as washer fluid regarding cleaning properties, freeze point, and so on. However, the type of windshield washer fluid you choose depends on your climate, budget, and preferred features.
Basic Washer Fluid
Standard windshield washer fluid works well in warmer climates that typically don’t experience much precipitation or freezing temperatures. Basic washer fluid contains methanol (about 30%–50%), water, and detergents.
However, this type of washer fluid does not contain antifreeze, so it will begin to get slushy at around 32 degrees Fahrenheit.
Bug Removal Washer Fluid
As the name suggests, this washer fluid type targets the numerous bugs unfortunate enough to meet their untimely end on your car’s windshield.
Many drivers fill their windshield washer fluid reservoirs with this type of washer fluid during the spring and summer when bugs are most prevalent. Bug removal washer fluid contains more detergents than methanol and antifreeze.
As such, bug removal windshield washer fluid isn’t an ideal choice for climates with low temperatures and heavy precipitation patterns. However, that’s not to say washer fluid types that are suited to lower mercury levels lack a bug removal detergent. In fact, many de-icing washer fluid formulas incorporate bug-removal detergents, especially if they’re multipurpose.
Water-Repelling Washer Fluid
Windshield washer fluid that repels water performs well in climates where precipitation falls year-round. The water-beading action creates a hydrophobic layer on the windshield’s surface. With less water to remove from the windshield, drivers can use their wipers less, reducing the chances of windshield streaking.
All-Season Washer Fluid
Best for year-round use, all-season washer fluid can perform well in areas with mild to moderate precipitation annually. Equipped with anti-freezing and bug-cleaning capabilities, this windshield washer fluid is a slight upgrade from standard windshield washer fluid.
De-Icing Washer Fluid
Washer fluid suited for extremely cold temperatures requires methanol or ethylene to maintain its anti-freezing properties. Otherwise, any washer fluid in the reservoir, lines, or spray nozzles would freeze solid.
De-icing washer fluid contains detergents that remove road salt, mag-chloride, and other road debris, in addition to surfactants that reduce surface tension for a cleaner windshield altogether.
What Is the Best Windshield Washer Fluid?
With the best windshield washer fluid in your car, you can approach whatever lies ahead with a clear line of sight. Below are the best solutions to a dirty windshield from brands like Rain-X and Peak. Which will you choose?
Best All-Purpose: Peak Windshield Wash and De-Icer
Peak Windshield Wash and De-Icer is a ready-to-use formula that’s rated to a temperature of -20 degrees Fahrenheit. This light blue-colored solution features cleaning and de-icing properties that make it a superb choice for all-purpose use.
Best Heavy-Duty De-Icer: Rain-X Heavy Duty De-Icer Windshield Washer Fluid
If you live in an area of the country that sees above-average precipitation, Rain-X’s Heavy Duty De-Icer Windshield Washer Fluid contains the same water-repelling agent that built the brand’s reputation. This heavy-duty windshield washer fluid is rated for -25 degrees Fahrenheit.
Best Concentrate: nextzett Kristall Klar Washer Fluid Concentrate
Purchasing windshield washer fluid in concentrate can save you money in the long run, especially if you’re comfortable diluting the product yourself. Once diluted, this 8.5-ounce bottle of concentrate produces nearly 13 gallons of washer fluid, with one ounce per 1.5 gallons of water.
Best Tablets: 303 Instant Windshield Washer Tablets
Similar to the nextzett windshield washer fluid concentrate, 303’s Instant Windshield Washer Tablets come in a concentrated form. Each of the 25 tablets dissolves in a gallon of water, but this formula isn’t necessarily the best for areas of heavy rain or snowfall.
What To Look For in Windshield Washer Fluid
Windshield washer fluid formulations contain various features, but knowing which ones to pay attention to can help you make a more informed decision.
The windshield washer fluid features below make for a better overall user experience:
- Dilution vs. concentration: Windshield washer fluid comes premixed and ready to use or concentrated.
- Freeze protection: Although windshield washer fluid will become slushy before it freezes completely, a lower freeze point ensures you have fluid if necessary.
- Compatibility: Most windshield washer fluids are compatible with modern vehicles of many makes and models.
- Color and odor: Washer fluid containing alcohol has a certain smell, but the specific coloring agent depends on the brand.
Windshield washer fluid is typically available at auto parts stores, gas stations, or larger retailers. You can also order a particular product or formulation online. If you purchase washer fluid in bulk, it will last a few years if stored properly.
