    Best Windshield Washer Fluid Reviews & Recommendations 2020

    Best Overall

    While most windshield washer fluids are designed for your reservoir, the Rain-X windshield washer fluid is an additive that can be diluted in either water or your choice of antifreeze or alternative washer fluid. Rain-X is one of the best windshield washer fluids for protection against dirt and bugs. When water comes into contact with your vehicle’s windshield, it turns into tiny beads. This makes the rainwater run off the windscreen smoothly, improving your vision in the rain.


    This product has been manufactured to work like wax, but for glass. It gives your vehicle a beautiful, shiny finish that helps make your car look great. You can also use this product on plastic surfaces like headlight castings to get rid of haze and dirt. It is sold in a 16.9-fluid-ounce bottle. The manufacturer recommends mixing 4 ounces of the solution with water.


    While the Rain-X washer fluid makes it easy to add a protective coat on your vehicle’s windshield, it won’t last as long as other options. This product is also not very useful when it comes to stopping the washer fluid from freezing. You might need to add 90-percent-proof alcohol to improve its freezing resistance at low temperatures.

    Best Value

    This premium formula windshield washer works on a number of levels. It removes bugs, bug residue, and road grime in warm weather. It also de-ices your windshield in winter. 


    This windshield washer from Prestone works down to -27 degrees Fahrenheit so you can drive safely in the cold weather. The beading technology does not allow any streaks, which keeps your windshield clean and clear in all four seasons. This is a reasonably priced product that does the job well.


    Note that you cannot lawfully use this product in Texas or California. The product can be a little too strong, as it removed some paint on one user’s truck. The odor can be a little too strong and in one case, the fluid froze up at 30 degrees Fahrenheit.

    Honorable Mention

    The Nextzett Kristall Windshield washer fluid is an ultra-concentrated formula with about 200 times more concentrated than other liquids on the market. It is perhaps one of the most durable screen washers that offer the best value. The Nextzett windshield washer fluid delivers high performance removing dirt, road grime, and bugs. It also eliminates glare from your vehicle’s glass offering enhanced visibility while driving. 


    With its 8.5-ounce bottle, you can refill about five smaller washer bottles. Unlike most concentrated washer fluids, this product is designed with water softeners that prevent your vehicle’s water jets and hoses from clogging. It is also safe to use on plastic surfaces such as your headlights and won't harm the sensors in the containers. This product is non-toxic and has been made from the biodegradable and phosphate-free formula.


    One drawback is that the product has a very strong scent, even though the company claims it is ammonia-free. It is also a bit complicated trying to get the ratios right, in case you miss the right concentration proportions, it could ruin your reservoir. This product also lacks water beading characteristics and will not improve your vision during a storm.

    Honorable Mention

    If you're looking for an inexpensive alternative, the 303 Products windshield washer might be an excellent choice for you. It's a super-concentrated product that has up to three times more cleaning power than regular washes. With it, you'll be able to clean and maintain your windshield for quite some time.


    The thing that makes this product unique is the fact it comes in tablets. You'll get 25 tablets in a pack, and each one makes one gallon of cleaner. All you need to do is to let the tablet dissolve in water and you'll be able to remove bugs, road film, dirt, and grime.


    The product is non-toxic, biodegradable, and safe to use on rubber and paint. That means it won't leave any residue or harm your vehicle in any way. You can use it whenever necessary and keep your windshield clean and well-maintained.


    However, don't forget that this is a budget-friendly product, so it might not be of ultimate efficiency. The main drawback comes from the fact that it doesn't fully remove bug messes. If you need a heavy-duty windshield washer fluid, you might need to look for other options. Also, the product doesn't have antifreeze capacity, so you'll need to mix it with a proper solution for during the winter.

    Honorable Mention

    This is one of the most favored windshield cleaning products among BMW owners. It's a powerful and super safe cleaner that allows you to remove dirt, bugs, and all kinds of residue from your windshield. It's also cost-efficient and lasts.

Also, you can apply it in a breeze. Even complete beginners can do it thanks to the included instructions. What's even more important, this windshield washer fluid is incredibly efficient and leaves the vehicle sparkling clean.


    There are a few things to keep in mind with this product, though. Firstly, the mixing ratio might go a little off during the winter. You'll probably need to use less or more liquid depending on the outside temperature. Secondly, some buyers complained about the lack of smell. If you want something to leave a pleasant smell after the application, this might not be an ideal option for you.

    Honorable Mention

    Those who are searching for a long-term solution to cleaning their windshield might find Aqua Charge perfect for their needs.

    However, the liquid leaves a blue dye, so make sure to wear work gloves, and handle it carefully to avoid accidental spills on your floors. It won’t leave any residue on the glass, but other materials are likely to get ruined. Also, it might be quite challenging to find a way to measure and pour the right amount of liquid and dissolve it in water. Make sure to tighten the cap after every use and store the product in an upright position to avoid leaks. 

    Honorable Mention

    Still, make sure not to use the product under direct sunlight because it might streak and leave a hazy film on your windshield. Another drawback is that this product doesn't really repel rain, regardless of the description on the bottle. It will leave a protective coat, but not quite a water-repellent one.

    Honorable Mention

This particular windshield washer fluid is one of their most popular products and is known to deliver excellent results.

Also, some buyers noticed that the liquid left some stains on their hands and surfaces other than glass.

    Honorable Mention

    The Nanoskin additive is a product you can add to washer fluids and glass cleaners to enhance their performance. It's an incredibly useful liquid that enhances the overall visibility and makes the windshield glass sparkling clean.


    The mixing ratio goes at about four caps of the additive to one gallon of washer fluid and glass cleaner. Considering a little of the liquid goes a long way, it's a cost-efficient option that will last for quite a while. Furthermore, the formula is very efficient and helps remove stubborn residues, road grime, bird droppings, and other debris. Although quite powerful, it's still safe for glass and won't damage your vehicle.


    However, keep in mind that the product is not quite heavy-duty. If you need something for removing persistent stains and heavy dirt, this is probably not going to cut it. Also, the windshield washer repels water but not that efficiently. Depending on the vehicle type, application, and weather conditions, you'll see a difference in cleaning results.

    Key Features

    Water-Beading Results 

    It's important to note that windshield cleaners won't repel water but will encourage water to bead on the surface of your vehicle’s windshield. Essentially, this helps keep rainwater in big fat drops that run off the surface. This makes your wipers work more effectively, improving your vision while driving in poor conditions.

    Bug Repellent 

    The best windshield washer fluids have bug-repellent adhesives and compounds. These ensure that your vehicle’s windshield does not attract bugs. It's common to have bugs splatter on your windshield when driving. Getting rid of them can end up being a sticky mess. Purchasing a windshield washer with bug-repelling compounds will create a surface that will prevent insects from sticking. 

    Streak-Free Finish 

    Having streaks on the glass after cleaning ruins a vehicle’s look. The best windshield washer is one that does the job without leaving streaks behind.

    De-Icer

    When it’s freezing outside and you’re on the road, you want a windshield washer that removes ice and snow so you can see where you’re going. A premium windshield washer does this and removes bugs and grime in warm weather as well.

    Other Considerations

    • Dilution Ratios: Depending on whether you are buying concentrated or crystal windscreen washer fluid, it is important that you follow the instructions about dilution ratio based on the type of climate area you live in. Otherwise, the washer fluid might end up getting too sticky to remove or might result in an excessive haze.
    • All-Season Products: There are quite a number of washer fluid products available on the market. Each product is formulated for a specific climate. However, if you find dilution ratios a little complicated, you may opt for all-season options instead. These products maintain their liquid form in both warm and cold climates.

    Tips

    • It’s important that your windshield wiper fluid reservoir is filled to the correct level. Make sure you regularly check your liquid level using the indicator. A good rule of thumb is to check the level of your windshield washer fluid every time you clean your car.
    • Avoid filling the wrong reservoir. Depending on the make of your car, the wiper fluid reservoir and the coolant reservoir might be a bit confusing. The biggest difference between the two is the coolant reservoir has a tube leading to the radiator. 
    • Carefully read the washer instructions. All washer fluids are different; some need to be diluted, while others are good to go. Some washer fluids are better for cold climates, while others are good for warmer climates. 
    • Keep a spare container around. It’s always better to be prepared. Carrying a spare container of windshield washer fluid in your trunk could come in handy when you run out driving in rain or snow. 

    FAQs

    Q: Why can’t I use water?

    A: Water doesn’t have any cleaning properties that can tackle, dust, grime, bird droppings, or tree sap. In case you use water and encounter bird droppings or bug residue, it will just smear it all over the windshield, further worsening your visibility.

    Q: What’s in windshield wiper fluid?

    A: Depending on the manufacturer, products will have different ingredients that are mixed to specific ratios depending on the formula. Windshield washer fluid will likely have ethanol or methanol, depending on its purpose.

    Q: How do I add windshield fluid to my car?

    A: The first thing you need to do is read the instructions. Find the correct reservoir, open the lid, and fill it up, making sure it matches the indicator. It should be marked with a Maximum Fill Line.

    Q: What should I do if the washer fluid is frozen in my reservoir?

    A: If you trigger the windshield washer button and nothing happens, do not force it, especially if you suspect the washer fluid is frozen. It could damage the whole system. You will have to wait and check for leaks once it has thawed. Repair the pipes or the reservoir.
