10 Best Windshield Washer Fluids – Reviews & Ultimate Guide

One of your most important responsibilities as a car owner is to drive safely and keep your car clean. Maintaining a clean windshield is a great part of achieving both of these objectives. To do that, you’ll need a high-quality windshield washer fluid that you can use to clean your windshield regularly.

Waiting to take your car to the car wash before cleaning your windshield could leave you with dust and debris that will interfere with your driving. But, not all windshield washer fluids are made equal. Some formulas are made from highly concentrated quality ingredients, while others are completely ineffective.

It’s also worth noting that it’s best to avoid refilling your reservoir with water when it gets empty because wiper fluid acts as a cleaning agent for your windshield. But, there are a lot of considerations you need to make before you can confidently purchase windshield washer fluid.

To help you along, we’ve written a helpful guide with all the information you need to find the best windshield washer fluid for your needs. We’ll also provide you with a list of the best windshield washer fluids on the market.

Things to Keep in Mind When Shopping for a Quality Windshield Washer

At first glance, it might seem like buying windshield washer liquid is a simple task, but that may not be the case. First of all, there’s a growing variety of options for consumers to choose from nowadays and they all claim to offer the best formula. That’s why we’re going to simplify the process by taking a look at some of the most important features to look out for.

Water Repelling

While a windshield washer fluid won’t be able to expel water onto your windshield spontaneously, it should “spritz” some fluid on the surface. The benefit of this feature is that it improves the effectiveness of your wipers so that rainwater doesn’t leave streaks on the windshield surface. This makes it easier for you to see clearly through the windshield when it’s rainy and cloudy.

Scent

Most of the best windshield fluid products on our list below have a fragrance, typically with a citrus base. This isn’t necessary but if you’re someone that enjoys pleasant fragrances, then you can always go for a lemon-scented windshield washer fluid if you like.

Anti-Freeze

If you live in an area where temperatures frequently go below zero, then you’ll benefit from getting windshield washer fluid that has anti-freeze. It’s worth noting here that you don’t really get anti-freeze technology in diluted products, because the brands add a lot of water to them. But, you can alternatively add 90% alcohol to the mixture to give it that anti-freeze effect.

Dilution

Certain windshield liquid brands offer their product in small and highly concentrated amounts, which allows you to dilute the liquid. That way, you get more bang for your buck and you can add water to your washer fluid reservoir for longer. Of course, a product that doesn’t have to be diluted is easier to use but it doesn’t offer as much value.

Streak-Free Finish

To get a beautiful streak-free finish, opt for a windshield washer fluid that offers effective cleaning.

Why You Should Use a Windshield Washer

Safety

Most car accidents happen when it’s cloudy and raining outside and that’s mainly because of reduced visibility. One of the best ways to fight this problem is to purchase a good quality window washer fluid.

Detailing

Since you’re investing in the improvement of your car’s windshield, you might as well extend the courtesy to your entire car.

Ease of Use

Windshield washer fluids are incredibly easy to use and suitable for anyone. You don’t have to be a petrol head or a DIY ninja to enjoy the benefits because they are incredibly accessible.

Maintenance

Maintaining a clean windshield makes it easier to see spot chips that might turn into a serious issue for your windshield in the long run.

How to Use the Windshield Washer

Whether you’re a self-sufficient individual who likes to do everything yourself or someone who wouldn’t be caught dead near a working tool, adding windshield washer fluid to your car shouldn’t be a problem. But, it can be confusing initially due to certain reasons.

It’s important to start by noting that the windshield washer reservoir is not always located in the same spot in all cars. Plus, there are other fluid reservoirs under the hood of your car that might look like it, which can cause a bit of confusion when the time comes for you to refill it with your windshield washer fluid.

For the best results, head to your car’s owners’ manual to find out where your vehicle’s windshield washer fluid reservoir is located.

Another common problem with finding your fluid reservoir could be the fact that modern cars have complicated looking engines that will make it difficult for an inexperienced person to find the washer fluid reservoir. But as with anything, it is possible to overcome these challenges.

Also, before you add windshield washer fluid to your car it’s important that you clear any obstructions that might get in the way of getting the job done. Double check to make sure that the fluid you’re adding is specially formulated for use on a car windshield. Whatever you do, never add plain water to your windshield washer fluid reservoir because water doesn’t have any cleaning power or anti-freeze ability like a detergent.

Once you’ve checked that everything is in order, you can start by removing the cap covering the reservoir. Depending on the vehicle manufacturer, this might entail unscrewing the lid or simply twisting it based on the design. Also, if you bought windshield washer fluid in a 1 Liter or gallon container, then you might want to decant it into a smaller receptacle that’ll make it easier for you to pour it without spilling.

Washer fluid reservoirs with large openings are usually easy to work with because you can just open it and pour the liquid with no problem. If yours has a small opening, try to find a clean plastic funnel that you can use to help pour the liquid into the reservoir.

The good news is that most reservoirs come with a clearly marked fill line so there’s no chance for you to overfill it. Plus, going over this line will compromise the effectiveness of the pumping system for your washer fluid. Once you’ve finished filling up the reservoir, you may replace the cap and make sure it’s screwed back on securely. If you spilled any of the fluid while decanting, now would be a good time to wipe it off.

Maintaining Your Windshield Wipers

Taking care of your car’s wipers is a critical aspect of maintaining your windshield. After all, what would your driving experience be like without windshield wipers? They add an element of safety and security that you cannot overlook. You simply cannot drive without them when it’s raining or snowing.

However, windshield wipers tend to sustain damage over time due to everyday wear and tear, but this doesn’t mean that you have to replace them.

After all, windshield wipers are pretty easy to understand. They’re made of several components that include an arm with a metal blade that moves from one side to another with a motor, and rubber material to make sure that they don’t damage your windshield.

How Long Does the Washer Fluid Last?

There’s no one size fits all answer to this question because it will depend on individual consumption and driving conditions. For instance, if you frequently drive in dusty gravel roads, your windshield will experience quite a bit of dust exposure, but that doesn’t mean you’ll have to add washer fluid regularly because you can just wipe the dust away with a clean cloth.

But, if you live in an area with frequent snow or rainfall then you’ll be using up a lot of washer fluid to remove both from your windshield.

Exposure to bugs that stick onto your car’s windshield will also require a fair amount of washer fluid to remove, which means you’ll need to use a variety that comes with an anti-bug formula.

Hazards That the Windshield Washer Fluid Will Protect You From

Ice is undoubtedly at the top of our list of the most hazardous elements from which to protect your car’s windshield. Left untreated, ice can lead to long-term windshield damage as your car will develop microscopic cracks that can develop into a real problem if your car goes through a mechanical issue.

It’s not recommended to use regular ice removal methods like scrapers because they could cause more harm than good. Rather treat your windshield regularly with washer fluid as a preventative measure against ice build-up when it snows.

The rest of the hazards are cosmetic in nature and don’t pose much of a threat to the safety and performance of your windshield. This includes things like dead bugs which you can easily remove using non-invasive and gentle methods.

Best Windshield Washer Fluids

Most people don’t realize this, but the type of windshield washer fluid you buy can make or break your car’s performance when driving in snow and rain conditions. It can also contribute to the overall health and lifespan of your windshield and it’s definitely an investment worth making if you care about your car.

Luckily, windshield washer fluid is fairly accessible and most brands offer formulas with anti-freeze and anti-bug properties, which is very helpful.

Now that you know what to look for when shopping for the best windshield washer fluids, here’s a list of our top options.

1 – Prestone AS658 Deluxe 3-in-1 Windshield Washer Fluid Review

Prestone is an award-winning and renowned vehicle fluid manufacturer, so you can be sure that anything they sell is top quality. This windshield washer is suitable to use all year round and it comes highly recommended for use during the winter time.

When used undiluted, this formula is exceptionally strong and can work in temperatures as low as -27°F (-33°C). That way, the formula doesn’t freeze in the washer’s jet hoses and it’s safe to use on any vehicle’s wiper blades.

Not only that, but Prestone’s 3-in-1 formula also offers rain beading technology that makes it easier for a vehicle’s wipers to remove rain droplets from the car while driving. Of course, it won’t work as well as a dedicated rain beading product but you’ll be glad to have it for those few minutes after you’ve spritzed it onto the windshield.

This washer fluid doubles as a bug and grime cleaner and some say it’s very effective at removing bugs and grime from a windshield window, even when the weather’s hot and dry.

You’ll also find that it’s exceptional at getting rid of ice and frost on those chilly days. You’ll definitely appreciate it if your car doesn’t come with heated washer jets. To get started with using this formula, simply mix equal parts of it with water in a spray bottle and spritz as much of it as you need onto frozen windows and even door handles.

Pros

Works as a de-icer and removes frost
Doesn’t come with the risk of freezing
Safe for all types of wipers

Cons

It doesn’t work as advertised when it comes to removing bugs and grime
Doesn’t last very long because it’s not concentrated

2 – P21S 11250F Booster Measure Bottle Review

As the name implies, the P21S 11250F Booster is not a washer fluid actually, but rather a product that’s designed to enhance the effectiveness of existing windshield washer fluid.

This is a great product to buy for anyone that’s shopping on a budget because then you can buy an affordable washer fluid and mix it with this stuff to maximize results. You may even combine the P21S 11250F Booster with clean water and get pretty much the same effect you would from a good quality windshield washer fluid.

Experts recommend mixing this booster with distilled water instead of normal water. That’s because distilled water doesn’t have any mineral deposits that will block the washer system of your vehicle.

At the topmost part of the P21S 11250F Booster bottle is a measuring compartment that tells you how much of the liquid you’ve used up. For the best results, it’s recommended to add two shots of this formula to two gallons of washer fluid.

It will keep your windshield free of oily films so that it’s clear enough for you to drive comfortably at night, and you can easily add anti-freeze liquid to it for use in winter.

Pros

Helps to get rid of oily deposits
Reduces glare from the windshield, which makes it safer to drive at night
Can be added to existing washer fluid or distilled water

Cons

It’s not formulated to protect your car’s windshield in freezing weather conditions

3 – Rain-X White RX11806D Washer Fluid Review

This product is the best car windshield cleaner to get if you’re prone to getting dead bugs and rainwater on your windshield. Once it has been applied, the Rain-X White RX11806D formula leaves a thin protective film on your windshield, which makes it more resilient to dirt, dust, and bugs. Also, it turns rainwater into tiny manageable beads that your wipers can easily take care of.

Like the previously mentioned product, you may add it to existing washer fluid if you have a cheap brand, or combine it with distilled water.

It’s worth noting here that it doesn’t perform well in freezing temperatures, but if you add it to the Prestone De-Icer, for example, then it can work for all weather conditions. The best part about this product is that it’s malleable, which means you may alter the mixture if you like to create a more concentrated solution depending on the amount of water in it.

All in all, the Rain-X White RX11806D serves as a protective layer over your windshield that offers beading technology.

Pros

Can be added to washer fluid
Creates a protective layer that keeps dust, dirt and bugs away
Comes with exceptional water beading technology

Cons

It’s not very effective in low or freezing temperatures
Doesn’t work as well as applying a dedicated beading product

4 – Prestone AS657 Bug Wash Windshield Washer Fluid Review

The Prestone AS657 Bug Wash is ideal for use in the summer or otherwise warm and humid weather conditions. It’s very effective at removing and protecting your car’s windshield from dust, dirt, grime, grease, and bugs.

As such, this windshield washer works really well for people who like to take summer road trips; because you never know what type of bugs you might come across on the road.

Unlike most windshield washer fluid products that will only get rid of bugs after they are stuck onto your windshield, the Prestone AS657 offers a preventative method that will help to reduce or eliminate the possibility of bugs getting stuck on the windshield. All you have to do is treat your car with it right before your journey and you’re all set!

It might also be a good idea to start the treatment with a coat of glass polish such as the Griot’s Garage Glass Polish, followed by a liberal coating of Prestone AS657 Bug Wash. Your windscreen should be dry within 10 minutes of application, but you’ll want to polish it in beforehand so that it dries out nicely without any streaks.

Although wonderful for use in the summer, this washer fluid is not effective in cold weather at all because it doesn’t have anti-freeze properties.

Pros

Gets rid of traffic grease and grime
Protects the car windshield from bugs and dirt
Doesn’t cause glare
It won’t leave your windshield with streaks

Cons

Doesn’t come with anti-freeze
Doesn’t offer a beading finish for when it’s raining

5 – Nextzett 92100815 Kristall Klar Washer Fluid Review

The Nextzett 92100815 Kristall Klar is arguably the most concentrated windshield washer fluid on the market. In fact, it’s 200x more concentrated than its closest competitor and an 8.5oz bottle of this product can refill 6 to 8 regular windshield washer fluid bottles.

However, unlike other highly concentrated washers, the Kristall Klar fluid comes with water softeners to prevent clogging in your jets, pumps, and hoses. It’s very effective at removing residues that might plague you whilst driving, and most reviewers have likened its efficacy to that of OEM washer fluid which is what you get when you purchase a new German vehicle.

The best part about this windshield washer fluid is that it won’t leave white residue on your windshield which is quite common with cheaper washer fluids.

The only downside to it is that it’s not suitable for freezing or otherwise cold weather conditions. It cannot work in temperatures below -76o F.

But since it doesn’t contain any ammonia or methanol, it’s good for the environment and worth considering for the eco-conscious customer. Plus, it’ll leave your car windshield with a lovely citrus scent.

Pros

One of the best windshield washer fluids on the market
It won’t leave white residue behind
Eco-friendly
Doesn’t come with the risk of clogging your vehicle’s washer system up

8 – 303 Products (230371) Instant Windshield Washer Review

303 Products’ Instant Windshield Washer is a simple and straightforward product. It does a very basic job at removing stains, dirt, grime and bugs from your windows, but don’t expect it to perform miracles.

For instance, it doesn’t offer an anti-smear finish which means you might have to put your back into it when wiping it on. But, it’s on the list of the best windshield cleaners which means it’s a good product.

Sure enough, this windshield washer offers great value for money, as each pack comes with 25 tablets at $10 overall. Each tablet gives you 1 gallon of washer fluid when dissolved in the same amount of water. And you don’t have to use special water either, because it works just fine with tap water.

All in all, this is a great budget option that can still get you the desired results.

Pros

Budget-friendly

If you’re looking for the best windshield wiper fluid on a budget, this is it. The Sonax Clear View windshield washer concentrate comes with a refreshing lime fragrance and it works on glass and plastic alike.

It’s effective at getting rid of oil, grime, dirt, insects, films, and silicone for a streak-free finish. You may even use it to clean your headlights. It’s phosphate-free and since it has an anti-lime effect, you can safely mix it with tap water. But be careful not to mix it with “hard” water as that could lead to clogging on your vehicle’s nozzles. In such cases, it’s recommended to swap hard tap water with mineral or filtered water instead.
