Best Windshield Wiper Fluid for Winter and Summer [2021 Review]

It seems that windshield are in need of constant cleaning. Our cars go everywhere, and quickly too! Our windshields see a lot. Squashed bugs, crusty, dried bird poop, dirt and gravel are annoying and dangerous when they are plastered all over your windshield. They obstruct your view and can be downright damaging to your car, aesthetically and long-term if left to bake in the sun long enough. If you live in areas that receive snowfall, I’m sure you know all about the hazy film salt from the roads can leave on your windshield. Winter is the enemy.

What is the one thing that can sometimes make plastered bugs worse on the windshield? Using those windshield wipers with some crappy windshield wiper fluid! (Is that just water?) It smears the gunk all over, seriously impacting your vision at that point and you are left with a streaky, sticky mess that is impossible to see through.

In this article, I want to cover a number of different products I have tested and provide insight about the best windshield wiper fluid for the winter, summer and other times of the year.

More often than not, you are forced to use the gas station squeegee just because your wipers just are not cutting it. It is time to minimize the frustration and time you spend cleaning your windshield because we have vetted out the best windshield wiper fluid for you.

Choosing the best windshield wiper fluid is an essential part of maintaining your vehicle. To ensure you get the best bang for your buck for a quality and affordable fluid, here’s a look at some of the top-rated brands. 

Top Windshield Wiper Fluids


Depending on your car, location and needs, choosing a wiper fluid that best suits you can be tricky. It is important to use actual windshield wiper fluid in your car because water will not cut it! It is NEVER a good idea to use water. Water runs the risk of calcium deposits and poor cleaning performance. In cold climates, water will freeze and potentially damage the pump, lines and reservoir. In warm climates, plain water can build bacteria and mold.
Changing or adding windshield wiper fluid is simple. You can consult your owner’s manual to help you locate the location of the washer fluid reservoir. As long as there are not any specific instructions in the manual as to how to go about adding the fluid, it is simple. To add the fluid, you just pop the hood of your car, locate and open the windshield washer fluid cap (there will be a windshield washer symbol on it), pour in the fluid while using a funnel (only fill up to the fill line), and then close the cap. Using a funnel can be very helpful to avoid making a mess. Some of these windshield wiper fluids can stain clothes, so be careful.

1. Aqua charge Windshield Washer Ultra Concentrate

We are all about the biggest bang for your buck. This product produces 55 gallons of fluid because it is highly concentrated. Because you mix the fluid with water each time, the $20 price tag ends up being a few cents per gallon. After vetting reviews, it seems consumers were very pleased with the results, but the feedback warns that it is extremely important to use the correct amount when mixing the product with water for optimal performance.

PROS

  • 55 gallons worth of fluid
  • No residue

Buying Guide

Performance is paramount when trying to find the windshield wiper fluid that best suits you, your vehicle and your needs. If you are reading this and have made it this far, there are a few features you are seeking out the most. Maybe you do a ton of highway driving and constantly have bugs plastered to your windshield and they get smeared by your wipers and baked in the sun? Maybe you live in the cold and winters are miserable with freezing temperatures and frost and ice? Maybe you’ve had enough with smearing, streaking and smudging? Here are a few things you need to consider before clicking add to cart and purchasing your new windshield wiper fluid.

Bug Prevention

First, how often are bugs on your windshield a problem for you? This is vital. Bugs are not only annoying and damaging to your vehicle after time, but they create visibility issues as well. Safety is priority. If pesky bugs are your main concern, you may want to opt for Prestone Bug Wash Windshield Washer Fluid for the bug barrier mechanism. Prestone’s 3-in-1 and Rain-X’s 2-in-1 formula also may be a good option as they offer bug-repellent as well.
Note: If you are just now switching over to a bug-friendly windshield wiper fluid and currently have a nasty buildup of bugs on your windshield, vinegar is said to be very helpful in removing the bugs and grime from your glass. Just be sure to NEVER put vinegar in the windshield wiper reservoir as it can damage it.

Ice and Frost Prevention

Do you practically live in the tundra and constantly fight a frozen windshield? To protect your car and windshield from damages and for your convenience, looking into a windshield wiper fluid that fights ice and frost in extreme temperatures is vital. If your windshield wiper fluid does freeze, this could damage the pump, lines and reservoir because of the expansion of the water, all costly and dangerous.
On a side note, if your windshield wiper fluid does happen to freeze, never use hot water to try and thaw it out. The hot water mixed with the cold water can actually crack and break your glass window.
If you need to invest in a winter-friendly windshield wiper fluid, either Prestone’s 3-in-1 or Rain-X’s 2-in1 is a superb option as they both offer other features as well. However, Prestone’s De-Icer windshield wiper fluid is specifically focused on battling winter’s nasty effects on your washer fluid and can leave you confident that it will not freeze. Also, do not forget that some of the other products discussed also have de-icer or have the option to add methanol for an anti-freeze feature.Prestone’s De-Icer Aerosol is a great extra product to keep in your car for extreme situations. With this can, you spray it on your windshield and use the built-in scraper to remove snow, ice or frost from your windshield.

Water Repelling

Do you experience a lot of rainfall on the road? The amazing water beading feature of Rain-X and similar products are almost luxurious. Sometimes, in a light drizzle, using your wipers is not even necessary as the water glides off of your windshield so nicely. This feature makes a dramatic difference in rainy driving conditions and visibility. In a downpour, water repellent truly helps get that water out of your way faster. If this is the main feature you are seeking, take a second look at Prestone’s 3-in-1 formula or Rain-X’s 2-in-1 formula.


Keep in mind that Rain-X additive can be added to any washer fluid to enhance the performance.

Concentrated and Cost-Effective

The concentrated windshield wiper fluid we mentioned are all great options with some differences amongst them. What is great about purchasing a concentrated option is that they can be mixed with water to produce gallons and gallons of windshield washer fluid, saving you plenty of cash in the long run. Some of the concentrated options, such as Aquacharge Windshield Washer Ultra Concentrate require additives for non-freezing features but are great options for non-streaking. Flo Tech’s concentrated product can yield up to 100 gallons of windshield wiper fluid and is even biodegradable. Sonax Clean View Windshield Washer is great for use on all types of glass, even XENON headlights.
So, take some time to sort through the differences listed in each concentrated option provided.

Health and Environment Concerns

So, we learned earlier that in warmer climates, using plain water can breed bacteria, specifically Legionella bacterium, which causes Legionnaire’s’ Disease and pneumonia when you breathe it in off of the windshield. Sometimes, using only water can just create a terrible mold build up as well. However, using windshield wiper fluids doesn’t always have to be harshly toxic either. Products such as Flo Tech Windshield Wiper Fluid are biodegradable and non-chlorinated. Sonax Windshield Wiper Fluid is phosphate-free. Kristall Klar Windshield Wiper Fluid is ammonia-free. With these options, caring for your health and the environment is made a little easier.
Note: if you notice a strong chemical smell from any windshield wiper product, discontinue use and opt for a more environment and health friendly option.

Conclusion

When you are shopping for the best windshield wiper fluid, chances are that price is just as important to you as performance is. It seems that if you live in a warmer climate, a more general windshield wiper fluid is ideal for you. In colder climates, a more specific fluid is essential. Concentrated options offer a larger bang for your buck. You have a big decision to make.
Keep in mind that if your windshield wipers have been making an absolute mess of your windshield, despite a good windshield wiper fluid, it may be time for some newer or better wiper blades. Old or cheap wiper blades can be damaging and obstructive to your visibility.
Price is a big component in your decision. Remember that you truly do get what you pay for. More basic fluids may not perform as well as those specifically designed to meet a specific need. Paying a little extra for the best product will pay off in the long run.
With many options available, meeting your consumer needs for a clean windshield is easy. Safety is the main concern of any road trip!
