Windshield Washer Fluid Buying Guide

Looking for the perfect windshield washer fluid, but don’t know where to start? After all, there are hundreds of different products out there, all offering the best features and performance, but not all staying true to their promise.

Don’t you worry. I’m here to help you out. Here is a complete guide of all the important things to look for when buying a windshield washer fluid so you can find the most helpful product that works perfectly for your needs.

What is a windshield washer fluid?

First things first- let’s talk about exactly what a windshield washer fluid is, and how it works.

As the term suggests, a windshield washer fluid is a chemical formulation that serves the purpose of cleaning your windshield, so you get clear visibility at all times while you’re on the road.

With a windshield washer, you won’t have to worry about things like dirt, grime, and grease buildup, as well as animal and plant droppings and fluids leaving a sticky residue on your windshield, all of which reduce your visibility and even cause glare when you drive at night.

Windshield washer fluid vs water and windshield wipers

But, why can’t you just use water? Maybe even some soap to clean your windshield? Or why not just turn on your wipers to wipe down these substances?

Well, when it comes to wipers, these are primarily designed to try and wipe away rainwater so they don’t bead on the windshield and blur your vision. As for other substances, oftentimes windshield wipers just make things worse by spreading around these icky and dirty things.

And as for water and soap, water is often not enough to remove stubborn dirt and sticky fluids, and soap almost always leaves streaks that can cause glare and generally just look unpleasant. Plus, windshield washer fluids are the only ones that come with various added features to keep your windshield clean and free from debris for longer.

Type of windshield washer fluid

Type of windshield washer fluidNow, one of the first things you need to decide on is what type of windshield washer fluid you want to use for your car. Below are the four different types of windshield washers and how they differ from one another:


As you can probably guess from the term, concentrates are concentrated liquid solutions that need to be diluted in order to have a usable mixture of washer fluid.

These are cost effective and long lasting solutions, since just a few droplets can be used to clean your entire windshield already, so a full bottle will last you for a long time.

Stand alone product

On the other hand, if you don’t want to deal with the hassle of mixing your own solution and risk incorrectly measuring the required ratio of water and washer fluid, then you might want to opt with stand alone washers, which are already pre-mixed and ready to use right out of the bottle.

The only catch is, they are generally more expensive, especially considering they are already diluted with water or other solutions.


There is also the additive type, which is quite literally just that- an additive. You add this to whatever generic windshield washer fluid you already have in order to increase its cleaning and protection properties without having to buy a new solution altogether.

Common capabilities and features of additives include more quickly dissolving dirt and grime, completely washing off bug splatter, or adding water beading properties to the washer fluid.


Finally, you’ve also got tablets, which are the most convenient and portable windshield washers, since they come in small candy sized packages that you just dissolve in water to clean your entire windshield any time you like.

So, if you want to be able to clean your windshield on the go, especially if you’re planning on taking long road trips, going camping, or driving somewhere you might encounter adverse weather conditions or lots of insects, then tablets are a good idea.

Container size

In relation to portability, the size of the product you’re buying should also be factored in. For one thing, you definitely wouldn’t want something that will only last you a few washes.

But, you might also not want something that’s too big that the only realistic place you can keep it is in your garage- although you can always just pour a bit of the solution in a smaller container to take with you on the go.

Let me be honest with you- size doesn’t always matter. It really has to do with how concentrated the product is. For example, if it’s ultra concentrated, you might be able to get a year’s worth of washes from a small bottle, as compared with a gallon of diluted solution.

Residue and streak free

The most important thing when it comes to any cleaning product, especially those that are made for windshields, is that they don’t leave any residue or streaks, so that your road visibility doesn’t get negatively impacted, or worse, be the cause of accidents on the road.

It’s not like other products for your car exterior that you want to be streak free for appearance purposes. When it comes to your windshield, streak and residue free is the key to safety.

You’d also want it to stay that way for a long time, so it’s wise to look for a washer fluid that has water beading and bug repelling properties. For these things, alcohol based fluids and additives may be your best bet.


Where do you live, and where do you often drive? What’s the usual weather condition there? These are also important questions to answer, because these will determine the necessary properties that your windshield washer fluid should have.

For example, in more tropical areas with hotter temperatures, you might have to deal with a lot of bugs, insects, birds, and even plant saps, so you’d want some form of protective barrier. Or if you live somewhere that gets a lot of rain, then you need water beading capabilities.

Meanwhile, those in the colder parts of the world or those needing to clean their windshields during the winter will need antifreeze properties for their windshield washer fluids.

It’s crystal clear that windshield washer fluids are an important cleaning solution that all car owners should have in order to keep their windshields, well, crystal clear. Aside from cleaning your windshield, a washer fluid also offers lots of different capabilities that will keep your windshield in peak condition for longer.

When it comes to the question of which is the best windshield washer fluid, the answer really depends on your requirements and personal preferences, but I highly recommend the Prestone AS657 Bug Wash Windshield Washer Fluid.

It’s a handy and easy to use pre-mixed solution that works great in cleaning your windshield, offering protection against bugs and saps, and adds water beading properties to your windshield, making it the perfect and easiest to use product during the summer season.
