Features to Look For When Shopping For Best Windshield Washer Fluid

Knowing what you’re buying is essential to be sure that you are getting your money’s worth when purchasing a windshield washer fluid. Here are the most important features of this kind of product to speed up your purchasing process and help you make the best decision possible.

  • Water-repelling – The product you choose won’t actually repel the water, it is the windshield we are speaking about here. Still, there are some washer fluids that are designed to encourage water to bead on the windshield’s surface of your vehicle. What this feature essentially does is keep the water from the rain in big drops that run easily off the surface of your car. This makes your wipers work more effectively and as a result, improves your vision and safety on the road. If you live in a rainy area, water-repelling is a feature that is a must.
  • Dilution – It is time to talk more about the matter of value and storage. You should be aware that some windshield washer liquids are quite powerful and are to be diluted with water before you add it to the washer reservoir. You can count on getting better value with products that require dilution. However, the type of washer liquids that don’t need it is relatively easier to use.
  • Smell – Some windshield washer fluids have a scent, usually a citrus-based one. You won’t be able to smell it much inside the car, but if you want your windshield to smell of citrus, then choose a scented washer fluid.
  • Streak-free Finish – Just like with cleaning your windows at home, it is all about that finish. Streaks on the windshield are ruining your car esthetics and damage the clear visibility you are looking for after a wash. The best products for windshield cleaning do not leave any streaks behind.
  • Antifreeze Technology – This is one of the most important features if you live in an area where you get a lot of colder months. If you do live in such a place, make sure to double-check whether the windshield washer fluid of your choosing has a built-in antifreeze. The diluted products will most probably have less antifreeze tech inside them, but you can always add in some 90% proof alcohol, that you can find in a hardware store, and improve the antifreeze factor of your product.

Benefits of Using a Windshield Washer

We move on to the benefits of using a windshield washer fluid, and it is not only a clean glass. There are actually more advantages of using such a product, and knowing them might convince you always to trust a quality product. Here are the benefits of using a windshield washer.

  • Improved safety – Please note that the majority of accidents related to using a car happen during rainy days. A quality car window washing
    fluid will increase the level of safety on the road in the rain. Safety is always a priority, so purchase a windshield washer that has the water-repelling feature.
  • Ease of use – A windshield washer is one of the most straightforward vehicle care products to use. Taking advantage of the fact that in this case, little effort means massive outcomes is a pleasure.
  • Better detailing – If you are a real car lover and you put a lot of effort into making your vehicle look good, you might want to make your car shine even more by making sure your windshield is clean at all times.
  • Healthy windshield – When it comes to cars, you always strive for longevity. When you take good care of your windshield, there is an increased possibility of you spotting chips earlier and having them repaired before they turn into a bigger problem.

Different Types of Windshield Washer

Before you enter a shop with the intention to buy yourself the best windshield washer fluid available on the market, you should know that, in general, there are two types of a window washer. They are the window cleaner and washer fluid, understanding the difference between the two should help you make the best decision for your car’s windshield. Let’s explain what these two types of vehicle care products are all about.

Cleaners – They act more like detailing products. You apply them directly to your windshield with a fabric or a microfiber towel. Then, you clean the glass carefully, and in the process, you leave a protective layer on the glass, ideally to aid water beading.

Washer Fluids – They are most commonly associated with a windshield washer. The product goes inside the reservoir tank under the hood, and you spray it onto your car’s windshield typically when driving. You use mostly for cleaning purposes, so you want the fluid to feature a strong cleaning power, as the number one feature.

At the end of the day, you will most probably use the mixture of the two types of cleaning products. Use a cleaner when you are cleaning and detailing the car to make your windshield look perfect and well taken care of. Then, go for the right washer fluid when you’re behind the wheel and keep your visibility at an all-time high.

Reasons Why Car Windshield Cracks

Keeping your windshield clean is one of the ways in which you can monitor its health. When we talk about the health of your windshield, we have in mind a glass without any cracks. Because cracks in the windshield are dangerous, you should know why they crack in the first place in order to minimize the risk. There is a range of reasons why glass breaks. The best way to learn about them is via a specialist who makes them. This is why we asked a windshield producer about the possibilities of our windshield cracking.

Poor installation – the factory-installed windshields usually are installed under high safety and construction standards, but it may occur that a windshield is not installed as precisely as it should. If it is installed poorly, the windscreen can be loose and cause some vibrations that can result in cracks.

Temperature changes – severe changes in the temperature can cause the glass to expand and shrink rapidly, especially if there is a defroster and car heater involved. Because the glass is typically heating up much faster around the edges, the expansion and contraction that is happening can contribute to the glass cracking.

Sunlight – sunlight can cause similar problems as the temperature. The heat coming from the sun can cause the edges to expand and contract faster, and the glass is cracking in the process. This is why keeping your car in a place with a lot of shade is recommended.

Pressure changes – it’s not about the barometric changes, but sudden pressure changes that can happen when shifting from low to high speeds. Please note that wind gusts and heavy objects resting on the glass can be the reason for stress cracks.

Hail – hail storms with massive hailstones can also damage your windshield. The ball of ice hitting your glass at high speed is the same as striking it, sometimes it will result in a crack, depending on the size and power of the hailstone.

Glass imperfections – in rare cases, glass that is installed to your vehicle might be defective. You may not realize it, but an auto glass shop worker will. Defects involving glass are rare, but they can also be the reason for your windshield cracking at one point.

Best Windshield Washer FAQ

Finally, let’s answer the frequently asked questions surrounding the topic of best windshield washer fluids, and make you the specialist in this regard. Here are all your questions answered.

➡️ How do windshield washers work?

The windshield washers provide an additional element to the cleaning power to let your car tackle the dust and other forms of dirt that can build up on the surface of the windshield. In addition, many higher quality washer fluids offer some additional cleaning features, like water repelling, for example.

These kinds of products can also be designed as antifreeze substances and be helpful in removing ice build up. They form a protective barrier which makes the water bead and sprays off faster, which result in a better vision while you are driving in the rain. You can even go for a citrus scent with washer products if you like your windshield to have a fruity smell.

➡️ Why is water not enough to clean a windshield?

Water doesn’t have any additional washing features, as mentioned above. It is unable to handle more challenging forms of dirt, like serious grime, bugging splatter or tree sap. In those cases, the water actually can do more damage than good, as it can smear the grime all over the windshield. Untreated water also has a relatively low freeze point. Using only water doesn’t protect you enough and makes it impossible to ensure visibility at all times.

➡️ What is inside the windshield washer fluid?

You should know that each producer or manufacturer uses different ingredients to make their products, and each product has its own unique recipe and specific ratios of ingredients used. The washer fluid itself will most likely contain methanol or ethanol (to act as an antifreeze ingredient to a certain extent) and other components that depend on the additional features a manufacturer wants to introduce.
If you are concerned about some of the ingredients that could be used in the producing process, please remember that the packaging of the product has to include a full list of ingredients or at least highlight the hazardous materials and their quantities. Reading the label before you purchase any kind of cleaning detergent is always the right way to go.

➡️ How to add a windshield washer fluid to a car?

The right course of action when it comes to adding any fluids to your vehicle is to check out the car manufacturer instructions. However, broadly speaking, it is a relatively simple activity to perform. All you have to do is find the washer reservoir, open its lid and fill it up. Do not go beyond the marked Maximum Filled Line, if you don’t see such a line then refer to the instructions to know the maximum capacity of your washer reservoir.

➡️ What is the right course of action when the windshield washer fluid is frozen?

You might find yourself in a situation when you press the spray button, and nothing happens, if you think that your washer fluid is frozen, do not repeat that action, as it may damage the whole mechanism. Remember that fluids expand once frozen, so you need to check immediately for leaks once it has thawed, and take care and repair the pipes and the reservoir tank itself before you use it again. In the future, please think about purchasing a windshield washer fluid that has some antifreeze qualities to it, or buy a bottle of 90% alcohol from your local hardware store and mix it into the washer fluid that you already have to raise its freezing point.
