Windshield Washer Fluid Buying Guide

Choosing the best windshield washer fluid is not the most complicated task, related to your car’s maintenance. However, that does not also mean that it will never be confusing, considering the products available on the market. So, this section of the article will help you in choosing the best option, narrowing down the choices so as to arrive at the most suitable product for your needs.

Popular Methods

There are two popular methods of using a windshield washer fluid. Below is a brief enumeration of the methods with their corresponding descriptions that are never confusing at all.

  • Diluted Mixture – When shopping for such items online, you will instantly notice the differences between the products. The first method you will encounter is the diluted mixture, which is prepackaged, and comes in a jug or gallon most of the times. These diluted mixtures have been pre-mixed by the provider, giving you an on-the-go washer fluid that you can use immediately upon purchase. This method eliminates the daunting tasks of measuring, diluting, and so on.
  • Concentrated Tablet/Liquid – On the other hand, this method is more prevalent, based on the reviewed products above. Buying concentrated liquid or tablet requires dilution process, following the water and product ratio that is suggested by the manufacturer. Most of these products allow you to make gallons of diluted mixtures for a good supply over a period.

Important Tips to Consider

As the experts suggest, here are some of the most important things that you should consider when buying windshield washer fluid tablets or fluids. Included in this section are more pointers you should keep in mind throughout the maintenance of your car.

Never Use Water Alone

Among the common mistakes done by car owners is the use of plain water. Surely, making use of water alone can get your windshield clean, although the effects are limited during warm weather. When the temperature drops, the water in the reservoir tends to freeze instantly, affecting the lines as well. This scenario results in unwanted damages to your tank and washer system; thereby, causing an inefficient driving all throughout, blinding your way and may cause further accidents.

Another thing to consider is the potential of microorganisms, such as bacteria that could grow in your reservoir. Remember that even the purest or most distilled water can cause microbes, especially during the hot season. In most cases, the Legionella bacteria make their way in reservoirs, which causes the Legionnaire’s disease. Therefore, it is advised to use water alone; instead, relying on fluids or tablets, especially meant for such purpose is the best thing to do.

Climate Effects

It has been mentioned about the bacteria caused by water alone, especially during hot climates. So, when it comes to cold seasons, the fluid in your reservoir also has the tendency to freeze up. You’d want to ensure that this will never happen. Those living in harsh winter climates should consider a windshield washer additive that contains antifreeze due to such temperature.

Most manufacturers provide details regarding the temperatures that their products can be used safely. You can easily read them on the bottle labels. Otherwise, you can ask the provider about such information, whether it is good for winter or an all-season formula, and so on. Take note that some products may require you to dilute or thin the fluid with water, while other products come as pre-mixed for your specific climate. Surely, there are different types and brands on the market, so, reading the label is a must.

Significance of Concentrate Fluids

The best thing about the concentrated fluids is that they allow you to make your own cleaning solution with the exact amount that you need, instead of keeping a big jug of pre-mixed product in your trunk. The best windshield washer fluid or tablet has the maximum potential of cleaning your windshield glass, while eliminating potential bacteria at the same time.

But then again, you must ensure that you’re getting the appropriate product for your specific climate. Moreover, the concentrated fluids and tablets are more preferred by car enthusiasts due to their convenience and efficiency that never fail the washer system, unlike the pre-mixed counterparts.

Wiper Blades

Considering the function of your wiper blades is equally as important as your entire washer system. If your blades seem to be making a mess with the windshield, perhaps, it is time to replace them. You can also opt for new inserts such as rubber wiper inserts that you can easily slide into place, although they may cost you substantially. Metal blades, on the other hand, may be more affordable over the rubber.

It is also wise to refer to an auto parts store or your owner’s manual for the best blade type and size. Bear in mind that the wiper sizes also differ, considering the driver and the passenger side that requires varied blade sizes. Check out your rear window as well if it’s still in good condition. By considering your wiper blades, you can maximize the cleaning power of a windshield washer additive.

Special Benefits

Due to the intense competition of such consumer products, some manufacturers also offer added benefits. For one, manufacturers offer their products by the pack, giving you a discount for such bulk purchase. You can certainly enjoy a huge discount rather than buying a single bottle or jug one at a time.

Other manufacturers offer extra benefits that come with the performance of their products such as an added dirt-removing strength or the beading technology of the RainX washer fluid additive, which repels snow, sleet, and rain.


All in all, adding windshield washer additive is a very straightforward task, and is an essential part of the overall maintenance of your car. Making use of the best product and its regular use will not only help in the maintenance of your vehicle, but also provides you with clear road visibility for safe driving at all times.
