When it comes to driving safely and responsibly, it is imperative that you keep your windshield clean (especially if you are traveling in extreme weather). A dirty windshield or one that is hazed in the winters can drastically hinder your visibility, be it morning, afternoon, evening, or nighttime. You need to be able to see with the uttermost clarity on the road to ensure you don’t end up trashing your car or injuring yourself.

This means you must always try your best to keep the windshield clean and free from obstructions, as standard as checking your mirrors and putting on your seat belt. After all, there a reason the police stops you if your windscreen is sufficiently sullied to hinder your vision and view of the road. Yes, cleaning your windscreen regularly is quite the task, but this is where effective wiper fluid or screen wash fluids come in handy.

What Are Windshield Washer Fluids?

What Are Windshield Washer Fluids?

As the name implies, windshield washer fluids are used for the cleaning of your windscreen. The fluid is typically poured into the reservoir, which is located under the hood of every car. Once topped up, you can use the vehicle controls for spraying the fluid out on the windscreen. You can then activate the windscreen wipers to clean out the dirt, debris, and haze while driving.

These washer fluids can give your windshield a clear and clean look even in the worst weather. However, depending on where you live, you may require a different fluid product. For instance, for those living in areas of extreme snow, it is a good option to opt for windshield washer fluids that have antifreeze compounds like methanol.

These washer fluids for your windshields are available in three forms: a liquid that is pre-mixed and ready for use instantly, an additive that has to be mixed in water, or tablet forms (or crystals) that have to be dissolved in distilled water. The products that have to be dissolved have different dilution ratios, depending on the climate/weather the area you live in experiences.

Regardless of the surroundings, quality windshield washers give drivers the capability of preventing their windscreens from becoming dirty. Since you can easily spray the fluid while driving and use the wipers for cleaning, you can feel assured to clean the windshields lesser, as you would normally do in most adverse weather conditions like heavy rainfall and snow.

Qualities Of The Best Windshield Washer Fluids

Qualities Of The Best Windshield Washer Fluids

Bug Repellent

The best windshield washer fluids must feature bug repellent adhesives and compounds that ensure your windscreen does not attract any kind of weird bugs. Typically, when driving in some areas bugs may splatter on your windshield. Getting rid of them can result in a rather sticky mess. Windscreen washers with bug repellent compounds can create a surface that prevents bugs from sticking.

Water Repellent

In areas of heavy rainfall, it can become quite a difficult task to drive a car – as you can’t see the road at all. This can also be extremely dangerous and result in major accidents. To avoid this from happening, your windshield fluid should contain the necessary water repellent compounds for preventing water from pooling on the windshield and distorting your vision. The fluid should cause the rain to bead up and roll off instantaneously.

Concentrated Formula

For the best cleaning results, it is advised to go for windshield washer fluids with a concentrated formula. These products have concentrated varieties of compounds present, ensuring that you only require a small quantity of the liquid to be mixed in water. This guarantees savings while preventing your windshield from getting dirty.

Antifreeze Compounds

Some all-rounder windshield washer fluids feature antifreeze compounds for preventing water or snow from freezing on your windscreen. If you live in an area that experiences heavy snowfall or temperatures that freeze water, go for windshield washer fluids that come with antifreeze to melt the ice well and restore complete visibility on the road to prevent any sort of accident or mishap.

Pre-Purchase Considerations


If you plan to buy a windshield washer fluid, here are a few considerations you should keep in mind:

  • If you are buying a crystal or concentrated windscreen washer fluid, it is imperative that you follow the instructions about the dilution ratio properly based on the weather and climate of where you are living. Otherwise, the washer may end up getting too sticky to remove or might result in excess, an unwanted haze that can hinder your visibility.
  • Windscreen washer fluids that have methanol present in the formula can have quite an irritating smell that not many can tolerate. If you experience irritation from the smell of methanol, it is a good option to opt for ethanol-based washer fluids. Ethanol is a light form of methanol that doesn’t produce a bad smell.
  • ​While buying ethanol-based formulas, check if the product you are buying has ethylene glycol (EG). This compound is essential for the efficient mixing of products that have to be distilled with water. EG also has a polishing formula that proves incredibly useful in cleaning your windshield in windy weather in which dirt, debris, and bug splatter may be stuck on your windscreen.
  • ​If you are living in not so frigid areas where the weather doesn’t hit freezing temperatures, opt for washer liquids that have low methanol content. While methanol proves to be a highly effective antifreeze component, it is very toxic. At the same time, can also heat up quickly under extreme heat.
  • There are plenty of different types of fluids available in the marketplaces that are formulated for the climate you are living in. However, if you find the dilution ratios and mixing highly complicated, you may want to opt for “all-season” products, which can maintain its liquid form in hot and cool weather. For extreme weather, these products can be mixed with antifreeze compounds to ensure your wipers work efficiently in heavy snowfall.
