1. Standard  Windshield Washer Fluid

The  standard  windshield washer  fluid is a  blend of:

Water: Combines  with other chemicals  to dissolve the dirt  for easy cleaning

Isopropyl Rubbing Alcohol: Disinfects the windscreen surface without corroding the vehicle parts. Though to a small extent, the alcohol content also prevents the windshield from freezing.

Lubricants like glycerine: Reduce the friction, skipping, and shuddering of the wipers during their action on the windscreen surface to elongate their service life. They also dissolve the dirt  for effective cleaning

Hard water softeners: Prevent hard water mineral buildup that may otherwise clog the spray jets or corrode the windshield washer pump.

However, the formulas falling under this category contain little or zero anti-freezing agents (alcohol), meaning they might freeze if used in areas with cold weather extremes like Alaska, North Dakota, Maine, etc.

In addition, the formulas may come in different colors, including blue, green, orange, yellow, etc.,  depending on the manufacturer’s preferences.

The 92100815 Kristall Klar Washer Fluid by Nextzett is the perfect example of standard windshield fluid.

You can order the standard wiper fluid from any online store or buy it in your neighboring physical store for vehicle accessories.

The fluids may come as a concentrate,  requiring dilution, while others may come as ready fluids, offering more convenience. Be sure to check the instruction manual before applying to avoid mistakes.

Pros

  • Cleans most  types of  dirt
  • Avoids friction, and shuddering of the wipers on  the screen  surface,  to elongate their life
  • It doesn’t corrode or stain the vehicle parts
  • Affordable option 

Cons

  • Not ideal for cleaning during winter  due to lack of anti-freezing agents

2. Bug Remover Wiper Fluid

WINDSHLD WSHR BUG 1GL

As the name suggests,  the bug remover wiper fluids are specifically formulated for cleaning bug splatter, road grime, tree sap, bird droppings, and other types of dirt on the windscreen. They are ideal for use during the summer and spring seasons when birds and bugs are most prevalent in yards,  garages, and roads.

The common ingredients you can find in most bug remover wiper fluids include:

Power Cleaners like vinegar solution to penetrate and break down the hard residues, for hassle-free cleaning.

Bug Stoppers like isopropyl alcohol to create a non-stick surface (barrier) which prevents road grime, bug waste, and other unwanted elements from sticking on the windscreen.

Lubricating Agents to avoid friction and vibration  of the wipers on the windscreen to boost their durability

Essential Oils  to add  some fragrance to the windshield fluid

Coloring  Agents  attract and  allow vehicle owners to identify their favorite windshield fluids easily

Like standard wiper fluids, most bug wiper fluids don’t have anti-freezing agents, hence not ideal for areas with freezing temperatures.

The Preston’s Windshield Washer Bug and the SH HS 29.606 Bug Wash Windshield Washer Fluids are perfect examples of bug remover wiper fluids you can find on the market. 

Pros

  • Contain power cleaners that penetrate and  break any unwanted elements, including bug  splatter, tree sap, bird droppings, etc., on the windscreen
  • Contain stain-free agents to repel the sticky elements from attaching to the windscreen

Cons

  • They  lack anti-freezing agents

3. Water Beading Windshield Washer Fluids

Rain-X White RX11806D Washer Fluid Additive-16.9 fl. oz, 500. ml

These are silicone-based formulas that force water drops to bead up and roll off to the ground after hitting your windshield.  The idea behind the beading action is to help avoid the accumulation of rainwater on the windshield for clearer visibility.

As the vehicle accelerates, its speed and that of the wind compel the rainwater to go up the windshield, decreasing your visibility on the road. And, Water Beading wiper fluids come in handy to help you avoid such water buildup.

Examples  of ingredients you may find  in these  formulas include:

Ethanol acts as a  solvent in dissolving other ingredients. Ethanol also helps remove oil and other dirt from the windscreen.

Isopropanol Alcohol removes  grease and oil  stains as well as disinfects the windscreen surface

Though included in small quantities,  the above two alcohols aid in maintaining the liquid state of the water-beading windshield fluids during cold weather.

Polydimethylsiloxanes (PDMS): These are dual methyl groups attached to inorganic silicon-oxygen. The silicon-oxygen forms a  thin transparent coating on the windshield surface, and the attached methyl group repel against rainwater and compel it to bead up and fall off your windscreen.

A perfect example of the Water Beading Windshield Washer Fluids is the Rain-X White RX11806D Washer Fluid.

Pros

  • They create a transparent waterproof surface, which repels  rainwater and other types of fluid waste
  • Most products are available as additives, meaning  you can use them several times

Cons

  • The chemicals  in the formula may cause streaks on the windshield wiper blades as they age

4. De-Icing Windshield Washer Fluid

Rain-x 113645 De-icer & Bug Remover Windshield Washer Fluid, 1 Gallon (Pack of 6)

De-icing windshield washer fluids are formulated to provide effective windshield wiper fluid for use during cold weather extremes/ for use in cold areas without freezing. The anti-freezing compounds only inhibit freezing the wiper fluid and help remove some layers of ice on the windshield.

The commonly used ingredients in this type of fluid  include:

Power Cleaners like white vinegar  to penetrate and break grime and other unwanted elements

Antifreezing Compounds like ethylene glycol and methanol to prevent the fluid from freezing and breaking thin layers of ice off the windshield

Water Beading Agents to repel the accumulation of water on the windscreen

However, the higher concentration of anti-freezing agents in most de-icing wiper fluids leaves little room for most cleaning agents.  This reduces their efficiency in cleaning grime and other types of dirt. 

The Rain-x 113645 De-icer & Bug Remover Windshield Washer Fluid is an excellent example of de-icing wiper fluid.

Pros

  • They resist freezing up  to -49 degrees Celsius
  • Can thin transparent layers of frost on the  windscreen 
  • Water repellant

Cons

  • Not effective in cleaning grime and other dirt due to low  concentration of cleaning agents
  • Can cause streaks on the wiper blades
  • Costly options

Buyers  Guide: How  To  Choose A Windshield Wiper  Fluid For Your  Vehicle

Now that you understand the different types of wiper fluids available, the next thing is to familiarize yourself with how to choose the perfect wiper fluid for your vehicle. 

Below are the various factors to consider before you pick any wiper fluid.

Alcohol Content

Alcohol (whether ethanol, isopropanol, or methanol)  is an excellent anti-freezing agent. Suppose the temperatures in your region tend to dip below 0 degrees Celsius.

In that case,  you should go for fluids with a significant amount of alcohol to prevent the wiper fluid from freezing inside the vehicle’s storage chambers. Besides, alcohol is a  good disinfectant and a cleaner too. 

Reliability of  the Manufacturer

Some brands like Prestone, Rain-X, and NextZett have a well-laid record of producing quality wiper fluids while others are not.

I  recommend you to go for a brand whose products have been tested and verified to be of top-notch quality. Just visit the manufacturer’s site or social media pages and see what their past customers say about the product.

Non-Smear  Formula

Rain-X White RX11806D Washer Fluid Additive-16.9 fl. oz, 500. ml + 800002243 Yellow Windshield Treatment, 7. Fluid_Ounces

When looking for windshield fluids, the last thing you would like is to land a wiper fluid that leaves films of dirt on your windshield.

The best way to avoid this is to look for a formula with smear-free compounds like ammonia, white vinegar,  and other formulations to avoid the streaks. On the same note,  it is advisable to confirm whether the type of non-smear compound in your wiper fluid is ideal for use on your windscreen.

The formulas containing ammonia,  for instance, may not be safe for use in tinted windows.

I’m usually fond of Rain-X products because their wiper fluids, especially the ones formulated for use in cold weather extremes, never disappoint.

Season

What time of the year do you wish to use the wiper fluid? The standard wiper fluids are ideal if you are looking for a quality fluid for cleaning dirt off your windshield during summer and spring.

On the other hand,  the water beading options may be ideal if you are looking for a water repellant wiper fluid during rainy seasons. And if you live in areas with cold extremes,  then de-icing wiper fluids might do wonders for you. 

If you are tired of feeding your windscreen washer fluid reservoir with different formulas and are looking for an all-time solution for cleaning your windshield, then all-season wiper fluids are the perfect match for you.

Concentrate or Ready-Mix

Windshield cleaners can either come as a  concentrate or ready mix. I  highly advocate for the ready mixes, as they save you the time you may otherwise spend mixing the fluids. 

That doesn’t mean that there is anything wrong with the concentrated windshield fluids. But the chances of mixing the formulas wrongly while adding the concentrates are high. Go for concentrates only if you are an expert in mixing the wiper fluid.

When Do You Refill Your  Windshield Wiper Fluid

Some vehicles have indicators installed to notify you when the windshield washer reservoir is low or empty. And these indicators may either take the form of a written message, a symbol of wipers, or spray nozzles spraying water. You should refill the fluids as soon as you notice these signals.

If you are using a vintage car without the above signals, you must keep your eyes on the pressure of your windscreen nozzles. If the pressure is low, it could mean that the fluid level has gone down on the reservoir or there is a blockage in the nozzles. 

In that case, do not try to activate the windshield washer system anymore, as it may cause the pump system to overheat and fail.

Instead, stop your vehicle, and refill the reservoir. If the reservoir is full,  you might have to take your windscreen washer system for thorough inspection and repair by a specialist.

How  To Refill The Windshield Fluid

Refilling your windshield fluid reservoir doesn’t have to be complex. If your windshield nozzles aren’t releasing any fluid after activation, then perhaps your reservoir has gone empty. You can refill using the following procedure.

  • Open the  bonnet  of  your vehicle  to access the reservoir
  • Locate the reservoir cap (which features an image of water spraying on a windshield) to open  it
  • Carefully pour  the windshield fluid into the ironing of the reservoir until  it reaches the indicated full mark 
  • Replace the reservoir  cap
  • Close the vehicle hood, and  you are dining refilling the windshield washer fluid

However, mixing fluids that perform different functions might sometimes interfere with their chemical balance and negatively affect your wound screen.  Don’t attempt it unless you are an expert.  

Is there a difference between Winter and Summer windshield washer fluid?

Qwix Mix Windshield Washer Fluid Concentrate, 1 Bottle Makes 32 Gallons, 1/4 oz. Makes 1 Gallon 100% Biodegradable

The winter windshield fluids contain a  higher concentration of anti-freezing agents (alcohol), while the summer wiper fluids might contain little to zero alcohol.

In addition. The winter wiper fluid contains a low concentration of cleaning agents, while their summer counterparts are rich in cleaning agents.

Can I use water instead of windshield wiper fluid?

It is not advisable to use water instead of windshield fluids. Why? This is because water is devoid of cleaning agents, making it a less efficient cleaner. 

Additionally, water freezes at 0 degrees Celsius, which can freeze inside the reservoir and the pipes and damage them.  

Lastly, water might contain minerals,  clog the spray nozzles, and tendering the entire system non-functional.

Can you use glass cleaner as windshield wiper fluid?

No. You should not use glass cleaners to clean your windshield. This is because the ingredients in these formulations are exclusively meant for glasses and might be too harsh on the rubber and plastic components within the washer system.
