Bug Removal Washer Fluids

Washer fluids keep your windshield clean for optimal visibility and safe driving. All the washer fluids we’ve recommended here contain ingredients to cleanse bug debris from your car’s windshield. Additionally, potent cleansers remove bird droppings, dust, and grime. Several types of washer fluid are also freeze-resistant or include a de-icing ingredient for extreme winter temperatures.

When you walk into the parts department or any automotive store searching for your vehicle’s washer fluid, please read its label first. The label specifies whether the washer fluid is all-season and other particular cleaning functions. It should also show the lowest temperature the specific liquid can perform.

Can I Put Rain-X In Washer Fluid?

Yes. You can put Rain-X in washer fluid. Rain-X is an additive that you can add to your existing water fluid. It keeps your windshields clear by repelling water, thanks to the water beading technology.

How To Refill Windshield Washer Fluid?

First of all, purchase a container of windshield wiper fluid at a gas station, your local auto parts store, online, or even a big box store. Next, consult your owner’s manual for any suggestions or instructions on refilling windshield fluid for your specific vehicle. You can also check the manual to determine where the wiper fluid reservoir is located.

Follow these steps:

  1. Pop the hood of the car. 
  2. Locate the washer fluid reservoir, and remove the lid.
  3. Fill the reservoir to the fill-line by using a funnel to pour washer fluid slowly.
  4. Close the lid, and close the hood of the car.
  5. With the ignition on, or engine running, press the windshield washer fluid button to make sure fluid is running smoothly through the nozzles onto the windshield. 

What Can I Use Instead of Windshield Washer Fluid?

If you are looking for an environmentally-friendly solution to windshield washer fluid, or don’t have commercial fluid easily accessible, there are several options for you to make washer fluid by using ingredients found throughout your home.

Alcohol

Isopropyl alcohol (or rubbing alcohol) is freeze-resistant and clears dirt off windows effortlessly. It’s highly flammable, so please dilute with water; combine three cups of alcohol with a gallon of water. Rubbing alcohol does not freeze, so that you can use this in cold climates.

Water

Water can be used only in climates that do not experience freezing temperatures. If you’re using it in a freezing climate, a bit of isopropyl alcohol can keep it from breaking your fluid tank.

High Proof Vodka

Vodka works similarly to isopropyl alcohol. It does not freeze and should be diluted with water.

White Vinegar

Vinegar is an effective glass cleaner. It also won’t freeze in cold temperatures. However, due to vinegar’s acidity, it can potentially damage your car’s mechanical parts or paint. Dilute one part distilled white vinegar to three parts water.

Household Glass Cleaner

Combine one part of glass cleaner to three parts water, and add a spoonful of dishwasher fluid for extra cleansing capability. This recipe is not recommended for cold climates because these ingredients can freeze.

In Closing

Hopefully, this list will help you to narrow down the available options for windshield washer fluids that contain tough, bug-removing cleaning ingredients. As you have learned, several of these fluids also contain freeze-resistant ingredients to be used as an all-weather windshield washer fluid. Do take care to read the labels before purchasing windshield washer fluid. In a pinch, you can use water and add rubbing alcohol, high proof vodka, or distilled white vinegar to create an anti-freeze fluid.
