Do you need to replace or refill your windshield wiper fluid? Well, if you’re looking for a cost-effective option that’s very easy to prepare, try this DIY tutorial that will show you how to make your own windshield wiper fluid!

Importance of windshield wiper fluid

A windshield washer is a vehicle-mounted device that sprays fluid on a car’s windscreen or other windows.
Its main function is to clean off dirt and debris from the surface before it becomes scratched by contact with another object like an insect, stone chip, or bug.

It also helps keep rain droplets from building up on the screen and creating a blurry vision for drivers in wet conditions. It can help make driving safer in inclement weather because a blurry windshield due to precipitation reduces driver safety significantly more than any added risk.

You can buy the wiper fluid in-store or you can make one yourself!

Benefits of DIY Windshield washer fluid:

1. Easy to make, with a few ingredients that one can find in their home.


2. Windshield wipers work much better than they would if the car owner had only used water on them before applying screen cleaner spray.


3. It’s cheap! The cost for the items needed equals about $0.25 per gallon and is cheaper than buying pre-mixed solutions which range from $0.75-$14 per 16 oz bottle (Source: WikiHow).

Materials to use

1. A container with a lid


2. A funnel to help pour the mixture in.


3. Two empty bottles, preferably plastic–one for your homemade fluid and one for rinsing out if you want later on.


4. Water and Dawn dish soap is what is used most often but there’s no set standard so use whatever cleaner you have handy!


5. A measuring cup or spoon that can measure in ounces.

IMPORTANT NOTE ABOUT SAFETY. If children live in your home make sure they do not come into contact with any of these products. They may cause eye irritation.

Step by Step DIY Guide

1. Measure out the water and Dawn dish soap into your container.


2. Fill it to about a third of its capacity.


3. Cap tightly, shake well, and then put in the funnel with one end open on top of the bottles for easy pouring later on.


4. Pour some mixture from your bottle where you measured it into a new empty bottle (preferably plastic) that will serve as storage for ready-made fluid until needed again or use right away!

Tip: Make sure not to pour too much at once. So that when using this DIY windshield wiper fluid, there is enough left over to rinse off any leftover residue.

Take care when opening the lid because pressure has built up!

The wiper fluid reservoir is typically located in the engine bay near the windshield. You can usually find it by looking for a bottle with an “H” or “antifreeze” label on its side. The cap has a wiper symbol on its surface. You may also find instructions to check the level of liquid inside. If you can’t find it, check your manual.

Most drivers often forgot to refill their washer fluid and complaint that the wiper nozzles won’t spray.

How much do these items cost?

1. Dish soap: $0.50 (depends on the amount or concentration)

2. Empty bottles (disposable is better): $0.15-$0.25 each

3. Water: free!


The total cost to make one bottle of windshield wiper fluid varies. It may cost from $0.75 – $ 0.95 per bottle depending on whether you used disposable or reusable containers. The kind of soap you use at home is also a factor.

This DIY Windshield Wiper Fluid recipe will last about six months in the garage. After that, it needs to be replenished with more plain water.
The key to making this solution strong enough for your car’s wipers depends on how often they are in contact with dirt/grime when driving through inclement weather conditions like rain and snow.

The wipers and windshield would need the assistance of wiper fluid to dislodge ice and melt it before being cleared off.

Hence, it’s important to add an anti-freezing agent to the DIY wiper mixture. Doing so will ensure that the fluid won’t freeze and clog some parts of your car most commercial windshield washer fluids contain methanol because it is a strong form of alcohol.

Rubbing or isopropyl alcohol (70% for not too cold weather conditions, while 99% for extremely low temperatures) would be the best choice. Vodka is also a great alternative- typically with 40% alcohol content.

How To Prepare a Homemade Windshield Cleaner With Vinegar and Alcohol

1. Mix equal parts of water and vinegar in a spray bottle.


2. Add enough alcohol to make it come out clear, but not too much that the washer fluid becomes excessively thin or is unable to freeze when temperatures drop below freezing point.


3. The mixture should be around 50% liquid and 50% alcohol.
