How to Make Washer Fluid: A Step-by-Step Guide

Washer fluid is an essential component of any vehicle’s maintenance routine. It keeps your windshield clean and clear, ensuring that you have maximum visibility while driving. While you can easily buy washer fluid from any auto shop or gas station, you can also make your own at home. In this article, we’ll show you how to make washer fluid in just a few simple steps.

What You’ll Need

Before we get started, let’s go over the materials you’ll need to make your own washer fluid:

  • Distilled water
  • Rubbing alcohol
  • Dish soap
  • A large container with a lid
  • A funnel

Step-by-Step Guide

Step 1: Measure Out the Ingredients

First, measure out the ingredients. You’ll need:

  • 3 cups of distilled water
  • 1 cup of rubbing alcohol
  • 1 tablespoon of dish soap

Measure each ingredient carefully and pour them into a large container with a lid.

Step 2: Mix the Ingredients Together

Once you’ve measured out the ingredients, it’s time to mix them together. Use a spoon or a whisk to stir the mixture until everything is fully combined.

Step 3: Pour the Mixture into Your Vehicle’s Washer Fluid Reservoir

Using a funnel, carefully pour the mixture into your vehicle’s washer fluid reservoir. Be sure to fill it up completely.

Step 4: Test Your Washer Fluid

Now that you’ve filled up your washer fluid reservoir, it’s time to test it out. Turn on your vehicle’s windshield wipers and spray some of the fluid onto your windshield. If the fluid works well and leaves your windshield clean and clear, you’re all set!


What ingredients can I use instead of rubbing alcohol?

If you don’t have rubbing alcohol on hand, you can also use white vinegar or vodka as a substitute. These ingredients will work just as well.

Can I use tap water instead of distilled water?

We recommend using distilled water to make your washer fluid because it doesn’t contain any impurities that could clog up your vehicle’s washer fluid system. However, if you don’t have distilled water on hand, you can use tap water instead.

Can I add food coloring to my washer fluid?

While you can technically add food coloring to your washer fluid to make it a different color, we don’t recommend doing so. Food coloring can stain your vehicle’s paint and may cause damage over time.


Making your own washer fluid is a simple and cost-effective way to keep your vehicle’s windshield clean and clear. By following the steps outlined in this article, you can create your own washer fluid in just a few minutes. Be sure to test your washer fluid before hitting the road to ensure that it works well and keeps your windshield free from dirt and debris.
