Making your own windshield wiper fluid

To make your own windshield wiper fluid, gather the necessary ingredients and follow a simple recipe. A popular DIY recipe includes mixing equal parts of isopropyl alcohol, white vinegar, and distilled water. Add a small amount of dish soap to the mixture to help with cleaning the windshield effectively. This homemade windshield washer fluid is a cost-effective alternative to store-bought options and works well in cleaning your windshield.

When preparing your homemade wiper fluid, it’s essential to consider freezing temperatures. To prevent the fluid from freezing and potentially damaging your wiper system, ensure that the solution is suitable for cold weather by adjusting the alcohol to water ratio. Test the fluid in your car to see how it performs in cleaning your windshield effectively without leaving streaks or residue.

Storing and using your homemade wiper fluid

When storing and using your homemade windshield washer fluid:

  • Ensure labeling and safe storage practices to prevent accidents and maintain effectiveness.
  • Store the homemade windshield washer fluid out of their reach and consider using childproof containers.
  • Keep the fluid in an area with a moderate temperature to avoid freezing or spilling.
  • To enhance visibility, add a drop or two of blue food coloring. Avoid using water only as it can cause smearing and bacterial growth. 
  • When mixing the solution, work in a well-ventilated area, wear gloves and a mask when handling chemicals like ammonia.
  • Shake the container to thoroughly mix the solution. Use a clean gallon container for mixing and opt for distilled water to prevent mineral deposits. 
  • Never mix bleach with wiper fluid as it can damage your vehicle and create hazardous chemical reactions.

Consider using white vinegar as a safe and effective cleaner for your windshield wiper fluid, especially in moderate temperatures and heavy pollen conditions. If you’re looking for a homemade, environment-friendly option, vinegar is a great choice.

To make the solution, dilute one part distilled vinegar with three parts water. Keep in mind that vinegar may have a strong odor. Ensure you use white vinegar to prevent residue on your windshield.

Why Make Homemade DIY Windshield Washer Fluid?

Save money and protect the environment by making your own DIY windshield washer fluid at home.
