1 tablespoon dish soap (mild, non-foaming like Dawn)
1/2 cup rubbing alcohol (isopropyl, 70% or higher — helps prevent freezing)
Instructions:
Pour the distilled water into a clean gallon container.
Add the dish soap and rubbing alcohol.
Mix gently to combine — avoid creating too many suds.
Use a funnel to pour the mixture into your vehicle’s windshield washer fluid reservoir.
❄️ Winter/Freezing Weather Version:
If you live in a cold area, increase the amount of rubbing alcohol:
Use 1 cup of isopropyl alcohol (or more, depending on how cold it gets — up to 99% alcohol works best below freezing).
You can also substitute methanol (Heet gas line antifreeze in the red bottle) for better freeze protection — just handle with care and avoid breathing the fumes.**
