Ingredients

  • 4 cups distilled water – prevents mineral deposits on the windshield
  • 1 cup isopropyl alcohol (70% or higher) – helps prevent freezing and cleans effectively
  • 1 tablespoon liquid dish soap – cuts through grease and grime
  • Optional: 1 tablespoon white vinegar – enhances cleaning power and helps remove hard water stains
  • Optional: few drops of blue food coloring – for that classic windshield washer fluid look

Equipment

  • Large measuring cup or container – for mixing ingredients
  • Funnel – to pour fluid into the washer fluid reservoir without spills
  • Stirring spoon or stick – to mix ingredients well
  • Clean storage container with a lid – to store extra fluid safely
  • Gloves (optional) – to protect your hands from alcohol and detergent

Instructions

  1. Start by pouring 4 cups of distilled water into your large measuring container. Distilled water is preferred to avoid mineral build-up on your windshield and washer system.
  2. Add 1 cup of isopropyl alcohol to the water. This ingredient is crucial for lowering the freezing point of the fluid, especially in colder climates.
  3. Stir in 1 tablespoon of liquid dish soap carefully. Make sure to use a gentle dish soap without added moisturizers or antibacterial ingredients, as these can leave residue or damage your car’s paint.
  4. If you want extra cleaning power, add 1 tablespoon of white vinegar at this point. Vinegar helps break down grime and hard water stains effectively.
  5. Mix all ingredients thoroughly until the soap is fully dissolved and the solution looks uniform.
  6. For a traditional look, add a few drops of blue food coloring and stir again.
  7. Use a funnel to carefully pour the fluid into your car’s windshield washer reservoir. Avoid overfilling to prevent spillage.
  8. Store any leftover fluid in a sealed container away from direct sunlight and extreme temperatures. Shake well before each use if stored for a long time.

Tips & Variations

Important: Always label homemade fluids clearly and keep them out of reach of children and pets.

For winter use, increase the isopropyl alcohol to 2 cups to enhance antifreeze properties, but be cautious not to exceed this ratio to avoid damaging your car’s washer system.

If you prefer a more natural solution, replace the dish soap with a mild biodegradable soap, but keep in mind that cleaning power might slightly decrease.

For summer months when bugs and dirt are more prevalent, add a few drops of lemon essential oil for extra cleaning and a fresh scent.

Never use straight rubbing alcohol without dilution, as it can damage your vehicle’s paint and rubber components.
