Ingredients

• 4 cups distilled water (tap water can leave mineral spots)
• 1 cup isopropyl alcohol (70% or higher) – acts as antifreeze and cleaning agent
• 1 tablespoon liquid dish soap (mild, biodegradable preferred)
• Optional: 10-15 drops of essential oil (lemon or eucalyptus) for scent
• Optional: 2 tablespoons white vinegar (for extra cleaning power)

Equipment

• Large measuring cup or pitcher
• Mixing spoon or stirrer
• Funnel (for easy pouring)
• Empty, clean container (preferably with a lid) for storage
• Gloves (to protect skin from alcohol, if desired)

Instructions

1. Prepare your workspace. Make sure your mixing container is clean and dry. Wearing gloves is optional but recommended when handling isopropyl alcohol.
2. Measure the distilled water. Pour 4 cups of distilled water into your mixing container. Distilled water helps prevent mineral buildup on your windshield.
3. Add isopropyl alcohol. Carefully measure and add 1 cup of isopropyl alcohol to the water. This ingredient lowers the freezing point and helps remove grime.
4. Mix in liquid dish soap. Add 1 tablespoon of mild dish soap. The soap breaks down dirt and grease on your windshield for a streak-free finish.
5. Optional additions. If you want your fluid to smell fresh, add 10-15 drops of your favorite essential oil. For extra cleaning power, stir in 2 tablespoons of white vinegar.
6. Stir gently but thoroughly. Mix all ingredients until well combined. Avoid creating too many suds.
7. Use a funnel to pour. Transfer the fluid into your car’s washer fluid reservoir or a storage container using a funnel to prevent spills.
8. Test your fluid. Spray the windshield washer and check for streaks or freezing. Adjust the alcohol content if necessary for colder weather.

Tips & Variations

“For winter months, increase the isopropyl alcohol to up to 2 cups to prevent freezing down to -20°F. Just be careful not to use too much, as it can damage rubber components.”

• Eco-Friendly Tip: Use biodegradable dish soap to reduce environmental impact.
• Fragrance Variation: Try peppermint or lavender essential oils for a unique scent experience.
• Vinegar Alternative: Lemon juice can also be added for its natural cleaning properties and fresh smell.
• Storage: Keep your fluid in a labeled, sealed container away from children and pets.
• Winter Adjustment: For extremely cold climates, mix 3 cups water with 3 cups isopropyl alcohol to increase freeze resistance.
