Create Windshield Wiper Fluid

Non-toxic Windshield Wiper Fluid

You will need:

• 1 empty (clean) gallon jug
• 8 oz. isopropyl rubbing alcohol (high proof vodka can be substituted)
• 1 oz. liquid castile soap (where to buy liquid castile soap)
• 4 drops of blue food coloring (optional)

Pour the rubbing alcohol into the empty jug. Fill the jug with water, leaving room for the soap. Slowly add the soap and optional food coloring to the jug. Cap the jug and gently tip upside down a few times to mix ingredients. Pour windshield wiper fluid into the correct compartment under your car hood.
UPDATE: If you live in a colder climate, use 90% isopropyl alcohol in the winter to prevent the washer fluid from freezing.
