Windshield Washer fluid (make-it-yourself)
2 cups rubbing alcohol
1/4 teaspoon liquid dish soap
water to fill a gallon jug
blue food coloring (optional)
Mix and pour in the tank under the hood of your vehicle.
Costs 30 cents per gallon to make...... cheapest I've found to buy is .97 cents....saves 67 cents & tax.
Good to know when 'every penny counts!'
