How Do You Make Homemade Car Soap?
To make homemade car soap, you will need washing soda, borax, grated soap, essential oil, and hot water. Combine one cup each of washing soda and borax, and ½ cup of grated soap in a large bowl. Add ten drops of essential oil of your choice and mix all ingredients well. Boil 4 cups of water and pour it over the soap mixture. Stir until the soap dissolves. Mix the soap with about 10-12 cups of cold water to cool down the mixture. Store it in a container and use it to wash your car.
