Liquid Castile Soap Recipe ~ An alternative liquid castile soap recipe can be made faster by grating a couple 4 oz. (118 ml) bars of castile soap and mixing it in a large pot with 4 cups of water. Stir until the soap pieces dissolve then add 2 tbsp. (30 ml) of vegetable glycerine. Continue stirring until the glycerine has dissolved. Transfer the soap to a jar and cover. You can use this soap right away.
