For millenia, Castile soap referred to soap made using olive oil. Today a variety of fruit and vegetable oils are used to create this gentle, versatile cleaner. Olive oil is still one of the primary ingredients in this mild version from Oregon Soap Company. We love this all purpose product because it’s tough enough to clean your home (There are many recipes on line for mixing Castile soap with water and anti-bacterial essential oils to make all-purpose spray cleaner, or with baking soda to make a paste for tough stains.) However, don’t mix with vinegar or lemon juice, as each will cancel out the cleaning action of the other! It is also very gentle on skin and great for hand soap and body wash. Ours is a ‘soap base’ that is concentrated, so dilute with water to your desired level of lather. Vegan, non-toxic, safe for babies and pets, and very versatile, Castile soap can save money and replace dozens of products in your home.
