12 Frugal Uses for Castile Soap

Castile soap is made from plant oils. It is a true soap and not a chemical detergent. Sometimes it’s called Olive Oil Soap or Marseille Soap. It comes in bar and liquid form and is a versatile product to keep on hand. It comes scented and unscented. Some scents are better suited for certain tasks; for example, you might prefer citrus scents for cleaning in your kitchen versus on your body, where you might prefer floral scents.

Keep in mind that if you’re using scented in the recipes below, there’s no need to include the optional scented essential oils.

One brand of Castile Soap is by Dr. Bronner’s. Dr. Bronner’s Magic Soap is popular, so I’ll share a bit of his history. According to, Dr. Bronner’s Magic Soaps are synonymous with Old World quality and time-honored simplicity, which can be traced back to the family’s German-Jewish soapmaking tradition. Born in 1908 to a Jewish family that had been making soap since 1858, Emanuel Bronner was the third generation certified as a master soapmaker under the guild system of the time. In 1929, he brought his formulas for high-quality liquid and bar soaps to America, starting Dr. Bronner’s Magic Soaps in its current form in 1948.
Here’s an interesting podcast about David Bronner.  But there are other brands and uses for Castile Soap available such as Desert Essence, Dr. Woods, Kiss My Face, Natural way Organics, Oregon Soap Company, Shadow Lake, Vermont Soap Organics, Carolina Castile, Kirk’s Natural, and Whole Foods Organic.
