Make your own disinfecting counter spray, mop your floors, and even wash your dishes with our handmade organic castile soap. Castile soap is commonly defined as any natural soap (either bar or liquid) that is processed with almost entirely vegetable oil. Because it contains NO SYNTHETIC FOAMING AGENTS, it is milder for the skin than sulfate-loaded body washes and is universally used for body care as well as laundry and household cleaning.
