Conventional dishwashing liquids can be harsh on more than just your hands– phosphate-containing detergents are also hard on the environment. According to the National Institute of Environmental Health Sciences, hormone-disrupting chemicals found in conventional products such as dish soap may have developmental, reproductive, neurological and immune effects in both humans and wildlife. Either choose a CE-approved dish liquid or make your own! This dish wash is easy to make and uses nontoxic ingredients that will leave your dishes sparkling and your hands silky.

The citrus essential oils in this soap are great for cutting through grease while castile is a concentrated natural soap that provides cleaning power. Glycerin adds bubbles to your soap and softens your skin, and the kosher salt thickens to the perfect consistency.

Grapefruit & Lemon Dish Soap


  • 1 cup liquid castile soap
  • 2 tsp vegetable glycerin
  • 3/4 tsp kosher salt
  • 30 drops grapefruit essential oil
  • 15 drops lemon essential oil


  • 1 empty dish soap bottle or Mason jar with a pump lid


To an empty dish soap bottle or Mason jar, add all ingredients and 1/2 cup water; stir or gently shake until combined. (NOTE: The salt will settle to the bottom; shake the bottle a few more times throughout the day until it dissolves.)
