Laundry Detergent - liquid

Prep Time

5 min

Cooking Time



32 oz to a gallon


  • 1 cup Dr Bronner’s liquid castile soap (any variety)
  • 1 cup baking soda OR washing soda
  • 2 cups + 3 cups hot tap water (plus more to top off the gallon)
  • 1/3 cup of sea salt, or other coarse grained salt
  • 1 gallon container (any clean jug or milk bottle works)


  1. In the gallon container, add 2 cups of hot water and stir in the baking soda and salt until dissolved. (It won’t dissolve completely.)
  2. In a separate container, add the castile soap to the 3 cups hot water, stir and pour into your gallon container. Pour it in slowly, stirring constantly to break up the gelling that will happen. 
  3. Fill the rest of the gallon container with hot water and stir to mix.
  4. Use ¼ cup of laundry soap per load.


I added a bit more washing soda to make it more gel-like.

You can divide the recipe by 4, and use an empty Dr. Bronner's bottle like I did.  Since I am the only one washing my clothes this way, it makes sense.

Shake before each use.
