  • Medium stock pot
  • Gallon size jar or plastic bottle with lid



  • In a medium-sized pot, bring 4 cups water to a boil. 
  • Remove from heat and add the borax and washing soda. Whisk to combine. 
  • In a separate bowl, combine the remaining water, castille soap and essential oils. 
  • Combine the borax mixture with the castille soap mixture. Pour into a lidded jar or old laundry detergent container.
  • Use 1/8 cup for small loads and 1/4 cup detergent for large loads of laundry.



I know some people aren't big fans of borax. Most of the studies used to prove borax's toxicity refer to ingestion, eye contact or prolonged undiluted use. In all my years of making my own laundry detergent, I have never had any issues with it. But if you would prefer not to use it, simply replace the borax with more washing soda.
Since this contains water, it should be used quickly. If you have a small family, halve or even quarter the recipe, and try to use it within 2 weeks.
