  • Gently stir to combine. As the mixture cools it should thicken up. If it's too thick, add more water and mix again.
  • Use 1/8 cup for small loads and 1/4 cup detergent for large loads of laundry.

Notes

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.
