All Natural Laundry Liquid


  • Super Washing Soda – (2/3 cup)
  • Baking Soda – (3 Tbsp)
  • Liquid Castile soap – 1/2 cup, any scent
  • Water– 5 cups, divided


  1. Bring 5 cups of water to a boil.
  2. Pour washing soda into a large glass bowl then slowly stir in 2 cups of boiling water until washing soda is completely dissolved.
  3. Add one tablespoon of baking soda at a time and stir well to combine. The mixture will thicken as baking soda is added until it is a pudding-like texture.
  4. Stir in ½ cup Castile soap until well combined.  Slowly stir in remaining 3 cups of boiling water.
  5. Cool to room temperature, the mixture will separate while cooling. (I let my detergent rest overnight.)
  6. Combine separated mixture by blending or whisking until smooth.
  7. Store liquid detergent in a glass bottle. Use 1/3 cup per load of laundry.

Notes on Using Laundry Detergent Liquid with Castile Soap

  • If the detergent sits for an extended period of time it may separate, stir or shake to combine.
  • The detergent has a thin gel-like consistency, pour directly on top of clothes instead of using your liquid detergent dispenser.
  • Use vinegar in the rinse water for extra softness. Add it to the fabric softener dispenser.
  • Make sure to fully dissolve the washing soda completely while making or the detergent will be gritty.
