Make Your Own Laundry Soap

DIY Laundry Soap

Making your own all-natural laundry soap is easier than you think, and it smells heavenly when scented with lavender or citrus essential oils. Our recipe will give you enough for 65 to 95 loads of great-smelling laundry.

What You Need

  • 4½ cups or 2 lbs of borax (such as 20 Mule Team Borax)
  • 4½ cups or 2 lbs of washing soda (such as Arm & Hammer Washing Soda)
  • 2 shaved-down bars of Dr. Bronner’s Pure-Castile Soap (choose citrus or lavender, depending on the scent you desire)
  • 10 drops of pure lavender or citrus essential oil


Powdered Laundry Soap

  1. Place all ingredients in a large airtight container with an easy-open lid.
  2. Make sure to mix the ingredients well so that they are all evenly distributed.

Liquid Laundry Soap

  1. If you want to make the detergent a liquid form, use the same recipe but add the shaved castile soap to about 6 cups of water and boil until fully dissolved.
  2. Remove from stove and add in the rest of the ingredients and stir together until fully blended.
  3. Let sit for about 10 hours or more, allowing it to thicken. This is a concentrated form, so you only need 2 ounces per medium load. This makes low suds, which means it’s good for both regular and HE washers.


  1. Both recipes yield just over 85 ounces of detergent or between 65 and 95 loads, depending on how much is used per load.
  2. We recommend using local, organic and non-GMO ingredients whenever possible.
