Homemade Laundry Soap Recipe

Making your own laundry soap is a great step toward all-natural living. If you can skip the harsh chemicals, dyes, fragrances, and price tags of commercial laundry soaps, why wouldn’t you?

Luckily, making your own laundry soap is extremely easy; it only takes three basic products to make either liquid or powdered soap!


  • Washing Soda (available at most grocery stores)
  • Borax (available at most grocery stores)
  • Bar Soap (choose an all-natural soap such as Dr. Bronner’s, Ivory, etc.)
  • Optional: a couple teaspoons of baking soda can be added to freshen clothes

Recipe for Powdered Laundry Soap:

  • Grate the bar soap or mix in food processor until finely ground.
  • In a large bowl, mix 2 parts washing soda, 2 parts Borax, and 1 part grated soap (and baking soda if using).
  • Store in a closed container and use 1/8 – ¼ cup per load of laundry.

Recipe for Liquid Laundry Soap:

  • Grate one bar of soap with grater or food processor.
  • Put grated soap in a pan with 2 quarts water and heat gradually, stirring constantly until soap is dissolved completely.
  • Put 4.5 gallons of really hot tap water into a 5-gallon bucket and stir in 2 cups borax and 2 cups washing soda until dissolved.
  • Pour soap mixture from the pan into the bucket and stir well.
  • Cover and leave overnight. The next day, shake or stir until smooth and pour into containers of your choice.
  • Use ½ – 1 cup per load of laundry.

To achieve the scent you want, you can buy the bar soap in your desired scent. Alternatively, or if you decide to use unscented bar soap, you can add essential oils to your batch.
