Homemade Liquid Laundry Detergent

31 Days of Spring Cleaning DIYs: Liquid Laundry Detergent

Save some cash with day 20 of our 31 days of Spring cleaning DIYs challenge and make your own liquid laundry detergent. For the same cost of one container of store-purchased detergent, you can pick up the all-natural ingredients needed to make gallons and gallons of laundry detergent that costs pennies per load. And you can personalize this eco cleaning concoction with essential oils, leaving your clothes fresh and wonderfully clean.

What You'll Need:

  • Empty gallon jug
  • 1/2 cup Arm & Hammer Super Washing Soda
  • 1/4 cup Borax
  • 1 cup boiling water
  • 1 tablespoon castile soap
  • 1/4 cup distilled white vinegar
  • Hot water
  • Essential oils (optional)
  • Large mixing bowl
  • Whisk
  • Spouted measuring cup or funnel


  1. Measure and add the washing soda and Borax (both available in the laundry aisle at your local grocery store) in a large mixing bowl or container. Give the dry ingredients a whisk to break up any clumps.
  1. Cover the Borax and washing soda with the boiling water, and whisk until the dry ingredients have dissolved.
  1. Slowly add the pure castile soap. Castile soap can be found at your local health food store, and it comes in scented varieties, too. I used lavender for my liquid laundry detergent, which gave it a very slight floral scent. Then add the vinegar and gently mix.
  1. Add hot water while gently whisking until you have enough detergent to fill the gallon container. You can also add 10 to 20 drops of your favorite essential oil to personalize the scent. Using the funnel, carefully fill the container with the liquid laundry detergent.
  1. Now you're ready to do some laundry! Around 1/3 cup cleans a big load of clothes.
