Homemade Liquid Laundry Detergent

Clean Machine: Homemade Natural Liquid Laundry Detergent

A big pile of laundry waiting to hit the washing machine doesn't just inspire dread; doing all those loads starts to add up on the pocketbook, as well. With some premium liquid laundry detergents topping out around $10 for 12 ounces, tossing down the cash to keep those jugs full gets expensive. 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.

If you're finding the detergent starts clumping, try using grated Fels Naptha soap instead of the borax, which you can usually find it in the cleaning aisle of your local grocery store.

I love how easy this was to make and I love the results when using it, however, after a few weeks all of the borax and washing soda seemed to have undissolved and clumped together. I use a drink dispenser to dispense this and have noticed i have to stir it all back together before using it but the other day it had all clumped together so much that it was almost a goopy mixture. I put it on teh stove in a pot and brought it to a boil to redissolve the flakes which has helped but i'm sure it'll happen again. Did I do something wrong?
