Homemade laundry detergent is eco-friendly, easy to make and is so much cheaper than conventional detergents. These are just a couple of the reasons I like to make homemade laundry detergent. Here is a great recipe that you can use to make your own laundry detergent. This is the powder detergent recipe, and the liquid laundry detergent recipe is coming up in my next post.

You can scroll down to the bottom for the cost break down.

Ingredients and Supplies

  • 1 Bar of Soap (castile)
  • 1 cup Borax
  • 1 cup Washing Soda
  • Measuring Cup
  • Cheese Grater
  • Container (big enough to hold 4 cups of powder)
  • Metal Fork
  • Optional: 10-15 drops of essential oil (tea tree, lavender etc…) I use tea tree oil because of its natural antimicrobial and antibacterial properties, plus it has a nice scent to it.
Love essential oils? I’m a self-proclaimed oil-junkie! Read up on the brand of essential oils I absolutely love and currently use for everything from warding off strep, to eliminating my daughter’s asthma.

Directions for All Natural Powder Laundry Detergent

Step One: Grate your soap with a cheese grater. The finer the better, because the finer it is the faster it melts and the better it works. I chose to use a pure-castile, unscented soap, but you could experiment and try others if you like. I’m trying to be as natural and eco-friendly as possible with this, so the castile soap seemed like the perfect choice for me.

Step Two: Mix together grated soap, borax and washing soda and blend well with a fork. You might have a few clumps to break up.

Step Three: At this point you can add in your essential oil if you’ve decided to use some. Make sure it blends really well with your fork, and break up any added clumps caused by the oil.

Step Four: Store in an air-tight container out of reach of children, and use 2-3 tablespoons of the powder in your washing machine.


As an added tip, use one cup of vinegar in your rinse cycle (put it in the fabric softener slot) to eliminate any residue on your machine, and naturally soften your clothes. Vinegar is something I use in the rinse cycle, no matter the detergent I am using.

While these ingredients are non-toxic and eco-friendly, you should still handle them with care and keep out of reach of children. They are not meant to be consumed either.

It’s super easy and cheap to make your own laundry detergent when you use this powdered laundry detergent recipe. I use this powder, and find that it gets my clothes clean just fine. I use a front-loading, high efficiency washing machine. If you are concerned about how this powder will affect your clothing, then test a small hidden area with the detergent before washing.  My clothes have always turned out just fine, and I’ve not noticed any added fading or wear and tear on my clothing.

Stay tuned for my liquid laundry detergent recipe that is coming up tomorrow, and on Friday I will be answering all your questions with a video – so let the questions and comments fly!
