CRU’s Liquid Laundry Soap

CRU’s Liquid Laundry Soap was designed for those of us who have “those” washing machines that won’t fully dissolve powder soaps. This non-toxic soap is perfect for any home’s laundry needs.

  • 1 1/3 cups Arm-n-Hammer Washing Soda
  • 6 tbsp Baking Soda
  • 1 cup Dr. Bronner’s Castile Soap liquid
  • 10 cups Water boiled then divided
  • 10-20 drops Your Favorite Essential Oil


  • Bring 10 cups of water to a boil. Divide 5 cups into another container. 
  • Stir in the washing soda. Then, gradually add the baking soda to the washing soda and water (1-2 tbsp at a time). Making sure that you keep stirring and that everything is dissolving. 
  • The baking soda is going to act as a thickening agent. Keep whisking until all the baking soda is incorporated & dissolved.
  • Pour in the remaining 5 cups of boiling water. Now, add in the liquid castile soap. Stir well and allow to cool completely to room temp.
  • When it’s cooled, add in your favorite essential oils. You will find that the mixture is kind of like jello…you could whisk it, or just give the container a shake before each use, if you like.

CRU’s Liquid Laundry Soap was born due to the fact that I have a brand new washing machine…that won’t dissolve the powder detergent in ANY temperature. AHHHH!

Borax Free

You can look online for days over everyone’s opinion on Borax. There aren’t any studies done, but there are warnings on the label, “this product is an eye irritant and may be harmful if swallowed”.
Borax is actually a naturally occurring mineral. However, there are other naturally occurring elements (like arsenic) that we don’t need to be messing around with.
So, I opted to have a Borax-free household. It just makes me feel better, because I don’t want anything to harm my Dude, furbabies, or myself. My Dude & I won’t be chewing on our clothes or linens, but you never know with furbabies! And I do wash their soft toys with the laundry soap. It’s just safer this way.

How Much to Use

For large loads, I have been using 1/2 cup of detergent. Smaller loads, I use 1/4-1/3 cup. Not really any science behind these measurements…but they do work well.


Clean laundry shouldn’t be wreaking of strong smells or fragrances. It will just smell clean.
It will be void of chemical smells, stenches of mold or spoiled laundry smells, and any human odors that were made while using that laundry item (B.O., sweat, spit up, grease smells, etc).
Again, if you want to read more about what truly clean laundry is, and how to achieve it…please read here.
I hope you enjoy the liquid laundry detergent. You should also try my homemade fabric softener, too!
