4 Ingredient Laundry Soap

There is something really satisfying about making my own products. I love knowing that laundry detergent isn’t some mysterious blend of ingredients that only the people at Tide know how to do. It gives me a sense of accomplishment that I know a few homesteading essentials. This recipe not only saves our family money but it also works just as good, if not better than our old store brand.


  • 8c. borax
  • 8c. baking soda
  • 8c. super washing soda
  • 3 bars of original Ivory soap (grated…designate an inexpensive grater for this)

Mix all ingredients together in a big bucket or bin (I purchased my bucket at Ikea and found a cast iron scoop at a local antique store). Use 2 Tbsp per load.

As an alternative to Ivory, you can purchase soap flakes that  are already grated for you from your local health store.

This recipe lasts 6 months for our family of five and ends up costing us only pennies per load.

  • I want to make my own detergent but I love the smell of gain how can I make detergent to smell almost like it

    • Hi Mallari,

      I’m with you! I love the fresh smell of laundry and will often use my favourite essential oils to add scent. You can either add essential oils (approx. 20-30 drops) to the baking soda before mixing with the rest of the ingredients or put 5-10 drops into the compartment reserved for bleach before each load.

      But your question did get me thinking of some alternatives. I came across some helpful information suggesting Gain Fireworks fragrance booster, which you would add to each load along with your DIY detergent. Hope that helps! Let me know how it turns out!

Any thoughts? I'd love to hear from you!
