Why Make Your Own Laundry Detergent?

There are a few reasons I choose to make my own laundry detergent.  Store-bought laundry detergents have many chemicals & even carcinogens in them.  The fragrances are overpowering and can be harmful to your hormones.  Also, the prices are getting more and more expensive for the name brands.

Making your own natural laundry detergent is healthier & more cost effective.  It is also easy to make and will last you for many months, and maybe even years depending on how often you wash laundry.

Ingredients In Natural Laundry Detergent

Each ingredient in this recipe is unscented and great for cleaning clothes. When combined together they are a powerhouse to clean, remove stains, and deodorize your laundry.

You can mix and match some of the ingredients in your laundry detergent.  If you’re out of one of the ingredients, you can go forth with making the detergent without it. 

Here is a list of the 4 ingredients used:

  1. Washing Soda – natural detergent booster and freshener to help remove stains & odor
  2. Baking Soda – is used to deodorize and remove stains from clothes
  3. Unscented Castile Soap – natural soap to clean dirt and leave clothes feeling fresh
  4. OxiClean Baby or OxiClean Free – removes stains and safe to use on colors

How To Make Your Own Natural Laundry Detergent?

To make the laundry detergent, you will need to grate the Castile soap into small specs.  I used a large kitchen knife to slice the bars of soap into small cubes and then ran them in the food processor. You can also manually grate it with a cheese grater.

After you grate the Castile bar soap, you simply combine all of the ingredients together and mix them well.  You’re ready to start washing clothes!

How To Use Natural Laundry Detergent?

When you’re ready to wash your clothes, you will use 1-2 tablespoons of the detergent powder in your washing machine depending on the size of the load.   I use a heaping 2 tablespoons if I have a really large load or a really smelly load to wash.

You’ll place the detergent like normal in your washing machine in the compartment for powder detergents. It will leave the clothes clean and odor free!  After you wash the clothes, then you’ll dry like normal.  Check out my All-Natural Dryer Ball Spray for a natural alternative to dryer sheets as well!

*Extra Tip: For a natural fabric softener while washing, fill your tray with white vinegar. I promise, you won’t smell it on the clothes when they’re finished!

  1. I used to make my own laundry detergent with similar ingredients. But overall decided to stop because it was actually laundry soap, not detergent, and my clothes were really never getting clean! I did not consider using castile soap, however, I didn’t even know it existed in bar form. Thanks for the thoughts! You’ve piqued my interest!

    1. The baking soda works great on the odors. I also put a few tablespoons of vinegar in the wash to help get rid of anything that is causing odors.

  2. I have been making my own similar to your recipe for years and can only recommend it! It’s cheaper, cleaner, and works just as well as commercial detergents!
