Ingredients for DIY Lavender Laundry Detergent

Each ingredient in this recipe plays a role in helping freshen and clean laundry while remaining easy to find and mix. Here’s what you’ll need:

Key Ingredients and Their Role in Laundry Cleaning

  • 2 bars lavender castile soap – A plant-based soap that blends well with the other ingredients.
  • 2 cups washing soda – Washing soda helps break down dirt, making it a great addition to any homemade laundry detergent recipe
  • 1 cup borax (optional) – Commonly used in laundry to support stain removal.
    Want a borax-free laundry soap? Simply replace borax with an extra cup of washing soda.
  • 1 cup baking soda – A multi-purpose ingredient that supports odor control.
  • ½ cup Epsom salt – Helps minimize detergent buildup in fabrics.
  • 10–20 drops lavender essential oil (optional) – Enhances the natural lavender scent.

These ingredients work together to create a simple, homemade laundry soap that can be stored in a jar or bin and used as needed.

Preparing the Ingredients

  1. Grate or Chop the Castile Soap
    – Using a cheese grater, grate the bars of castile soap into fine shreds.
    – If you prefer, a food processor can make this process quicker by pulsing the soap into small pieces.
    – Some people prefer to finely chop the soap with a knife instead of grating.
  2. Pre-mix Essential Oils (if using)
    – If you’re adding lavender essential oil, mix it with a few tablespoons of baking soda first.
    – This helps distribute the scent evenly throughout the detergent.

Mixing & Storing Your Homemade Laundry Detergent

  1. Combine Dry Ingredients
    In a large bowl, mix the washing soda, baking soda, borax (if using), and Epsom salt.
  2. Add Grated Soap
    Stir the grated soap into the dry mixture.
  3. Incorporate Essential Oils
    If using essential oils, add the scented baking soda to the bowl and stir well.
  4. Store the Laundry Soap
    To maintain the fresh scent in your lavender soap recipe for laundry, store it in an airtight jar in a cool, dry place.

How to Use Your New Detergent

  • For a standard load, use 1–2 tablespoons of detergent.
  • For larger or heavily soiled loads, use 2–3 tablespoons.
  • Some people like to add ½ cup of white vinegar to the rinse cycle to help soften fabrics and minimize residue.

What to Expect from DIY Lavender Laundry Soap

Homemade laundry soap can be a simple and rewarding way to customize your laundry routine.

  • A Light, Natural Scent – Unlike store-bought detergents, this version has a more subtle fragrance from real lavender essential oil.
  • Customizable Formula – Essential oils, additional boosters, or alternative soaps can be used to personalize the mix.
  • Small-Batch Friendly – This recipe can be easily adjusted for smaller (or larger!) quantities.

This DIY option may be a good fit for those looking for a straightforward laundry soap with simple, easy-to-find ingredients.

  1. Kylie,

    This looks like a wonderfully simple recipe! I have always looked for an easy DIY laundry soap, but never tried any of the recipes because they were too involved. Yours however looks so easy! Thanks for sharing, I can’t wait to try it.

    1. That was my concern too. Those HE machine are pretty tempermental when it comes to using the right washing product.

  2. I’ve been making my own laundry soap for the past two years but I miss that clean scent. This recipe looks good but I wonder about its lacking in laundry soda. I use arm & hammer brand. Is there a reason why you have not added this ingredient, for example, is it not safe? or does the oxiclean replace this ingredient? Your feedback is greatly appreciated.

    1. Hi Alexis,

      You could definitely add washing soda to boost this detergent even more, but I find that it works great for me without it. (And my husband’s clothes get really grimy at work!! Haha..)

      What brand of detergent did you use before? If you’re looking for more of a clean scent, try adding 1/4 cup white vinegar, 1/4 cup water, and 5 drops of an EO you like to your rinse cycle!

  3. I am now using this recipe as my go to detergent and love it–quick and easy to whip up!
    Essential oils add a nice fresh scent ( I have a top load washer and hang out laundry!!!)
    In past I have a recipe similar to this one but it did use borax and now am reading borax is being pulled from shelves here in Canada.
    This recipe cleans clothing and I love it!!
    Thank you for sharing
    Yvonne
