Homemade Laundry Soap

Making homemade laundry soap is easy.  This is a recipe a friend taught me and I’ve been using it to make homemade laundry soap for a couple of years now.  It takes me about ten minutes once a month.  We have six boys and multiple loads of laundry every day, so you may not have to make it so often.

Homemade Laundry Soap

You need:

  • Sauce pan
  • Large 1.5  gallon (11 liter) bucket and/or a large plastic container from purchased liquid laundry detergent
  • Borax
  • Washing soda (not the stuff you cook with, this is found in the laundry aisle)
  • Fels Naptha laundry bar soap (or another brand)

Homemade Laundry Soap


1 1/2 gallons water

1/3 bar Fels Naptha Laundry Bar Soap, grated

1/2 cup Borax

1/2 cup Washing Soda


  1. Add six cups of water to a saucepan and heat over medium heat.
  2. As the water heats grate 1/3 of a bar of Fels Naptha soap (or another laundry soap brand) into the water. Stir.
  3. Once the soap is dissolved into the water, add Borax and Washing Soda. Stir till dissolved. Remove from heat.
  4. Add 4 cups of water to a large bucket or plastic laundry liquid dispenser. Pour in your laundry soap and stir.
  5. Add another gallon of water, plus six cups and stir. Let it cool.
  6. Use 1/2 cup of laundry soap per load.
  7. Optional: You can add essential oils or scents to the laundry soap if you like.

The soap can gel up quite a bit after it cools.  I shake it really well with a cap tightly in place to break it up then pour it out the spout instead of from the spigot.

It really gets your clothes clean just as well as commercial laundry soaps and you can avoid allergens and additives.  The other thing I like is the low cost.  It’s astonishing how much water goes into liquid laundry soap.  Making it myself also makes it easy and affordable to store larger quantities of laundry soap ingredients right on the shelf above my washing machine.

    Here is another recipe.

    Quick and Easy Laundry Detergent
    3 tablespoons borax
    3 tablespoons washing soda
    2 tablespoons original Blue Dawn
    Find a one-gallon container with a tight-fitting lid. Pour in the borax, washing soda and liquid Dawn. Add two cups of very hot water. Apply the lid and shake until the soda and borax have dissolved. Now fill the container with cold water. Reapply the lid, label and you’re done. To use: Add 1 to 2 cups to each load of laundry depending on the size and soil levels.
    This recipe multiplies so well, I make three gallons using this conversion which is slightly more concentrated:
    3/4 cup borax
    3/4 cup washing soda
    3/4 cup original Blue Dawn
