How to Make Homemade Laundry Soap Detergent

How to Make Homemade Laundry Soap Detergent.
Laundry detergent seems to get more expensive every time you go to the store.  Instead of paying big companies you can make laundry detergent yourself for much less. This not only saves money but will allow you to know exactly what goes into your laundry soap, helping you to avoid unnecessary chemicals, dyes and perfumes.  This is of great benefit to those with sensitive skin or who suffer from allergies.

Homemade Laundry Soap Detergent


1 bar of Ivory Soap, grated

1 cup washing soda (sodium carbonate)

1 cup borax

5 gallons water

5 gallon bucket with lid

Empty liquid detergent or fabric softener container

Step One

Put the grated bar of Ivory soap in a pan with a quart of water.  Heat on medium and stir until the soap is completely melted.  

Step Two

Put 3 gallons of the water in a five gallon bucket and stir in the borax and washing soda.  

Step Three

Add the melted soap mixture to the bucket and stir well.

Step Four

Add the rest of the five gallons of water to the bucket.  Make sure you leave enough room in the bucket to allow for stirring.  

Step Five

Cover the bucket and let it sit for a day to cure.

Step Six

The next day stir the mixture well, breaking up any clumps and thickly gelled areas.

Step Seven

Fill the empty detergent or fabric softener container half full with the laundry soap mixture, and top off the container with water to make a 50% solution.  Shake well to mix.

Step Eight

Use 5/8 cup of this homemade laundry soap detergent per load of clothes.


  • Only use pure soap like Ivory, Zote, Fels Naptha, Octagon, lye soap, etc.  If you use Fels Naptha soap, only use 1/2 bar.  All the others use a whole bar.  Do not use detergent bars like Lever 2000 or other brands--your laundry soap will not be as pure. Ivory Soap is the mildest, but Fels Naptha has a reputation for cleaning heavily soiled items.
  • Washing Soda is commonly sold under the Arm & Hammer brand name.  You can also find it in the pool care section under the name "PH Increaser."  Check the ingredients to verify that you are purchasing sodium carbonate.  Baking Soda is NOT the same.
  • This recipe makes 10 gallons of laundry soap detergent.
