Frugal Living – Homemade Laundry Soap

Mom's Super Laundry Sauce

Mom’s Super Laundry Sauce

I just got done making a double batch of laundry soap.  I’m always so excited about my savings and about how well the recipe I use works but I really HATE the actual process of making the soap.  I make a very concentrated formula so the smells completely overwhelms me while I’m making it.  I also hate standing over the stove stirring the soap.  But on the positive side, I know exactly what is in the laundry soap, it has minimal fragrance, it works really good and it’s super duper cheap!

I’ve tried lots of recipes over the years as I’m allergic to most commercial laundry soaps.  I find a recipe that I love and then sure enough a short while later the clothes start smelling terrible.  If you google search this you will find this to be the case for many do it yourselfers.  Some of them really leave the clothes not clean – funky smell.  What I’ve noticed is that when too much of the soap is used it doesn’t wash out properly.  Also not all of the homemade soaps dissolve properly in the washer.  It’s important to use a homemade soap recipe that dissolves easily in water.

I have finally found a recipe that I love!  Mom’s Super Laundry Sauce at

The ingredients are simple:

  1. 1 bar Fels Naptha
  2. 1 cup 20 Mule Team Borax
  3. 1 cup Arm & Hammer Washing Soda
  4. 4 cups hot water

I bought the first 3 ingredients at Walmart.  They were all located in the laundry section.  Prices were quite affordable

  1. 1 bar of Fels Naptha is $.97
  2. 1 box of 20 Mule Team Borax is $3.97 (76 oz = 10 cups)
  3. 1 box of Arm & Hammer Washing Soda is $3.24 (55 oz = 5.5 cups)

Super Washing Soda, Fels Naptha, 20 Mule Team Borax, and Purex Crystals has a great walkthrough on how to make this laundry soap so definitely go check out their site to make this great soap.  I’ve been using this recipe for a year now and I love it.  I wash about 15 loads of laundry a week so have gone through a lot of this.

TIP 1:  What I’ve learned to make this process easier is to have your supplies ready.  Nothing sucks more than stirring the soap and it being ready and then realizing you haven’t mixed the washing soda and borax together. 

TIP 2:  This tip will save you a bunch of time but it’ll make your house stink!  The Felps Naptha can be dried out in the microwave which makes it crumble.  What I learned is that you should cut it into small blocks and space these out on a paper plate.  Microwave for 1 minutes 45 seconds.  Let cool down before touching because it’s very hot.  Izzy stated it looked like rice crispy treats.  As long as you’ve spaced the soap chunks out the microwaved soap will crumble quite nicely.

TIP 3:  After melting, mixing and stirring the soap is poured into two mason jars.  I learned that when you turn the soap over to separate that if you’ve done it correctly it’ll start to separate right away.  If it’s not separating then dump it all back in the cook pot and heat it some more. It really makes a difference to have it separate properly.

We have an ice cream scoop that holds about a tablespoon of the soap.  I also use Purex Crystals Lavender Blossoms because I love the scent.  When we have a smelly load we add a scoop of Sun Oxygen Cleaner.
