I have actually been making powdered laundry soap for about 6-9 months now; I definitely say that it rates as a repeat activity.
I started making my own laundry soap for a couple of reasons: I like the idea of a lower cost alternative, I wanted to be more of a do it myself mom & the “natural” soap is a bonus
when I first looked into this idea I was inspired by the Duggar’s and all of their frugal ways to raise a family. The recipe I use comes from their family resources section.
1 Fels-Naptha soap bar
1 Cup – Arm & Hammer Super Washing Soda
1 Cup Borax
Grate soap or break into pieces and process in a food processor until powdered.
Mix all ingredients. For light load, use 1 Tablespoon.
For heavy or heavily soiled load, use 2 Tablespoons.
Yields: 3 Cups detergent. (Approx. 40 loads)
The Fels-Naptha and Arm & Hammer Super Washing Soda in my experience are not always easy to find. I have ordered both online using the Ace Hardware website to store free shipping.
I have also heard by never tried, that if you talked with the manager at your local grocery store they might carry items on request.
I have used Colgate’s Octagon soap in the place of Fels-Natptha; it is also an all purpose laundry bar soap. The recipe also states that you could use Ivory, Sunlight, Castile Soap or Zote bars as an alternative to the Fels-Naptha.
This recipe costs about $2 a batch and yields about 40 loads
at my local grocery store: Purex 32 loads = $4.99 and Tide 32 loads = $8.39
that makes this recipe a cost saver of about $3-6
however to get started you would have to buy more product than just one batch:
Arm & Hammer Washing Soda – 55oz = $3.99
Borax – 76oz = $4.99
Fels-Naptha = $3.00
