I got the original of this recipe from my friend Faye, who got it off the internet. So, I did not come up with it on my own. But through trial and error, I adjusted it.

I use this because it is so very cheap. I just recently added the Downy Unstoppable because it makes it smell better, I love smelly, clean soap! A lot of people don’t use this because they don’t want those ingredients in their wash or they don’t like or cannot tolerate fragrance in their washing detergent.

Things you will need:

  • A 5 gallon bucket.
  • A bar of soap. (I use slivers left from the shower. So my soap bars are Iris Spring. Many people use Ivory because they want milder soap)  (No cost my way)
  • Borax (optional) ($5.19 for 76 ounces)
  • Washing Soda  ($7.57 for 192 ounces)
  • Downy Unstoppable In wash scent booster. ($6.97 for 13.2 ounces)

That is a total price of $19.73.  I am estimating that I make 12 buckets of laundry soap. I estimate that I can wash 12 loads or more of clothes per bucket. (12 if I am doing all large loads). 12 buckets times 12 loads is 144 loads. So that makes an estimated cost of each load $0.14. Pretty cool!  And easy. Plus I don’t run out of soap, I just make another batch!  I suppose I could run out if I did not buy my ingredients timely. But I do. 

So, I either carve little slivers or I use my vegetable peeler to cut up my soap and add it to a pan of about 4 -5 cups of hot water on the stove on medium to medium-high heat.  Stir it and check it to see that all the soap is melted.



Put 3 gallons of hot water into the bucket. I use a gallon pitcher to do this.

 Add the melted soap and water to the bucket and stir for a minute.

Then add one cup of washing soda and stir for another minute or so.

Next add 1/2 cup of Borax and stir some more.

Lastly add 1/2 lid full of Downy Unstoppable and stir again. (Shelia likes a lid full).

That’s it!  Let it sit over-night and it will turn into a kind of gel.

I use about 1.5 cups of this in a large load of laundry. I don’t stir the soap, it does not settle at the bottom.

I taught Shelia how to make the soap a couple of days ago, and she said it was so much easier than she had thought!

Enjoy your soap if you make it, but more than that, enjoy the money you saved!
