Make your own laundry soap

I had a friend over for breakfast the other morning and we got to talking. She told me that she makes her own laundry soap for about seventy-one cents and it lasts for sixty-four loads. That works out to a little over a penny a load! I am going to try the recipe this week...I'll update you on how it works but until then, here's the recipe:

1/3 bar of Ivory, Zote, or Fels Naptha soap, grated

1/2 cup washing soda

1/2 cup borax powder

1/2 to 1 ounce of essential oils for fragrance (optional)

water

~ small bucket, about 2 gallon size ~

Place grated soap in a saucepan. Add 6 cups water and heat it until the soap melts. Add the washing soda and the borax and stir until it dissolves. Remove from heat. Pour 4 cups hot water into the bucket. Now add your soap mixture and stir. Now add 1 gallon plus 6 cups of water and stir. Let the soap sit for about 24 hours and it will gel (not a solid gel, more of a watery gel). You use 1/2 cup per load.

**I am not planning on using my homemade laundry soap on my cloth diapers. I'm afraid that the borax might ruin the covers. Anyone have thoughts about this?


The Math:

Fels Naptha: $1.12 for a 5.5 oz bar. The recipes says use a 1/3 of a bar. I calculated 2 oz. just to make the math a little easier. The cost of the Fels Naptha per batch is: .40 cents

Washing Soda: $2.23 for a 55 oz. box. This came to .17 cents per batch. I calculated how much per oz (2.23 divided by 55) and then weighed a half cup of washing soda (4.2oz.) and multiplied my per oz. price by 4.2

Borax: $3.27 for a 76 oz. box. This came to .14 cents per batch. Did the same calculations as above, however a 1/2 cup of borax weighs 3.5 oz.

For the final numbers I have .40 + .17 + .14 = .71 for 2 gallons of laundry detergent.
