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)
~ 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?
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 centsWashing 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.
