Here are the ingredients for the laundry soap:
1/3 bar of Fels Naptha (or Zote or Ivory)
1/2 cup of washing soda (not baking soda)
1/2 cup Borax
10 drops of Lemon essential oil (you can use whatever essential oil you would like for fragrance)
Grate the soap and put it in a large sauce pan. Add 6 cups of water and heat it until the soap dissolves. Add the washing soda and Borax and stir until it is dissolved. Remove from heat. Pour 4 cups of hot water into the pan and stir. Add 1 gallon plus 5 cups of water and stir. Let this sit for about 24 hours and it will gel. After 24 hours, put it into a large bucket. This recipe makes about 2.5 gallons of laundry soap - a cost of about .03 per load!
Use about 1/2 cup per load of laundry. Very easy and cost effective!
