Recipe for Homemade Laundry detergent:
1 bar Fels-naptha soap
1 cup Borax
1 cup Washing Soda
5 gallon bucket
Grate the bar of soap. Heat it in a large pot with 6 cups water, stirring til dissolved. Turn off heat and add Borax and Washing Soda. Stir well. In the 5 gallon bucket, pour 4 cups very hot water. slowly add in the mix, stirring every so often. Stir well. Fill bucket with warm water leaving 3 - 4 inch headspace. Stir well. Let sit 24 hours. You will have a thick portion of gel on top with liquid underneath. Ask your husband to stir it, really well. :) All done.
Use about 1/2 cup per load. If washing cloth diapers, use about 1/4 cup per load. I let my washing machine fill up half way with the detergent in it, and then I add clothes.
