I have been making soap for a couple of years now, but have never made laundry soap. Here a recipe I have heard good things about. I am going to give it a try today.
Liquid Laundry Detergents
3 Pints Water
1/3 Bar Fels Naptha Soap, Grated
1/2 Cup Washing Soda
1/2 Cup Borax
2 Gallon Bucket
1 Quart Hot Water
Mix Fels Naptha soap in a saucepan with 3 pints of water, and heat on low until dissolved. Stir in Washing Soda and Borax. Stir until thickened, and remove from heat. Add 1 Quart Hot Water to 2 Gallon Bucket. Add soap mixture, and mix well. Fill bucket with cold water, and mix well. Set aside for 24 hours, or until mixture is gelled. Use 1/2 cup of mixture per load.
