I just noticed..The Seattle Free School had a recipe for laundry soap on the back of their handout.
Obviously, I haven't tried it so no guarantees.
Homemade Laundry Soap
Ingredients:
1 Bar Soap
1 cup Washing Soda (not to be confused with Baking Soda)
1 5-Gallon Bucket with lid
3 Gallons of Water
Directions:
Grate the bar of soap into a sauce pan. Heat up some water in a kettle and cover the soap with boiling water. Leave overnight to melt. If there are still chunks of soap in the morning add more boiling water until all chunks of soap are gone. Pour melted soap mixture into the bucket. Add enough hot tap water to make 3 gallons of liquid and then add the washing soda. Stir well and let sit overnight. Use 1/2 to 1 cup of the mixture per load of laundry at a total cost of approximately $0.03 per load.
Washing Soda can be found at the Ballard Fred Meyer.
