The detergent works. I, myself, haven't had the time or resources (got the soap, but not the other stuff) to make it yet, but my friend did and she is enjoying the fruits of her labor! She said that it works like any other store bought detergent! Still, I would emphasize to use a stain pre treater for those tough spots, but other than that, should be fine!
So, here is the recipe, since I never posted it before!
Liquid Laundry Detergent:
1/3 bar Fels Naptha Soap, grated (usually found in hardware stores or super market - and online)
3/4 cup Borax
3/4 cup Arm & Hammer washing soda (not to be confused with baking soda - in laundry aisle)
10 cups hot water, divided
16 cups cold water
Large container (preferably an old laundry detergent container)
In large saucepan, combine the grated soap and 6 cups hot water. Heat over medium heat and stir until soap melts. Stir in borax and washing soda until everything is dissolved. Pour soapy mixture in large container and add 4 cups hot water. Stir (or shake). Add 16 cups cold water and stir (or shake). Allow to sit uncovered for 24 hours to gel.
Use 1/2 cup per large load.
She said it was easy and cheap! Fun times. This is also the friend that made fabric softener, but she isn't as satisfied with that, so I will not be posting anything on it until we've found a recipe worth sharing.
Enjoy saving lots of money!!
