Hello, I make my homemade laundry detergent out of a mixture of 3 gallons of water, 1 cake of Fels Naptha soap, 1 cup of washing soda and 1 cup of 20 mule team borax. It works great. We live on a farm in West Virginia and the mud is a foot deep in spots, especially when feeding the horses.
Everything I wash in this stuff comes clean. I hope that this information is helpful to you. Joyce
