  1. Chop the bar of soap into chunks and place it in the food processor. Pulse it until it has a sand like texture.
  2. In a separate bowl, combine the borax and washing soda and mix well. Break up any large clumps. Set aside.
  3. Bring 4 cups of water to a rolling boil in a large pot over high heat.
  4. Pour the ground up soap from the food processor into the pot. Reduce the heat if necessary, but keep it at a gentle rolling boil. (Mine was on high heat the whole time)
  5. Stir almost constantly until the soap completely melts and dissolves, approximately 15 minutes. It will foam slightly (like in the pictures above). Watch the heat carefully and reduce if necessary. Don't let it boil over or you'll have a huge mess.
  6. Once the soap has completely melted, remove the pot from the heat and add the Borax and Washing Soda mixture, stirring constantly until the powder is completely dissolved, approximately 5 minutes. Stir until you can no longer feel a sandy texture on the bottom of the pan.
  7. Add 10 to 20 drops of the "Purification" essential oil and stir until combined.
  8. Pour the mixture into two 1 quart (4 Litre) mason jars, splitting it equally between the two jars.
  9. Add cold water to each mason jar to fill it to the shoulder of the jar, leaving about 1.5 inches of empty space at the top of each jar.
  10. Screw the lids on each jar tightly and turn the jars upside down. Allow to cool off, solidify and rest for 4 to 5 hours.
  11. After 4 hours has passed, remove the lids from the mason jars and attach your blender attachment to the jar (including the rubber gasket). Blend on low speed at first, gradually working your way up to high speed, for a total of about 1 minute. (If your blender bottom doesn't fit, you can use a hand held blender, or you can pour it into a large bowl and use a regular mixer).
  12. For both top loading and front loading washing machines, add 1 Tablespoon of this laundry sauce directly to the clothes. For very large or very soiled loads, use 2 Tablespoons.
