INGREDIENTS
16 cups water
1 cup borax
1 cup washing soda
1 cup Castile soap (liquid)
Essential oil (optional)
INSTRUCTIONS
Bring 8 cups of water to a boil. While your water is boiling, add one cup of borax and one cup of washing soda to a large jug or bucket. Mix well.
Add one cup of liquid Castile soap, then add the 8 cups of boiling water and mix it well to dissolve all the ingredients.
Once it’s well mixed and the ingredients have fully dissolved, add another 8 cups of cold water and mix again.
At this point, you can add some essential oils if you like. If using essential oils, I like to add about 50 drops and then mix all of the ingredients together one more time.
Let your laundry detergent sit until it cools to room temperature. Depending on the temperature, it may remain liquid or it may congeal to a thick white consistency. To use, add about ¼ cup of laundry detergent to each load.
