Place 2 cups of washing soda into a large mixing bowl.
Add in 2 cups of baking soda to the mixing bowl. Combine the ingredients well.
Pour in 15 drops of lemon essential oil.
Add 15 drops of orange essential oil.
Stir the ingredients together until the oil has been incorporated well into the powder mixture.
Store the mixture in an airtight container of your choosing. When ready to use, place 1 tablespoon of the powder into the compartment in your dishwasher and set to wash as usual.
For best results, dishes should be pre-rinsed before placing into the dishwasher.
Notes
This should make about 64 tablespoons worth of detergent!
