Each batch yields approximately 32 ounces (between 32-64 loads based on how many Tbsp used per load).
1 cup of borax
1 cup of washing soda
Thoroughly stir together for 5 minutes and enjoy the results! You can take this a step further and blend the mixture in a blender or food processor to create a powder that will dissolve easily even in cold water. (Just be sure to let the dust settle before removing the lid of your blender or food processor so you don’t inhale the fine particles.) Store in a sealed container with a small scoop.
Use 1 Tbsp per load (or 2-3 Tbsp for large or heavily soiled loads).
