This is a hypoallergenic dish washer powder recipe. It is soy, coconut, and surfactant free, with no mixing required. Most dishwasher detergents have many ingredients, making it hard to find something that is both environmentally friendly and allergy friendly.

First we fill the detergent cup to the line with Vitamin C powder: Bulk Supplements Ascorbic Acid (multiple sizes available)
Then we fill the remainder of the cup and half the pre-wash compartment with washing soda: Arm & Hammer Washing Soda
For the rinse aid compartment we use organic distilled vinegar. But for a more powerful rinse you could use 6% cleaning vinegar: Heinz Cleaning Vinegar
