I was so happy with my homemade vegan laundry detergent, that I decided to try a similar formula for dishwasher detergent.1/2 bar Dr. Bronner’s Pure-Castile Soap (any flavor) 1 cup Borax 1 cup baking soda
Grate the soap with a carrot grater or food processor. Place all ingredients in an airtight container and shake. Use 2 tablespoons per load. I have been using this recipe for a week now, and I am pleased with the results.
Notes: I used baking soda instead of washing soda because washing soda is not meant to be used on aluminum surfaces. Some recipes for dish detergent just call for Borax and baking soda – that combination alone did not thoroughly clean the oil off my dishes, but the addition of a little soap made it work well. We have an old dishwasher so we rinse our dishes before putting them in the dishwasher; I would be interested to see how this formula works in newer dishwashers without rinsing the dishes.
UPDATE 07/08/08: After using this for a few months, I have found that less soap flakes works better. I am now using 1 cup fluffy shredded flakes (or 1/2 cup compact food processed soap), 1 cup borax, and 1 cup baking soda. I think it 1 cup of shredded soap is about 1/4 of a bar.
