Powder Laundry Detergent

It’s easy to make your own laundry detergent! Our DIY powder laundry detergent is about a tenth the price of using store-bought laundry detergent and creates a mix that is free of dyes and perfumes.


1 Kirk’s Fragrance Free or Original Fresh Scent bar soap

1 cup washing soda

1 cup Ecos Oxo Brite

1/2 cup kosher salt


  1. Working in a well-ventilated area, cut the bar soap into chunks.
  2. Fit a shredding blade in a food processor. Add soap chunks and process.
  3. Fit the food processor with a chopping blade. Add remaining ingredients.
  4. Process to a very fine powder.
  5. Store in a container with a tight-fitting lid.

Makes 3 cups.

Add 2 tablespoons per load to top- or front-loading high-efficiency (HE) washers. Use 1/4 cup for regular top-loading washers. Adjust the amount based on your laundry needs. Pretreat stains.

Add 1/2 cup distilled vinegar to the rinse cycle or in the fabric softener compartment.

Add drops of essential oils, such as lemon or lavender, to wool dryer balls or a clean cloth in the dryer, if desired.
