So environmentally friendly vegan laundry powder does not come cheap! Well it does if you make it yourself! This recipe comes from the guru of DIY, DIY Natural. I quadrupled this recipe to make a larger amount. Borax I just found at the supermarket but the washing soda I got online from Walmart.
DIY Laundry Detergent
1 bar (or 4.5 ounces) of vegan bar soap (I used my own homemade soap but any vegan plain soap will do)
1 cup of borax (use a brand that does not test on animals such as Mountain Rose Herbs, Brambleberry)
1 cup of washing soda/baking soda (use a brand that does not test on animals such as Bob's Red Mill, Brambleberry or Mountain Rose Herbs)
Grate the soap and mix into borax and washing soda well.
If you like a cold wash, add the mix in batches to a food processor and pulse until the mix is finely ground.
Store in an air tight container with a small scoop.
Use around 1 Tbls per wash, or 2-3 Tbls for a large or heavily soiled wash.
