Store your washing soda in an airtight container, such as a mason jar or old (clean) coffee container.
The chemical difference between washing and baking soda is that baking soda has a hydrogen atom that washing soda doesn’t, and it’s missing one of the sodium atoms.
Use about one-half cup (125 grams) of homemade detergent per load. If you can’t find laundry or soap flakes, purchase a bar of pure soap (like glycerine or Castile soap) and grate it.
Don’t use this detergent on aluminum, as the high alkalinity can damage the metal.
Use this to clean floors, bathrooms, toilets and showers, kitchens, or anywhere else that’s dirty or grimy.
