It's not alchemy exactly, but with just your oven and a baking dish you can convert baking soda to washing soda. Once it's ready, use it to deodorize, whiten laundry, remove build-up, soften water, and more.

Equipment
Large baking dish or cookie sheet with a lip around the outside
Spread 2-3 cups of baking across a large baking dish or baking sheet.
Bake for about an hour, stirring well at least once around the halfway mark. The baking soda needs to reach 400F in order to convert to washing soda, so the exact amount of time needed will vary based on whether your oven runs hot or cold, and how thick the baking soda layer is in your pan. Remove from oven when ready (see notes section for how to tell) and allow to cool before storing in an airtight container.

How To Know Your Washing Soda Is Ready
You'll know your washing soda is ready by its visual texture. Baking soda is light and fluffy, while washing soda is flat and grainy. In the photo above, washing soda is on the left and baking soda is on the right.It may be helpful to compare your washing soda with baking soda to see the difference until you get a feel for how long the conversion takes with your oven.
