Several months ago I was desperately searching for a source of washing soda to attempt a recipe for homemade laundry detergent. To no avail. Grocery stores, craft stores, bulk retailers, none of them had washing soda. Most of the people I talked to didn't even know what I was referring to. (Frankly, I didn't either...) So, in a desperate attempt I went online and did some research. Low and behold,
washing soda is incredibly easy to make.
I found
this recipe for making my own.
All you need is baking soda and an oven. It's that simple because,
Baked Baking Soda=Washing Soda
The difference, chemically speaking, between baking soda (NaHCO3) and washing soda (Na2CO3) is water and carbon dioxide. When you heat baking soda at a high temperature the water and carbon dioxide evaporate.
How To Make Washing Soda
Preheat your oven to
400 degrees. Sprinkle a layer of
baking soda on a baking sheet. Place in the oven. Stir occasionally
for about an hour (or longer if need be). Remove from the oven and let cool. You can tell it is done based on texture. Baking soda is wet and clumps. Washing soda is dry, grainy and flakes (In the picture, the baking soda is on the left and the washing soda is on the right). See the difference?
Now, if you ever come across recipes for homemade detergent that calls for washing soda, you don't need to drive anywhere to get it!
What do you I use it for?
