Or you can use this simple trick to turn your baking soda into washing soda.  Baking Soda is “sodium bicarbonate” and washing soda is “sodium carbonate.”  Slowly cooking the baking soda causes the chemical reaction to turn it from bicarbonate to carbonate.  Here’s how its done:

  1. Preheat your oven to approximately 400 degrees Fahrenheit.
  2. Pour a box of baking soda onto a baking sheet, spread evenly over the pan and put it in the oven.
  3. Bake the baking soda for 60 minutes. It usually takes anywhere from 45-75 minutes just to assure that the chemical reaction is complete.  You will be able to see the difference in the two sodas.
  4. After pulling the baking sheet out of the oven and letting it cool, store the washing soda in an airtight container. The washing soda can turn back into baking soda if it’s exposed to air for too long of a time.

That’s it!  Pretty cool and cheap way to get washing soda if you cannot find it at your local store!
