Baking soda and washing soda are two handy household chemicals. You may be able to find washing soda with laundry supplies at the store, but if you can't find it, this is one chemical that's super easy to make from baking soda.
Make Washing Soda
- Pour baking soda into a cookie sheet. Spread it out to form a layer.
- Bake the soda at 400°F (200°C) for 30 minutes to 1 hour. The time isn't critical. You can't 'overcook' the soda, but you want to be sure to drive off all the water.
- Remove the pan from heat, allow the washing soda to cool, and store it in a sealed container to keep it from picking up moisture from the air.
How It Works
Baking soda is sodium bicarbonate (NaCHO3), while washing soda is sodium carbonate Na2CO3. When you heat baking soda, water (H2O) and carbon dioxide (CO2) are driven off, leaving you with washing soda.
