Isn't it nuts how easy it is?? I just started over the summer myself. I couldn't find washing soda around here and didn't want to order any, so I found a pin on Pinterest that showed how to bake regular baking soda at a lower temperature to convert it...pretty cool, and I felt like that was even cheaper than if I'd paid shipping on it!

Yes you can! That's what I have so I googled it haha
