Question: is all baking soda aluminum free?
Answer: Baking soda does not contain aluminum. I even called the Arm and Hammer (the “famous” baking soda company) to double check, and they stated very definitively that their baking soda is 100% sodium bicarbonate and contains zero aluminum. Whew. ... However, all baking soda is aluminum-free, even if it is not labeled as such.
