How Long Does Baking Soda & Baking Powder Last in Mylar Bags?

Quick Answer: Baking soda lasts indefinitely (30+ years) in mylar bags. Baking powder only lasts 1-2 years as the leavening agents lose potency. Store baking soda long-term and baking powder for rotation only. Add desiccant to prevent clumping.
