Is Your Baking Soda Fake? Here’s What Happens When It Expires—Don’t Miss This! Baking soda is a kitchen staple, essential for baking, cleaning, and even health remedies. But a question often asked by homeowners and home cooks alike: Is your baking soda still effective once it expires? The answer might surprise you—and could impact everything from your sourdough loaves to your homemade deodorant. ### What Happens When Baking Soda Expires? At first glance, baking soda (sodium bicarbonate) doesn’t spoil like perishable food. Unlike milk or yogurt, it doesn’t rot or grow mold—but it does lose its potency over time. When baking soda expires or sits too long (typically beyond 12–18 months), its ability to leaven bread, activate as a cleaning agent, or neutralize odors diminishes significantly.
