Keep Baking Soda in the Fridge to Absorb Odors

Fridges accumulate smells — onions, cheese, leftovers, that forgotten container in the back. An open box of baking soda neutralizes these odors rather than just masking them. Sodium bicarbonate reacts with both acidic and basic odor molecules, effectively canceling them out.

Place an open box or a small bowl of baking soda on a shelf in the fridge. Replace it every 30 days for best results. The used soda is not wasted — pour it down the drain with hot water to freshen the pipes, or use it to scrub the sink. An almost-free solution that actually works.
