A Box Of Baking Soda In The Fridge Or Freezer Does Not Absorb Odors

This is a very clever and successful marketing ploy by the baking soda people, but the fact is that baking soda is very poor at absorbing odors.

It seems to make sense, however, so lots of people have spent untold billions of dollars to put boxes of baking soda in their fridge or freezer to no effect.

Activated charcoal would work much better but is expensive. Better to wrap your food and clean the fridge once in a while.
