Clean A Bad-Smelling Refrigerator
Another place that holds a lot of fresh, cooked, and opened food, is the refrigerator. Therefore, you can’t be surprised if it begins to smell not-so-fresh as days and weeks go by. To kill the smell inside your fridge, sprinkle baking soda across the shelves and leave for three days before cleaning out with water.
It does sound messy. If the work seems too much, you can just leave an opened box of baking soda inside the fridge for three days instead. It will still do the job of absorbing the bad smell.
