Clear the air and bring back a pleasant scent to your refrigerator with lemon juice!
First, remove any odor culprits from the fridge such as spoiled foods. Place strong smelling foods such as onions and fish in airtight containers. Next, soak a few cotton balls in freshly squeezed lemon juice and place them in a small, open glass container. Place the container in the fridge for four to six hours. Repeat every few weeks or as soon as you notice bad odors.
