Another possible cause is expired condiments or other food items that have gone bad without you realizing it. Even if the main dish in your fridge is fine, an old jar of pickles or a bottle of salad dressing could be the source of the smell.

Fortunately, there are solutions to eliminate the bad smell in your fridge. The first step is to remove all the contents of your fridge and thoroughly clean it. Use a solution of warm water and mild dish soap to clean the shelves, drawers, and walls. Be sure to pay extra attention to any spills or stains that may be harboring bacteria. After cleaning, you can wipe down the interior with a mixture of equal parts water and vinegar to help neutralize any remaining odors. Finally, place an open box of baking soda or a bowl of activated charcoal in your fridge to absorb any lingering smells.
