Let’s explore the causes of these unwanted smells and discover how to keep your refrigerator and freezer smelling delightful. Reasons for Bad Odors in Refrigerators and Freezers Spoiled Food The most common cause of bad smells in a fridge is decomposing food. Forgotten leftovers and expired items, especially fruits and vegetables, can rot and emit strong, foul smells. Regularly checking and disposing of expired foods is essential to prevent these situations. Spills and Stains Leaked liquids from food containers or packages, such as soups, broths, and juices, can seep into refrigerator shelves, creating persistent odors. These spills can leave behind stains that, if not promptly and thoroughly cleaned, produce bad smells over time. Bacterial growth in these spills also contributes to unpleasant odors. Regular cleaning and prompt attention to spills can prevent these issues.

Dirty or Clogged Drains Refrigerators often have drain holes that can become clogged with food particles and debris, leading to musty or sour smells. Additionally, condensation drains can harbor bacteria and mold if not regularly cleaned, contributing to unpleasant odors. Regular maintenance of these drains is crucial to prevent such issues.
