In modern times, almost every household owns a refrigerator. However, if it’s not cleaned properly or used correctly, it can develop unpleasant odors. A smelly refrigerator not only affects the taste and freshness of the stored food but can also pose health risks. Therefore, it’s important to regularly clean it, remove spoiled food, and wipe the interior thoroughly. In addition, you can try the following simple and inexpensive deodorizing tips to keep your fridge smelling fresh.

1. Use sea salt

Sea salt is not only an inexpensive seasoning but also has great odor-removing and moisture-absorbing properties. Placing a small bowl of sea salt inside the fridge regularly can help eliminate odors. Moreover, salt won’t affect the taste or smell of other stored foods.

2. Citrus peels (grapefruit, orange, lemon)

The peels of grapefruit, oranges, or lemons contain natural essential oils that help neutralize unpleasant odors. They’re also good for your health, so don’t throw them away after eating citrus fruits.
You can place the peels on the refrigerator door shelves or in the compartments. They’ll absorb odors and release a pleasant, refreshing scent. Once they dry out and lose their fragrance, replace them with fresh peels.

Storage tips to prevent refrigerator odors

Improper food storage is a major cause of unpleasant smells. Always wrap food tightly using plastic wrap or airtight containers to prevent odors from spreading. Cooked foods should be sealed before refrigeration.

When arranging items, leave enough space for airflow—use only about 70% of the fridge’s capacity. Overloading it can restrict air circulation, create clutter, and increase the risk of bacterial contamination.
