Introduction
A smelly refrigerator is unpleasant and can affect the taste of your food. Bad odors in your fridge are usually caused by spoiled food, spills, or bacteria growth, but they can also come from less obvious sources like the drip pan or interior components.
Understanding how to eliminate refrigerator odors helps you maintain a fresh, clean appliance and prevent food contamination. This guide covers effective cleaning methods, natural deodorizers, and prevention tips to keep your fridge odor-free.

Solution:
