Refrigerator odors are primarily caused by volatile organic compounds (VOCs) released from decomposing food, with bacteria such as Pseudomonas playing a significant role. These odors persist because common deodorizing methods, like baking soda, only mask the problem rather than address it. A 2024 maintenance guide from Haier India emphasizes that unnoticed spills and forgotten food can lead to the formation of microbial biofilms, which continuously produce odor molecules. Effective odor management requires removing spoiled food and thoroughly cleaning surfaces to eliminate these biofilms. Research indicates that using mild detergents or vinegar solutions can reduce microbial presence by over 90%. Proper food storage and airflow management are also key to preventing odor buildup. Ultimately, households must shift their mindset from relying on quick fixes to prioritizing cleaning and maintenance, ensuring that deodorizers serve as supportive tools rather than primary solutions.
