A refrigerator runs continuously to keep food safe, but it can only do its job effectively when the interior is kept clean and organized. Small spills may seem harmless at first, yet they can become sources of odors, cross-contamination, and bacterial growth if left unattended.
Food safety experts emphasize that temperature and cleanliness work together. According to the FDA, refrigerators should be maintained at 40°F (4°C) or below to help slow bacterial growth and reduce the risk of foodborne illness. But what’s the best way to keep the fridge clean? To help you create a safer food-storage environment, here’s how to clean a refrigerator properly.
1. How to Clean a Refrigerator Properly?
A thorough cleaning is usually easier when approached in stages rather than trying to clean around food containers and shelves.

While emptying the refrigerator:
- Check expiration dates.
- Discard spoiled food.
- Consolidate duplicate items.
- Identify containers that may be leaking.
