Fridge smells? Find spoiled food and spills before adding deodorizers
Start with spoiled food, leaks and unsealed containers when a refrigerator smells. Clean its interior as the appliance maker directs; baking soda may help with residual odor but cannot replace removing the source.
Whirlpool advises removing spoiled food and spilled liquids, cleaning shelves and drawers, then optionally using baking soda or activated charcoal for remaining odor. USDA notes that persistent odors can take repeated cleaning. Avoid leaving perishable foods unrefrigerated for long while you work.
