Find the Source of the Smell First
Bad fridge odors almost always have a clear source: forgotten expired or spoiled food, dried-up spills, or strong-smelling foods like durian, fish, and onions stored without sealed containers. Damp areas inside the fridge can also become breeding grounds for mold or slime.
Do not forget the door seals and ice trays. Mold on door seals is often the source of odors that keep returning even after the interior is cleaned. Old ice cubes can absorb odors too and are better thrown out.
Clean Thoroughly with Safe Ingredients
The first step is emptying the fridge. Check every container, throw out expired or smelly food, and set aside what is still good so nothing mixes. Remove the shelves and drawers, then wash them with warm water and baking soda. A mixture of 2 tablespoons of baking soda and 1 liter of warm water effectively removes stains and odors without chemicals.
Wipe all interior surfaces with a microfiber cloth dipped in warm soapy water, then wipe once more with clean water. Also clean the door seals and the drain hole at the back of the fridge, which can get clogged with food residue. Avoid using bleach since it is unhealthy around food.
Add Odor Absorbers and Keep Odors Away
Once the fridge is clean, place natural odor absorbers inside. Put a small open bowl of baking soda in a corner and replace it every 1-3 months. Other options: coffee grounds in an open container that also add a fresh aroma, activated charcoal that works stronger on stubborn odors, or lemon slices with mild antibacterial properties.
To keep odors from returning, store strong-smelling foods in airtight containers. Get used to checking the fridge contents weekly and discarding food past its prime before it spoils. Wipe spills immediately, as dried-up spills are the most common odor source. Do not overfill the fridge so cold air circulates evenly and food does not spoil quickly. With this simple routine, the fridge stays fresh every day.
