If the odor in your refrigerator is too strong, the best thing to do is remove everything that is in the refrigerator and discard all the foods that are spoiled. Spoiled food generates a strong, penetrating smell that is quite unpleasant. Decaying food also may affect other foods that are close or below on the lower levels inside the refrigerator.
In these cases, there is no choice but to do a thorough cleaning of the fridge, removing and cleaning all the shelves, compartments and drawers in the fridge. With the inside the refrigerator empty, clean the floor, walls with water and soap or detergent and a few drops of bleach or hypochlorite. At the end of cleaning, rinse with plenty of water and dry it well.
To remove odors from the refrigerator that are normally caused by some types of foods, follow some of these tricks and tips:
Put foods that naturally have a strong odor in plastic bags. Always place leftover food and sauces in closed containers. Roasted coffee placed in a cup and put inside the fridge will neutralize odors. The same effect is produced by a lump of coal. Another trick to remove the bad smell in the fridge is to make some balls with bread crumbs soaked in vinegar and place them on a plate inside the refrigerator.
