First, you need to determine the cause of the smell. It could be spoiled food.
Next, you need to fix the problem and wash the refrigerator. Once the shelves are dry, you can move on to other steps to eliminate the unpleasant smell from the refrigerator.
Regular baking soda is excellent at removing excess odors.
You need to mix it with a small amount of water, and then wash the shelves and walls of the appliance with the resulting paste. You can also put a cup with this loose product on the shelf.
In this case, the powder will absorb excess odors.
The soda in the cup needs to be refreshed periodically.
In addition, you can wash the refrigerator with a vinegar or lemon solution. Such products neutralize excess odors.
Experienced housewives note that it would not be a bad idea to put products on the shelves after cleaning that also absorb unpleasant odors.
For example, it could be half a raw potato, a piece of bread or ground coffee.
