Detecting an unpleasant odor in the kitchen is a situation familiar to many housewives. Spilled milk, a forgotten piece of meat or a burst bag of fish can turn the life of the inhabitants of the house into a nightmare. At such a moment, it is important not to panic, but to act quickly and consistently to eliminate the source of contamination before it is absorbed into the plastic.
The first thing to do is to find and throw away the spoiled product. Often the source of the odor may not be obvious, such as something stuck in the back corner of the freezer or under the rubber door seal. After identifying and eliminating the cause, the scale of the disaster should be assessed: if the smell has just appeared, it will be easier to deal with it than if it has been ingrained into the porous structure of the plastic for several days.
In this article we will look at proven methods of how to clean the refrigerator from odor rotten products, using available means. You will learn which methods are most effective for different types of dirt and how to prevent the reappearance of an unpleasant odor in the future.
Emergency preparation for cleaning
Before you begin active odor removal, you need to prepare the unit for the procedure. Safety and efficiency —the main principles at this stage. Do not try to wash the device while it is on, as water and cleaning agents can damage the electrical components.
First, completely unplug the device. Then remove all food items, sort them out and put them in a cool place (for example, on a balcony in winter or in a thermal bag). All removable elements - shelves, drawers, containers - also need to be removed for a separate wash.
⚠️ Attention: If you live in an apartment building and cleaning takes a lot of time, try not to leave the doors open for too long to avoid distortion of the hinges or dust getting inside the cooling system.
To collect water that may leak during defrosting or washing, prepare old towels or absorbent rags. Place them on the floor in front of the unit. This will help keep the kitchen clean and prevent slipping.
Disassembly and primary processing
Removable parts of the refrigerator require special attention. The plastic and glass from which shelves and drawers are made can absorb odors, but they are easier to clean than the interior walls of the cabinet. Soak all removed items in warm water with dishwashing detergent.
Use a soft sponge to remove visible dirt. If there are traces of grease or dried food on the shelves, let them sit in a soapy solution for 15–20 minutes. This will soften the dirt and facilitate the cleaning process.
Rinse the parts thoroughly under running water. Make sure that there is no soap scum left on them, as it itself can give off a specific odor when drying. Dry the items with a clean towel before putting them away to air dry.
☑️ Preparing for washing
Folk remedies for odor removal
There are many ways to eliminate unpleasant odorusing improvised means. They often turn out to be more effective than expensive chemicals and safer for health, since they do not contain aggressive components.
One of the most popular methods is the use of baking soda. This substance is an excellent absorbent and neutralizes acidic and alkaline odors. To prepare the solution, dilute 2 tablespoons of soda in 1 liter of warm water.
Vinegar has also proven itself as a powerful remedy against bacteria and odors. Mix table vinegar with water in a 1:1 ratio. Wipe all interior surfaces with this solution. After treatment with vinegar, its own pungent odor may remain, but it will quickly disappear, taking with it the stench of spoiled food.
Why can’t you use bleach?
The use of chlorine-containing products (for example, Whiteness) can damage rubber seals and some types of plastic, making them brittle. In addition, bleach itself has a strong odor that is difficult to remove.
Activated carbon is another effective absorbent. Crush 10–15 tablets of black activated carbon, scatter the powder into saucers and leave inside a closed refrigerator for a day. Coal will absorb odor molecules from the air.
Household chemicals and specialized products
If traditional methods do not seem effective enough to you or you prefer ready-made solutions, the market offers a wide selection of household chemicals. It is important to choose products designed specifically for kitchen appliances and that do not leave toxic traces.
Specialized sprays for refrigerators often contain antibacterial components. They not only mask the odor, but also destroy bacteria that cause rotting. When using such products, be sure to follow the instructions on the package and rinse them thoroughly with water.
Ozone air purifiers are a modern solution for difficult cases. Ozone oxidizes organic compounds, completely destroying the source of odor. However, such devices must be used with caution, observing safety precautions.
⚠️ Attention: Never mix different cleaning products, especially those containing chlorine and ammonia. This can lead to a chemical reaction with the release of toxic gases that are hazardous to breathing.
When choosing household chemicals pay attention to the composition. Avoid products with strong fragrances if you or your household are prone to allergies. It is better to give preference to hypoallergenic options.
Technology for washing internal surfaces
The most important stage is the direct washing of the interior of the refrigerator. Here it is important to be thorough and get to hard-to-reach places where bacteria could accumulate.
Start washing from the top shelf and gradually work your way down. Use a soft cloth or sponge soaked in your chosen cleaning solution. Do not use hard brushes or abrasive powders, as they can scratch the plastic, and dirt will subsequently clog into these scratches.
Pay special attention to the rubber seals on the doors. It is in the folds of the seal that mold and food debris most often accumulate, which emit a persistent odor. Gently bend the elastic band and wipe it on all sides with a cotton swab dipped in a solution of vinegar or soda.
| Medication | Proportions | Exposure time | Efficiency |
|---|---|---|---|
| Soda solution | 2 tbsp. l. per 1 liter of water | 10–15 minutes | High |
| Vinegar solution | 1:1 with water | 5–10 minutes | Very high |
| Lemon juice | Juice of 1 lemon per 0.5 l | 10 minutes | Medium |
| Ammonia alcohol | 1 tbsp. l. for 1 liter of water | 5 minutes | High |
After treating all surfaces with clean water, wipe the refrigerator again. This will remove any residual cleaner and dissolved dirt. Allow the camera to dry naturally or wipe it dry with a clean cloth.
Eliminating odors in the freezer
The freezer has its own characteristics. Low temperatures preserve not only food, but also odors. If juice from meat or fish has leaked in the freezer, the smell can persist for a very long time.
To defrost the freezer, turn off the refrigerator and leave the doors open. Wait until the ice has completely melted. Do not use a hair dryer or other heating devices to speed up the process, as sudden temperature changes can damage the cooling system.
After defrosting, rinse the chamber with a solution of vinegar or soda. Pay special attention to the corners and joints of the panels where odor-bearing ice may have accumulated. If the smell is very persistent, you can use a solution of ammonia (1 tablespoon per 1 liter of water), but you need to work in a ventilated area and wear gloves.
In difficult cases, when the smell has ingrained itself in the plastic of the freezer, repeated treatment and prolonged ventilation. Sometimes placing a bowl of ground coffee or activated carbon inside the freezer for a few days helps.
⚠️ Attention: If the smell in the freezer appears due to defrosting food during a long power outage, check the condensate drainage system. Bacteria could have grown in the drainage hole.
Prevention and consolidation of the result
After successfully removing the odor, it is important to ensure that it does not return. Regular maintenance will help maintain freshness in the refrigerator and extend its service life.
Use odor absorbers. These can be special purchased devices or homemade analogues. For example, an open pack of soda, a jar of ground coffee or activated carbon left on a shelf will constantly filter the air.
Follow the rules for storing food. All products, especially those that have a strong aroma (fish, spices, smoked meats), should be stored in closed containers or cling film. This will prevent the spread of odors even if the product begins to deteriorate.
Wet clean the refrigerator at least once a month. This will take a little time, but will allow you to remove dirt in a timely manner and prevent the accumulation of bacteria. It is also recommended to defrost the refrigerator every six months (if it is not a No Frost system) and wash it completely.
Monitor the condition of the drainage hole. It is located on the back wall of the refrigerator compartment. If it becomes clogged, the water will begin to stagnate, which will lead to mold and an unpleasant odor. Clean it with a special brush or cotton swab as needed.
Can citric acid be used to clean a refrigerator?
Yes, citric acid is an excellent remedy. It removes scale and grease well, and also leaves a pleasant, fresh aroma. Dissolve 1 teaspoon of acid in a glass of warm water and wipe the surfaces. However, for very persistent odors of rotten meat, it may be rather weak compared to vinegar or soda.
How long does it take for the smell to disappear after cleaning?
Usually, with proper washing and airing, the smell goes away in 3-5 hours. If the smell has been left in the refrigerator for several days or weeks, it may take up to 24 hours for the odor to dissipate. The use of adsorbents (charcoal, soda) speeds up this process.
What to do if the smell does not go away after washing?
If the smell persists, it may have penetrated into the heat-insulating material of the case through microcracks or the drainage system. In this case, it may be necessary to disassemble the refrigerator and replace the insulation, which only service center specialists can do. Also check to see if the drainage hole is clogged.
Is it safe to use essential oils in the refrigerator?
It is possible to use essential oils, but with caution. Do not drop them directly onto the plastic, as the oils may dissolve some types of plastic. It is better to apply a couple of drops to a cotton pad and place it in an open container on a shelf. Oils of mint, lemon or orange freshen the air well.
