An unpleasant smell in the refrigerator is a problem that everyone has encountered. Sometimes the source is a spoiled product that you simply did not notice, and in other cases, the aroma is absorbed into the plastic after defrosting or purchasing new equipment. You cannot ignore this problem, since odors can be transferred to fresh products, making them unsuitable for consumption.
Before running for household chemicals, you must understand the nature of the origin of the aroma. Most often, the culprits are bacteria that multiply in hard-to-reach places, or residual liquid that gets into the drainage hole. The plastic from which the internal shelves and walls are made, has a porous structure, which facilitates the rapid absorption of odors, especially when it comes to fish, garlic or mold.
To effectively solve the problem, an integrated approach will be required. Simply wiping surfaces with water is not enough - you need special products that can break down organic compounds and neutralize odors at the molecular level. In this article, we will look at proven methods and products that will return freshness to your equipment.
Preparing for cleaning: safe defrosting and removal
The first step should always be to completely defrost the unit. Even if you have a model with the No Frostsystem, a preventive shutdown is necessary for thorough processing of all nodes. Turn off the device from the network, remove all products and remove removable elements: shelves, drawers, containers for vegetables. The temperature inside should be equal to room temperatureso that the cleaning agent works as efficiently as possible and does not crystallize on cold walls.
It is best to take the removed parts to the balcony or bathroom for washing under running water. This will allow you to use more aggressive products for plastic without fear of damaging the inside of the refrigerator. While the shelves are drying, you can work on the main body.
⚠️ Attention: Never use a knife or other sharp objects to chip ice. Damage to the evaporator will lead to a refrigerant leak and costly repairs.
It is also important to check the integrity of the rubber seals. It is in the folds of the profile that dirt and mold often accumulate, which give a persistent musty smell. Carefully bend the rubber and inspect the hidden cavities.
Folk remedies for eliminating odors
If the smell is not too strong or you prefer natural methods, the remedies that are in every kitchen will come to the rescue. They are safe for health and do not require rinsing with large amounts of water.
- 🍋 Citric acid or juice - perfectly breaks down fat and kills bacteria. Dissolve a packet of acid in a liter of warm water and wipe all surfaces.
- 🍞 Black bread - cut the loaf into pieces and place on shelves overnight. Bread works as an adsorbent, absorbing foreign odors.
- ☕ Ground coffee is a powerful odor absorber. It is enough to put an open jar inside to neutralize the aroma of fish or onions.
- 🧂 Baking soda is a universal remedy. A paste of soda and water can be used to clean complex stains, and leave the dry powder in a plate for prevention.
Deserves special attention acetic acid. It not only removes odors, but also disinfects surfaces. However, it must be used with caution, since the pungent odor of the vinegar itself may take longer to dissipate than the aroma of spoiled food. Mix table vinegar with water in a 1:1 ratio.
After treatment with any of the folk remedies, it is necessary to thoroughly ventilate the chamber. Leave the doors open for at least 2-3 hours, ensuring a draft in the room.
Household chemicals: how to wash plastic and rubber
When traditional methods do not seem effective enough, modern household chemicals come to the rescue. Not all products are suitable for cleaning the internal chambers of the refrigerator. Abrasive powders They can scratch glossy plastic, in the scratches of which dirt will then accumulate.
It is best to choose liquid gels, dishwashing sprays or special kitchen cleaning products technology. They must be pH neutral or contain antibacterial components. Products containing active oxygenwhich oxidizes organic residues.
| Type of product | Efficiency | Safety | Features of application |
|---|---|---|---|
| Dishwashing liquid | Medium | High | Requires thorough rinsing with water |
| Specialized spray | High | High | Often does not require rinsing, antistatic |
| Chlorine-containing products | Very high | Low | Dangerous for rubber, requires ventilation |
| Soap solution (laundry soap) | Medium | High | Can leave film, takes a long time to dry |
When using chemicals, be sure to wear gloves. After treatment, thoroughly wipe all surfaces with a clean, damp cloth to prevent chemicals from getting on food.
Cleaning the drainage system and hard-to-reach places
This often happens: you washed the refrigerator until it shines, but the smell remains. In 90% of cases the problem lies in the drainage hole. This is a small hole on the back wall through which condensate flows into a special tray above the compressor. Clogged channel leads to stagnation of water, mold blooms and the appearance of a persistent smell of dampness.
For cleaning, use a special brush brush (often included) or soft wire wrapped in cotton wool. Gently walk through the canal, removing mucus and dirt. Then pour some warm water with baking soda or hydrogen peroxide into it to disinfect the tube.
⚠️ Attention: Do not pour too much water into the drain at once. The liquid must have time to escape, otherwise it may overflow over the edge of the tray and end up on the floor or compressor.
Also check the condensate collection tray, which is usually located at the back of the refrigerator, at the bottom, above the motor. You can get there by moving the equipment away from the wall. The tray is often clogged with black mucus - this is a breeding ground for bacteria. It must be removed (if the design allows) and thoroughly washed with a chlorine-containing agent or soaked in boiling water.
☑️ Cleaning the drainage
How to eliminate the smell after defrosting or purchasing
A new refrigerator may smell like factory grease or plastic, and after defrosting, an “old” smell often appears. In the first case, it is enough to simply wash the equipment with water and vinegar and let it stand with the doors open for a day. Factory odors usually they disappear quickly.
If the smell appeared after defrosting, it means that bacteria remained inside. General cleaning using hydrogen peroxidewill help here. Pour peroxide into a spray bottle and generously spray all interior surfaces. Leave for 10-15 minutes, then wipe dry. Peroxide is an excellent oxidizing agent that destroys mold spores.
For the freezer, where odors are absorbed into the ice, complete defrosting will be required. You can't just scrape off the ice - you need to let it melt on its own. After this, rinse the camera with a soda solution. If the smell of fish or meat has ingrained itself in the plastic of the boxes, it is better to soak them in a basin with warm water and vinegar for several hours.
What to do if the smell does not go away?
If after thorough washing and airing the smell persists, it may come from the insulation inside the case (rare, but it happens with a manufacturing defect) or burnt wiring. In this case, you will need to call a specialist for diagnostics.
Prevention: how to maintain freshness for a long time
To prevent the question “how to clean the refrigerator” from arising every two weeks, follow simple operating rules. Store food in closed containers. Open food is the main cause of odors. Soups, sauces, chopped vegetables must be packaged.
Check inventory regularly. Throw away expired products immediately, without waiting for mold to appear. Once a month, wipe the shelves with a damp cloth, even without complete defrosting.
- 🌿 Use natural absorbents: a bag of rice, activated carbon, citrus zest.
- 🧼 Wash the rubber seal with soapy water once a quarter.
- 🌡️ Monitor the temperature - too high a temperature promotes the growth of bacteria.
There are special electronic and carbon air purifiers for refrigerators. They are battery-powered or rechargeable and ionize the air, killing bacteria. This is an excellent addition to manual cleaning.
Is it possible to wash the refrigerator with bleach (White)?
You can use chlorine-containing products, but with great caution. Chlorine is great at killing mold and odors, but it is aggressive towards rubber seals - they can crack and lose their seal. In addition, chlorine is toxic. If you used “Whiteness”, rinse it thoroughly and ventilate the chamber for a long time.
Why does the refrigerator smell rotten after washing?
Most likely, you did not get to the source of the smell. It may be hidden in the drain hole, under the plastic panels inside the chamber (if they are removable), or in the condenser tray on the back. Also, the reason may be an old, moldy container for eggs or vegetables, which you forgot to wash separately.
How often should you wash the refrigerator?
It is recommended to carry out general cleaning with defrosting once every 3-4 months (for a drip system) or once every six months (for No Frost). Preventative wiping of shelves should be done weekly or as they become dirty.
