Suddenly appearing unpleasant odor in the refrigerator can ruin the mood of any owner. Often we notice the problem too late, when the aromas have already been absorbed into the shelves and rubber seals. This signal cannot be ignored, because it indicates the growth of bacteria or the presence of spoiled products.
There are many reasons for the appearance of amber: from accidentally spilled juice that has flowed under the drawer to failure of the ventilation system. Plastic of the internal walls has a porous structure, which facilitates rapid absorption smells. If measures are not taken, even fresh food will soon acquire a strange taste.
The first thing to do is to audit the contents. Throw away anything that has gone bad, even if it hasn't expired yet. Sometimes one piece of moldy cheese is enough to poison the atmosphere in the entire cell. Only after complete cleaning can you begin to eliminate the consequences.
⚠️ Attention: Do not try to mask the stench with air fresheners without eliminating the source. This will only create an explosive mixture of aromas that will make you sick.
Finding and eliminating the source of the problem
Before grabbing rags, you need to understand where the “aroma” comes from. Often the culprits are vegetables forgotten in the far corner or meat that has fallen behind a container. Carefully inspect every corner, including door shelves and areas under trays.
If the source is not visually found, check the condensate drain system. In some models, for example Liebherr or Electrolux, the hole may become clogged with mucus, which, when heated, emits a specific smell of rotten water. You can clean it with a cotton swab or soft wire.
Pay special attention to the rubber seals on the door. Food debris and mold often accumulate in the folds of the material. They must be peeled back and washed with special care. This is where colonies of microorganisms most often hide, causing a persistent odor.
General cleaning: step-by-step instructions
Effective fight against odors is impossible without high-quality washing. You will need to completely defrost the unit, if you do not have a system No Frost, and remove all removable elements. It is better to wash shelves and drawers in the bathroom or under the shower with warm water.
☑️ General cleaning checklist
For washing, use warm water with the addition of a mild detergent. Aggressive chemistry may damage the plastic or leave its own pungent odor, which will then have to be removed separately. Rinse surfaces thoroughly with clean water.
After washing, be sure to wipe all surfaces dry. A humid environment is an ideal condition for the development of bacteria. Leave the refrigerator open for at least a couple of hours to allow it to dry and ventilate completely. Only after this can you plug it into the network.
Folk remedies for neutralization
If mechanical cleaning does not help completely, time-tested absorbents will come to the rescue. They are gentle, safe for products and are often on hand. These methods are especially effective at removing residual flavors.
- 🍞 Brown bread: Cut the loaf into slices and place on shelves for a day. Bread perfectly absorbs foreign odors.
- ☕ Ground coffee: pour fresh coffee into bowls and place around the chamber. It will not only remove the stench, but also add a light coffee aroma.
- 🧂 Salt or soda: an open pack of soda or a bowl of salt work as a powerful natural filter.
- 🍋 Citrus fruits: orange or lemon peels will freshen the air, but they need to be changed every two days so that they do not rotted.
Using vinegar also gives excellent results. Wipe the walls with a solution of water and vinegar in a 1:1 ratio. This will disinfect surfaces and remove greasy deposits. The main thing is to ventilate the refrigerator well after the procedure so that the smell of the acid itself goes away.
Household chemicals and special products
The modern market offers many specialized sprays and gels for refrigerators. They contain antibacterial ingredients and are often flavored with food. Such products are convenient because they do not require rinsing.
When choosing a chemical, pay attention to the composition. It is better not to use chlorine-based products, as they can be toxic and take a long time to wear off. The optimal choice is preparations based on hydrogen peroxide or enzymes that break down organic matter.
| Medicine | Efficacy | Safety | Duration of action |
|---|---|---|---|
| Soda food | Average | Absolute | Up to 1 month |
| Vinegar solution | High | High | Up to 2 weeks |
| Special. sprays | Very high | Average | Up to 1 week |
| Ozonator | Maximum | High | Constantly (during operation) |
Do not forget that any chemicals must be used with caution. After treatment, be sure to let the surface dry and ventilate the chamber. Never mix different cleaning products, this can lead to a chemical reaction and the release of harmful gases.
Technical causes of an unpleasant odor
Sometimes the problem lies not in the products, but in a malfunction of the device itself. If the inside smells like burnt wiring or rubber, this is a warning sign. The compressor may have overheated or the wire insulation has melted.
In models with the system No Frost the smell may come from the melt water removal system. If the drainage tube is clogged, the water stagnates and begins to go out. In this case, it is necessary to disassemble the rear panel and clean the channel, which is best left to a specialist.
⚠️ Attention: The smell of burning requires immediate disconnection of the device from the network. Operating such a refrigerator can lead to a fire.
It is also worth checking the condition of the light bulb. If it burns out or the contacts melt, a specific smell may appear. You can replace the lamp yourself by selecting one that is similar in power and base.
What to do if a smell appears in a new refrigerator?
New appliances often smell like plastic or factory grease. This is fine. It is enough to wash it with water and soda and let it stand open for 24 hours.
Prevention of odors
To prevent the problem from returning, it is important to follow the rules for storing food. All liquids must be covered, and meat and fish must be sealed. Check expiration dates regularly and throw away suspicious stock.
Use storage containers. They not only save space, but also prevent the smells of different products from mixing. Glass and ceramic dishes in this regard are preferable to plastic, which itself can absorb aromas.
To maintain freshness, you can keep special odor absorbers in the refrigerator. They are sold in hardware stores and work on the principle of a carbon filter. Change them according to the instructions, usually once every 2-3 months.
How often should you wash the refrigerator?
It is recommended to completely defrost and wash it every 3-4 months. However, if you notice a spilled liquid or a foreign odor, you need to do this immediately, without waiting for the planned date.
Can bleach be used for washing?
The use of chlorine-containing products is not recommended. They can damage plastic parts, cause them to yellow, and leave a lingering chemical odor that will be difficult to remove.
Why does your refrigerator smell like sewer?
Most often, this indicates a clog in the drainage system. Water containing food particles stagnates and rots. It is necessary to clean the drainage hole with a brush or soft wire.
Are ozonizers effective?
Yes, household ozonizers perfectly destroy bacteria and neutralize odors. However, they must be used strictly according to the instructions, since ozone in high concentrations is harmful to health.
