The appearance of an unpleasant aroma in the refrigerator compartment is a signal that cannot be ignored. The smell can be caused either by accidentally spilled milk or by the development of pathogenic microflora in hard-to-reach places. Ignoring the problem leads to the fact that an off-flavor is transmitted to the products, and their shelf life is reduced.
To effectively solve the problem, it is necessary to understand the nature of the contamination. Organic residues they decompose, releasing gases that are absorbed by plastic and rubber seals. Simple ventilation in such cases is not enough; deep cleaning is required using the right detergent compositions, which not only remove dirt, but also disinfect surfaces.
In this article we will analyze proven methods that allow you to return the device to perfect cleanliness. You will find out which household products really work, and which ones are better to avoid so as not to damage the internal coating of the chamber.
Causes of persistent odors in the refrigerator compartment
Before looking for how to wash the inside of the refrigerator so that there is no smell, it is important to identify the source of the problem. Most often, the culprits are expired products that may have gotten lost in the depths of the shelves. Also, the cause may be a malfunction of the condensate drainage system, where water and mucus accumulate.
The plastic from which the inner walls of modern models are made Liebherr or Boschhas a porous structure. It actively absorbs volatile substances. If you do not wash the shelves for a long time after storing fish or onions, the aroma can persist for months even after the source is removed.
Another hidden reason is clogging of the drainage hole. Water flowing down the back wall carries microparticles of food with it. If the drain is clogged, this mixture begins to rot, creating a persistent stench of dampness and mold. In such cases, not only washing is required, but also cleaning of the channel.
- 🦠 Reproduction of bacteria and mold in spilled liquids that got under the boxes.
- 🥩 Long-term storage of products with a strong aroma in open containers.
- 🧊 Violation of the tightness of the packaging of meat or fish products.
- 💧 Stagnation of water in the condensate tray or in the drainage system.
⚠️ Attention: If after thorough cleaning the smell appears again after a few days, check the technical condition of the device. It may be necessary to replace the seal or repair the No Frost system, as the problem may be inside the unit.
It is important to consider that different materials react to dirt differently. Glass shelves are easy to clean, but plastic containers for vegetables may require more aggressive but safe means to remove ingrained odors.
Preparing for washing: defrosting and removing parts
High-quality cleaning is impossible without proper preparation. The first step should always be to complete the defrosting device, even if it is equipped with a No Frost system. This is necessary in order to reach all corners and give the unit a rest before washing.
All removable elements - shelves, drawers, egg trays and bottle holders - must be removed. It is better to wash them separately in the bath or shower using warm water. This will avoid scratches on the inner walls of the chamber when carelessly handling heavy glass inside a narrow space.
☑️ Washing preparation plan
While the removable parts are drying, you can work on the body. Wipe the external surfaces to prevent dust from getting inside during the active washing phase. Make sure that there are no crumbs or small debris left in the chamber, which, if wet, will turn into mush and make cleaning difficult.
If you are the owner of a model with a fresh zone, pay special attention to its insulation. In some models Samsung and LG these zones have separate ventilation ducts, which can also accumulate odors.
Folk remedies for odor removal and disinfection
Many housewives prefer to use time-tested folk methods, as they are safe for health and do not contain aggressive chemicals. The leader among the funds is ordinary baking soda. It perfectly neutralizes acidic odors and works as a soft abrasive.
To prepare the solution, dilute 2 tablespoons of soda in a liter of warm water. Use this solution to wipe all surfaces. After treating with soda, the surfaces do not need to be thoroughly rinsed, since it is not toxic, but for perfect shine it is better to wipe with a clean damp cloth.
Another powerful tool is acetic acid. It kills bacteria and removes limescale that often forms on the back walls. However, vinegar has its own pungent odor, so after processing the chamber must be well ventilated.
Recipe for a powerful neutralizer
Mix 1 liter of warm water, 100 ml of table vinegar (9%) and 2 drops of lemon or tea tree essential oil. This mixture will not only wash away dirt, but also leave a fresh aroma, killing mold spores.
Hydrogen peroxide has also proven itself as an excellent remedy. It not only washes, but also whitens plastic, removing yellow stains from age or contact with certain products. It is enough to wipe the walls with a 3% solution.
- 🍋 Lemon juice is a natural antiseptic that leaves a pleasant citrus aroma.
- ☕ Ground coffee or activated carbon are used as odor absorbers after washing.
- 🧼 Laundry soap - effectively dissolves fat, but requires careful rinsing.
- 🌿 Ammonia - helps with very strong, ingrained odors, but requires caution.
Household chemicals: what can be used safely
If traditional methods do not seem effective enough, you can resort to industrial products. The main rule is that they should not contain chlorine or strong abrasives. Chlorine can damage plastic, and scratches will become a new refuge for bacteria.
Ideal for washing dishwashing gels. They foam well and rinse off easily. It is important to use them in small quantities so that you do not have to wash out the foam from cracks and seals for a long time.
There are special sprays for cleaning kitchen surfaces and refrigerators. They often contain antibacterial components. When choosing such a product, read the label: it should indicate that the composition is safe for contact with food.
| Product | Effectiveness against odor | Safe for plastic | Necessity rinsing |
|---|---|---|---|
| Soda solution | High | Absolutely safe | Desirable |
| Vinegar 9% | Very high | Safe | Required |
| Dish gel | Average | Safe | Required |
| Hydrogen peroxide | High | Safe | Not necessary |
| Specialized spray | High | Depends on the composition | According to instructions |
It is strictly not recommended to use solvents, acetone or gasoline. These substances can melt the plastic or make it cloudy and brittle. It is almost impossible to restore an inner box damaged in this way.
Technology for cleaning seals and hard-to-reach places
The rubber seal around the perimeter of the door is the place where black mold and dirt most often accumulate. It is often the smell of dampness that emanates. You need to wash it thoroughly, bending the folds with your fingers or using a soft toothbrush.
A cotton swab dipped in hydrogen peroxide or vinegar solution is ideal for cleaning folds. Movements must be careful so as not to damage the rubber. If there are already black spots of mold on the seal, they need to be processed several times until they disappear completely.
Don't forget about the drainage hole. It is located at the bottom of the rear wall of the refrigerator compartment. You can clean it using a special brush or soft wire wrapped in cotton wool. You can carefully pour a little soda solution into the hole for disinfection.
⚠️ Attention: Do not use sharp metal objects (knives, knitting needles) to clean the seal or drainage. You may accidentally pierce the water drainage channel or tear the rubber, which will lead to the door being sealed.
After cleaning all hard-to-reach places, be sure to wipe them with a dry cloth. The moist environment of closed rubber folds is an ideal incubator for bacteria. Dryness guarantees the absence of odor in the future.
Drying, ventilation and prevention
The final stage is proper drying. Do not turn on the device until it is completely dry. Remaining moisture will quickly cause a new odor to appear. The doors should be open for at least 2-3 hours, preferably a day.
To speed up the process, you can use a fan by directing the air flow inside the chamber. Through ventilation allows you to remove any remaining detergents and odors that could rise from the depths of the plastic.
To prevent the appearance of unpleasant odors, use odor absorbers. These can be special balls, sachets with coal or folk remedies, such as a saucer with soda, black bread or ground coffee.
Regular inspection of products is the best prevention. Try not to store opened food for longer than 2-3 days and always use airtight containers. This will keep not only the food fresh, but also the refrigerator itself.
Frequently asked questions (FAQ)
Is it possible to wash the inside of the refrigerator soap?
You can use regular toilet or laundry soap, but with caution. It leaves a film, which itself can become a source of odor when heated. If you choose soap, rinse it thoroughly with plenty of water and wipe the surface with a damp and then dry cloth.
How to remove odor after storing fish or meat?
To remove persistent fish odors, a solution of citric acid or vinegar is best suited. Wipe down all surfaces, including shelves and drawers. After this, place a plate with activated carbon or ground coffee on the shelf and close the door for several hours.
Is it safe to use a steam cleaner to clean the refrigerator?
Using a steam cleaner inside the chamber is not recommended. Sudden temperature changes and excess moisture can damage plastic elements, cause deformation or damage electronic sensors located behind the walls. It is better to use traditional liquid products.
Why does the refrigerator smell if it is clean?
If it is visually clean, but there is an odor, the source may be hidden in the drainage system, under the casing (if liquid has gotten there) or in the door seal. Also, the smell can come from an old product forgotten in a corner or a liquid that was once spilled and absorbed into the plastic.
