An unpleasant aroma emanating from the refrigerator compartment can ruin the mood of any home cook and, more importantly, spoil the taste of cooked dishes. The appearance of foreign odors often indicates the growth of bacteria, mold, or the ingestion of spoiled food that may have leaked. To effectively solve this problem, it is not enough to simply wipe the shelves with a damp cloth - an integrated approach to cleaning is required.
In this article we will analyze proven methods that will help not only eliminate, but also prevent the reappearance of odor. You will learn which natural remedies safe for food containers, how to properly defrost and what mistakes are most often made when caring for the internal surface of the unit.
Before taking active steps, it is important to understand the nature of the odor. The most common sources are vegetables forgotten in the depths of drawers, spilled milk or meat, or a clogged drainage hole. Ignoring these factors can lead to odor being absorbed into plastic parts and rubber seals, making them impossible to use without replacement.
Preparation for general cleaning
The beginning of the cleaning process requires careful preparation, on which half the success depends. The first and most important step is to completely disconnect the device from the power supply. This is necessary not only for safety, but also to allow the refrigerator to defrost naturally if the model is not equipped with a No Frost system.
While the unit is turned off, it is necessary to remove all contents. Conduct an audit of your products: ruthlessly throw away anything that raises the slightest doubt about its freshness. Even if a product looks fine, but has a strange taste or smell, it belongs in the trash bin, not on the shelf. It is better to temporarily transfer all remaining supplies into a thermal bag or a bowl of ice so that they do not spoil during cleaning.
The next stage is dismantling the removable elements. Shelves, vegetable drawers, door containers and egg holders need to be removed. It is more convenient to wash plastic and glass parts separately in the bathtub or under a shower head using warm water and a mild detergent. Please note that glass shelves cannot be washed with hot water immediately after removal from the freezer - the glass may burst due to temperature changes.
⚠️ Attention: Do not use sharp objects (knives, screwdrivers) to scrape off ice or frozen fat. Damage to the internal coating of the chamber or evaporator will lead to refrigerant leakage and costly repairs.
Pay special attention to the rubber seals on the door. It is in the folds of corrugated rubber that mold and dirt most often accumulate, which are the source of the musty smell. Carefully bend the edges of the seal and wipe them with a cotton swab dipped in the cleaning solution.
Effective folk remedies for eliminating odor
Household chemicals are not always safe for food storage areas, so many prefer to use time-tested folk methods. They are effective, safe and, as a rule, always on hand. The main advantage of such products is the absence of toxic fumes that could subsequently be absorbed into products.
The leader among natural absorbents and disinfectants is baking soda. It perfectly neutralizes acidic odors and gently abrades dirt. To prepare the solution, dilute 2 tablespoons of baking soda in a liter of warm water. This solution can be used to wipe any surface, including plastic and metal. After treating with soda, the surface does not require thorough rinsing; it is enough to wipe it with a clean damp cloth.
Acetic acid has also proven itself as a powerful agent against bacteria and mold. Table vinegar (9%) is diluted with water in a 1:1 ratio. The pungent smell of vinegar quickly dissipates, taking other aromas with it. However, you should be careful with acids if you have a refrigerator with parts made of natural stone or certain types of plastic, although in modern models Samsung or LG plastic is usually resistant.
Citric acid or fresh lemon juice will give the chamber a pleasant, fresh aroma. This product is best used at the final stage, when the main contaminants have already been removed. Citric acid also helps remove the yellow coating that often forms on white plastic from time and grease.
- 🍋 Lemon juice: Ideal for final processing and adding freshness, but does not disinfect well.
- 🧼 Laundry soap: Copes well with greasy deposits, but requires very careful rinsing.
- 🦷 Toothpaste: An unusual but effective means for cleaning hard-to-reach places and removing stubborn stains.
- 🌿 Ammonia: A powerful remedy against mold and mustiness, but requires work in in a ventilated area.
Comparison of industrial products and their safety
If traditional methods do not seem effective enough to you or you prefer ready-made solutions, the market offers a wide range of specialized sprays and foams. However, when choosing household chemicals for the refrigerator, you need to be extremely attentive to the composition.
Many universal cleaners contain chlorine or aggressive surfactants, which can be dangerous when in contact with food. Even after thorough rinsing, microscopic chemical particles can remain in the pores of the plastic. Therefore, experts recommend choosing products marked “eco”, “biodegradable” or specially designed for washing refrigerators and children’s dishes.
The table below provides a comparison of popular types of cleaning products so that you can choose the best option for your situation:
| Type of product | Effectiveness against odor | Safety | Best use |
|---|---|---|---|
| Soda solution | Average | Absolutely safe | Weekly cleaning, fresh pollution |
| Acetic acid | High | Safe after ventilation | Mold removal, disinfection |
| Special. sprays for refrigerators | Very high | Requires rinsing | General cleaning, old stains |
| Chlorine-containing products | Maximum | Hazardous for food areas | Only external parts and seals |
When using industrial sprays, it is important to follow the instructions on the packaging. Usually you need to apply foam, wait a few minutes and rinse thoroughly with plenty of water. Do not forget that chemicals can destroy some types of plastic with prolonged contact.
Step-by-step instructions: how to wash properly
The washing process should be systematic. Chaotic wiping of surfaces often leads to dirt simply being smeared throughout the chamber. Start on the top shelf and work your way down. It's a rule of physics: dirty water and dust particles will flow down, and you'll wash them off at the very end.
Thoroughly rinse all corners of the camera, paying special attention to the back wall. This is where sources of unpleasant odors are most often hidden. If you find dried-on stains, do not scrub them as hard as you can with a dry cloth. Apply a cloth soaked in the cleaning solution to the stain for 5-10 minutes. The dirt will get wet and be removed with a slight movement.
☑️ Checklist for perfect cleaning
The drainage hole, usually located on the back wall of the refrigerator compartment, requires special attention. It is designed to drain condensate. If it becomes clogged with crumbs or mucus, water will begin to accumulate at the bottom, creating an ideal environment for bacteria and a rotten water smell. You can clean it using a special brush or soft wire wrapped in cotton wool.
After wet cleaning, be sure to wipe all surfaces dry with a clean microfiber cloth. Residual moisture may cause mold growth in the future. Let the refrigerator stand open for at least 30-60 minutes so that all hard-to-reach places dry out and the odors of cleaning products disappear.
⚠️ Attention: In different refrigerator models, the location of drainage and removable shelves may differ. We recommend checking the manufacturer's instructions (
User Manual) before dismantling complex structures so as not to damage the fastenings.
What to do if the smell remains after cleaning?
If the smell persists after thorough washing, it may have penetrated into the polyurethane foam insulation of the body (this happens when a large amount of liquid gets inside through drainage or cracks). In this case, special odor absorbers with activated carbon or ozonizers will help. In extreme cases, you will need to call a technician to replace the seal or insulation.
How to eliminate the smell after defrosting or purchasing
The smell of a new refrigerator is the “aroma” of fresh plastic and factory grease. It is not dangerous, but can be transferred to foods, especially those with a porous structure, such as butter or cheese. To get rid of it, it is not enough to simply wipe the new unit. After installing and removing all shipping films, rinse the chamber with a weak solution of soda and leave the doors open for a day.
The odor situation after defrosting is often associated with residual water or forgotten products that were placed during long-term defrosting. If you defrosted the refrigerator incorrectly (for example, using a hairdryer or hot water), you might get a smell of burning plastic or glue. In this case, only long-term ventilation and treatment with activated carbon will help.
To eliminate persistent “odors” after defrosting, use adsorbents. Activated carbon, silica gel or special absorbent balls are placed on shelves for 2-3 days. Coal can be crushed into powder and poured into small saucers - the absorption area will increase significantly.
- ☕ Ground coffee: It absorbs odors perfectly, but can itself transfer its aroma to products.
- 🍞 Black bread: Cut into pieces, it works as a natural filter (our method grandmothers).
- 🧂 Salt: In an open container, it absorbs moisture and odors well.
- 🍚 Rice: Raw rice in a bowl works similarly to silica gel.
Prevention: how to maintain freshness for a long time
So that the question “how to clean the inside of the refrigerator from the smell” does not arise before you every two weeks, it is important to follow the operating rules. The main reason for the appearance of amber is the storage of products in open containers. Liquid and strong-smelling foods (fish, smoked meats, open canned food) should be stored only in closed containers or under cling film.
Regularity is the key to success. Don't wait for a deep cleaning once a year. It’s enough to do a quick inspection once a week and wipe down the shelves if something spills on them. Once a month, it is recommended to wash shelves and drawers with warm water and a mild detergent.
Keep an eye on the expiration date. Get into the habit of putting new products at the back of the shelf and pushing old ones forward. This stock rotation rule will help you avoid a situation where you find a month-old jar of fermented sauce in the far corner.
Also, do not forget about the temperature. If the refrigerator is too warm, food will spoil faster. Check the thermostat settings. For the main chamber, the optimal temperature is from +2 to +5 °C, for the freezer - -18 °C and below.
Is it possible to wash the refrigerator with soap?
You can use ordinary toilet or laundry soap, but with caution. It leaves a film that is difficult to remove and can transfer odors to products. It is better to use special products or soda. If you use soap, rinse it thoroughly with plenty of water.
How often should you wash the refrigerator?
General cleaning with defrosting (if required) is recommended once every 3-4 months. Wet wiping of shelves and checking products should be done weekly. If contamination occurs (milk spilled, meat falls), you need to clean it up immediately.
How to remove the smell of fish from the refrigerator?
The fish smell is very persistent. A vinegar solution (1:1 with water) will work best for wiping all surfaces, including seals. After this, place activated carbon or lemon zest on the shelves for a couple of days.
Why does the refrigerator smell like sewage?
Most likely, the drainage hole is clogged, and water with bacteria stagnates inside the system. It is necessary to clean the drainage with a special brush or soft wire, and then rinse the system with warm water and soda.
