An unpleasant smell in the refrigerator is a problem that almost everyone faces. It appears suddenly, penetrates food and spoils your appetite. The most common causes are spoiled food, poor ventilation or infrequent cleaning. But don’t rush to spend money on expensive cleaners: vinegar and soda these are affordable and safe products that will do the job just as well as professional ones.
Why these particular ingredients? Vinegar neutralizes bacteria, and baking soda absorbs odors. Together they form a powerful duo that not only eliminates odor, but also disinfects surfaces. In this article you will find step-by-step instructions, prevention tips and answers to frequently asked questions. And also a table comparing methods and warnings about possible errors.
Why does an unpleasant smell appear in the refrigerator?
Before you start cleaning, it is important to understand the root of the problem. There can be several sources of an unpleasant odor:
- 🍎 Spoiled food - even one rotting fruit or bag of sour milk can “smell” the entire refrigerator.
- 🧊 Forgotten food scraps - crumbs, sauces or fat on shelves and in drawers begin to decompose over time.
- 🔄 Poor air circulation - if the refrigerator is full of food or the ventilation holes are blocked, odors stagnate.
- 🦠 Bacteria and mold - a humid environment is ideal for their growth, especially in the door seal.
- 🧪 New refrigerator - sometimes "smell" plastic" comes from newly purchased equipment. This is normal and goes away after 1-2 weeks.
If the smell appears suddenly, first check the expiration dates of the products. Pay special attention to meat and dairy products —they deteriorate the fastest. Also inspect the rubber seal on the door: if it is dirty or damaged, this may be the source of the problem.
⚠️ Attention: If the smell is similar to rotten eggs or hydrogen sulfide, this may indicate a freon leak. In this case, immediately unplug the refrigerator and call a technician. Self-cleaning will not help here!
Preparing the refrigerator for cleaning: 5 mandatory steps
For cleaning to be effective, the refrigerator must be properly prepared. Neglecting this step can nullify all efforts.
- Unplug. This is not only safe, but will also allow the door to remain open without constant buzzing.
- Take out all the food. Check them for freshness - perhaps the source of the smell has already been found. Place the food in a cooler bag or in a cool place (in winter you can take it out to the balcony).
- Remove shelves and drawers. They need to be washed separately. If they are glass, be careful - do not place them on a cold surface immediately after washing to avoid cracks.
- Throw it away expired products. Even if the package of kefir has not yet swelled, but the expiration date has expired, throw it in the trash without pity.
- Ventilate the refrigerator. Leave the door open for 15-20 minutes. This will help remove some of the odors before you start cleaning.
If your refrigerator has a system No Frost, please note: it cannot be washed under running water. It is enough to wipe the surfaces with a damp cloth. For models with a drip system (Direct Cool), you can carefully wash the back wall, but without fanaticism - do not pour water into the drainage hole.
Method 1: Cleaning with vinegar - disinfection and neutralization of odors
Vinegar is a natural antiseptic. It kills up to 80% of bacteria and neutralizes even persistent odors, such as fish or onions. Suitable for cleaning only table vinegar 9% (not to be confused with vinegar essence!).
Instructions:
- Prepare the solution: mix vinegar with water in proportion
1:1. - Soak in the solution a soft rag or sponge and wipe all internal surfaces: walls, shelves, drawers. Do not use abrasive sponges - they scratch the plastic and leave microcracks in which bacteria later accumulate.
- Pay special attention to the rubber seal - it must be cleaned on both sides. To do this, you can use a toothbrush soaked in a vinegar solution.
- Leave the refrigerator open for 10-15 minutes for the vinegar to take effect.
- Wipe everything with a clean damp cloth, then wipe dry.
The vinegar solution will also help get rid of limescale on shelves. If the smell is very persistent (for example, from fish or garlic), you can increase the concentration of vinegar to 2:1 (2 parts vinegar to 1 part water), but not more - a strong solution can damage the plastic.

⚠️ Attention: Never mix vinegar with bleach or other chemicals! This causes the release of a toxic gas called chlorine, which is hazardous to health.
Method 2: Cleaning with baking soda - absorbs odors and is mildly abrasive
Soda (sodium bicarbonate) works differently than vinegar. It doesn't kill bacteria, but it perfectly absorbs odors and removes greasy stains. In addition, soda is a soft abrasive that will help clean off burnt or dried dirt without the risk of scratching the surface.
Methods of use:
- 🧽 Soda solution: 2-3 tbsp. spoons of soda per 1 liter of warm water. Wipe all surfaces, then rinse with clean water.
- 🧂 Soda paste: mix soda with water until the consistency of thick sour cream. Apply to heavily soiled areas (for example, sauce stains), leave for 5-10 minutes, then rinse.
- 📦 Soda absorber: after cleaning, put an open box of baking soda in the refrigerator - it will absorb new odors.
To enhance the effect, you can combine soda with vinegar, but do not mix them together (this will lead to a violent chemical reaction). First, wash the refrigerator with a soda solution, then wipe with vinegar - this way you will get a double effect: disinfection and absorption of odors.
| Method | Advantages | Disadvantages | Better suited for |
|---|---|---|---|
| Vinegar | Kills bacteria, neutralizes persistent odors | Pungent odor, can damage plastic in high concentrations | Disinfection, elimination of odors of fish, onions, meat |
| Soda | Absorbs odors, removes grease, safe for all surfaces | Does not kill bacteria, has a weaker effect on strong stains | General cleaning, removal of greasy stains, odor prevention |
| Vinegar + soda | Double effect: disinfection + odor absorption | Requires more time, you need to rinse surfaces after treatment | Complicated cases when one method does not help |
Method 3: Combined cleaning with vinegar and soda - a double blow to odors
If vinegar and soda alone do not work, try their combination. This method is suitable for persistent odors that cannot be removed by regular cleaning.
Step-by-step instructions:
- Prepare two solutions:
- Solution 1: 2 tbsp. spoons of soda per 1 liter of water.
- Solution 2: vinegar and water in proportion
1:1.
This method is especially effective if the odor has penetrated into the plastic or rubber seal. Do not use it more than once every 2-3 months - acetic acid can cause damage over time coating.
Method 4: Vinegar and soda for external cleaning of the refrigerator
The smell can come not only from the inside, but also from the outside - for example, from a dirty back wall or seal. Exterior cleaning is often overlooked, but it is no less important.
What to do:
- 🔌 Back wall: move the refrigerator away from the wall and vacuum the back grille. Then wipe it with a damp cloth with a vinegar solution (
1:1). This will improve heat transfer and prevent overheating. - 🚪 Sealant: wipe the gum with soda paste (soda + water), then with vinegar solution. This will remove mold and bacteria that often accumulate in folds.
- 🖥️ Control panel: use a soft cloth soaked in a weak soda solution. Do not pour water on the buttons!
If there are greasy stains on the case (for example, from fingers), they can be removed with soda paste. For stainless steel it is better to use special products so as not to damage the coating.
⚠️ Attention: When cleaning the back wall, do not touch the compressor and other electrical parts. If the refrigerator has a system No Frost, do not wash the ventilation holes inside - this may disrupt the operation of the system.
Method 5: Prevention of odors - how to keep freshness for a long time
The best way to deal with odors is to prevent them. Here are a few proven methods:
- ☑️ Regular cleaning: clean the refrigerator at least once a month. It is enough to wipe the shelves with a soda solution.
- 🥬 Proper storage of food: keep meat and fish in sealed containers, fruits and vegetables in special boxes.
- 🧊 Odor absorbers: use activated soda charcoal or special absorbers (for example, "BioFresh").
- 🌿 Natural flavorings: put a slice of lemon, a sprig of rosemary or coffee beans in the refrigerator - they will add a pleasant aroma.
- 📅 Controlling expiration dates: check food for freshness once a week. Use the rule
FIFO(First In, First Out) - first eat what lasts longer.
If your refrigerator has a function "Antibacterial coating" (for example, in models Samsung RB or LG InstaView), this does not mean that cleaning can be ignored. Such a coating only slows down the growth of bacteria, but does not completely remove dirt and odors.
What to do if the smell remains after cleaning?
If the smell does not disappear after cleaning with vinegar and soda, try the following steps:
1. Check the drainage hole - it may be clogged, which leads to stagnation of water and an unpleasant odor. Clean it with a cotton swab.
2. Inspect the seal for mold. If there is one, treat the gum with hydrogen peroxide (3%).
3. Place a bowl of activated carbon (5-6 tablets) in the refrigerator for 12 hours. It will absorb residual odors.
What not to do when cleaning. refrigerator
Some actions may not only not help, but also aggravate the problem. Here's what is strictly prohibited:
- 🧴 Use aggressive chemicals: bleach, ammonia or plumbing cleaners can damage the plastic and leave a toxic odor.
- 🔥 Wash with hot water: sharp temperature changes can cause cracks in glass shelves.
- ❄️ Place hot products: this leads to the formation of condensation and accelerated growth of bacteria.
- 🧽 Use metal sponges: they scratch the surface, and dirt and bacteria accumulate in microcrackslater.
- 🚫 Close the refrigerator immediately after cleaning: let it air for at least 15-20 minutes.
Also, do not use scented candles or air fresheners inside the refrigerator. They may add a temporary scent, but will not eliminate the cause of the smell. In addition, particles of wax or aerosol can get on the food.
FAQ: Answers to frequently asked questions
Can you use apple cider vinegar instead of table vinegar?
Yes, apple cider vinegar is suitable for cleaning the refrigerator, but it is less effective than table cider vinegar. It is 9% lower. acidity, so the disinfecting properties are weaker. If you still decide to use apple cider vinegar, take undiluted or increase the concentration of the solution to 2:1.
How long should you ventilate the refrigerator after cleaning with vinegar?
Minimum 15-20 minutes, but if the smell of vinegar is strong, you can leave it open for 30-40 minutes. To speed up the process, place a bowl of soda inside - it will neutralize the vinegar smell.
Will soda help if the smell comes from plastic containers?
Yes, but the containers need to be cleaned separately. Soak them in a soda solution (4 tablespoons per 1 liter of water) for 1-2 hours, then wash with detergent. remedy. If the smell remains, try wiping the containers with vinegar or placing them in the sun for several hours - ultraviolet light kills bacteria.
Is it possible to clean the refrigerator with soda and vinegar if there are food in it?
No, all food can be removed. Secondly, during cleaning you will move the shelves and. boxes, which can lead to food falling. If it is not possible to remove everything, at least remove perishable foods (meat, dairy, ready-made meals).
How often should you change the soda in the refrigerator if it is used as an odor absorber?
Soda in an open container should be changed every 1-2 months. If the smell appears earlier, replace it. immediately. To enhance the effect, you can add 2-3 drops of essential oil (lemon or lavender) to the soda, but do not overdo it - the strong aroma can be absorbed into the food.
