Occurrence A persistent unpleasant aroma in the refrigerator is not just discomfort, but also a signal of the growth of bacteria, which can be hazardous to health. Often the source of the problem is obvious: a spoiled product, spilled milk or a piece of cheese forgotten on the shelf, but sometimes the smell is absorbed into plastic walls and rubber seals, becoming a constant companion. Deep cleaning in this case, it becomes the only way to restore freshness.
Before Before taking active steps, it is necessary to understand the nature of the occurrence of “flavors”. The plastic with which the internal chambers of modern models are finished Liebherr or Boschhas a porous structure that can adsorb volatile substances. If not carried out in time deodorization, the smell can permeate even those products that initially did not have any foreign taste.
In this article we will analyze time-tested and professional methods for eliminating the problem. You will learn which products are truly effective and which can damage the equipment, and also receive a step-by-step algorithm for cleaning.
Preparing the equipment and finding the source of the problem
The first and most important step is to completely empty the refrigerator compartment. You can’t just spray the freshener on top of the food - this will only mask the problem for a short time, but will not solve it. You will need to completely remove all shelves, drawers and containers to gain access to all surfaces. Visual inspection will help identify obvious sources of contamination, such as traces of spilled liquids or food debris in hard-to-reach corners.
Particular attention should be paid to the condensate drainage system. In many models, the water drainage hole is located on the back wall, and this is where mucus and mold often accumulate, causing a musty smell. Cleaning this channel often solves the problem without the use of aggressive chemicals. Also check the condition of of the rubber seals on the door, as food debris is often hidden in the folds of the material.
⚠️ Attention: Before you start washing, be sure to disconnect the refrigerator from the power supply. Working with water and electrical appliances without following safety precautions can lead to a short circuit or electric shock.
For high-quality cleaning, you will need a basic set of tools and products. Do not use abrasive sponges, which can scratch the plastic, creating microcracks for bacterial growth in the future.

Effective folk remedies for removing odors
Folk methods often turn out to be more effective and safer than aggressive household chemicals, especially when it comes to food storage areas. One of the most powerful absorbents is activated carbon. It is able to absorb molecules of odorous substances without releasing anything in return. It is enough to crush 10-15 tablets and scatter the powder into containers, leaving them in the chamber for a day.
Acetic acid is another time-tested fighter against bacteria and odors. A solution of table vinegar and water in a 1:1 ratio perfectly disinfects surfaces and neutralizes unpleasant odors. After treating with vinegar, it is important to thoroughly ventilate the chamber, since the strong smell of acid is also undesirable for the products.
Baking soda acts as a mild abrasive and an excellent odor absorber. A paste of soda and water helps remove old stains, and dry soda left in an open container has a long-lasting effect. This remedy is especially effective against odors of fish or onions. odorant long-acting. This product is especially effective against fish or onion odors.
Natural odor absorbers, such as brown bread, rice or coffee beans, also show good results. They work slower than their chemical counterparts, but are absolutely safe and always at hand. Place these products in small bowls and place them on the shelves of an empty refrigerator for 2-3 days.
Step-by-step instructions for deep cleaning
The cleaning process should be systematic so as not to miss a single detail. Defrost the refrigerator first if the model requires manual defrosting, or simply wait for the ice to thaw in the No Frost system. Drain all the water and wipe the camera dry.
Removable elements - glass shelves and plastic drawers - are best washed in the bathtub or shower using a warm soapy solution. This will allow you to thoroughly process them on all sides and allow them to dry completely while you work on the interior of the case.
☑️ Deep cleaning checklist
Wipe the inner walls of the case with movements from top to bottom. Pay special attention to the corners and joints of the panels, where dirt accumulates most often. If the smell is very persistent, the washing procedure with the selected product (vinegar, soda, special product) may need to be repeated 2-3 times.
After wet cleaning, be sure to leave the refrigerator doors open for at least 2-4 hours for complete drying and ventilation. Turning on a wet appliance is unacceptable, as this can lead to the formation of new mold.
Cleaning the No Frost system and drainage hole
Owners of refrigerators with the system No Frost often forget that the evaporator and fan also need care. Although these elements are hidden behind plastic panels, odor can emanate from there through the air ducts. If after thoroughly washing the chamber the smell remains, perhaps the problem lies in the air circulation system.
The drainage hole is the “Achilles heel” of any refrigerator. A clogged drain leads to stagnant water, blooms and a putrid odor. To clean it, use a special soft brush or a piece of soft wire/insulating tape twisted into a bundle.
| Cleaning method | Tool | Efficiency | Risk of damage |
|---|---|---|---|
| Rinsing with a syringe | Medical syringe (20 ml) | Average | Minimum |
| Mechanical cleaning | Special brush | High | Low |
| Blowing | Rubber bulb | High | Minimum |
| Chemical washing | Citric acid solution | Maximum | Medium (for metal) |
For disinfection drainage, you can carefully pour a warm solution of citric acid or chlorhexidine into the hole. This will kill bacteria living in the condensate drain pipe. Be careful not to damage the thin walls of the plastic channel.
⚠️ Attention: Never use sharp metal objects (knitting needles, scissors) to clean the drainage hole. You can puncture the tube or damage the defrost heating element, which will lead to expensive repairs.
Eliminating odors from plastic and new materials
A freshly purchased refrigerator often has a specific technical smell of plastic and lubricants. This is normal for new appliances, but requires proper preparation before loading products for the first time. Ignoring this step may result in the products absorbing a “chemical” taste.
To eliminate the smell of new plastic, rinsing with a weak solution citric acid or water with the addition of mustard is ideal. Mustard not only removes odors, but also creates a light film of fat, which makes subsequent cleaning easier. After processing with a new device, you should let it stand with the door open for at least 24 hours.
Why does a new refrigerator smell?
The smell of new plastic is caused by the release of volatile organic compounds from the body materials and insulation. The compressor preservative lubricant may also smell if it got inside during assembly. Usually the smell disappears within 3-5 days of active use.
If the smell of plastic does not go away for a long time, this may indicate poor-quality materials or a violation of production technology. In such cases, the use of professional Western absorbers (sprays with enzymes) may be the only way out.
Professional products and odor absorbers
When traditional methods fail, the modern chemical industry comes to the rescue. There is a whole class of products designed specifically for refrigerators. They contain enzymes that break down organic residues and antibacterial components.
Spray neutralizers are popular, which do not mask the odor with fragrances, but destroy its source at the molecular level. Gel absorbers are also effective, which are placed on shelves and work for several months, gradually absorbing odors.

- 💊 Tablets with activated carbon in containers
- 💧 Gel balls with mineral fillers
- 🍋 Natural sachets with zeolite
When choosing a product, pay attention to the composition. For your refrigerator, it is better to choose products labeled “Food Safe” or “Safe for Food Contact” to eliminate the risk of chemical contamination of food.
⚠️ Attention: Do not use strongly scented dishwashing detergents or high concentrations of chlorine bleach to clean the interior of the refrigerator. Their vapors can be absorbed into rubber seals and transferred to products.
Prevention: how to maintain freshness for a long time
The best way to deal with odors is to prevent their occurrence. Following the rules of product placement and food storage will help keep your refrigerator clean for months. Always pack products, especially those that have a strong aroma (fish, smoked meats, spices), in airtight containers or cling film.
Regular inventory audit is another important point of prevention. Make it a habit to check the expiration dates and condition of products at the back of the shelves once a week. Even one forgotten cucumber can become a source of problems in a few days.
First In, First Out (FIFO) rule
When loading products, place new packages deep into the shelf and push old ones forward. This ensures that you use expiring products first, preventing them from spoiling.
Perform a preventative cleaning of the refrigerator every six months, even if there is no visible contamination. This will help remove invisible plaque of bacteria and a greasy film that accumulates on the walls over time.
Following these simple rules will allow you to enjoy only the pleasant aromas of fresh food and forget about the problem of an unpleasant odor in the refrigerator.
Is it possible to use a steam cleaner to clean the refrigerator?
Use A steam cleaner is possible, but with great caution. The high temperature of the steam can deform the thin plastic of the shelves or damage the rubber seals. In addition, excess moisture may enter electrical parts. It is recommended to use steam only to treat the inner walls of the chamber, avoiding direct contact with electronics and seals, and thoroughly dry the chamber after the procedure.
How often do you need to defrost the refrigerator for cleaning?
The frequency of defrosting depends on the type of refrigerator. Models with manual defrosting require this procedure every 3-6 months when the ice layer reaches 5 mm. Refrigerators with the system No Frost do not require defrosting to remove ice, but preventive washing with disconnection from the network is recommended 1-2 times a year for disinfection.
Is it safe to use an ozone generator (ozonizer) inside the refrigerator?
Using household ozonizers to eliminate odors in the refrigerator is effective, since ozone destroys molecules of odorous substances and kills bacteria. However, the procedure must be carried out strictly according to the instructions: the refrigerator must be empty, and food and people removed from the room while the device is operating, since high concentrations of ozone are harmful to breathing. After treatment, the chamber must be well ventilated.
What to do if the smell remains after cleaning?
If thorough washing does not help, the source of the smell may be hidden. Check the vents, the space behind the rear panel (if accessible), and the drainage system itself. In rare cases, the smell may come from a refrigerant leak (has a specific chemical smell) or from burnt wiring. In such cases, diagnostics by a specialist is necessary.
