The refrigerator is one of the most important units in the kitchen, keeping food fresh and ensuring food safety. However, the inner surface of the camera, made of plastic, is regularly exposed to moisture, grease, acids and foreign odors, which over time leads to the formation of persistent contaminants. Many housewives are faced with a problem when a regular soap solution no longer copes with sticky residue or stubborn stains, requiring more drastic measures.
Incorrectly selected chemistry can not only fail to remove dirt, but also damage the structure of the polymer, making it dull or even causing the appearance of microcracks in which bacteria will multiply at double the speed. In this article, we will look in detail at what products are really effective for different types of stains, how to safely bleach yellowed plastic, and what tools are best to use so as not to scratch the glossy surface.
High-quality care for the inner chamber is not only an aesthetic issue, but also a matter of hygiene, because old grease and mold can become a source of an unpleasant odor, which is subsequently absorbed into fresh food. We will consider both time-tested folk methods and professional household chemicals so that you can choose the best option for your refrigerator model.
Preparing for general cleaning of the chamber
Before taking active steps to remove difficult stains, it is necessary to properly prepare the work area and free up space for maneuver. The first step is always to completely disconnect the unit from the power supply, which will protect you from electric shock if moisture gets on the electrical contacts or the compressor. After this, you should remove all the products, putting them in thermal bags or pots with cold water so that they do not spoil during a long procedure.
Particular attention should be paid to removable elements: it is better to remove the shelves, drawers for vegetables and containers on the door separately and wash them under running water using standard detergents. This will allow you to access hard-to-reach areas, such as shelf rails and cabinet corners, where mold and dirt are most likely to accumulate. Don’t forget to also defrost the freezer if your model does not have a No Frost system, since the ice crust will interfere with proper cleaning of the walls.
To work, you will need a basic set of tools, which can be found in every home, but its effectiveness directly depends on the correct application. Use soft sponges, microfiber or special viscose cloths that absorb moisture well and do not leave lint on the surface.
⚠️ Attention: It is strictly forbidden to use metal brushes, scrapers or abrasive powders, as they leave micro-scratches on the plastic, into which dirt will subsequently become clogged, making the surface rough and dark.
After all the preparatory steps have been completed, you can proceed to choosing the cleaning product that will be most effective in your specific situation. It is important to understand that there is no universal solution for all types of contamination, so the approach must be comprehensive.
Folk remedies for removing fat and plaque
Home recipes are often more effective than aggressive chemicals, especially when it comes to food contamination, which should be completely safe for contact with food. One of the most accessible and effective means is baking soda, which works as a mild abrasive and an excellent odor adsorbent. To prepare a cleaning paste, you need to mix soda with a small amount of warm water to the consistency of thick sour cream, apply this mixture to contaminated areas and leave for 15-20 minutes.
After the paste dries, it is easily removed with a damp cloth, taking with it fatty deposits and plaque. Another powerful tool in the fight for cleanliness is table vinegar, which, thanks to its acidic environment, perfectly breaks down limescale and disinfects the surface. Vinegar solution and water in a 1:1 ratio can be poured into a spray bottle and treated all the internal walls, paying special attention to the places where the shelves are attached.
If you are worried not only about fat, but also about persistent odors, ammonia will come to the rescue, which must be used with caution due to the pungent odor. Wiping the plastic with a solution of ammonia (1 tablespoon per liter of water) restores shine and removes fingerprints, but after the procedure the camera must be thoroughly ventilated. For delicate surfaces, such as glossy plastic in modern models Samsung or LG, laundry soap, grated and dissolved in hot water, is excellent.
- 🧼 Baking soda is an ideal abrasive for removing dried-on stains without scratches.
- 🍋 Citric acid or juice - perfectly dissolves fat and leaves a pleasant aroma.
- 🥔 Half a raw potato - helps remove light dirt and polishes plastic.
- 🍺 Dark beer is an unusual but effective means for washing glass and glossy plastic.
The use of natural ingredients allows you to avoid toxic substances getting into food, which is especially important for families with small children. However, it is worth remembering that folk remedies may require more frequent repetition of the procedure compared to professional chemistry.
Professional household chemicals for plastic
When contaminants wear persistent nature or it is necessary to carry out disinfection after storing spoiled products, specialized cleaning products developed by manufacturers of household appliances come to the rescue. The market offers a wide range of sprays, gels and foams that do not require rinsing or can be easily removed with water without leaving streaks. When choosing a product, it is important to pay attention to the labeling “for refrigerators” or “for food plastic”, which guarantees the safety of the composition.
Foam products are popular, which are applied to vertical surfaces, flow down and effectively dissolve fat in hard-to-reach places. Active components in such formulations, such as surfactants and enzymes, break down organic contaminants at the molecular level. Spray cleaners often contain antibacterial additives that create a protective film that prevents the growth of microbes for several days after cleaning.
When using chemicals, you must strictly follow the instructions on the packaging, especially regarding exposure time - overexposing the product can lead to clouding of the plastic or the appearance of stickiness. It is also not recommended to mix different cleaning products, as this can lead to an unpredictable chemical reaction and the release of harmful fumes. For models with antibacterial coating, such as some series Bosch or Whirlpool, it is better to choose the softest gels without chlorine and aggressive solvents.
⚠️ Attention: Avoid using products containing chlorine, acetone or gasoline, as they can react with polymers, causing deformation or a change in the color of the internal coating of the chamber.
After chemical treatment, you must thoroughly wipe the surfaces several times with a clean, damp cloth to remove any remaining detergent. This will prevent chemicals from getting on the food and eliminate the appearance of foreign taste in stored food.
Is it possible to wash the refrigerator with dishwashing detergent?
Yes, you can, but only if it is completely washed off with water. Dish gels often contain fragrances and humectants that can leave a sticky film that attracts dust. If you use dish gel, be sure to add a little vinegar to the rinse water to neutralize the soap residue.
How to remove yellowness and return whiteness
Over time, the white plastic in the refrigerator may lose its original color and acquire an unpleasant yellowish tint, which is especially noticeable on older models. The main reasons for this process are oxidation of the material under the influence of air, ultraviolet radiation and the effects of fatty fumes that penetrate the polymer structure. You can restore snowy whiteness using hydrogen peroxide, which is an effective bleach and does not leave toxic traces.
To achieve a visible result, you need to generously moisten a sponge or cotton pad with a 3% peroxide solution and thoroughly wipe the yellowed areas, leaving the product on the surface for 10-15 minutes. If the yellowness is strong, you can use a more concentrated solution of hydrogen peroxide (up to 8-12%), which is sold in hairdressing stores, but you need to work with it only with rubber gloves. Another effective method involves using a paste made from baking soda and lemon juice, which not only whitens but also deodorizes the surface.
In some cases, when the yellowness is not caused by pollution, but by a change in the chemical structure of the plastic due to aging, mechanical cleaning may not help. In such situations, you can try using special wipes for office equipment or plastic restoration sprays that contain components that mask yellowness. However, it is important to understand that if the plastic has become brittle and crumbles, this indicates deep degradation of the material, and cleaning will not return it to its original properties.
| Agent | Concentration | Exposure time | Efficiency |
|---|---|---|---|
| Hydrogen peroxide | 3-12% | 15-30 min | High |
| Soda + Lemon | Paste 1:1 | 20 min | Medium |
| Wipes for screens | Ready solution | No rinse | Low/Medium |
| Chlorine-containing (caution) | Diluted | 5 min | High (risk of damage) |
Regular preventive cleaning helps prevent the appearance of yellowness, since the fatty film deposited on the walls oxidizes over time and changes color. Therefore, it is recommended to wipe the fridge compartment with a solution of vinegar or soda at least once a month.
Removing traces of tape, glue and marker
When transporting or after purchasing new equipment at Plastic surfaces often leave traces of protective film, tape or labels that are difficult to remove with regular washing. The sticky adhesive layer can be effectively removed using vegetable oil, which is applied to a cotton pad and left on the stain for several minutes. The oil softens the glue, after which it is easily wiped off with a soft cloth, and any remaining grease is removed with dishwashing detergent.
An alcohol-containing liquid such as vodka, cologne or a special glass cleaner is excellent for removing marks from markers, felt-tip pens or stickers. Isopropyl alcohol is the safest solvent for plastic, as it evaporates quickly and leaves no residue, unlike acetone, which can melt the top layer of the polymer. If you don’t have alcohol on hand, you can try using a regular pencil eraser, which mechanically rolls off dirt without damaging the surface.
If there are traces of tape on the plastic that are not amenable to oil, you can use a hairdryer. Heating the adhesive layer with hot air makes it more elastic and makes it easy to remove the remaining tape, after which the surface is wiped with alcohol. It is important not to overheat the plastic, holding the hair dryer at a distance of at least 15-20 cm to avoid deformation.
- 🌻 Vegetable oil - dissolves glue from labels and tape.
- 🍷 Alcohol or vodka - removes traces of markers and ink.
- 🧽 Eraser - mechanically removes sticky marks without chemicals.
- 💨 Hair dryer - softens old glue for easy removal.
After removing stains, be sure to degrease the treated area so that dust and new dirt do not stick to it. Clean and smooth plastic is less susceptible to contamination in the future.

Fighting mold and unpleasant odors
The appearance of mold in refrigerator - this is a signal of high humidity and insufficient ventilation, which often happens when storing spoiled food or rarely ventilating the chamber. Mold not only spoils the appearance, but also releases spores that can settle on products and cause allergies or poisoning. To combat mold, it is necessary to use strong antiseptics, such as a solution of laundry soap, hydrogen peroxide or special antibacterial sprays.
Particular attention should be paid to the rubber seals on the door, since it is in the folds of rubber that black mold most often settles. Rubber cleaning should be done very delicately, using a cotton swab dipped in vinegar or peroxide, so as not to damage the elasticity of the material. After treating with an antiseptic, the refrigerator must be left open for several hours to completely dry and ventilate.
If the unpleasant odor persists after cleaning, this means that mold spores or the odor have been absorbed into hard-to-reach places or ventilation ducts. In this case, natural odor absorbers will help, such as activated carbon, ground coffee, soda in an open container, or special flavors for refrigerators. These absorbents need to be changed every 2-3 weeks until the odor completely disappears.
⚠️ Attention: If mold has affected large areas or penetrated under plastic panels, it may be necessary to disassemble the internal lining of the refrigerator, which is best entrusted to professionals so as not to break the seal of the chamber.
Regular inspection of products and timely Cleaning up spills is the best way to prevent mold and odors. Do not store expired products in the chamber.
What to do if the smell remains after cleaning?
Try putting a bag of rice or silica gel in the refrigerator, which perfectly absorb moisture - the cause of the smell. You can also wipe the walls with a pale pink solution of potassium permanganate, which kills bacteria.
Drying rules and contamination prevention
The final and one of the most important stages of cleaning is the proper drying of all surfaces, since the remaining moisture can become an ideal environment for the proliferation of bacteria and the appearance of mold. After wet cleaning, be sure to wipe all walls, shelves and drawers dry with a clean cotton cloth or paper towels. Pay special attention to the corners of the chamber and the joints of parts where water can stagnate.
In order to keep the refrigerator clean longer, it is recommended to use special mats for the shelves or cover them with cling film/paper towels, which are easy to replace if dirty. This will protect the plastic from scratches and absorption of colored stains from berries or sauces. It is also useful to carry out express cleaning regularly, at least once a week, by wiping the surfaces with a damp cloth to prevent the accumulation of grease.
Following food storage rules, such as using airtight containers and lids, will greatly simplify the maintenance of the refrigerator and extend the life of the plastic elements. Opened products not only spoil faster, but also contribute to the spread of odors and contaminants throughout the chamber.
- 🌬️ Leave the door open for 1-2 hours after cleaning to completely evaporate moisture.
- 📦 Use containers with lids for all liquid and odorous products.
- 🧴 Once a month, wipe the plastic with a vinegar solution to disinfect.
- 🚫 Do not put hot food in the refrigerator to avoid condensation.
By following these simple recommendations, you can keep the white and shiny appearance of the plastic of your refrigerator for many years, ensuring cleanliness and safety for everyone family.
Is it possible to wash the plastic of the refrigerator with chlorine-containing products?
Use chlorine (for example, “Belizna” or “Domestos”) to wash the internal plastic of the refrigerator highly not recommended. Chlorine is an aggressive oxidizing agent that can damage the structure of the polymer, make it brittle and cause yellow stains that cannot be removed. In addition, chlorine residues can react with food, which is hazardous to health. If disinfection with chlorine is necessary (for example, after storing meat with salmonella), use the minimum concentration, thoroughly rinse the product with plenty of water and ventilate the chamber for a long time.
How to clean the refrigerator if an egg has broken in it and dried out?
Dried whites and yolks can be removed by soaking the dirt. Soak a rag or sponge in warm soapy water and apply to the stain for 10-15 minutes. The white will soften and come off easily. To disinfect after removing an egg, wipe the area with a weak solution of vinegar or hydrogen peroxide, as a raw egg may contain salmonella.
Why does the plastic in the refrigerator become sticky and how to fix it?
Sticky plastic is usually caused by oxidation of fatty deposits or the destruction of the top layer of plastic under the influence of incorrect cleaning products (solvents, oils). If it is grease, a thorough wash with hot water and dishwashing detergent and then wiping with alcohol will help. If the plastic itself has degraded (becomes sticky and rough), it is difficult to restore it; You can try treating the surface with silicone grease for food production, but in some cases, replacement of the internal panels is required.
How often should you wash the inside of the refrigerator?
It is recommended to carry out general cleaning of the refrigerator by removing all products and washing the shelves once every 3-4 months. However, preventive wiping of shelves and removal of spilled liquids should be carried out immediately upon detection. Once a month, it is useful to wipe the chamber with a solution of vinegar or soda to disinfect and eliminate odors.
