Over the years, even the most reliable refrigerator loses its original appearance, and the main problem is the appearance of a persistent yellow coating on the inner walls. This plaque is not just an aesthetic defect, but the result of plastic oxidation under the influence of light, temperature changes and organic decay products. Ignoring the problem can lead to the fact that food grade plastic becomes porous and begins to absorb odors even more actively.
Before taking radical measures, it is necessary to understand the nature of the contamination. Yellowness often appears due to chemical reactions in the structure of the housing material itself, especially if the unit is placed in the sun or next to heating devices. However, in 90% of cases, the reason lies in fatty deposits and microparticles of food that have accumulated on the surface for years.
To effectively combat stains, you will need not only the right chemistry, but also patience. Cleaning the refrigerator - the process is delicate, since aggressive solvents can damage seals or make the plastic brittle. In this article, we will analyze proven methods that will help return equipment to a neat appearance without the risk of damage.
Preparing for general cleaning
Any serious work begins with preparation, and caring for household appliances is no exception. Before applying any products, it is necessary to completely empty the chamber of products and remove all shelves, drawers and containers. It is better to wash these removable elements separately in the bathroom or under the shower head, using warm water and standard dishwashing detergent.
Pay special attention to defrosting if your unit is not equipped with a system No Frost. The ice crust will interfere with access to the walls, and the water formed during melting can dilute the cleaning products, reducing their effectiveness. After defrosting, be sure to wipe the inside dry with a soft cloth.
It is important to provide access to all corners of the chamber. To do this, it is often necessary to remove plastic shelf guides and even the shelves themselves, if the design allows them to be safely removed. Do not forget to disconnect the device from the power supply to avoid a short circuit if moisture accidentally gets on the electrical contacts or the lighting lamp.
☑️ Preparing the refrigerator for washing
Folk remedies against yellowness on plastic
Home recipes are often more effective than aggressive chemicals, especially when it comes to old stains. One of the most powerful remedies is a mixture of hydrogen peroxide and baking soda. Peroxide acts as a mild bleach, oxidizing the yellow pigment, and soda works as a delicate abrasive, removing grease film.
To prepare the paste, mix hydrogen peroxide (3%) with soda until the consistency of thick sour cream. Apply the resulting mixture to the yellow areas and leave for 30-40 minutes. After this, rinse thoroughly with warm water. This method is especially good for white plastic, as it does not leave streaks and is safe for food surfaces.
Another proven remedy is acetic acid in combination with lemon juice. The acidic environment perfectly breaks down fatty deposits and neutralizes unpleasant odors. Soak a sponge in a solution of table vinegar (9%) and thoroughly wipe the walls. Lemon juice will enhance the effect and leave a pleasant fresh aroma, masking the smell of the old device.
If the yellowness is deeply ingrained, you can try the “compress” method. The cloth is generously moistened in a cleaning solution (for example, a mixture of ammonia and water in a ratio of 1:10) and applied to the problem area for several hours. Ammonia effectively dissolves organic contaminants, but requires good ventilation of the room due to the pungent odor.
Professional chemicals and special cleaners
When traditional methods fail, household chemicals designed specifically for plastic come to the rescue. Specialized sprays for cleaning refrigerators contain surfactants that not only wash away dirt, but also create a protective film that prevents the adhesion of new dirt.
When choosing a product, pay attention to the label “for food surfaces” or “food safe”. This ensures that the components of the drug are non-toxic and will not emit harmful fumes at low temperatures. Avoid products containing high concentrations of chlorine, as they can destroy the structure of the plastic, making it brittle.
Melamine sponges have proven themselves to be excellent. This is a modern material that works like an eraser: when rubbed, microfibers remove the thinnest layer of dirt without requiring additional chemicals. However, they should be used with caution on glossy surfaces so as not to leave matte scuffs.

- ✨ Melamine sponges - mechanically remove plaque without chemicals.
- 🌿 Biodegradable gels - safe for the environment and health.
- 🛡️ Plastic polishes - hide micro-scratches and restore color.
Odor removal: combating the source
Yellowness often goes hand in hand with a musty odor, which can persist even after a thorough wash. The reason lies in the porous structure of old plastic, which has absorbed odor molecules over many years of use. To eliminate aroma, it is not enough to simply wash the walls - adsorption is needed.
The simplest and most affordable way is to use activated carbon. The tablets should be crushed into powder, scattered into saucers and left in a closed refrigerator for a day. Coal has a huge surface area and is excellent at absorbing volatile compounds. Instead of coal, you can use silica gel or special odor-absorbing balls.
If rubber door seals emit odor, they need to be treated separately. Rubber is a capricious material, and aggressive chemicals can cause it to dry out. Wipe the seals with a solution of soda or a weak solution of vinegar, and then lubricate them with silicone grease to restore elasticity.
⚠️ Attention: Never use acetone, gasoline, or high-concentration alcohol-based solvents to clean rubber seals. These substances destroy the structure of the rubber, making it hard and brittle, which will lead to depressurization of the chamber.
To consolidate the result after cleaning, you can wipe the inner walls with a weak solution of essential oil (for example, lemon or mint). The main thing is not to overdo it so that the products do not acquire an off-flavor. Oils have antibacterial properties and prevent the development of mold in hard-to-reach places.
Table: Comparison of cleaning methods
To make it easier for you to choose the appropriate method, we have systematized the main methods according to their effectiveness and safety. Different types of dirt require a different approach: it is better to remove grease with alkali, and mineral deposits with acid.
| Method | Effectiveness against yellowness | Safety for plastic | Odor elimination |
|---|---|---|---|
| Peroxide + Soda | High | Safe | Average |
| Acetic acid | Medium | Safe | High |
| Melamine sponge | Very high | Risk of scratches | Low |
| Special. sprays | High | Depends on the composition | Average |
| Ammonia | High | Caution with rubber | High |
As can be seen from the table, a combined approach often gives the best result. For example, first treat the walls with peroxide to remove color, and then wipe with vinegar to eliminate odor.
Features of cleaning different types of surfaces
The interior space of the refrigerator is heterogeneous: there are smooth plastic, rough surfaces, metal and glass. Each material dictates its own rules of care. Smooth plastic is the easiest to clean, but scratches are more visible on it, so abrasives must be used carefully.
Metal back walls (on some models) or stainless steel shelves require the use of chloride-free products to avoid corrosion. Special polishes for stainless steel or regular alcohol are ideal for them, which evaporates quickly and leaves no traces.
Glass shelves can be washed with almost any window cleaner, but avoid sudden temperature changes. Do not put cold glass under hot water - it may crack. Also check the integrity of the glass: if there are chips, wash them with extreme care to avoid injury.
Can a steam generator be used?
The use of a steam generator is only permissible for metal surfaces and glass. It is strictly forbidden to direct a stream of hot steam at the plastic body or, especially, at the rubber seals - the plastic can be deformed and the rubber will lose elasticity.
The ventilation holes in the back wall of the chamber deserve special attention. Dust and fluff often accumulate there, which can become a source of odor and cause air circulation problems. It is better to clean them with a soft brush or vacuum cleaner at minimum power, trying not to damage the fragile plastic ribs.
Preventing the appearance of yellowness and odors
After successful cleaning, you want the result to last as long as possible. The main reason for the rapid appearance of yellowness and odors is improper storage of food. Always pack food in airtight containers or plastic wrap. Opened food not only smells, but also releases moisture and grease, which settle on the walls.
Regular cleaning is the key to cleanliness. It is enough to wipe the shelves with a damp cloth once a month to remove fresh dirt before it becomes embedded in the structure of the material. Once every six months, it is recommended to carry out a general cleaning with disassembly of all elements.
It is also important to monitor the serviceability of the condensate drainage system. If the drain hole is clogged, water accumulates at the bottom, creating an ideal environment for bacteria to grow and mold to develop, which stains the plastic. Clean the hole with a special brush or cotton swab as needed.
⚠️ Attention: If yellowness appears suddenly and is accompanied by a sticky coating, this may be a sign of plastic degradation due to age or exposure to ultraviolet radiation. In this case, mechanical cleaning can only worsen the condition - the plastic will begin to crumble. Consider replacing the internal panels or purchasing a new refrigerator.
Following these simple rules will allow your refrigerator to data-i="133">stay clean and fresh for many years. Remember that caring for equipment is an investment in the health of your family, because cleanliness inside the chamber directly affects the quality and safety of stored products. refrigerator stay clean and fresh for many years.

Is it possible to use acetone to remove yellowness?
Using pure acetone is highly not recommended. It is a strong solvent and can damage the structure of the plastic, making it cloudy or sticky. In addition, acetone vapors are toxic and can take a long time to evaporate from the chamber, which is dangerous for products.
Why does the plastic in a new refrigerator turn yellow?
If a new refrigerator turns yellow, this may be a consequence of a manufacturing defect in the plastic or the use of low-quality fire retardants. Also, the cause may be direct sunlight or proximity to heat sources, which triggers the oxidation process.
How often should you wash the inside of the refrigerator?
It is recommended to carry out light wet cleaning once a month. General cleaning with defrosting and washing of all removable elements should be done every 3-6 months, depending on the intensity of use and the type of stored products.
How to remove the smell of fish from the refrigerator?
Adsorbents deal best with the smell of fish: activated carbon, soda or special chemistry with enzymes. It is also effective to wipe the walls with a solution of citric acid or vinegar, which neutralize the amines responsible for the fishy smell.
