The refrigerator is the heart of a modern kitchen, a device that works around the clock, preserving food freshness and our health. However, over time, even the most reliable equipment requires updating not only functional, but also aesthetic. The internal space of the unit is constantly exposed to moisture, temperature changes and microparticles of food, which inevitably leads to the appearance of persistent odors, yellowing of the plastic or even microscopic cracks on the shelves. Many owners don’t even think that an old, tarnished refrigerator that smells like “last lunch” may work less efficiently due to dirty evaporators or broken seals.
The question of how to update the inside of the refrigerator often arises before owners when standard wet cleaning ceases to give the desired result. This may be due to the desire to freshen up the kitchen interior, sell appliances at a higher price, or simply provide ideal hygiene for the family. The upgrade process does not always involve the purchase of a new expensive unit; Often it is enough to wisely choose cleaning products, replace individual elements of the interior, or carry out professional disinfection. In this article we will analyze all available methods, from budget folk recipes to the use of specialized chemicals and replacement of components.
It is important to understand that the internal coating of the refrigerator compartment is not just plastic, but a complex composite material that requires delicate handling. Aggressive solvents can destroy the structure of the polymer, making it porous, which will further lead to even faster absorption of odors and the proliferation of bacteria. Therefore, before you grab the first household chemical you come across, you need to clearly define the purpose of the update: eliminating odor, removing stains, restoring whiteness or replacing physical elements of the interior.
Diagnostics of the state of the internal space
Before taking active steps to update, it is necessary to conduct a thorough audit of the internal condition of the unit. Often the problem lies not in general wear and tear, but in local contamination or malfunctions that are easy to fix. Carefully inspect the walls of the chamber: the presence of yellow spots may indicate contact with fat or oxidation of the plastic, and a sticky coating may indicate the growth of bacteria or mold. Pay special attention to hard-to-reach areas, such as panel joints and the area around the sealing rubber, where dirt accumulates over the years.
If you find that the plastic has lost its original color and has become gray or yellowish, this is a signal for deep cleaning. Yellowness of plastic often caused by oxidative processes under the influence of oxygen and light, as well as a reaction to products combustion if the refrigerator was standing next to a gas stove. In some cases, color changes may be caused by the migration of dyes from the packaging materials of products stored in the chamber for a long time.
Check the integrity of glass shelves and plastic containers. Microcracks in glass are not only dangerous, but also an ideal place for dirt to accumulate that cannot be washed off. Cracked plastic boxes on the door also require replacement, as colonies of microorganisms grow in the cracks. If you are planning to sell equipment, the presence of such defects can significantly reduce its market value, so eliminating them is a priority.
⚠️ Attention: If you find black mold in the drainage hole or on the seal, regular washing will not help. Treatment with specialized fungicides that are safe for contact with food is required.
Assess the condition of the system No Frostif it is present in your model. An evaporator behind a plastic panel clogged with dust and lint can cause an unpleasant odor and reduce cooling efficiency. Sometimes, for a complete update, it is necessary to remove the back wall and blow out the system with compressed air, which is a more complex procedure that requires certain skills.
Professional chemicals and specialized products
The modern market of household chemicals offers a wide range of products designed specifically for the care of refrigeration equipment. Unlike universal cleaners, they do not contain abrasive particles or aggressive solvents that can damage food-grade plastic. The basis of such products are surfactants (surfactants), which effectively break down fatty contaminants, and antibacterial components that destroy up to 99.9% of known bacteria. Using specialized chemicals is the fastest way to return your refrigerator to its salable condition.
When choosing a product, pay attention to its composition. To renew white plastic, sprays containing active oxygen or enzymes are ideal, which gently whiten the surface without the use of chlorine. Chlorine-containing products such as “Belizna” can be used, but with extreme caution and only in strong dilution, as they can make the plastic brittle and cause it to turn yellow in the long term. Electrolux E6RCI106 or Liebherr cleaning spray are examples of quality products from equipment manufacturers.
To remove persistent odors that absorbed into plastic, there are special absorbers and neutralizing sprays. They do not mask the aroma with fragrances, but chemically bind odor molecules, making them inert. Such products are especially effective after storing strong-smelling foods such as fish, onions or smoked meats. Regular use of antibacterial sprays helps maintain hygienic cleanliness and prevents mold.
Don't forget about the rubber seals. To renew them and maintain elasticity, there are special silicone lubricants and conditioners. They prevent rubber from cracking, improve door fit and extend the life of the seal. Treating gum with this composition once every six months is an excellent prevention of loss of cold and the formation of ice.
Folk methods: soda, vinegar and other recipes
If using store-bought chemicals for some reason is impossible or you prefer environmentally friendly solutions, time-tested folk remedies will come to the rescue. They are available, cheap and, as a rule, safe for health. One of the most effective means for updating plastic and removing yellowness is a paste of baking soda. Soda works as a mild abrasive and an excellent adsorbent, absorbing odors and drawing out contaminants from the pores of plastic.
Table vinegar is another powerful tool in the fight for cleanliness. The acidic environment of vinegar perfectly dissolves mineral deposits (scale) that can form on the walls of the chamber due to condensation, and kills most types of bacteria. To prepare a cleaning solution, mix water and 9% vinegar in a 1:1 ratio. This solution also perfectly polishes stainless steel surfaces if it is used in the interior design of the model.
Hydrogen peroxide can be used to remove difficult stains and whiten plastic. It acts as a mild oxidizing agent, destroying organic pigments that cause yellowness. Soak a cotton pad in a 3% peroxide solution and wipe the problem areas. This method is especially effective for local removal of stains from berries, juices or spices that are deeply embedded in the structure of the material.
⚠️ Attention: Never mix vinegar and chlorine-containing products (for example, Bleach). As a result of the reaction, chlorine gas is released, which is toxic and dangerous for the respiratory tract.
Citric acid has also proven itself as an excellent tool for removing grease and giving plastic a fresh look. Dissolve a packet of citric acid in a glass of warm water and wipe all internal surfaces with this solution. Citric acid not only cleans, but also leaves a pleasant, subtle citrus aroma, which, unlike artificial fragrances, will not interrupt the smell of food.
Mechanical renewal: replacing shelves and drawers
Sometimes no amount of cleaning can return the refrigerator to a neat appearance if the internal elements are physically worn out. Cracked shelves, cloudy containers and chipped door boxes are not only an aesthetic problem, but also a safety issue. Fortunately, most manufacturers offer the option to purchase individual components. Replacing these elements allows you to actually get a “new” refrigerator inside, while maintaining the functionality of the main unit.
To order the correct spare parts you will need model number your refrigerator. It is usually located on a sticker inside the camera or on the back of the device. Knowing the exact model, you can find original tempered glass shelves or high-quality analogues from third-party manufacturers. Glass for refrigerators must be heat-resistant and withstand significant temperature changes, so the use of ordinary glass is strictly prohibited.
Plastic elements, such as crisper boxes and gallon bins, lose their transparency over time and become brittle. The new plastic not only looks more aesthetically pleasing, but is also easier to clean. When replacing, pay attention to the fastening system: it must exactly match the original so that the shelf does not fall out when the door is opened. In some models, it is possible to install universal grid shelves that can be cut to the desired size.
☑️ Finding and replacing components
If it is impossible to find original spare parts or they are too expensive, you can consider the option of making elements to order in glass workshops or using universal organizers. However, universal solutions may not provide ideal air circulation, which is critical for freshness areas. Therefore, priority should always be given to details designed specifically for your model.
Odor elimination and antibacterial treatment
Odor is one of the main enemies of comfort in the kitchen. Even if the refrigerator is visually clean, lingering smell (lingering, long-lasting smell) can spoil the taste of food. For deep disinfection and odor elimination, it is not enough to simply wipe the surfaces. It is necessary to treat all internal volumes, including the ventilation system. To do this, you can use an ozonizer: place a small household appliance inside a closed refrigerator for 15-20 minutes. Ozone effectively oxidizes organic odor molecules and kills bacteria.
Activated carbon, silica gel or special carbon filters for refrigerators can be used as absorbents that will work continuously after cleaning. These materials have a porous structure that captures odor molecules from the air. Place several bags of charcoal on different shelves and the air in the chamber will always be fresh. It is recommended to change such filters once every 3-4 months.
For antibacterial treatment, you can use solutions based on silver ions or special wipes with antibacterial impregnation. They create a thin film on the surface of the plastic that prevents the proliferation of microorganisms. This is especially true for families with young children or people with weakened immune systems. Regular treatment with such products reduces the risk of food poisoning.
What to do if the smell remains after cleaning?
If the smell does not go away after thorough washing and treatment, it may have penetrated the thermal insulation layer. This happens when the internal circuit is depressurized. In this case, it is necessary to disassemble the refrigerator and replace the insulation, which only service center specialists can do.
Do not forget about the drainage hole. This is where mucus and mold often accumulate, which are the source of the musty smell. Clean the hole using a special brush or a cotton swab dipped in a disinfectant solution. Pour some warm water into the drainage to make sure that it flows freely into the container above the compressor.
Comparative table of updating products
To make it easier for you to navigate the variety of methods and means, we have prepared a comparison table. It will help you choose the best option depending on the type of contamination and your preferences. Remember that combining methods often gives the best result: for example, mechanical cleaning with soda followed by treatment with an antibacterial spray.
| Mean/Method | Effectiveness against grease | Elimination of odors | Safe for plastic | Cost |
|---|---|---|---|---|
| Specialized spray | High | Average | High | Medium |
| Baking soda | Medium | High | Very high | Low |
| Vinegar solution | Low | High | High | Low |
| Hydrogen peroxide | Low | Average | High | Low |
| Replacement of components | N/A (100% update) | 100% | N/A (New material) | High |
When choosing a method, always proceed from the material, from which the interior surfaces of your refrigerator are made. Glossy plastic is more sensitive to scratches than matte and requires gentler cleaning agents. Textured surfaces, on the contrary, are better cleaned with a soft-bristle brush to wash away dirt from the relief.
Prevention and care of an updated refrigerator
After you have carried out a large-scale update, it is important to maintain the achieved result for as long as possible. Proper operation and regular, albeit minimal, care will allow you to forget about the problem of yellowness and odors for years. The main rule is to prevent dirt from accumulating. Wipe shelves and walls with a damp cloth immediately if anything spills or falls apart. It takes seconds, but prevents the formation of permanent stains.
Use the correct container to store food. Store bulk foods, meat, fish and prepared meals in airtight containers. This not only prevents odors from mixing, but also protects the refrigerator walls from coming into contact with potential contaminants. Opened products are the main reason for the appearance of plaque and germs inside the chamber.
Perform a quick preventative cleaning once a month. Remove food, wipe down shelves with a mild detergent, and check expiration dates. Such a “general five-minute” will not allow dirt to take hold. Also monitor the temperature: too low a temperature contributes to the formation of excessive condensation, which, when mixed with dust, forms dirt.
⚠️ Attention: Refrigerator manufacturers may change the composition of plastic and care recommendations in different product lines. Always check the official instructions (User Manual) for your specific model so as not to damage the coating with new, more aggressive compounds.
Regularly check the condition of the seals and, if necessary, lubricate them with glycerin or special silicone grease. A clean and elastic rubber band is a guarantee that warm air will not enter the refrigerator, causing the formation of ice and unnecessary load on the compressor. Taking good care of your equipment pays off with a long and trouble-free service.
Frequently asked questions (FAQ)
Is it possible to wash the inside of the refrigerator with dishwashing detergent?
Yes, you can, but with caution. Use only soft, non-abrasive gels without harsh fragrances or bleaches. The main thing is to rinse off the foam very thoroughly with water, since chemical residues can be absorbed into the plastic and subsequently transmit the smell to the products. It is better to use solutions on a natural basis.
How to remove yellowness from the white plastic of a refrigerator?
A mixture of hydrogen peroxide and baking soda until it becomes a paste works most effectively. Apply the mixture to the yellow areas, leave for 30-60 minutes (you can use sunlight or an ultraviolet lamp to activate the reaction), then rinse. For strong yellowness, the procedure can be repeated.
How can you replace activated carbon to absorb odors?
As an alternative, you can use an open bag of rice, ground coffee (in a sachet so it doesn’t spill), a slice of black bread or cotton wool soaked in vanilla extract. However, a special carbon filter works more efficiently and lasts longer.
Is it safe to use a steam cleaner to clean the inside?
It is not recommended to use a steam cleaner inside the refrigerator compartment. Sudden temperature changes and large amounts of moisture can damage plastic parts, cause shelves to warp, or allow water to enter electrical components and insulation. It is better to use a damp cleaning cloth.
How often should you carry out general cleaning of the refrigerator?
It is recommended to completely defrost and thoroughly clean the refrigerator every 3-6 months, depending on the intensity of use. If you have pets or small children, it is better to increase the frequency to once every 2-3 months.
