The question is how to clean the inside of the refrigerator at home from yellowness and odor, becomes relevant for every home cook who is faced with the loss of presentability of kitchen appliances. Over time, even the highest quality plastic ages, and spilled products leave stubborn stains that cannot be removed with ordinary water. Yellowness on shelves and walls not only spoils the aesthetic appearance, but may also indicate the growth of bacteria or chemical reactions with fats.
There are many folk and professional methods, allowing the unit to return to its original whiteness and freshness. It is important to understand that the choice of product depends on the material of the inner surface, be it ABS plasticglass or metal. Incorrectly selected chemistry can completely destroy the structure of the polymer, making it brittle or changing color irrevocably.
In this article we will examine in detail safe cleaning methods that will help you cope with the most persistent stains. You will learn what ingredients you always have on hand and how to combine them correctly to achieve maximum effect without damaging your equipment.
Causes of yellowness and persistent odors
The first step to successful cleaning is to understand the nature of the contamination. Yellow plaque on plastic is most often formed as a result of the oxidation of fats that settle on the walls when storing products without packaging. This process is accelerated by temperature changes, for example, during defrosting or frequent opening of doors.
In addition, some types of plastic are prone to natural aging under the influence of ultrafilen radiation if the refrigerator is located near a window. UV rays they destroy molecular bonds in the polymer, which is visually manifested as a change in color. Odors arise due to the activity of microorganisms that actively multiply in hard-to-reach corners and drainage holes.
Why does plastic turn yellow?
Plastic turns yellow due to the reaction of fire retardants (substances that reduce flammability) with oxygen and warmth. Also, the cause may be nicotine deposits if the refrigerator is in the kitchen where people smoke.
It is also worth considering the quality of the water used for washing. Hard water leaves a mineral deposit that turns yellow over time and becomes rough to the touch. That is why it is important to use filtered or boiled water for final rinsing.
Preparing the refrigerator for general cleaning
Before taking active steps to remove stains, it is necessary to properly prepare the unit. The safety and efficiency of the process directly depend on the preliminary steps. First of all, the refrigerator must be completely defrosted by disconnecting it from the power supply.
Remove all shelves, drawers and containers. It is better to wash glass and plastic elements separately in a bathtub or large basin using warm water. This will allow you to gain access to the inner walls and corners where most of the dirt usually accumulates.
☑️ Preparing for washing
After defrosting, collect all drained water. It is important not to use a hairdryer or other heating devices for defrosting, as sudden temperature changes can damage evaporator or cause cracks in the plastic. Let the ice melt naturally by placing towels on the bottom of the chamber.
Folk remedies for removing yellowness from plastic
If you are looking for how to clean the inside of the refrigerator from yellowness at home, pay attention to the available household products. They are often more effective than aggressive chemicals and safer for health. One of the most effective methods is to use laundry soap in combination with warm water.
Grate a bar of soap and dissolve the shavings in hot water until you obtain a thick paste. Apply this mixture to the yellow areas and leave for 30-40 minutes. The alkaline environment of soap perfectly breaks down fatty deposits, which are the main cause of yellowness.
- 🧼 Laundry soap - a time-tested way to combat fat.
- 🍋 Lemon acid - dissolves mineral deposits and bleaches plastic.
- 🥔 Potato starch - acts as a soft abrasive and absorbent.
Another powerful tool is hydrogen peroxide. It has whitening properties and can return plastic to its snow-white appearance. Soak a cotton pad in a 3% peroxide solution and thoroughly wipe the problem areas. To enhance the effect, you can add a little baking soda to create an effervescent cleaning paste.
⚠️ Attention: Do not use chlorine-containing bleaches (for example, “White”) to clean colored plastic or sealing rubber bands, as chlorine can permanently destroy the structure of the material and increase the yellowness.
For A mixture of tooth powder and ammonia is also great for removing stubborn yellow stains. This combination works like a soft polisher, removing the top oxidized layer of plastic without scratching. After treatment, be sure to thoroughly rinse the product with clean water.
Professional chemicals and specialized products
When traditional methods fail, household chemicals come to the rescue. Modern manufacturers offer a wide range of cleaning products designed specifically for kitchen appliances. When choosing products, pay attention to the mark “for plastic” and the absence of abrasive particles.
Sprays for cleaning kitchen surfaces often contain surfactants that effectively emulsify fat. However, they must be washed off very carefully, as chemical residues can get on the food. Dishwashing gels are also suitable if diluted in warm water until foamy.
| Type of product | Effectiveness against yellowness | Safety for plastic | Necessity of rinsing |
|---|---|---|---|
| Dishwashing liquid | Average | High | Required |
| Kitchen spray (anti-grease) | High | Average | Required (multiple) |
| Melamine sponge | Very high | Low (risk of abrasion) | Required |
| Specialized cleaner for refrigerators | High | High | Depends on the instructions |
Deserve special attention melamine sponges. They work like an eraser, erasing dirt from the surface. However, they should be used with caution: too intense friction can make the plastic dull or damage its glossy finish.
Elimination of unpleasant odors: proven methods
After the question of how to clean the inside of the refrigerator from yellowness at home has been resolved, you need to start eliminating odors. Even after thorough washing, the odor may remain in the micropores of the plastic or in the drainage system. The simplest and most effective way is to use adsorbents.
Activated carbon is one of the best odor absorbers. Grind 10-15 tablets into powder and scatter into containers that need to be placed on shelves. Leave them for a day with the refrigerator door closed. Freshly ground coffee or soda also does an excellent job.
- ☕ Coffee grounds - absorbs odors and leaves a light aroma.
- 🍞 Black bread - pieces of stale bread quickly neutralize odors.
- 🍚 Rice or salt - act as natural air filters.
If the drainage hole emits an odor, it must be cleaned. Use a special brush or wire with cotton wool soaked in a disinfectant solution. Rinse the canal with warm water from a syringe or syringe.
Don't forget about the rubber seals. It is in their folds that mold often accumulates, which gives a musty smell. Wipe them with a solution of vinegar or hydrogen peroxide, thoroughly cleaning every millimeter of the surface. If the rubber has turned black and cannot be wiped off, it may need to be replaced.
Prevention of contamination and fridge care
In order not to constantly look for ways to clean the inside of the refrigerator, it is important to follow the operating rules. Regular maintenance takes less time than general cleaning. Try not to place hot foods inside, as steam settles on the walls and promotes the growth of bacteria.
All products must be packaged. Use containers with lids or cling film. This will prevent odors from mixing and grease or juice from splashing on the shelves. Wipe the shelves with a damp cloth once a week, without waiting for visible stains to appear.
⚠️ Attention: Never use hot water (above 40-50 degrees) to wash the interior of the refrigerator. A sharp temperature change can lead to deformation of plastic parts and the appearance of cracks.
Once a month, inspect the contents and throw away expired products. Also check the condition of the drainage hole. If the water stops draining, it means the channel is clogged and requires cleaning. Timely care will extend the life of your equipment and maintain its neat appearance.
How often should you wash the refrigerator?
Ideally, the inner chamber should be wiped once a week, and a general wash with defrosting should be carried out once every 3-6 months, depending on the type of refrigerator (No Frost or drip).
Is it possible to wash a refrigerator with window cleaner?
You can use window cleaner, but with caution. They work well for removing grease stains from glass shelves, but may contain alcohol or ammonia, which dry out plastic and rubber seals. If you do use such a product, rinse it thoroughly with water and wipe the surfaces dry.
Why did a strange chemical smell appear after washing?
This may be a consequence of using too concentrated a detergent that was not rinsed off well. The smell may also come from a new sponge or rag. In this case, you need to thoroughly wipe all surfaces again with a clean, damp cloth and ventilate the refrigerator with the door open for several hours.
How to remove traces of tape or stickers inside the refrigerator?
The best way to do this is with vegetable oil or a special “Antiscotch” product. Apply the oil to a cotton pad, apply to the remaining glue for a few minutes, then gently wipe off. After this, be sure to degrease the surface with dishwashing detergent to remove the oil film.
Is it safe to use a steam cleaner for plastic?
You can use a steam cleaner only if the instructions for your refrigerator indicate that the plastic is heat-resistant. In most cases, a jet of hot steam can deform thin plastic parts or damage the polymer structure, so it is better to refrain from this method or use the minimum steam temperature.
