Over time, even the most modern and expensive refrigerator can lose its original appearance. Owners often face the problem of persistent stains appearing on the internal walls, especially if the device has been in use for several years. This process is natural for plastic, but it can be significantly slowed down or even completely eliminated if you know the right cleaning methods. yellow stain on the internal walls, especially if the device has been in use for several years. This process is natural for plastic, but it can be significantly slowed down or even eliminated if you know the right cleaning techniques.
Greasey stains from meat, oil or sauces tend to be deeply absorbed into the porous structure of the plastic. If they are not removed in a timely manner, they become an ideal environment for the growth of bacteria and the appearance of an unpleasant odor. It is important to understand that aggressive chemicals can damage the coating, so it is worth considering gentle but effective home remedies.
Before starting the active cleaning phase, it is necessary to carry out proper preparation. This will not only protect you from electric shock, but will also allow you to efficiently process all hard-to-reach corners of the camera. Ignoring the preparatory stage often results in dirt simply being spread over the surface.
Preparation for general cleaning
The first and most important step is to completely disconnect the device from the power supply. You will need to remove all the shelves, vegetable drawers and egg containers. It is best to wash these removable elements separately in the bathtub or under the shower using warm water and standard dishwashing detergent.
While the plastic parts are drying, you should defrost the freezer if your refrigerator does not have a No Frost system. Even a thin layer of ice will interfere with proper cleaning of the walls. To speed up the process, you can use a hairdryer, but you should direct the hot air stream with care so as not to damage the seals.
Pay special attention to the condition of the sealing rubber. It is in the folds seal that mold and black spots most often accumulate, which subsequently spread the odor throughout the chamber. If the rubber is very dirty, it must be bent and washed thoroughly, but carefully, being careful not to tear it.
☑️ Preparing the refrigerator
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice. Damage to the evaporator will lead to freon leakage and expensive repairs.
Folk remedies against yellowness
Yellowness on plastic is often caused by oxidation of the material under the influence of light and time, as well as ingrained fats. One of the most affordable and effective remedies is baking soda. It acts as a mild abrasive without scratching the surface, and perfectly neutralizes odors.
To prepare a cleaning paste, mix soda with a small amount of water until the consistency of thick sour cream. Apply the resulting mixture to the yellow areas and leave for 15–20 minutes. After this, thoroughly wipe the surface with a damp microfiber. To enhance the effect, you can add a drop of lemon juice.
Another powerful tool in the fight against pollution is laundry soap. Unlike modern gels, it contains alkali, which perfectly breaks down fatty deposits. Grate the soap, dissolve the shavings in warm water and whip up a thick foam. It is foam that best penetrates the pores of plastic.
The secret of working with changing the color of plastic
If the yellowness is not caused by dirt, but by a change in the structure of the plastic (degradation), then it is impossible to wash it. In such cases, only painting with special paints for plastic or replacing parts helps.
Do not forget about hydrogen peroxide. This product has a whitening effect and is safe for food surfaces. Wipe the walls with a cloth soaked in a 3% peroxide solution and leave for a while. The method is especially good for removing traces of berries and vegetables.
Removing persistent greasy stains
Fat tends to polymerize, turning into a sticky, difficult-to-remove substance. Plain water will not help here; an emulsifier is needed. The best choice would be a dishwashing detergent designed to break down fats. Apply the gel to a sponge, lather and treat problem areas.
If the grease is old and located in the corners or at the joints of panels, use a toothbrush with soft bristles. Mechanical action in combination with a detergent will help remove dirt from microcracks. The movements should be circular, without strong pressure, so as not to leave scratches.
For very difficult cases, you can prepare a mixture of vinegar and alcohol in a 1:1 ratio. This solution degreases the surface and disinfects it. After treatment, be sure to wipe the refrigerator with clean water to remove acid residues and the specific odor.
| Remedy | Effectiveness against grease | Safety for plastic | Exposure time |
|---|---|---|---|
| Soda + water | Medium | High | 15-20 min |
| Vinegar 9% | High | High | 5-10 min |
| Dishing detergent | Very high | High | Instant |
| Alcohol | High | Medium (dries) | Instant |
Cleaning rubber seals
The rubber seal is the weak point of any refrigerator, where mold most often settles. Black dots on rubber are fungal colonies that not only spoil the appearance, but are also harmful to health. Chlorhexidine or hydrogen peroxide are excellent for removing them.
Take a cotton swab, generously moisten it with an antiseptic and thoroughly wipe each fold of the seal. If the mold has penetrated deeply, the procedure will have to be repeated several times. It is important not to rub the rubber with abrasive sponges, as the damaged surface will become even more susceptible to contamination.
After disinfection, it is recommended to lubricate the rubber with glycerin or a special rubber conditioner (can be found in automobile stores). This will restore elasticity to the seal and prevent the appearance of microcracks in which dirt accumulates. Dry and cracked rubber adheres worse to the body, which leads to loss of cold.
Elimination of unpleasant odors
Even after thorough washing, a musty smell may persist in the refrigerator. This often happens if food has been left in the chamber for a long time or milk has been spilled. To neutralize the aroma, use activated carbon.
Grind 10-15 tablets of activated carbon into powder and scatter it on saucers, placing them inside the chamber for a day. Charcoal is an excellent adsorbent that will absorb odor molecules. An alternative can be an open pack of soda or ground coffee.
If the plastic casing itself emits the odor (for example, after purchasing a new device or a long period of inactivity), wipe the walls with a solution of ammonia. Add one tablespoon of ammonia per liter of water. You should work in the wind!
What you should absolutely not use
When cleaning the refrigerator, it is important not to cause harm. There are a number of substances that can irreversibly damage plastic or disrupt the operation of the cooling system. First and foremost, avoid pure chlorine bleach. Aggressive chlorine destroys the structure of plastic, making it brittle and even more yellow over time.
It is also prohibited to use acetone, paint thinners and gasoline. These substances can melt the top layer of plastic or leave permanent matte marks. Abrasive powders for cleaning bathtubs and metal shavings will leave micro-scratches in which dirt will accumulate even faster.
It is not recommended to wash the internal chambers with hot water (above 40-50 degrees). Sudden changes in temperature can cause thin plastic to warp or crack, especially if the refrigerator has just defrosted and is still cold. Use water at room temperature or slightly warm.
⚠️ Attention: Do not pour water directly onto the ceiling of the chamber or into the air duct outlet area. Moisture getting inside the case can cause a short circuit or damage the electronic control.
Prevention of contamination
In order not to rack your brains over how to clean the refrigerator from yellowness and grease next time, it is worth implementing simple operating rules. Always store liquid foods and meats in closed containers. This will prevent accidental spills and splashes from spreading across the shelves.
Use special shelf mats. They can be easily removed, washed under the tap and returned to their place without affecting the refrigerator shelf itself. This greatly simplifies the cleaning process and protects the plastic from scratches and stains.
Regularly, at least once a month, do a quick inspection of the products and wipe the shelves with a damp cloth. Fresh stains are much easier to remove than old grease. Monitor the expiration dates of products to avoid package leaks and mold.
Life hack with newspaper
After washing, wipe the glass shelves with crumpled newspaper - this will give them shine and prevent fogging, although for modern refrigerators it is better to use microfiber.
Is it possible to wash a refrigerator with soapy water?
Yes, you can, but only if you use mild, fragrance-free soap and thoroughly rinse off the foam. Residues of soap can absorb food odors.
How often should you wash the inside of the refrigerator?
It is recommended to carry out general cleaning with defrosting once every 3-4 months. Preventive wiping of shelves - once every 2-3 weeks.
Why does plastic turn yellow in the refrigerator?
Yellowness occurs due to oxidation of the material under the influence of light, heat and contact with fatty acids contained in products.
How to remove the smell of fish from refrigerator?
A solution of vinegar or citric acid will help best. Freshly ground coffee or activated carbon tablets also effectively absorb the smell.
Is it dangerous to use a steam cleaner for plastic?
You need to use a steam cleaner with extreme caution. The high temperature of the steam can deform the thin plastic of the shelves and damage the seals.
