Cleanliness inside the refrigerator is not only an aesthetic issue, but also a guarantee of food safety. Over time, greasy stains, drops of sauces, traces of berries and specific odors accumulate on the inner walls, shelves and drawers, which are absorbed into polymer materials. If you ignore regular cleaning, microorganisms begin to actively multiply, which can lead to food spoilage and the appearance of mold.
Owners are often faced with a dilemma: how to wash the surface so as not to damage its structure and not leave toxic traces on the food. Modern household chemicals offer many solutions, but many of them are too aggressive for food-grade plastic. In this article, we will analyze proven methods that allow you to effectively remove contaminants of any complexity, while maintaining the integrity and appearance ABS plastic.
It’s worth starting with the fact that the choice of cleaning agent directly depends on the type of contaminant and how long ago it appeared. Fresh stains are usually easily removed with warm water, while old grease or ingrained odor require a more serious approach.
Preparation for cleaning: required steps
Before you start actively using cleaning products, it is necessary to properly prepare the unit for the procedure. The most common mistake is trying to clean the internal chambers while the device is connected to the network. This is not only unsafe due to the risk of a short circuit if moisture enters, but also ineffective, since the compressor will work, interfering with defrosting.
The first step should always be to completely disconnect the device from the power supply. After this, you should remove all the products and put them in a cool place or in a thermal bag. If an ice build-up has formed on the walls, you should not chip it with a knife, as there is a high risk of damaging evaporator or breaking through the circuit with freon.
⚠️ Attention: Never use sharp metal objects to chip ice. Damage to the evaporator tubes will lead to a refrigerant leak and expensive repairs, which are often not economically feasible.
Next you need to remove all removable elements: shelves, drawers, egg containers and bottle holders. It is more convenient to wash them separately in a bathtub or tray, using more intensive methods, which can be dangerous for non-removable parts of the body. It is better to soak plastic parts in warm water for 15–20 minutes to soften dried-on dirt.
Folk remedies for safe cleaning
Home recipes are often more effective than store-bought chemicals, especially when it comes to food surfaces. They do not contain aggressive fragrances and surfactants that can be absorbed into the structure of the material. One of the most popular and safest products is baking soda.
Soda has a mild abrasive effect and perfectly neutralizes unpleasant odors. To prepare the solution, you need to dilute 2 tablespoons of powder in a liter of warm water. The resulting liquid is used to wipe all internal surfaces, paying special attention to corners and joints, where bacterial plaque often accumulates bacterial plaque.
- 🍋 Citric acid or lemon juice - perfectly removes greasy stains and gives a pleasant fresh aroma, killing germs.
- 🍶 Table vinegar (9%) - effective against mold and complex contaminants, but requires careful ventilation after use.
- 🧼 Laundry soap is a natural remedy that copes well with grease stains on door seals.
Another powerful remedy is ammonia. It is ideal for removing yellow discoloration from white plastic and eliminating stubborn odors. However, you need to work with it carefully: ammonia vapors are toxic, so it is better to keep the door to the kitchen open and protect your hands with gloves. After treating with ammonia, the surfaces must be wiped with a clean, damp cloth.
Household chemicals: what is possible and what is not
When traditional methods fail, household chemicals come to the rescue chemistry. However, the market is oversaturated with products that can cause irreparable damage to the internal coating of the refrigerator. The main task is to choose a product that disinfects and degreases, but does not dissolve the plastic itself.
It is strictly forbidden to use products containing chlorine (for example, the popular “Whiteness” in its pure form) or strong solvents such as acetone. Chlorine makes plastic brittle and brittle and can also corrode metal parts. Solvents can literally melt the top layer of the coating, leaving sticky stains that cannot be removed.
| Type of product | Can be used | Cannot be used | Risk |
|---|---|---|---|
| Sprays for kitchen | Yes (rinse thoroughly) | No (if they contain chlorine) | Chemical burn of plastic |
| Glass cleaners | Yes (for shelves) | No (with ammonia for seals) | Rubber drying out |
| Abrasive powders | No | Yes (Pemolux and analogues) | Scratches and dullness |
| Solvents | No | Yes (Acetone, White spirit) | Surface dissolution |
The best choice would be specialized sprays for cleaning refrigerators or soft gels for washing dishes. They are designed to withstand food contact and can be easily washed off with water. When using sprays, it is better to apply them not directly to the wall, but to a soft cloth or sponge to avoid chemicals getting into the ventilation holes.
Removing complex stains: grease, glue and yellowness
The most difficult cases are old grease, traces of tape or stickers, as well as yellowing of the plastic over time. Grease deposits, especially near the freezer or on the top shelf, can turn into a sticky crust. To remove it, dishwashing detergent mixed with hot water or a special degreaser are excellent. Traces of labels and tape often remain after purchasing a new device or when changing product labels. To remove them, you can use vegetable oil: apply it to a cotton pad and rub the dirt until the glue is completely dissolved. After this, the greasy mark is removed with dishwashing detergent. degreaser.

Yellowness on plastic is the result of oxidation of the material under the influence of light and time. Hydrogen peroxide or a mixture of soda and tooth powder will help restore whiteness. The paste is applied to the problem area, left for 30–40 minutes, and then washed off. To enhance the effect, the treated surface can be exposed to direct sunlight for a couple of hours (after turning off the refrigerator).
⚠️ Attention: When using hydrogen peroxide or bleaches for plastic, avoid getting the product on the rubber door seals, as they may lose elasticity and begin to crumble.
Cleaning removable plastic ones elements
Shelves, drawers and containers made of transparent plastic (often polystyrene) require a special approach. This material is more fragile and sensitive to temperature changes than the main body of the refrigerator. The main mistake is to wash cold shelves with hot water. Due to a sharp temperature change, the plastic may crack or become covered with a network of microcracks.
Allow the removed parts to warm up to room temperature for 20–30 minutes. Only after this can they be washed. Warm water with vinegar or a mild detergent is ideal for cleaning clear drawers. If there are scratches on the plastic, you can try to polish them with a soft toothpaste without whitening particles.
- 🧽 Use only soft sponges, avoiding the hard side, so as not to scratch the transparent plastic.
- 🌡️ Dry the elements at room temperature, without using a hair dryer or battery to speed it up process.
- 🚫 Do not wash plastic parts in the dishwasher unless the manufacturer has explicitly indicated this option, since high temperatures can deform them.
Pay special attention to the shelf guides. They often accumulate dirt and mold. You can clean narrow grooves with an old toothbrush dipped in soapy water. This will ensure easy sliding of the shelves and prevent the appearance of foreign odors.
☑️ Checklist for cleaning removable parts
Care for seals and ventilation
The rubber seal around the perimeter of the door is a critical element that ensures the tightness of the chamber. This is where black mold most often settles, which is difficult to remove. To clean the folds of the seal, it is convenient to use cotton swabs soaked in a solution of vinegar or hydrogen peroxide.
After cleaning, it is recommended to lubricate the rubber with a special rubber care product or regular glycerin. This will maintain the elasticity of the material, prevent it from drying out and cracking, which will extend the life of the refrigerator. If the seal has lost its shape, you can try to straighten it with a hairdryer, gently heating the deformed areas.
The ventilation holes on the back wall also need periodic cleaning. Openings clogged with dust and lint impair air circulation, forcing the compressor to work under increased load. You can blow them out using a dust blower or vacuum cleaner at minimum power.
How often should you do general cleaning?
It is recommended to completely defrost and wash the refrigerator at least once every 3-4 months. This will prevent the formation of a thick layer of ice and corrosive contaminants that are more difficult to remove.
Typical mistakes when cleaning plastic
Even knowing how to clean plastic, many make mistakes in the process, nullifying efforts or leading to damage to property. The most common one is insufficient rinsing. Residues from a detergent, even a safe one, can react with food or simply smell unpleasant, transferring this odor to the food.
Another mistake is using hard brushes and scrapers. Even if scratches are not visually visible, the surface microrelief is disrupted. In the future, dirt will clog into these micro-scratches, and it will be almost impossible to wash it off. The plastic will become rough and dull.
- 🚫 Using a high-pressure steam cleaner can deform the thin plastic of the shelves.
- 🚫 Using chlorine tablets for dishwashers to soak parts.
- 🚫 Ignoring the instructions manufacturer, where specific requirements for your model may be indicated Samsung or Bosch.
It is also important not to forget about the outside of the door. fingerprint coatings (anti-reflective) on modern models require the use of special polishes for stainless steel or soft microfiber. Plain water will leave stains on them that will ruin the appearance of the equipment.
Drying and completing the process
After all surfaces have been washed with clean water, the drying stage begins. Humidity is the main enemy of the refrigerator, promoting the growth of bacteria and mold. Wipe all parts dry with a soft, lint-free towel or microfiber.
Do not rush to immediately plug in the device and load products. Leave the doors open for at least 1-2 hours to allow any residual moisture to evaporate completely and the smell of cleaning products to dissipate. If the room is hot, this process will go faster.
Only after making sure that it is completely dry and free of foreign odors, you can put the structure back together, put the shelves in place and connect the refrigerator to the power supply. It is recommended to load products 30–40 minutes after switching on, when the operating temperature has been established inside.
Can a melamine sponge be used to clean plastic?
A melamine sponge acts as a micro-abrasive. Although it is effective at removing stains, with frequent use it can dull glossy plastic and leave micro-scratches. Use it with caution only in difficult areas and only if the plastic is not glossy.
How to remove the burning smell if the product is burnt?
You need to throw away the source of the smell, wash all surfaces with a solution of vinegar or soda. After this, place activated carbon, ground coffee or special odor absorbers inside. Ventilate the refrigerator with the door open for several hours.
How to wash a refrigerator handle that has become sticky?
The stickiness of handles is often caused by the destruction of the Soft-Touch coating. Try cleaning them with alcohol or nail polish remover without acetone. If this does not help, you may need to replace the handle or cover it with decorative film.
Is it safe to use wet wipes for equipment?
Yes, special wet wipes for household appliances or monitors are safe for plastic. They do not contain high concentrations of alcohol and do not leave lint. However, for greasy stains they may not be enough; pre-treatment with a soap solution will be required.
