Hygiene of kitchen appliances is not just a matter of aesthetics, but a critical procedure for maintaining the health of household members. The inside of the chamber where food is stored creates an ideal environment for bacteria to multiply, especially if spilled liquids or crumbs are not cleaned up in a timely manner. Regular disinfection surfaces prevent the appearance of unpleasant odors and prolong the service life of seals.
Many owners make the mistake of using aggressive household chemicals, which can damage plastic elements or leave toxic traces on the shelves. Refrigerators different brands, be it Bosch, LG or Indesit, require a delicate approach to cleaning, since plastic easily absorbs odors and is scratched by abrasives.
In this guide we will look at proven methods for cleaning technology to shine without harming materials. You will find out which folk remedies work better than store-bought sprays, and why you can’t ignore the drainage hole.
Preparation of equipment and selection of safe products
Before starting the active phase of cleaning, it is necessary to prepare a working arsenal. Don't rely on water alone, as greasy stains and dried-on dirt require the right solvent. The basic rule is: the product must be effective, but safe for contact with food.
Natural ingredients are ideal for cleaning internal chambers. Citric acid does a great job of removing scale and grease, while baking soda works as a mild abrasive and deodorizer. If you prefer ready-made solutions, choose gels marked “for children's things” or specialized sprays for kitchen appliances.
⚠️ Attention: It is strictly prohibited to use chlorine-containing products (“Whiteness”) and powders with large abrasive particles. Chlorine can damage the structure of plastic, and scratches become an ideal place for bacteria to accumulate.
You will need soft sponges, microfiber and paper towels. Leave hard brushes for cleaning grates on the stove; they are too aggressive for the refrigerator. Also prepare a container for water and a spray bottle for easy application of solutions.
Defrosting algorithm: No Frost and drip system
The process of preparing for washing directly depends on the type of cooling system of your unit. Errors at this stage can lead to compressor failure or damage to the evaporator. Always start by disconnecting the device from the power supply.
If you have a model with drip system (crying evaporator), defrosting is required. Leave the doors open for at least 6-8 hours, preferably overnight. You cannot speed up the process with a hairdryer or hot water - a sharp temperature change is dangerous for the refrigerant pipes.
For systems No Frost full defrosting is required less often, usually once a year, but wet cleaning is still necessary. In such models, it is important to allow condensation to drain from the tray, which is often hidden behind the back wall or at the bottom of the case.
☑️ Checklist for preparing for washing
While the defrosting process is in progress, remove all removable elements: glass shelves, plastic containers, bottle holders and egg trays. It is more convenient to wash them separately in the bathroom under running water.
Do not forget to lay old towels or rags on the floor around the refrigerator so that water does not flow under the baseboard or to the neighbors below. This is especially true for models where the drainage hole may be clogged with ice.
How to clean the inside of a refrigerator: a review of effective solutions
The choice of cleaning agent depends on the degree of contamination and the material of the internal surfaces. Plastic, glass and rubber require different approaches. Below is a comparative description of popular cleaning methods.
| Measure | What is it suitable for | Mixing proportions | Features |
|---|---|---|---|
| Soda solution | Removal odors, fat | 2 tbsp. spoons per 0.5 liters of water | Requires thorough rinsing |
| Vinegar 9% | Disinfection, mold | 1 part vinegar to 2 parts water | Pungent odor, quickly erodes |
| Lemon juice | Polishing, fresh aroma | Juice of 1 lemon per 1 liter of water | Brightens yellow plastic |
| Laundry soap | Heavy contamination | Shavings dissolved in water | May leave a film |
The most versatile and safest solution is considered to be a solution of baking soda. It is non-toxic, perfectly breaks down fat deposits and neutralizes odors. After treating with soda, the surfaces become matte and clean.
Vinegar solution is a powerful weapon against bacteria and mold. If you notice black spots in the corners or on the seals, use this. However vinegar should not be mixed with hydrogen peroxide in a closed container, as this can lead to a chemical reaction.
The secret of clean glass
To make glass shelves shine and leave no streaks, wipe them with the solution water with ammonia (1 teaspoon per liter) or use a window cleaner, but rinse it thoroughly afterwards.
Step-by-step instructions: how to wash the camera and parts
When the removable elements are washed and dried, and the ice in the chamber has melted, we proceed to the main cleaning. Move from top to bottom so that dirty water does not drip onto already washed areas.
Start from the ceiling of the chamber and the upper shelves. Wet the sponge generously in the solution of your choice and use gentle circular movements to scrub the surfaces. Pay special attention to corners and joints where invisible dirt often accumulates.
- 🧼 Wipe the side walls thoroughly, not forgetting the shelf guides.
- 🥩 Remove traces of meat or fish with a disinfectant solution of vinegar.
- 🍋 Wipe the door handles and the outer ends of the shelves, as they are most often touched with dirty hands.
Wash glass shelves with warm water with the addition of dish soap, then rinse and wipe dry with microfiber. This will prevent the appearance of streaks and the accumulation of condensation.
Plastic vegetable boxes (zone Fresh Zone) often have a rough texture into which dirt gets clogged. Use a soft toothbrush to clean hard-to-reach places and textured surfaces.
Care for the seal and drainage hole
The rubber seal around the perimeter of the door is a weak spot where mold settles first. If you do not clean it, the refrigerator will no longer seal tightly, which will lead to an increase in energy consumption.
Carefully bend the elastic band and wipe the inner fold with a cotton swab dipped in vinegar or hydrogen peroxide. This will remove the black coating and restore elasticity to the rubber.
⚠️ Attention: Do not use oils (vaseline, vegetable) to lubricate the seal unless the manufacturer recommends this in the instructions. Oils can destroy the rubber structure, causing it to swell or crack.
The drainage hole is located on the back wall of the refrigerator compartment. It often becomes clogged with crumbs and mucus. You can clean it using a special brush (often included) or a soft wire wrapped in cotton wool.
After cleaning, pour a little clean water into the hole to make sure that it flows freely into the compressor pan. If the water is stagnant, repeat the cleaning procedure.
How to remove persistent odors and stains
Sometimes, even after general cleaning, the unpleasant smell of missing food or spilled milk remains in the refrigerator. Normal ventilation does not always help, as the smell could be absorbed into the plastic.
To eliminate odors, use natural absorbers. Place open containers with activated carbon, ground coffee or soda on the shelves. These substances work as adsorbents, pulling odor molecules from the air.
- 🍞 A piece of black bread, left on a plate for a day, perfectly absorbs extraneous odors.
- 🍋 A slice of lemon or orange will not only freshen the air, but also give a light citrus aroma.
- 📰 Crumpled newspapers placed inside a closed refrigerator overnight also help remove mustiness.
If a specific stain (such as spilled yogurt or juice) is smelling and won't come off, try making a paste of baking soda and water, applying it to the stain and leaving for 15-20 minutes. Then carefully remove with a soft sponge.
For old, stubborn stains on plastic, you can use a melamine sponge. It works like an eraser, removing the thinnest layer of dirt. However, use it with caution and only on glossy surfaces, having first checked it on an inconspicuous area.
Frequently asked questions and common mistakes
Many users ask questions related to the frequency of cleaning and the safety of the process. Answering them will help you avoid common mistakes.
One of the main mistakes is washing the refrigerator without first defrosting it (if it is not No Frost). Scraping ice with a knife can lead to breakdown of the cooling system, after which repairs will be very expensive.
Also, do not turn on the device immediately after washing. Let it dry completely (15-20 minutes) so that moisture does not get into the electrical contacts or the light bulb.
Can you wash the refrigerator with soap?
Yes, you can use laundry or baby soap, but it must be rinsed off very carefully. Remains of soap film can give products an off-flavor.
Regularity is the key to success. It is recommended to carry out general cleaning with defrosting once every 3-4 months, and simply wipe the shelves with a damp cloth once a week when replacing products.
Is it possible to wash the refrigerator with dishwashing detergent?
Yes, you can, but only if it does not contain aggressive fragrances and is easily washed off. Rinse the surfaces thoroughly, as the greasy film from Feri or analogues can stick to food and absorb odors.
How often do you need to defrost a No Frost refrigerator?
The No Frost system does not require frequent defrosting to remove ice, but once a year it still needs to be turned off for washing and disinfection. This is also necessary if you notice a decrease in cooling efficiency.
What is dangerous about using bleach inside the chamber?
Chlorine is toxic and can react with food residues. Chlorine vapor can be absorbed into plastic and rubber seals and then slowly released into food. This is dangerous to health.
What to do if there is a chemical smell left after washing?
It is necessary to re-wipe all surfaces with clean water with the addition of lemon juice or vinegar. Leave the doors open for several hours to ensure complete ventilation. Use odor absorbers (charcoal, soda).
Is it possible to use a steam cleaner?
It is not recommended to use a steam cleaner inside the refrigerator compartment. The high temperature of the steam can deform the thin plastic of the shelves and damage the seals. Steam is only suitable for external washing of the body, if the material allows it.
