The refrigerator is the only household appliance that works without interruption 24/7, accumulating inside not only food, but also bacteria, mold, grease stains and unpleasant odors. Even if the equipment looks clean on the outside, microorganisms that are hazardous to health can grow in the nooks and crannies of the freezer or under the rubber seals. Regular cleaning not only extends the life of the unit, but also prevents food spoilage, saves energy (dirty capacitors increase the load on the compressor) and protects against breakdowns.
This article contains information on complete cleaning of the refrigerator, including defrosting, disinfecting, caring for seals and external surfaces. We will look at which products are safe for step-by-step instructions for complete cleaning of the refrigerator, including defrosting, disinfection, care of seals and external surfaces. We will analyze which products are safe for No Frostand which are suitable for older models with a drip system, how to eliminate persistent odors (including “fishy” and “rotten”) and what to do with hard-to-reach areas. Let us separately dwell on mistakes that 90% of users make when washing the refrigerator —they lead to breakdowns or re-contamination within a week.
1. Preparing for cleaning: what needs to be done before washing
Starting cleaning with hot water and a rag is a grave mistake. Without preparation, you risk flooding the kitchen, damaging electronic modules, or leaving food unrefrigerated for several hours. Here required checklist before starting work:
Turn off the power (unplug from the socket!)
Take out all the products and put them in a cooler bag or a bowl of ice
Remove all shelves, drawers and grilles (if they are removable)
Prepare the following: soda, vinegar, soft sponge, microfiber
Check the temperature in the room (optimally +18...+25°C for defrosting)-->
Pay special attention products: it is better to place perishable items (meat, fish, dairy products) in a thermal bag with cold accumulators or wrap them in cling film and wrap them in a towel. If it’s winter outside, you can take them out to the balcony (at a temperature no higher than +5°C). Never leave food at room temperature for more than 2 hours - this violates sanitary standards and leads to the proliferation of salmonella or listeria.
⚠️ Attention: If your refrigerator is equipped with an electronically controlled system (for example, model No Frost with electronic control (for example, models Samsung RB30A3200SA or LG GA-B409SLGL), do not press the defrost button manually - this may reset the settings. Simply turn off the power.
For models with mechanical thermostat (for example, Atlant XM-4021-000 or Biryusa 100) before defrosting, set the temperature regulator to the “0” or “Off” position. This will prevent the compressor from automatically starting when connected to the network.
2. Defrosting: how to speed up the process and avoid puddles on the floor
Defrosting is the longest cleaning stage, especially if more than 5 mm of ice has accumulated in the freezer. In modern refrigerators, ice rarely forms, but even they require defrosting every 6–12 months for prevention. Here No Frost ice rarely forms, but even they require defrosting every 6–12 months for prevention. Here 3 ways to speed up melting without any risk to equipment:
- 🧊 Natural defrosting: leave the doors open for 4-8 hours (depending on the thickness of the ice). Place towels or baking sheets underneath to catch the water.
- 💨 Fan: Direct the air flow from the fan at the ice build-up. This will reduce the time to 2-3 hours.
- 🍳 Pan with hot water: place it on a wooden stand (not on plastic!) inside the chamber and close the door for 10-15 minutes. Repeat until the ice comes off.
Never use a knife, fork or other sharp objects to chip ice - this damages the evaporator and leads to freon leakage. If the ice does not come off, moisten it with warm water from a spray bottle and carefully pry plastic spatula (for example, for ice cream).
| Ice thickness | Defrosting time | Recommendations |
|---|---|---|
| Up to 3 mm | 1–2 hours | Natural thawing is sufficient |
| 3–10 mm | 3–5 hours | Use a fan or a pan of water |
| More than 10 mm | 6–12 hours | Requires full defrosting with cleaning the drainage hole |
After the ice has melted, thoroughly wipe all surfaces dry ragto remove moisture. Pay attention to drainage hole (usually located on the back wall of the refrigerator compartment) - it needs to be cleaned with a cotton swab or a special brush (included with some models, for example, Bosch KGE39AW25R).

3. Cleaning interior surfaces: which products are safe
For washing interior walls, shelves and drawers prohibited. use abrasive powders, chlorine-containing bleaches or products with ammonia - they damage plastic and leave toxic fumes. Optimal options:
- 🧼 Baking soda: 2 tablespoons per 1 liter of warm water. Removes grease, disinfects and neutralizes odors.
- 🍋 Vinegar solution: 1:1 with water Effective against mold, but requires ventilation after use. data-i="121">Vinegar solution
- 🧴 Special means: for example, Topperr 3101 or Sano Refrigerator Cleaner (do not contain aggressive acids).
- 💧 Hydrogen peroxide: 3% solution for disinfecting shelves (does not leave an odor).
Procedure:
- Remove all removable elements (shelves, drawers, grates) and wash them separately in the sink.
- Apply the selected product to the walls with a soft sponge, paying attention to corners and rubber seals.
- For stubborn stains (for example, from jam or sauces), use
melamine spongebut without pressure. - Wipe all surfaces with clean water, then dry microfiber.
Pay special attention rubber seals —dirt and fungus accumulate in their folds. To clean them, a toothbrush dipped in a soda solution is suitable. After washing, apply a thin layer to the seals. silicone grease (for example, WD-40 Specialist) to prevent cracking.
4. Cleaning the external surfaces and back wall
It is enough to wipe the outside of the refrigerator 1-2 times a month with a damp cloth, but back wall (where the condenser is located) needs to be cleaned once every six months. and pet hair on the condenser grill increase energy consumption by 15-30% and can cause the compressor to overheat.
How to clean the back wall:
- Unplug the refrigerator and move it away from the wall (at least 50 cm).
- Use vacuum cleaner with a narrow attachment or a soft brush to remove dust from the condenser grill.
- Wipe the case with a damp cloth soaked in soapy water (do not pour water on the electronic modules!).
- Check
drainage handset(usually located at the bottom of the back wall) - it should not be clogged.
For built-in models (for example, Liebherr ICBN 3366) access to the rear wall is limited. In this case, use compressor for blowing dust or contact the service center.
⚠️ Attention: If your refrigerator is equipped with inverter compressor (as in Samsung RB37A5200SA), do not use metal brushes to clean the condenser - they can damage thin tubes and cause refrigerant leakage.
For stainless steel surfaces (for example, models Gorenje NRK6191MC) use special polishes, for example Weiman Stainless Steel Cleaner. They remove stains and protect against fingerprints.
5. Disinfection: how to kill bacteria and eliminate odors
Even after visual cleaning, they may remain salmonella, E. coli or moldsin the refrigerator. For complete disinfection:
- 🦠 Hydrogen peroxide: wipe all surfaces with a 3% solution, then rinse with water.
- 🍃 Essential oils: add 5 drops of tea tree oil or lavender in water for washing (have an antibacterial effect).
- 🧪 Special antiseptics: for example, Sanita Gel or Miramistin (dilute 1:10 with water).
To eliminate persistent odors:
- 🍋 Lemon juice: wipe the walls with a cut lemon slice, then rinse.
- ☕ Ground coffee: leave an open jar with coffee beans for 12 hours.
- 🧂 Salt + vinegar: prepare a slurry, apply for 10 minutes to problem areas, then rinse.
If the smell remains after all the procedures, check the drainage hole - often this is where organic matter accumulates, causing a putrefactive "aroma". For cleaning, use a syringe with warm water and soda or a special brush.
What to do if there is mold in the refrigerator?
If you find black or green spots of mold, proceed as follows:
1. Wear rubber gloves and a respirator (mold spores are dangerous to the lungs).
2. Remove visible lesions with a stiff brush soaked in a solution of vinegar or bleach (dilute 1:10 with water).
3. Wipe all surfaces undiluted hydrogen peroxide (it kills spores).
4. After cleaning, leave the door open for 24 hours to dry.
5. In the future, once a month, wipe the walls with a soda solution (1 tablespoon per 1 liter of water) for prevention.
6. Cleaning the freezer: features and lifehacks
The freezer requires a special approach - not only ice and grease accumulate here, but also frozen food crystalswhich can scratch the plastic if not carefully cleaned. Rules:
- ❄️ Do not use hot water - sudden temperature changes can damage plastic parts.
- 🧊 For washing use a soda solution or dish soap (for example, Fairy), diluted with water 1:5.
- 🧤 Wear gloves - low temperature can cause frostbite of the skin.
For cleaning freezers with the No Frost system (for example, Indesit DF 4200 W) just wipe the walls with a damp cloth - ice will not form in them. But if you notice plaque or odor, use vinegar solution (1:1 with water) for disinfection.
B freezers with manual defrosting (for example, Atlant MX-2823-06) after washing, check drain hole - it is often clogged with ice. For cleaning, use plastic spatula or warm water from a syringe.
7. fridge care after cleaning: how to prolong the effect
To keep the refrigerator clean longer, follow these rules:
- 📅 Carry out general cleaning once every 3 months (for the freezer - once every 6 months).
- 🥩 Store food in containers - this prevents splashing of grease and the spread of odors.
- 🧼 Wipe the shelves with a damp cloth once every 2 weeks (especially after spilled liquids).
- 🔌 Check the seals - if they have lost their elasticity, the refrigerator will be less able to close, and Condensation will appear inside.
For models with antibacterial coating (for example, Panasonic NR-BN30A1), it is enough to wipe the walls with damp microfiber - the special coating itself suppresses the growth of bacteria. But even in this case, once every six months it is required full disinfection.
If your refrigerator has air ionizer or carbon filter (as in Sharp SJ-FP65PMSL), do not forget to change the filter elements according to the instructions (usually every 6-12 months). A clogged filter not only stops purifying the air, but also becomes a source of odors.
FAQ: Answers to frequently asked questions
Is it possible to clean a refrigerator with a steam generator?
Yes, but with caution. The steam generator is effective for removing grease and disinfecting, but do not direct the steam jet at:
- Rubber seals (they may become deformed).
- Electronic control panels (for example, Samsung Family Hub).
- Plastic parts freezer (risk of cracking).
After steam treatment, be sure to wipe the surfaces with a dry cloth.
How to clean a refrigerator if it does not turn off (works without stopping)?
If the refrigerator does not turn off, the reason may be:
- Clogged condenser (cleaning the back wall can help).
- Faulty thermostat or temperature sensor.
- Refrigerant leak.
In this case It is not recommended to clean the refrigerator yourself it’s better to call a repairman before he arrives. you can only wipe the internal surfaces with a damp cloth without turning off the power.
How to clean refrigerator glass shelves so that there are no streaks left?
For glass shelves (for example, in Liebherr CPesf 4023) use:
- Vinegar solution (1:1 with water) + microfiber.
- Glass cleaner (Mr. Proper or Clin).
- Newspaper instead of a rag - it does not leave lint.
After washing, wipe the shelves with a dry microfiber cloth movements in a circle.
How often should you clean the drainage hole in the refrigerator?
Drainage hole (located on the back wall of the refrigerator compartment) needs to be cleaned:
- Once every 3 months - for prevention.
- Immediately after defrosting - if water has accumulated in the refrigerator.
- When an unpleasant odor appears (often the source is a clog in the drain).
For cleaning use a cotton swabmoistened in a soda solution, or a syringe with warm water.
Can I use bleach to clean the refrigerator?
Bleach (Whiteness) not recommended for several reasons:
- Chlorine vapors are toxic and can be absorbed into plastic.
- Corrodes rubber sealants.
- Leaves a persistent chemical odor that permeates products.
Instead of bleach, use hydrogen peroxide or vinegar —they are no less effective against bacteria, but are safe.
