The refrigerator is the only household appliance that works without interruption 24/7, accumulating inside not only food, but also bacteria, mold, and grease stains. Even if it looks clean on the outside, germs can grow in the nooks and crannies of the drain hole or under the rubber seal, causing an unpleasant odor. Regular washing not only extends the life of equipment, but also protects your health: according to Rospotrebnadzor, up to 60% of food poisoning are associated with poor hygiene during food storage.
In this article you will find step-by-step instructions on washing the refrigerator, taking into account its type (NoFrost, drip, with a freshness zone), a list allowed and prohibited products, as well as tips for eliminating persistent odors. We’ll separately look at how to properly dry cameras, clean the drainage hole and care for external surfaces - including stainless steel and touch panels. If you have never defrosted a refrigerator or are afraid of damaging your appliances, here are the answers to all your questions.
Why you can’t wash the refrigerator “at random”
Many limit themselves to wiping the shelves with damp a rag once a month, but this is not enough. An ideal environment for the growth of bacteria is created inside the refrigerator: temperature +4...+8°C and high humidity. For example, Listeria monocytogenes (the causative agent of listeriosis) can survive at +4°C up to 10 days, and mold fungi germinate in the drainage hole within a week after organic residues get there.
Improper washing is fraught with:
- 🔥 Damage to equipment: aggressive agents (for example, bleach or abrasive powders) destroy the sealing rubber and coating of shelves, leading to leakage of freon or corrosion.
- 🤢 Food poisoning: if you do not wash the drainage hole, mucus with pathogens accumulates there microorganisms that then get on the products.
- 💨 Persistent odor: fats and proteins (for example, from milk or fish) are absorbed into the plastic, and ordinary water does not remove them.
- ⚡ Damage to electronics: moisture getting on the display or the fan NoFrost-system can cause a short circuit.
You need to be especially careful with models Samsung Family Hub, LG InstaView or Bosch VitaFresh —they have touch panels and complex ventilation systems that are easy to damage. For example, in refrigerators with a function Metal Cooling (like Liebherr), you cannot use products with ammonia: they oxidize metal surfaces.
What can and cannot be used to wash the refrigerator: table of safe products
The choice of detergent depends on the material of the internal surfaces and the type of contamination. For example, for glass shelves even a weak vinegar solution is suitable, but plastic containers the freshness zone cannot be treated with alcohol - it makes the plastic brittle. Below is a table with proven options:
| Surface type | Permitted means | Prohibited means | Notes |
|---|---|---|---|
| Plastic (shelves, drawers, seal) | Soda (2 tablespoons per 1 liter of water), laundry soap, baby bottle cleaner | Bleach, acetone, gasoline, abrasive powders | After soda, be sure to rinse - it leaves a white residue |
| Glass | Vinegar (1:1 with water), alcohol (70%), special sprays for refrigerators (Topperr, Unicum) | Hard brushes, metal sponges | For stubborn stains, use melamine sponge |
| Stainless steel (external panels) | Stainless steel products (Electrolux Stainless Steel Cleaner), olive oil (for polishing) | Bleaches, chlorine products, rough brushes | Wipe in the direction of the “fibers” of the metal |
| Rubber (sealant) | Hydrogen peroxide (3%), washing gel dishes | Solvents, acids, silicone lubricants | After washing, lubricate with glycerin or petroleum jelly |
| Drainage hole | Soda + water (thick paste), cotton wool sticks, Mole (diluted) | Needles, toothpicks, sharp objects | Rinse with warm water under pressure |
Critical: never use for cleaning the refrigerator with products containing fragrances (for example, shower gel or air freshener). Their particles remain on surfaces and are absorbed into products, changing their taste.
⚠️ Attention: If your refrigerator is equipped with a system Air MultiFlow (like Samsung) or Twin Cooling (LG, Avoid getting moisture into the ventilation openings. This can disrupt air circulation and lead to icing of the evaporator.
Preparing for washing: 5 mandatory steps
Before you start cleaning, the refrigerator must be properly prepared. This will protect you from breakdowns and save time. Let's start with the most important thing - defrosting (if you don't have NoFrost). In models with a drip system (Indesit, Atlant), the ice on the back wall melts on its own, but up to 5–7 mm of ice can accumulate in the freezer compartment, which will have to be removed manually.
Disconnect from the mains (remove the plug from sockets)|
Take out all the products and put them in a cooler bag or a basin with ice|
Take out all removable elements (shelves, drawers, grates)|
Place a tray to collect melt water (if there is ice)|
Check the temperature in the room (must be at least +15°C, otherwise the condensation will not evaporate)-->
If the refrigerator with a system NoFrost (Bosch, Siemens, Liebherr, you do not need to defrost it - just turn it off for 1-2 hours to ventilate. But there is a nuance: in some models (for example, Samsung RB37J5240), even with NoFrost frost may form on the bottom of the freezer - you will have to remove it with a plastic scraper.
With products, do this:
- ❄️ Meat, fish, dairy products in thermal bag or wrap in newspaper and place in a bowl filled with ice.
- 🥬 Vegetables and fruits can be left at room temperature for 1-2 hours (except for greens - they will wither).
- 🧊 Transfer the ice from the freezer into bags and use it to cool food.
⚠️ Attention: Do not place the refrigerator in the sink on a hot day (above +25°C). A sudden change in temperature can cause condensation inside the walls, which will lead to corrosion of metal parts. The optimal temperature for cleaning is +18…+22°C.
Step-by-step instructions: how to wash the inside of the refrigerator
Let's start with main chamber. The main thing here is not to miss the “risk zones”: the rubber seal, the drainage hole and the back wall (in drip models). Use two buckets: one with a cleaning solution, the second with clean water for rinsing.
Step 1. Removable elements
Shelves, drawers and wash the grates separately in the sink or bathtub. To do this:
- Soak them in warm water with soda (2 tablespoons per 5 liters) for 10-15 minutes.
- Wipe with a sponge with a soft side, paying attention to the grooves and corners.
- Rinse under running water and wipe dry microfiber.
Step 2. The walls and bottom of the chamber
Use soft sponge or microfiber cloth. Start on the top shelves and work your way down. For stubborn stains:
- 🧽 Grease: apply a paste of baking soda and water, leave for 5 minutes, then rinse.
- 🍷 Wine or juice: wipe with hydrogen peroxide (3%).
- 🧀 Musty smell: treat with a solution of vinegar (1:1 with water).
Step 3. Sealing rubber
This is the most dirty place: crumbs, sticky residue and mold accumulate here. To clean:
- Wipe the elastic band with a cotton swab dipped in hydrogen peroxide.
- For hard-to-reach places, use
a toothpick with cotton wool. - After washing, lubricate sealant food-grade Vaseline (sold at the pharmacy) - this will prevent cracking.
Step 4. Drainage hole
If it is not cleaned, water will accumulate at the bottom of the chamber and then appear unpleasant smell. How to clean:
- Take
a cotton swab or a syringe without a needle. - Rinse the hole with warm water and soda (1 tsp per glass).
- Blow it out (you can use your mouth or a hair dryer in the cold air).
Step 5. Freezer
The main thing here is do not use hot waternot to damage the plastic. To remove ice:
- ❄️ Place a bowl of hot water (not boiling water!) in the freezer and close the door for 10 minutes - the ice will thaw faster.
- 🧊 Scrape off the deposits plastic scraper (not metal!).
- 🧹 Remove dust on the back wall with a vacuum cleaner with a narrow nozzle.
How to wash the outside of the refrigerator: stainless steel, plastic, touch panels
It is enough to wipe the outer surface of the refrigerator once every 1–2 weeks, but general cleaning (including cleaning the back wall and legs) should be done once every 3–6 months. Pay special attention to:
- 🔄 Handles: up to 80% of bacteria hands accumulate on them.
- ⚡ Display (if any): do not use alcohol - it corrodes the anti-reflective coating.
- 🔌 Back wall: dust accumulates here, which impairs heat transfer and increases energy consumption.
Instructions for materials:
Stainless steel (Samsung, LG, Gorenje):
- Wipe the surface with damp microfiber in the direction of the “fibers” of the metal.
- To remove stains, use special spray (for example, Weiman Stainless Steel Cleaner) or olive oil (a few drops on napkin).
- Do not press hard - stainless steel is soft and can be scratched.
Plastic (Atlant, Indesit, Beko):
Just wipe soap solution (1 tsp liquid soap per 1 liter of water). For glossy surfaces, use furniture polish - this will restore shine.
Touch panels (Samsung Family Hub, LG InstaView):
Unplug the refrigerator. Wipe the panel dry microfibermoistened in distilled water. For stubborn stains, use isopropyl alcohol (70%)but not ethanol!
Back wall and condenser:
Dust on capacitor (grid at the back) increases electricity consumption by 15–20%. To clean:
- Move the refrigerator away from the wall (carefully so as not to damage the floor!).
- Use a vacuum cleaner with a narrow attachment to remove dust from the grille.
- Wipe the back wall with a damp cloth, then dry.
How to get rid of an unpleasant smell in the refrigerator
If the smell remains after washing, the problem lies deeper: in the drainage system, seal or plastic parts that have absorbed fats. Here 5 proven ways eliminate it:
1. Baking soda
Place an open box of baking soda on the middle shelf (or pour 2 tablespoons into a saucer). Baking soda absorbs odors by neutralizing acids. Change it every 1–2 months.
2. Activated carbon
Crush 10 tablets of carbon, put in a gauze bag and place in the refrigerator for a day. Coal adsorbs not only odors, but also harmful gases (for example, ammonia from spoiled foods).
3. Lemon or vinegar
Wipe all surfaces with a solution of vinegar (1:1 with water) or lemon juice. The acid kills odor-causing bacteria. Leave the lemon slices in a small container for 12 hours.
4. Coffee or tea
Pour dry tea (preferably green) or coffee beans into a saucer. They will absorb odors in 1-2 days. This method is not suitable if dairy products are stored in the refrigerator - they can absorb the aroma.
5. Special absorbers
Odor absorbers for refrigerators are sold in household chemical stores (for example, Air Wick, Bref). They work on the basis of zeolite or activated carbon. They are more expensive than folk remedies, but last longer (up to 3 months).
What to do if the smell returns?
If the smell appears again after 1-2 weeks, the problem may be drain tube or evaporator. In this case:
1. Unplug the refrigerator and defrost it for 12–24 hours.
2. Rinse the drainage hole with a solution Mole (diluted with water 1:10).
3. Wipe the back wall (in drip models) with a vinegar solution.
If this does not help, contact service - the seal may need to be replaced or the ventilation needs to be cleaned.
How often should you wash the refrigerator: cleaning schedule
The frequency of washing depends on the type of refrigerator, the number of users and the types of stored products. Here is the optimal schedule:
| Element | Cleaning frequency | Reasons |
|---|---|---|
| Internal shelves and drawers | Once every 1-2 weeks | Crumbs, grease, bacteria from products accumulate |
| Sealing rubber | Once a month | Mold and dirt reduce the tightness |
| Drainage hole | Once every 3 months | Clogging leads to water accumulation and odor |
| Rear wall and condenser | Once every 6 months | Dust increases energy consumption |
| General washing (defrosting, washing all surfaces) | Once every 3–6 months | Removal of stubborn dirt and disinfection |
If your family has allergies or small children, wash the refrigerator more often (once every 3-4 weeks), as they are more sensitive to bacteria. Also increase the frequency of cleaning if:
- 🐟 Store a lot of fish or seafood.
- 🧀 Keep cheeses with a strong smell (Dorblue, Limburger) in the refrigerator.
- 🌿 You often cook dishes with garlic, onions or spices.
⚠️ Attention: In refrigerators with a NoFrost (Bosch, Liebherr) system, ice does not form, but this does not mean that they can not be washed. The ventilation ducts of such models require regular cleaning of dust (once every 6 months), otherwise air circulation will be disrupted.
Common mistakes when washing a refrigerator
Even experienced housewives sometimes make mistakes that lead to breakdowns or deterioration of hygiene. Here TOP-7 misconceptions:
1. Using hot water
Hot water (above +40°C) deforms plastic parts and can damage the seal. The optimal water temperature is +25…+35°C.
2. Washing a refrigerator that is turned on
This is dangerous not only due to electric shock, but also due to a short circuit if water gets on the electrical contacts. Always unplug the equipment!
3. The use of abrasive agents
Powders with grains (such as Pemolux) scratch glass and plastic, creating microcracks where bacteria then accumulate.
4. Ignoring the drainage hole
If you don't clean it, water will accumulate at the bottom, and then mold will appear. In advanced cases, this leads to corrosion of metal parts.
5. Drying in a draft
If you leave the door open in a ventilated area, the seal may dry out and crack. It is better to wipe the surfaces dry with microfiber.
6. Storing food during washing
Many people put food in the sink or on the balcony, but this disrupts the temperature regime. Use thermal bag or a bowl of ice.
7. Neglect of external cleaning
Dust on the condenser increases the load on the compressor, which reduces the life of the refrigerator by 20–30%.
FAQ: Answers to frequently asked questions
Is it possible to wash a refrigerator with a steam generator?
Yes, but with caution. The steam generator is effective for disinfection, but:
- Do not direct the steam jet at seal —it may become deformed.
- Do not use steam for freezer compartment —sharp drop temperatures are harmful to plastic.
- After treatment, wipe the surfaces with a dry cloth to remove condensation.
It is better to use a steam generator for removable shelves and drawers, and not for the walls of the refrigerator.
How to wash a refrigerator with the NoFrost system?
NoFrost does not mean that the refrigerator does not need to be washed. Cleaning features:
- Defrosting is not required, but unplug for 1-2 hours it is necessary for ventilation.
- Clean the ventilation holes a cotton swab, soaked in a soapy solution.
- Do not use sharp objects to remove ice in the freezer - only a plastic scraper.
In models with Twin Cooling (LG), wash both chambers separately so as not to upset the balance temperatures.
How to wash the inside of the refrigerator to avoid streaks?
Stains remain due to hard water or improper rinsing. To avoid them:
- Use distilled or filtered water for rinsing.
- Wipe surfaces dry microfiber immediately after washing.
- For glass, use spray for windows (without ammonia!) or a vinegar solution (1:1 with water).
Can I use bleach for washing refrigerator?
No! Bleach (including Whiteness) contains chlorine, which:
- Destroys the rubber seal.
- Reacts with metal parts, causing corrosion.
- Leaves toxic fumes that are absorbed into foods.
Replace bleach with hydrogen peroxide (3%) or baking soda.
How to quickly defrost a refrigerator before washing?
If time is short, this will help speed up the process:
- 🧊 Place a pan of hot water (not boiling water!) in the chamber and close the door for 10-15 minutes.
- 💨 Point at ice fan - cold air will speed up the melting.
- 🧻 Place on shelves paper towels - they will absorb melt water.
Do not use a hairdryer or heater - this is dangerous for the plastic and can damage the seal!
