The refrigerator is the only household appliance that works 24/7, accumulating not only food inside, but also persistent odors, greasy stains, and sometimes mold or bacteria. Even regular washing of shelves with detergent does not always help: after a week, a musty “aroma” may appear, and plastic parts will turn yellow over time. In this article we will look at how to wash the refrigerator inside and outside, remove the smell for a long time, and also tell you what mistakes lead to re-contamination. 15 proven methods clean the refrigerator inside and out, remove the smell for a long time, and also tell you what mistakes lead to re-contamination.
We will pay special attention to drip refrigerators - they have different “weak points”: in the first, dirt accumulates in the drainage hole and on the rear wall, and in the second - in the condensate tray. You will also learn how NoFrost systems and drip refrigerators - they have different “weak points”: in the first, dirt accumulates in the drainage hole and on the back wall, and in the second - in the condensate tray. You will also learn how safely clean the rubber seal (its damage is the main reason for icing of the chamber) and what home remedies that corrode the plastic of refrigerators Samsung, LG i Indesit for 1-2 cleanings.
Preparation: what needs to be done before cleaning
Before grabbing a sponge, follow 4 mandatory steps - this will save time and protect equipment from damage:
Defrost the refrigerator (even if you have NoFrost|Remove all food and shelves|Unplug from the outlet|Prepare warm water and products-->
If your refrigerator is with NoFrost, you still need to defrost it once every 6-12 months. The fan and evaporator become clogged with dust, and the drainage hole becomes clogged with grease, which leads to increased energy consumption an unpleasant odor. For drip models (Indesit C168NF, ATLANT XM 4021-000), defrosting is required when ice is thicker than 5 mm - otherwise the compressor will wear out.
It is important to remove correctly shelves and containers. Most refrigerators (Bosch KAN90VIFP, Liebherr CPes 4066) have glass shelves fixed with plastic latches - do not pull them up, but first slide them back, then lift them. For models with TwistIceMaker (for example, Samsung RB37J5240SS), before cleaning, the ice maker must be turned off through the menu or the ice tray must be removed.
⚠️ Attention: Do not use a hairdryer or hot water for defrosting - this will deform the rubber seal. Maximum water temperature for washing internal surfaces: 40–45°C.
What you should not wash a refrigerator with: 5 dangerous products
Some “folk” cleaning methods lead to destruction of plasticcorrosion of metal parts or damage to the seal. Here's what is strictly prohibited:
- 🧼 Chlorine-containing bleaches (for example, “Whiteness”): they corrode the sealing gum and leave a toxic odor that is absorbed into the products.
- 🔥 Abrasive powders (soda in dry form, "Pemolux"): scratch glass and plastic, creating microcracks for bacteria.
- 🧴 Concentrated acids (acetic essence 70%, citric acid in crystals): destroy the antibacterial coating of shelves (for example, u Liebherr s technology
BioFresh). - 🧽 Dishwasher detergents ("Finish" tablets): contain aggressive surfactants that foam and are difficult to wash off.
- 🛢️ Solvents and acetone: melt the plastic of door handles and control panels (especially for refrigerators with display).
Also avoid hard sponges metal scrapers - they damage the internal coating. For stubborn stains, use silicone spatulas or soft brushes (for example, dental).

Top 5 means for cleaning the inside of the refrigerator
The choice of product depends on the type of contamination and the material of the internal surfaces. For NoFrost-models (Samsung RB38T602CS9, LG GA-B459SLGL) liquid formulations without abrasives are suitable, and for drip (ATLANT MXM 1705-80) - products with an antibacterial effect.
| Type of contamination | Recommended product | How to use | Pros | Cons |
|---|---|---|---|---|
| Grease stains, sticky residue | Dishwashing gel (Fairy, AOS) | 1 cap per 1 liter of warm water | Quickly removes grease, does not leave streaks | Requires careful rinsing |
| Musty smell, mold | Hydrogen peroxide 3% | Apply for 10 minutes, then wipe with a damp sponge | Kills bacteria, whitens yellow spots | Can discolor colored stickers |
| Dried drops, food deposits | Baking soda (2 tbsp per 500 ml of water) | Apply the paste for 15 minutes, then rinse off | Safe for all surfaces, neutralizes odors | Requires mechanical friction |
| Complex stains (blood, berry juice) | Special spray (Topperr 3104, Sano Refrigerator Cleaner) | Spray, wait 5 minutes, wipe with a napkin | Fast-acting, antibacterial effect | High price (from 300 rubles) |
| General disinfection | Vinegar 9% (1:1 with water) | Wipe all surfaces, then with water | Kills 99% of bacteria, removes limescale | Pungent odor, requires ventilation |
For freezer better to use alcohol solutions (vodka or medical alcohol diluted 1:1 with water) - they do not freeze and quickly evaporate without leaving streaks. But essential oils (tea tree, lavender) will add a pleasant aroma, but will not eliminate the cause of the smell.
How to wash sealing rubber: 3 ways
Sealing rubber is the main “sore spot” of any refrigerator. Crumbs, grease and bacteria accumulate in its folds, which become a source of unpleasant odor. To clean the rubber, follow these methods: without. damage, follow these methods:
- Toothbrush + soda
Mix soda with water to form a paste, apply to the brush and carefully clean all the folds. To disinfect, then wipe the elastic band with hydrogen peroxide.
- Ammonia
Dilute 1 tbsp of ammonia in 1 liter of water, dampen a rag and wipe the seal. This method kills bacteria and restores elasticity to the elastic.
- Silicone grease
After cleaning, apply a thin layer to the dry elastic. data-i="148">(for example, silicone grease (For example, WD-40 Specialist). This will prevent cracking and extend the life of the seal.
If the rubber is detached from the body, it can be temporarily fixed double-sided tape or moment glue, but it is better to replace the seal - its cost for popular models (Samsung RL38TDCAS, ATLANT MHM 1842-90) does not exceed 1,500 rubles.
⚠️ Attention: Do not use gum for cleaning vegetable oil —it goes rancid and increases the smell. Also avoid vaseline: it attracts dust and over time destroys the rubber structure.
How to remove the smell from the refrigerator: 7 working methods
Even after thorough washing, the smell may remain if bacteria penetrated into microcracks in plastic or the drainage system. Here's what really helps:
- ☕ Activated carbon: Place 10-15 tablets in small containers on each shelf. Change every 2 weeks.
- 🍋 Citrus peels: dried lemon or orange peels absorb odors and freshen the air.
- 🧂 Salt in bags: pour salt into cloth bags and place in the corners of the refrigerator. Absorbs moisture and odors.
- 🧊 Frozen vinegar: pour 9% vinegar into ice molds and place in the freezer for 12 hours, then ventilate.
- 🌿 Soda + essential oil: mix 2 tbsp. l. soda with 5 drops of tea tree oil, scatter on a saucer.
- 🧪 Ozone generator: if the smell is persistent, use a household ozonizer (for example, AirComfort XJ-3000) for 30 minutes.
- 🧻 Newspapers: place crumpled newspapers on shelves - they will absorb the smell in 1-2 days.
For drainage hole (at the bottom of the back wall) use a syringe with a soda solution (1 hour. l. per 100 ml of water). Rinse the hole once a month - this will prevent blockages and unpleasant odor from stagnant water.
What to do if the smell returns after a week?
If the smell appears again, the problem lies deeper: perhaps the drainage tube is clogged or bacteria have settled in the refrigerator in hard-to-reach places (for example, under plastic linings). In this case:
1. Check the drainage hole - clean it with a wire or a toothpick.
2. Fill the tube with a solution of vinegar (1:1 with water) using a syringe.
3. If the smell remains, call a technician to diagnose the system NoFrost (the filter may need to be replaced or the fan needs to be cleaned).
Cleaning the freezer: features and life hacks
The freezer requires a special approach: hot water cannot be used here (risk of cracks in the plastic), and ice and plaque are removed longer. Here is a step-by-step algorithm:
Unplug the refrigerator|Wait for complete defrosting (8-12 hours)|Remove the ice with a plastic spatula|Rinse the shelves and walls with ammonia solution (1 tablespoon per 1 liter of water)|Wipe dry with a microfiber cloth|Turn on the refrigerator and let it run empty for 1 hour-->
For accelerated defrosting put a pan of hot water (not boiling water!) in the freezer and close the door for 20 minutes. The steam will dissolve the ice, making it easier to remove. Do not use a knife or fork - this will damage evaporator and lead to freon leakage.
If yellow coatingappears in the freezer, this is a sign metal oxidation. Remove it with a mixture of lemon juice and salt (1:1), then wipe the surface glycerin - this will restore the protective layer.
⚠️ Attention: After cleaning the freezer Do not turn on the refrigerator immediately. Let it sit for 30-60 minutes at room temperature - this will prevent the compressor from overloading.
Cleaning external surfaces: doors, handles, display
The external parts of the refrigerator also need care. Dust on condenser (rear grille) increases energy consumption by 15–20%, and dirty handles are a breeding ground for bacteria. Here's how to properly wash:
- 🔄 Stainless steel door: wipe with a solution of vinegar (1:1 with water), then polish with a dry cloth along the metal fibers.
- 🖥️ Display and control panel: use alcohol wipes or special products for electronics (Kärcher Display Cleaner).
- 🔗 Rubber handles: wash with soapy water, then apply silicone grease to protect against cracking.
- 🔥 Condenser (rear grille): vacuum or wipe with a dry brush. Do not use water!
- 🧲 Magnetic holders: remove them from the front. washing the door - water gets under the magnets and causes rust.
For refrigerators with a water dispenser (Samsung RF23J9011SG, LG GR-B247JVQA), be sure to clean the water supply tube once every 3 months. Pour a solution of citric acid into the system (1 tsp per 200 ml of water) and pass through the dispenser.
FAQ: Frequently asked questions about cleaning the refrigerator
Is it possible to wash the refrigerator without unplugging it?
No, it’s dangerous! Even if you only wash the shelves, moisture can get on the electrical contacts or display. Always unplug the refrigerator from the outlet before cleaning.
How often should you wash the refrigerator?
Optimal frequency:
- General cleaning (shelves, walls, seal) — every 1–2 months.
- Cleaning the drainage hole — every 3 months.
- Washing the condenser — every 6 months.
- Defrosting (for NoFrost) — once a year.
If raw meat/fish are stored in the refrigerator, wash immediately after removing the products.
How to clean the refrigerator from green stuff or iodine?
Green green and iodine is removed hydrogen peroxide 3% or Antipyatin rescuerApply the product to a cotton pad, apply to the stain for 5-10 minutes, then wipe with a damp sponge. For persistent stains, repeat the procedure 2-3 times.
Why does the refrigerator freeze more strongly after washing?
This happens due to:
- Moisture on thermostat or temperature sensor (need to dry for 1-2 hours).
- Damage to the sealing rubber (check its tightness).
- Clogged drainage hole (no water goes away, the compressor works without stopping).
If the problem does not disappear after a day, call a technician for diagnostics.
Is it possible to use a steam generator to clean the refrigerator?
Yes, but with caution:
- The steam temperature should not exceed 100°C.
- Keep the nozzle at a distance 15–20 cm from surfaces.
- Do not direct steam at seal, display and plastic parts.
- After treatment, wipe all surfaces with a dry cloth.
The steam generator removes grease well and disinfects, but is not suitable for NoFrost-models with an open evaporator.
