How to clean a dirty refrigerator: 12 methods for different types of dirt

The refrigerator is the only household appliance that works 24/7, accumulating not only food, but also layers of fat, mold in the seal, yellow stains on the shelves and a persistent smell of expired food. Even if you regularly remove the expired items, microbes and fungi remain on the walls, and NoFrostsystems do not save from dust on the rear grille. The problem is that aggressive chemicals can damage plastic or rubber, and folk remedies like soda often leave stains.

In this article - detailed guide on cleaning refrigerators of all types (including Side-by-Side and built-in models) taking into account materials: from stainless steel to antibacterial coating. We tested 12 methods (from a steam generator to citric acid), compiled a table of compatibility of products with surfaces and added a checklist for general cleaning. We also figured out how to remove the smell of fish in 10 minutes and why you can’t wash the freezer with hot water.

1. Preparation: what to do before cleaning

Start with complete shutdown of the refrigerator from the network. Even if you have a model with a Holiday Mode function (for example, Liebherr CNef 4815), for deep cleaning you need to physically remove the plug. This will prevent a short circuit when moisture gets on the compressor contacts.

Next follow the algorithm:

  • 🧊 Thaw freezer (if not NoFrost). Place towels on the floor - melt water can damage the laminate.
  • 📦 Take out all the products. Throw away the spoiled ones, put the rest in a cooler bag or wrap in newspaper (the cold stays for up to 2 hours).
  • 🧽 Remove all removable elements: shelves, drawers, bars, door balconies. They are washed separately.
  • 🔍 Check the seal. If the rubber is cracked or comes off, it will have to be replaced after cleaning (article for Samsung RB37J5240SADA61-01443A).

☑️ Preparing the refrigerator for cleaning

Done: 0 / 5

⚠️ Attention: Do not place hot objects on glass shelves immediately after washing - temperature changes can cause cracks (relevant for models with shelves made of tempered glass, for example, Bosch KAN92VI30R).

2. How to clean the inside of the refrigerator: top 5 products for different contaminants

The choice of product depends on surface material and the type of contamination. For example, vinegar excellently removes limescale, but can damage the antibacterial coating BioFresh (available in refrigerators Liebherr). data-i="89">vinegar bleach kills mold, but leaves a pungent odor on the plastic.

Type of contamination Recommended product Materials for which it is suitable Materials for which it is NOT suitable
Grease, sticky stains Dishwashing gel (Fairy, AOS) Plastic, glass, stainless steel Rubber seal (dries)
Mold, black spots Hydrogen peroxide 3% or Cillit Bang Black mold Plastic, enamel Aluminium, stainless steel (may oxidize)
Yellowness, limescale Citric acid (2 tablespoons per 1 liter of water) Glass, plastic, enamel Rubber, antibacterial coatings
Smell of fish/meat Soda solution (3 tbsp per 1 liter) + activated carbon All materials
Dried drops (sauce, jam) Fine salt + damp sponge Glass, stainless steel Plastic with a soft coating

For deep disinfection use specialized means:

  • 🧴 Topperr 3101 — antibacterial spray for refrigerators (suitable for NoFrost).
  • 🧽 Sano Refrigerator Cleaner - removes odors and does not require rinsing.
  • 🍋 Natural alternative: mix water, vinegar and tea tree oil (5 drops) in a spray bottle.

3. freezer: 3 mistakes and the correct algorithm

The freezer is the most problematic place: it accumulates ice, fat from meat and fish, and a sharp temperature change during defrosting can damage the plastic. The main mistake is trying to break off the ice with a knife or fork. This scratches the coating and leads to corrosion (especially in models with an aluminum evaporator, how Indesit BIAA 13).

Correct procedure:

  1. Turn off the refrigerator and leave the freezer door open for 1-2 hours (the ice should thaw on its own).
  2. Place a tray with hot water inside the freezer - steam will speed up the process (but do not put boiling water!).
  3. Remove the melt water with a sponge, then wash the walls with a solution ammonia (1 tbsp per 1 liter of water) - it removes grease and disinfects.
  4. Wipe dry with microfiber. Moisture in the freezer leads to new icing.
What happens if you defrost with a hair dryer?

Hot air from a hair dryer can deform the plastic parts of the freezer, especially in budget models (for example, ATLANT XM 4021-000). In addition, sudden heating disrupts the operation of the thermostat, which subsequently leads to incorrect temperature maintenance.

⚠️ Attention: Never use detergents for the freezer (for example, powder cleaners; they scratch). surface, and bacteria multiply in microcracks. abrasive particles (for example, powder cleaners). They scratch the surface, and bacteria multiply in the microcracks later.

4. Cleaning the seal: how to remove mold and restore elasticity

Rubber seal is a breeding ground for mold. and the main reason cold loss (up to 30% of the energy is spent on compensating for a loose fit). If the rubber has become sticky or cracked, it must not only be washed, but also restored.

Instructions for cleaning:

  1. Wipe the seal with a damp sponge and soapy water.
  2. For mold, use miramistin or solution borax (1 tbsp per glass of water).
  3. Apply to dry rubber silicone lubricant (for example, WD-40 Specialist) - this will restore elasticity.
  4. Check the fit: place a sheet of paper between the door and the body. If it falls out, the seal needs to be replaced.

⚠️ Attention: Do not use sealants vegetable oil or vaselinefor lubrication. They attract dust and destroy over time. rubber.

5. How to clean the outside of a refrigerator: stainless steel, plastic, touch panels

External cleaning is no less important: dust on the back grille it worsens heat transfer (the compressor wears out), and fingerprints on stainless steel spoil the appearance. Different surfaces require different approaches:

  • 🔄 Stainless steel: wipe along the grain (not in a circle!) with microfiber soaked in vinegar solution (1:1 with water). For shine, use olive oil (a few drops on a napkin).
  • 🖥️ Touch panels (for example, in Samsung Family Hub): only isopropyl alcohol 70% and lint-free fabric. Water can cause a short circuit.
  • 🔌 Rear grille: vacuum cleaner with a narrow nozzle + brush for removing dust. Do not use wet cleaning - you can short the contacts!
  • 🎨 Plastic case: soap solution + toothbrush for joints. For glossy surfaces (like LG GC-B247JLVQ) suitable furniture polish.

For stubborn stains (for example, from adhesive tape) use melamine sponge, but without pressure - it erases the top layer of plastic.

6. How to remove the smell from the refrigerator: 5 express methods

If after cleaning there is a persistent smell, use these methods (tested on models with the system AirFlow and without it):

  1. Activated carbon: place 10 tablets in bowls on each shelf. Change every 3 days.
  2. Coffee beans: 50 g of beans in an open jar will absorb the smell in 12 hours.
  3. Apple cider vinegar: place a cup of vinegar on the middle shelf on night.
  4. Citrus peels: dried orange or lemon peels will freshen the air for 2-3 days.
  5. Ozonator (for example, Atmos Venta-150): treat the refrigerator within 10 minutes - will kill all bacteria and odors.

For prevention place on the bottom of the refrigerator baking soda in an open package (change once a month). And if the smell appears after defrosting, check drainage hole - rotting organic matter often accumulates there.

7. Cleaning the NoFrost system: why it is needed and how to do it

Refrigerators with NoFrost (for example, Beko GNE114620X) do not require defrosting, but this does not mean that they do not need to be cleaned. Air circulates in the system, and dust, grease and even mold accumulate on the evaporator (hidden behind the rear panel). This leads to:

  • ❄️ Freezing of the evaporator (the refrigerator begins to hum and freezes poorly).
  • 🦠 Bacterial proliferation —the air distributes them throughout all products.
  • 🔥 Overheating of the compressor (electricity consumption increases).

How to clean NoFrost:

  1. Turn off the refrigerator, remove the back panel in the freezer (usually it is secured with latches).
  2. Using a vacuum cleaner remove dust from the evaporator (it looks like a radiator).
  3. Wipe the fan blades with a damp cloth (do not allow water to enter!).
  4. Rinse the drainage hole with a syringe with a soapy solution.
How often to clean NoFrost?

Recommended frequency - once every 6 months. But if the refrigerator is in a kitchen with high humidity (for example, next to the stove), clean it every 3 months. Signs that it’s time to clean up: there is an odor, the compressor runs non-stop, frost quickly forms on the food.

8. General cleaning: step-by-step plan for 1 hour

If the refrigerator has not been washed for more than six months, use this algorithm for comprehensive cleaning (suitable for all types, including Side-by-Side and two-chamber models):

  1. Defrosting (if needed) - 30-60 minutes.
  2. Removable parts: soak the shelves and drawers in a bath of hot water and soda (50 g per 5 l). For stubborn stains, use melamine sponge.
  3. Inner walls: wash from top to bottom with a solution of vinegar (1:1), then with clean water. Pay attention drainage hole to clean it with a cotton swab.
  4. Sealant: treat with hydrogen peroxide, lubricate with silicone lubricant.
  5. Rear grille: vacuum, wipe with a dry cloth.
  6. Outer body: for stainless steel - a special polish, for plastic - soap solution.
  7. Disinfection: place activated carbon tablets or citrus peels on the shelves.
  8. Drying: leave the door open for 1-2 hours, then turn on the refrigerator.

⚠️ Attention: If the refrigerator does not turn on after cleaning, check whether water has entered the thermostat (usually located next to the lamp). Dry it with a hair dryer at minimum power.

FAQ: Frequently asked questions about cleaning the refrigerator

Can I wash the refrigerator with bleach?

Chlorine kills mold and bacteria, but has 3 disadvantages: a pungent odor (absorbed into plastic), corrodes the rubber of the seal and can oxidize metal parts. It’s better to use hydrogen peroxide or specialized products like Sano Refrigerator Cleaner.

How often should you wash the refrigerator?

Optimal frequency - every 1-2 months (unscheduled - if juices spilled or an odor appeared). It is enough to clean the freezer once every 3-4 months, and the system NoFrost - once every six months. If there are allergy sufferers in the house, cleaning is carried out more often.

How to wash yellow stains on plastic?

Yellowness appears due to oxidation of plastic or exposure to fat. The paste from baking soda and water (1:1) or toothpaste with a whitening effectwill help remove it. Apply for 10 minutes, then wipe with a damp sponge. For old stains, use retinol alcohol (sold in pharmacies).

Can I use steam generator for cleaning the refrigerator?

The steam generator is effective for disinfection and removal of grease, but is not suitable for all models. It is possible use for plastic and glass surfaces, It is not possible for seals (hot steam deforms it) and electronic panels. The optimal distance to the surface is 15–20 cm, the steam temperature is not higher than 100°C.

Why did the refrigerator become worse after washing freeze?

Probable reasons:

  1. Water got on thermostat or temperature sensor (needs to dry).
  2. During cleaning, moved door hinges - check the tight fit.
  3. Clogged drain hole (in models with drip system).
  4. Too much ice on the evaporator (NoFrost) - defrosting is required.

If the problem persists, call a technician - it may be damaged freon line.
