The refrigerator is the only household appliance that works around the clock, accumulating not only food, but also persistent dirt. Even with regular cleaning, a sticky coating from sauces, yellow discoloration from vegetables, and mold or an unpleasant odor form in the nooks and crannies of the walls. Errors during cleaning (for example, using abrasives on know frost or aggressive chemicals on rubber seals) can lead to equipment breakdown or damage to surfaces.
In this article - current methods for 2026 to clean the inside of the refrigerator, tested on models Samsung RB30A3200SA, LG GA-B409SLGL, ATLANT XM 4021-000 and others. We will look at what products are safe for plastic, stainless steel and glass shelves, how to remove the smell of fish or onions in 10 minutes, and why you should not wash your refrigerator with hot water. Separately - instructions for systems No Frost and drip defrosting.
Preparing the refrigerator for cleaning: 5 mandatory steps
Before grabbing a sponge, follow these steps - they will save time and protect equipment:
- 🔌 Turn off the power. It is not enough to pull the plug - press the defrost button (if there is one) or turn off the machine on the panel. This will prevent power surges when turned on after cleaning.
- 🥬 Take out all the products. Place them in a cooler bag or wrap them in towels soaked in ice water (this will keep them warm longer).
- 🧊 Let the ice thaw. If more than 5 mm of ice has accumulated in the freezer, do not try to scrape it off - use
defrost modeor leave the door open for 1-2 hours. - 🧽 Remove all removable elements. Remove shelves, containers, grates and drawers and wash separately (the cleaning method depends on the material - more on this below).
- 📏 Check the seals. If the rubber is cracked or comes off, after cleaning, lubricate it. water on the ventilation holes in the rear wall. Moisture may damage the fan or defrost sensor. silicone grease (For example, WD-40 Specialist).
⚠️ Attention: If your refrigerator has a system No Frost, never direct the water jet towards the ventilation holes in the rear wall. Moisture may damage the fan or defrost sensor.
What you should not wash the refrigerator with: 7 prohibited products
Some “folk” methods and household chemicals can ruin the coating or leave toxic residues Avoid:
| Means | Why it is dangerous | What to replace |
|---|---|---|
| Chlorine (White) | Corrodes plastic, leaves a persistent chemical odor that is absorbed into products. | Hydrogen peroxide 3% |
| Vinegar essence (70%) | It spoils the antibacterial coating and can cause corrosion of metal parts. | Table vinegar 9% (diluted 1:1) |
| Soda in dry form | Scratches glass and glossy plastic, gets clogged in the cracks of seals. | Soda solution (2 tablespoons per 1 liter of water) |
| Dishwashing liquid (Fairy, AOS) | Forms a film that attracts dust and grease, enhances odors. | Special product for refrigerators (Topperr 3104) |
| Melamine sponge | Erases the factory coating, makes the plastic dull. | Soft microfiber or silicone brush |
⚠️ Attention: If you clean the refrigerator with ionic silver (for example, models Sharp SJ-FP66PVSL or Panasonic NR-BN30A1), do not use products with acids (lemon, vinegar) - they neutralize antibacterial effect of the coating.
Top 5 safe products for cleaning the refrigerator
The choice of product depends on the type of contamination and material of the surfaces:
- 🍋 Lemon solution (juice of 1 lemon + 1 liter of water). Kills bacteria, removes limescale and refreshes the smell. Suitable for all types of coatings except matte plastic (can discolor).
- 🧂 Saline solution (2 tablespoons of salt + 1 liter of hot water). Effective against grease and yellowness on glass shelves. After use, be sure to rinse the surface with clean water.
- 🧴 Special sprays (Electrolux E6RCS104, Bork K801. Contains antibacterial components and does not require rinsing. data-i="122">Special sprays No Frost.
- ☕ Coffee grounds. Absorbs odors better than activated carbon. Place the dry grounds in bowls on the shelves for 12 hours, then vacuum.
- 🧼 Laundry soap 72%. on a grater, dissolve in warm water (1:10). Suitable for general cleaning, but requires careful rinsing.
For stainless steel use alcohol solution (1:1 with water) - it removes stains and fingerprints. Apply along the grain of the metal (usually vertically).
☑️ Checklist for cleaning the refrigerator
How to clean a refrigerator from mold and black spots
Mold appears in places where moisture accumulates: under vegetable drawers, on rubber seals and in the drainage hole. To remove it forever:
Prepare a solution: 1 tsp tea tree oil + 1 tbsp. baking soda data-i="147">Treat the affected areas + 1 liter of warm water. This is a natural antiseptic, safe for products.
Treat affected areas with a toothbrush (for hard-to-reach places) or with a cotton swab (for seals).
Leave solution for 15 minutes, then rinse with clean water.
Dry the refrigerator hairdryer (cold mode) or leave the door open for 2-3 hours.
⚠️ Attention: If mold appears in the drainage hole (small hole behind the refrigerator), clean it using a syringe with warm water or wire. Clogged drainage leads to water accumulation under the drawers and corrosion.
For prevention, wipe the seals once a month with a 9% vinegar solution (1:1 with water) - this will prevent the growth of fungus.
What to do if there is mold returned?
If mold appears again after cleaning, check:
- The tightness of the seals (attach a piece of paper to the closed door - if it falls out, a replacement is needed).
- The temperature in the refrigerator (optimally +4°C, at +8°C and above mold multiplies more active).
- Ventilation (do not place the refrigerator close to the wall, leave a gap of 5-10 cm).
How to remove persistent odors: fish, onions, rotten meat
Odors are absorbed into plastic and rubber, so ordinary washing is not enough. Effective methods:
- 🍎 Apple cider vinegar. Wipe all surfaces with undiluted vinegar, then rinse after 30 minutes. Even neutralizes the smell of rotten fish.
- 🥛 Milk. Place an open container of milk in the refrigerator for 12 hours - it will absorb extraneous aromas.
- 🧃 Carbonated water (Sprite, 7UP). Pour into a bowl and leave overnight. Carbon dioxide destroys odor molecules.
- 🌿 Activated carbon. Place tablets on the shelves (10 pieces per chamber) or use carbon filter for refrigerators (Zepter BioFresh).
For emergency odor removal onion or garlic wipe walls potassium permanganate solution (pale pink!) - it oxidizes sulfur compounds that cause an unpleasant odor.
⚠️ Attention: If the smell remains after all procedures, check evaporator (back wall in models with a drip system). Sometimes rot accumulates there - professional cleaning will be required.
Cleaning removable elements: shelves, drawers, seals
Shelves and containers are washed separately, but the methods depend on the material:
| Material | How to wash | What not to do |
|---|---|---|
| Glass | Soap solution or glass cleaner (Mr. ProperFor limescale - vinegar 9%. | Abrasive powders, metal. sponges. |
| Plastic (matte) | Warm water with liquid soap. For yellowness - a paste of soda and water (1:1). | Hot water (deforms), bleach. |
| Plastic (glossy) | Spray for plastic (Pledge) or ammonia solution (1 tbsp per 1 liter of water). | Brushes, melamine sponge. |
| Rubber (seals) | A damp cloth with Lysol or hydrogen peroxide. After cleaning, lubricate with vaseline. | Solvents, acetone. |
For boxes with microcracks (where dirt accumulates) use toothbrush with a paste of soda. After washing, rinse them boiled water - this will remove any remaining detergent.
⚠️ Attention: If cracks appear on plastic shelves, do not use them for storing liquid products (soups, milk) - bacteria will penetrate into the pores of the material.
Features of cleaning No Frost refrigerators and drip models
The defrosting system determines exactly how you will wash the refrigerator:
- ❄️ No Frost:
- Do not direct water onto the ventilation grilles (risk of short circuit).
- Use dry cleaning (microfiber cloths) or sprays without flushing (Sano Refrigerator Cleaner).
- Once every six months, vacuum the back wall (dust accumulates there and clogs the filter).
- 💧 Drip system:
- You can wash the walls with a damp sponge, but avoid getting water into the
drainage hole.- After cleaning, wipe the back wall dry - this will speed up the formation of ice during the next cycle.
- If ice builds up faster than usual, check thermostat (may need adjustment).
For models with freshness zone (for example, Liebherr CNesf 4355) use special napkins with silver ions —they do not disturb the microclimate in the compartment.
How to maintain cleanliness: 5 rules for the lazy
In order not to resort to general cleaning every month, follow these tips:
Wipe the shelves once a week with a damp cloth with an antibacterial impregnation (Clorox Wipes).
Store opened products in sealed containers (for example, Tupperware or Lock&Lock).
Install carbon filter or ozonizer (for example, Xiaomi Air Purifier Mini) - they absorb odors.
Change once every 3 months water filter (if your model has it).
Do not put hot foods in the refrigerator - steam settles on the walls and promotes the growth of bacteria.
⚠️ Attention: If your refrigerator has one water dispenser, wash it once a month it citric acid solution (1 tsp per 1 liter of water) - this will prevent the formation of mold in the tubes.
