How to clean the refrigerator: proven products and step-by-step instructions

Refrigerator - the only household appliance that works without interruption 24/7, accumulating inside not only food, but also persistent dirt. Grease stains from sausage, stains from spilled juice, mold in the corners and an unpleasant odor - every home cook faces these problems. However, cleaning the refrigerator requires not only patience, but also knowledge of the right means: aggressive chemicals can ruin rubber seals, and traditional methods sometimes leave stains or do not cope with bacteria.

In this article we will look into safe and effective methods clean the refrigerator inside and out - from improvised means (soda, vinegar, lemon) to professional chemicals (Bagi "Shumanit", Cillit Bang). You will learn how to remove old grease from plastic shelves without scratches, eliminate the smell of fish or onions, and why you should not use hot water to wash the freezer. We will also provide a checklist for preparing for cleaning and a table of compatibility of products with different types of refrigerator coatings (No Frost, drip system, inox).

Preparing the refrigerator for cleaning: 5 mandatory steps

Before grabbing a sponge, the refrigerator needs to be properly prepared. Neglecting this step leads to two common problems: damage to equipment (for example, a short circuit due to water getting into the vents) or ineffective cleaning (when dirt is simply spread over the surface).

Here's what needs to be done before washing:

Unplug the refrigerator (unplug from the socket!)

Take out all the products and put them in a cooler bag or a bowl of ice

Remove all removable elements (shelves, drawers, racks)

Check the water temperature - it should be room temperature (not higher than 30°C)

Prepare an absorbent rag to collect condensation-->

Pay special attention freezer compartment: if it is covered with ice, first wipe defrosting. In models with the system No Frost ice usually does not form, but the condensation on the back wall still needs to be wiped off. Do not use a knife or other sharp objects to remove ice - this way you risk damaging the evaporator.

⚠️ Attention: If your refrigerator is equipped with electronic display. data-i="81">dry microfiber or touch buttons, avoid getting water on the control panel. To clean, use dry microfibermoistened in a weak alcohol solution (1:1 with water).

Folk remedies for cleaning the refrigerator: pros and cons

Many housewives prefer to do without aggressive chemicals, using what they have at hand. Folk remedies really cope with light stains and disinfection, but it is important to understand their limitations. For example, vinegar kills bacteria perfectly, but can leave a persistent odor, and soda is powerless against old fat.

Consider the most popular options:

• 🍋 Lemon juice or acid: removes odors and brightens yellowed plastic parts. Dissolve 2 tbsp. juice in 1 liter of water. Minus: not suitable for marble or stone surfaces (may cause corrosion).
• 🧂 Baking soda: safe for all surfaces, neutralizes odors. Dilute 3 tbsp of soda in 1 liter of warm water. Minus: has a weak effect on greasy stains.
• 🥛 Milk or whey: unexpected solution to eliminate odors. Wipe the inner walls with a cloth soaked in milk, then rinse with water. Minus: may leave a film that will then have to be washed off.
• 🧽 Laundry soap (72%): disinfects and removes grease. Grate the bar, dissolve in hot water (but cool before use!). Minus: requires careful rinsing, otherwise soap residue remains.

Folk (soda, vinegar, lemon)

Special chemicals for refrigerators

Universal detergents (for example, Fairy)

Do not wash at all/very rarely-->

For disinfection after washing you can use hydrogen peroxide (3%): spray it on the surface, leave for 5-10 minutes, then rinse off. This product kills up to 99% of bacteria, including salmonella and E. coli, but leaves no odor.

⚠️ Attention: Never mix vinegar and bleach (or other chlorine-containing products) - this releases toxic gas chlormine, hazardous to respiratory tract ways.

Professional chemistry: what to choose for different types of pollution

If folk remedies don’t work - for example, the refrigerator has not been washed for years, or black deposits have accumulated at the bottom of the freezer - it’s time to turn to specialized chemistry. The main rule: choose products with. marked "for refrigerators" or "food-safe" (safe for contact with food).

The table below compares popular products in terms of effectiveness and safety:

For freezer It is better to choose products in the form spray —they are more convenient to apply on vertical surfaces. And for sealing gum (which is often covered with black mold) gel with whitening effect, for example, Domestos “Whiteness”is suitable, but it must be diluted with water. (1:3) and rinse thoroughly.

How to clean a refrigerator with a No Frost system: care features.

Refrigerators with technology No Frost (for example, models Samsung RB30J3000WW or LG GA-B409SQDL) do not require defrosting, but this does not mean that they can be washed less often. The ventilation holes in such devices are often clogged with dust and grease, which leads to compressor overheating and increased energy consumption.

Cleaning algorithm for No Frost:

1. Turn off the refrigerator and remove all products.
2. Remove protective cover from the ventilation hole (usually it is secured with latches).
3. Vacuum the holes with a soft brush (you can use the attachment from a furniture vacuum cleaner).
4. Wipe the inner walls with a soft sponge with detergent, avoiding water getting on the fan.
5. Pay attention drainage hole (located at the back, at the bottom of the chamber) - clean it with a cotton swab.

For No Frost you should absolutely not use steam generators or hot water - this may damage the automatic defrosting system. Also avoid abrasive products (for example, powders with particles), which scratch the plastic and interfere with air circulation.

What will happen if you do not clean the ventilation in No Frost?

Clogged ventilation ducts lead to uneven cooling (in some zones, the temperature rises to +8...+10°C, which is dangerous for food). This also increases the load on the compressor, reducing the life of the refrigerator by 20–30%.

Elimination of persistent odors: from fish to mold

Even after thorough washing, the refrigerator can retain unpleasant odors. The culprits are plastic pores, into which aroma molecules penetrate, and bacteria, remaining in secluded places (for example, under a rubber seal). Here's how to deal with them:

• ☕ Activated carbon: place 5-10 tablets in a small container and leave in the refrigerator for 24 hours. Charcoal will absorb odors and moisture.
• 🍎 Apple peelings or lemon slices: put them on a shelf for 1-2 days. Fruit acids neutralize ammonia odors (for example, from fish).
• 🧂 Salt + rice: mix in equal proportions, pour into a fabric bag and place in a chamber for a day. Rice absorbs moisture, salt absorbs odors.
• 🌿 Essential oils: 2-3 drops of eucalyptus or clove oil on cotton wool, place on the top shelf. Important: do not drop oil on plastic - it can corrode it!

If there is a smell mold, it means that a colony of fungus has accumulated somewhere. Usually it is hidden:

• Under the sealing rubber;
• In the drainage hole;
• Behind the back wall (in models with a drip system).

For For disinfection, use copper sulfate solution (1 tsp per 1 liter of water) or chlorhexidine (0.05%). Apply the product to problem areas, leave for 15 minutes, then rinse. After treatment, wipe the surfaces with a dry cloth and ventilate the refrigerator for 3-4 hours.

Cleaning external surfaces: stainless steel, plastic, glass

Exterior of the refrigerator also requires care. Dust on the back wall impairs heat transfer, and stains on the facade spoil the aesthetics. The coating material dictates the choice of product:

• 🔄 Stainless steel (inox): use special polishes (Electrolux Stainless Steel Cleaner) or a vinegar solution (1:1 with water). Wipe along metal structureto avoid streaks.
• 🧴 Plastic: regular dishwashing detergent will do (Frosch, AOS). For glossy surfaces, add 1 tbsp to the water. l. ammonia - this will add shine.
• 🥛 Glass: use glass spray (Mr. Proper) or starch solution (1 tbsp per 1 liter of water). Do not use acetone or solvents - they cloud the glass.
• 🖼️ Wood or stone decor: clean only with a soft cloth with a soap solution. Abrasives or brushes will damage the texture.

Don't forget about rear wall the refrigerator: dust on the radiator increases energy consumption by 15-20%. To clean, use vacuum cleaner with a narrow nozzle or paint brush (soft bristles will not damage the tubes). Before cleaning, be sure to unplug the refrigerator!

⚠️ Attention: If your refrigerator equipped water dispenser (for example, Samsung RF23HCEDBSR), clean it separately: pump 1-2 liters of water through the system with the addition of vinegar (1 tablespoon per 1 liter), then rinse with clean water. This will remove limescale and bacteria.

What not to do when washing a refrigerator

Some actions seem to speed up the cleaning process, but in fact lead to breakage or damage to surfaces. Here top 5 prohibited practices:

• 🔥 Hot water: the plastic may become deformed, and the sealing rubber may lose its elasticity. The optimal temperature is 25–30°C.
• 🧼 Concentrated acids/alkalis: toilet or sewer cleaners (Mole) corrode plastic and metal.
• 🧽 Metal sponges or scrapers: they scratch the coating, dirt then accumulates in microcracks.
• 💦 Abundant pouring of water: moisture can get into electrical components (for example, in thermostat or fan).
• ❄️ Blow drying: a sharp temperature change is harmful to the seal and can cause cracks in the plastic.

You should also not:

• Use scented candles or air fresheners inside the refrigerator - they can give the products a chemical taste.
• Wash the refrigerator turned on - even if it is operating in vacation (for example, Liehberr CNes 4355).
• Leave wet shelves after washing - this provokes rust on the metal parts.
