How to wash the walls of the refrigerator from grease: step-by-step instructions and secrets

Greasey deposits on the walls of the refrigerator are a problem that every home cook faces. Over time, even with regular cleaning, a sticky film forms on plastic and metal surfaces, which attracts dust, food residues and unpleasant odors. The back wall (where condensation accumulates) and the shelves above the meat or fish compartment suffer especially badly.

Many people mistakenly believe that it is enough to wipe the refrigerator with a damp cloth - but this only smears the fat, making the surface even more sticky. In this article we will look at fat removal, including specialized chemistry and professional life hacks. You will learn which products are safe for 10 proven methods fat removal, including folk recipes, specialized chemistry and professional life hacks. You will learn which products are safe for No Frost and conventional systems, how to avoid stains, and what to do if fat has become embedded in the plastic.

Important: methods differ for refrigerators with antibacterial coating (for example, y LG BioShield or Samsung Twin Cooling Plus) - aggressive compounds can damage the protective layer. All recommendations take into account the features of modern models with ion purification and carbon filters.

Why fat accumulates in the refrigerator and why it is dangerous

Greasy deposits are formed due to fumes from foods: meat, fish, sauces, butter and even dairy products. When the door is opened, warm air condenses on the cold walls, and fat particles “stick” to the moisture. Over time, this leads to:

• 🦠 Reproduction of bacteria (especially Salmonella and E. coli), which can cause food poisoning;
• 🤢 The appearance of a persistent “rotten” odor that is absorbed into food;
• 🔥 Deterioration of the system No Frost - fat clogs the drainage holes, causing ice;
• 💡 Yellowing of plastic and loss of shine of metal parts (in models with stylish design type Bosch VitaFresh).

The most fat accumulates in areas with high humidity: on the back wall (where the evaporators are located), under the egg trays and on the sealing rubber band. In refrigerators with freshness zones (for example Liebherr BioFresh) plaque may appear within 2-3 months due to intense circulation. air.

⚠️ Attention: If your refrigerator is equipped with carbon filter (for example, in Sharp Plasmacluster), greasy deposits reduce its service life by 2 times. The filter begins to absorb odors worse, and it has to be changed more often.

Preparing the refrigerator for cleaning: 5 mandatory steps

Before you begin removing grease, the refrigerator must be properly prepared. This will speed up the process and protect the equipment from damage.

1. Turn off the power. In models with electronic control (for example, Samsung Family Hub) after turning off, wait 5-10 minutes - this will prevent voltage surges when you turn it back on.
2. Take out all the products. Place them in a cooler bag or a bowl with ice. If there is ice on the walls (in systems without No Frost), wait for it to melt - it is useless to clean icy surfaces.
3. Remove all removable elements: shelves, drawers, grates. It is better to wash them separately in warm water with soda.
4. Check the drainage hole (usually located on the back wall). If it is clogged with grease, clean it with a cotton swab or a special brush.
5. Prepare the tools: soft sponges (for example, Scotch-Brite), microfiber cloths, a toothbrush for hard-to-reach places, rubber gloves.

For refrigerators with display or touch panel (as u LG InstaView) use alcohol wipes - they will remove greasy prints without damaging the coating. Do not use abrasives or hard brushes!

Top 5 folk remedies for removing grease without chemicals

If you prefer environmentally friendly methods or are afraid of damaging the coating of the refrigerator, start with folk recipes. They are safe for all types of surfaces, including antibacterial And ionic.

For heavily. contaminated refrigerators (for example, after a long period of inactivity), combine the products. First, apply soda slurry for 15 minutes, then treat with a vinegar solution - this will enhance the effect. After cleaning, wipe the surfaces with a solution of water and ammonia (1 tsp per 1 liter of water) to remove stains.

⚠️ Attention: Do not use hot water (above 40°C) to wash refrigerators with plastic panels - this may deform them In models with glass shelves (For example, Beko EverFresh+) temperatures up to 60°C are allowed.

Professional chemistry: what to choose for complex stains

If traditional methods do not help, it’s the turn of specialized ones. funds. They cope with old fat, rust and mold, but require caution in use.

• 🧴 Sprays for refrigerators: Topperr 3104, Sano Refrigerator Cleaner. Contains antibacterial components and does not require rinsing.
• 🧽 Dishwashing gels: Fairy Platinum, AOS. Apply for 5-7 minutes, then wash off with a damp sponge.
• 🧪 Alkaline cleaners: Scholl Cif, Mr. Proper. Effective for stubborn grease, but can damage aluminum parts.
• 🧼 Tablets for dishwashers: Finish, Somat. Dissolve 1 tablet in 1 liter of warm water - you will get a powerful anti-grease solution.

For refrigerators with stainless steel (for example, Smeg FAB28) use products marked "for metal", for example, Dr. Beckmann. They do not leave streaks and protect against corrosion. But chlorine-containing compositions (such as Domestos) are strictly prohibited - they destroy the antibacterial coating and cause rust.

When working with chemicals, be sure to:

• 😷 Use rubber gloves a mask (especially when cleaning with vinegar or ammonia);
• 🕒 Observe the exposure time - exceeding it can lead to damage to the plastic (for example, in refrigerators Indesit older than 2018, the plastic becomes brittle after contact with alkalis for longer than 10 minutes);
• 💧 Carefully rinse off any remaining product - their particles can get into the products.

What to do if the chemistry did not help?

If there is fat left after cleaning, try the mechanical method: apply it to a sponge fine salt (Extra type) and gently rub the contaminated areas. Salt acts as a mild abrasive without scratching the surface. After treatment, wash off the residue with a damp cloth.

How to wash off grease in refrigerators with a No Frost system

Refrigerators with No Frost (for example, Atlant XM 6025-031 or Haier C2F636CWG) require a special approach. Their main feature is that they are blown with air. Fat getting on these parts can: hidden evaporatorswhich are blown with air. Fat getting on these parts can:

• 🔥 Cause overheating of the compressor (due to deterioration of heat transfer);
• ❄️ Lead to formation of ice in unexpected places;
• 🦠 Provoke the appearance mold in the air ducts.

For cleaning No Frost:

1. Turn off the refrigerator and wait until it thaws completely (if there is ice).
2. Remove protective cover on the back wall (in most models it is attached to latches).
3. Use a vacuum cleaner with narrow nozzle remove dust and greasy deposits from the evaporator.
4. Wipe everything surfaces a solution of vinegar and water (1:3) - it dissolves fat and disinfects.
5. Turn on the refrigerator for 1 hour to dry the system. mode super freezing for 1 hour to dry the system.

⚠️ Attention: Never use steam generators or hot air (for example, a hair dryer) for cleaning No Frost! This can melt the plastic parts of the air ducts (in models Electrolux they are made of polystyrenewhich deforms at 70°C).

If your refrigerator has ionizer (for example, Panasonic NR-BN30A1), after cleaning, turn it on for 2-3 hours - this will speed up the neutralization of odors.

Cleaning the drainage hole and hidden areas

The drainage hole (usually located at the bottom of the back wall) often becomes clogged with grease, which leads to water accumulation under the vegetable drawers. To clean it:

1. Take a cotton swab or pipe cleaner.
2. Dip into a solution of soda and vinegar (1:1).
3. Gently scroll in the hole, then rinse warm water from the syringe.

For hard-to-reach places (for example, under a rubber seal or behind shelf fastenings):

• 🪥 Use toothbrushmoistened with ammonia solution (1 tsp per glass of water);
• 🧲 Suitable for metal parts WD-40 (spray, then wipe dry rag);
• 🧴 For plastic grooves - silicone grease (after cleaning) to prevent grease from sticking.

In refrigerators with automatic defrosting (for example, Whirlpool ART 9810) the drainage system can be self-rinsing. In this case, it is enough to pour 50 ml citric acid solution mode (1 tsp per 100 ml of water) into the hole and turn on the "Super cooling".

How to prevent the formation of grease: 7 simple rules

To make grease deposits appear less often, follow these recommendations:

• 📦 Store foods in containers. Especially meat, fish and sauces - they are the main sources of fat;
• 🧊 Use odor absorbers. Gel (Air Wick) or coal (Filtero) neutralize grease fumes;
• 🕒 Ventilate the refrigerator once a week: leave the door open for 10-15 minutes (in models with No Frost 5 minutes is enough);
• 🧴 Apply a protective coating. After cleaning, wipe the walls glycerin (sold at the pharmacy) - this will create a thin film that repels fat;
• 🌡️ Control the temperature. At +5°C fat solidifies and evaporates less (optimal for the freshness zone);
• 🧼 Wash the refrigerator once a month. It is enough to wipe the walls soda solution (1 tbsp per 1 liter of water);
• 🔄 Change the rubber seal every 3-5 years. Over time, it loses its elasticity and lets warm air through, accelerating the formation of plaque.

In refrigerators with self-cleaning function (for example, Hisense RS694N4BC1) it is enough to start it once every 2-3 months. However, even in such models it is recommended manual cleaning drainage and seal.

FAQ: Frequently asked questions about cleaning the refrigerator from grease

You can Is it possible to use a melamine sponge to clean the refrigerator?

You can use a melamine sponge only for smooth surfaces (glass, stainless steel). It is too abrasive for plastic and can leave microcracks into which fat will then clog. In refrigerators with antibacterial coating (for example, Toshiba GR-RF410WE) melamine destroys the protective layer.

How to get rid of yellowness on plastic after cleaning?

Yellowness appears due to fat oxidation or the use of aggressive agents (for example, bleach). To whiten plastic:

1. Wipe the surface hydrogen peroxide (3%);
2. Apply paste of soda and toothpaste powder (1:1), leave for 20 minutes;
3. For stubborn stains, use plastic bleach (for example, Retrobright).

In refrigerators with with silver coating (for example, Samsung RB37J5240SS) yellowness can be removed only special polishes for metal.

How to clean a refrigerator with an ozonizer function?

In models with ozonator (for example, Midea MRF523SFN) you cannot use products with ammonia (ammonium) or chlorine —they neutralize the effect of ozone. Optimal options:

• Solution vinegar with water (1:5);
• Special sprays for refrigerators with ionization (for example, Topperr Ozone Safe);
• Lemon acid (1 tsp per 1 liter of water).

After cleaning, turn on the ozonizer for 1-2 hours to restore the antibacterial effect.

How often should you wash the refrigerator so that grease does not accumulate?

The frequency of cleaning depends on the intensity of use:

• 1 time per month — if the refrigerator is full 70% or more; Once a month data-i="359">once every 3 months
• 1 time every 2 months — at average load (30–50%);
• 1 time every 3 months - if the refrigerator is almost empty or is used as a backup.

In models with Air Flow system (for example, BEKO GNE114620X), fat is distributed more evenly, so cleaning once every 2 months is sufficient.

Is it possible to clean a refrigerator with a steam generator?

A steam generator can be used only for external surfaces and removable shelvesIt is dangerous for internal cleaning:

• In refrigerators with plastic walls steam can cause deformation;
• In models with No Frost hot steam will damage air ducts;
• In refrigerators with display (for example, LG Instaview) steam can penetrate into the electronic unit.

An alternative is warm moist air (for example, from a hair dryer in the "cold blow" mode). It is safe and helps soften grease before cleaning.
