The cleanliness of the refrigerator compartment is not only aesthetics, but also a guarantee of food safety. In a confined space at low temperatures, bacteria and mold actively multiply, which can spoil fresh food and cause food poisoning. Many housewives are wondering how to clean the refrigerator so as not to damage the coating and are guaranteed to destroy germs. The use of aggressive household chemicals is not always justified here, since residues can get into food.
There are many time-tested and science-tested methods that can effectively deal with dirt, grease and unpleasant odors. Baking soda solution or acetic acid are often more effective than expensive sprays. It is important to understand that different surfaces - plastic, glass, metal or rubber - require different cleaning approaches. An incorrectly selected product can lead to clouding of the plastic or drying out of the seals.
In this article we will look in detail at which solutions are safe for the inner chamber, how to wash the outer walls from greasy marks and how to eliminate a persistent odor. We will consider both folk recipes and specialized products, and also give recommendations for caring for complex equipment. Proper care will extend the life of your refrigeration unit and preserve food freshness.
Preparation for general cleaning of the refrigerator
Before you start mixing solutions and rubbing surfaces, you need to properly prepare the equipment. General cleaning requires complete emptying of the chambers from products. This is the only way to get to hard-to-reach places where dirt and bacteria accumulate. If you simply wipe the visible shelves, the effect will be temporary, but the source of the smell may remain.
The most important stage is defrosting. Even if your refrigerator is equipped with a No Frostsystem, it must be disconnected from the network for at least 2-3 hours. In completely frozen systems, during this time the ice in the evaporator will have time to melt, and in models with a drip system (“crying wall”) all the water plugs in the drainage hole will have time to go away. Attempts to break off ice with a knife or heat it with a hairdryer can damage the freon tubes, which will cause expensive repairs.
⚠️ Attention: Never use sharp objects to chip ice! Damage to the internal cooling circuit will result in refrigerant leakage and compressor failure.
While the appliance is defrosting, remove all removable parts: shelves, vegetable drawers, egg trays and door baskets. It is best to wash them separately in the bathtub or sink under running water using a sponge and mild detergent. Glass and plastic do not like sudden temperature changes, so do not place cold shelves directly under hot water - they may crack. Let them warm up to room temperature.
☑️ Preparing for washing
Folk remedies for washing internal chambers
The internal surfaces of the refrigerator come into direct contact with food, so the use of aggressive chemicals such as chlorine or ammonia is undesirable. The best choice would be proven folk remedies that are safe for health and effective against stains. Baking soda is a universal abrasive and adsorbent that is found in every kitchen.
To prepare a cleaning solution, dilute 2 tablespoons of soda in 1 liter of warm water. This solution copes well with greasy deposits and leaves no streaks. Baking soda also has the ability to neutralize acidic odors. After treating with soda solution, the surfaces must be wiped with a clean damp cloth to remove the white coating. For stubborn stains, you can use a paste of baking soda and a small amount of water, applying it with a sponge.
Another powerful remedy is citric acid or fresh lemon juice. The acidic environment perfectly dissolves mineral deposits, traces of berry juices and kills some bacteria. Dissolve 2 tablespoons of citric acid in 0.5 liters of water. Wipe all shelves and walls with this solution. The lemon aroma will give the refrigerator freshness, although it is not a long-term odor absorber, unlike soda.
If the dirt is old and greasy, laundry soap will help. Grate a bar of soap and dissolve the shavings in hot water until you obtain a thick solution. The alkaline environment of soap perfectly breaks down animal fats. However, after such washing you will have to very carefully wipe the surfaces with clean water 2-3 times so that soap stains do not remain on the walls.
Specialized products and household chemicals
When traditional methods do not seem to be effective enough or serious ones are required disinfection (for example, after storing spoiled meat), you can resort to household chemicals. There is a wide range of sprays and gels for cleaning refrigerators on store shelves. They contain surfactants (surfactants) that quickly dissolve dirt, and often have antibacterial additives.
When choosing a product, pay attention to the label “for food surfaces” or “biodegradable”. Such products are easier to wash off and less toxic. Popular sprays are no-rinse sprays (though we still recommend wiping with water) and wet wipes for quick cleaning. Wipes are convenient for removing fresh stains, but for general cleaning they are used up too quickly and are not economically profitable.
There are also special products for cleaning stainless steel if your refrigerator has an external coating made of this material. Conventional products can leave rainbow stains or micro-scratches on stainless steel. Use only polishes with silicone or special antistatic sprays that create a protective film and repel dust and fingerprints.
| Type of product | Effectiveness against grease | Safety for products | Removal odors |
|---|---|---|---|
| Baking soda | Medium | Absolutely safe | High |
| Vinegar 9% | Low | Safe (after airing) | Medium |
| Laundry soap | High | Safe (requires washing) | Low |
| Special. spray | Very high | Requires careful checking | Masks the smell |
Removing difficult stains and grease
Greasey stains are frequent guests on refrigerator doors and shelves. Fat tends to oxidize over time, becoming sticky and difficult to remove. If regular washing does not help, you can use mustard powder. It is a natural fat emulsifier. Dilute the mustard with water until it becomes sour cream, apply to the contaminated area and leave for 10-15 minutes. Then rinse with warm water.
To remove traces of stickers, price tags or tape, use vegetable oil or alcohol. Apply the oil to a cotton pad and rub away the sticky residue. The glue will dissolve and can be easily removed. Alcohol (medicinal or vodka) also works well with the adhesive base, but it must be used carefully on some types of plastic, first checking on an inconspicuous area.
Traces of markers or felt-tip pens left by children can be removed with toothpaste or melamine sponge. The melamine sponge works like an eraser, erasing dirt at the micro level. However, remember that it is an abrasive and can dull glossy plastic with frequent use. Use it precisely, only on problem areas.
⚠️ Attention: Do not use acetone, paint thinners or abrasive powders (such as Pemolux) to clean the plastic inside the refrigerator. They can dissolve the surface or leave deep scratches in which dirt will then accumulate.
Cleaning rubber seals and drainage
The rubber seal on the door is a weak point that is often forgotten. Moisture, crumbs and mold accumulate in the folds of rubber. If you do not clean the seal, it will begin to turn black, crack and lose its seal, causing the refrigerator to keep cold worse and consume more electricity. For cleaning, use a cotton swab dipped in a solution of vinegar or hydrogen peroxide.
After cleaning, it is advisable to lubricate the rubber. glycerin or special silicone grease is perfect for this. Apply the product to a cotton pad and wipe the seal. This will restore elasticity to the rubber, prevent drying out and extend its service life. Glycerin creates a thin protective film that repels water.
Another important element is the drainage hole. It is located on the back wall of the refrigerator compartment (usually in the center or at the bottom side). Condensation escapes through it. If the hole is clogged, water will begin to accumulate at the bottom of the refrigerator or under the drawers. You can clean it using a special brush (often included) or a soft wire wrapped in cotton wool. Carefully insert the tool into the hole and make several rotational movements.
What to do if the drainage is tightly clogged?
If the brush does not help, you can try using a medical bulb (syringe). Fill it with warm water and inject it under pressure into the drainage hole. Water pressure will help break through the blockage of fat and mucus.
Fighting unpleasant odors
Sometimes, even after thorough washing, an unpleasant odor remains in the refrigerator. It could be the smell of fish, meat, or simply “musty.” Before using absorbents, ensure that the source of the odor is physically removed. Check whether liquid has entered the space between the housing and the inner chamber (for example, through drainage).
To eliminate odors, use natural adsorbents. The most affordable option is activated carbon. Grind 10-15 tablets and scatter the powder in small saucers on the shelves of the refrigerator. Leave it for a day. The charcoal will absorb odor molecules. Silica gel (balls from bags with shoes), rice or soda in an open container have a similar effect.
There are also electric odor absorbers powered by batteries that are installed inside the chamber. They ionize the air, destroying bacteria and odors. Also popular are mineral blocks that need to be periodically “recharged” in the sun. However, you should not rely only on them: if the refrigerator smells rotten, no remedy will help until the source is found and removed.
Rules for drying and turning on equipment
After wet cleaning, the refrigerator cannot be immediately filled with food. The interior surfaces must be completely dry, otherwise the remaining moisture will become an ideal breeding ground for bacteria and mold. Wipe all walls and shelves dry with a clean cotton cloth or paper towels. Pay special attention to corners and joints.
Leave the refrigerator doors open for 30-60 minutes for ventilation. This will allow the remaining odors of cleaning products (vinegar, soap) to disappear and the moisture to completely evaporate. If you used strong flavors or chemical sprays, the ventilation time can be increased to 2 hours.
You can turn on the refrigerator only after it has completely dried and warmed up to room temperature. Suddenly turning on the compressor after washing with cold water can be stressful for equipment, although modern models are quite reliable. After turning on, let the refrigerator run idle for 1-2 hours to reach the desired temperature, and only then load food.
Frequently asked questions (FAQ)
Is it possible to wash the inside of the refrigerator with a bleach solution (White)?
You can only use chlorine-containing products in emergency cases for disinfection after storage of heavily contaminated products. Chlorine is toxic and has a persistent odor that takes a long time to soak into plastic. If you used bleach, the refrigerator must be rinsed with water at least 3-4 times and ventilated for a long time. This product is not recommended for regular cleaning.
How often should you wash the refrigerator?
It is recommended to completely defrost and thoroughly clean the refrigerator every 3-4 months. If you have a model with the No Frost system, you don’t need to specifically defrost it, but you should wash the internal surfaces once every 1-2 months. You need to wipe the shelves from fresh stains and check the products weekly.
What should you not wash the refrigerator with?
You should absolutely not use abrasive powders, hard metal brushes, solvents (acetone, gasoline), hot water (above 40-50 degrees) and steam cleaners. These products can damage the coating of the shelves, melt the plastic or deform the seals.
What to do if the smell of detergent remains after washing?
Wipe all surfaces with clean water again. If the smell remains, use a neutralizer - for example, a soda solution, or simply place slices of fresh apple or lemon on the shelves for several hours. Ventilation with open doors is also effective.
