Refrigerator hygiene is not just a matter of aesthetics or smelling good, but is a critical aspect of food safety. Inside the device, despite low temperatures, bacteria such as listeria and salmonella, which are able to survive in the cold, actively multiply. Regular wet cleaning helps prevent cross-contamination and extend the life of the unit, maintaining its energy efficiency.
Many owners mistakenly believe that the cold kills all germs, so they limit themselves to only periodically throwing away spoiled food. However old stains spilled sauces or juices become an ideal habitat for pathogenic microflora. In addition, a layer of grease and dirt on the inner walls impairs heat transfer, forcing the compressor to work with increased load. The right approach to cleaning begins with understanding which products are safe for plastic and which can cause irreparable damage.
In this article we will analyze a detailed algorithm of actions that will help you bring your equipment into perfect condition without the risk of damaging surfaces. You will learn why you should not use aggressive chemicals, how to effectively deal with unpleasant odors, and what tools are really necessary for high-quality cleaning.
Preparation for wet cleaning and defrosting
Before starting any manipulations, you must completely empty the internal space of food. This is an obvious, but often overlooked step that allows for high-quality disinfection of all shelves and drawers. If your refrigerator does not have a No Frostsystem, a complete defrost will be required. To do this, unplug the appliance from the power supply, open the doors and leave it for several hours until all the ice has melted.
To speed up the process, you can use special defrosting sprays or place a container with warm water inside, but under no circumstances try to chip the ice with a knife or sharp objects. Damage to the evaporator is one of the most common and costly breakdowns that occurs due to the carelessness of owners during a rush.
While the camera is freeing itself from ice, take care of the removable elements. Tempered glass shelves and plastic containers are best removed and washed separately in the bathtub or sink. Sudden changes in temperature can cause cracks, so do not wash cold glass with hot water. Allow parts to warm to room temperature before contact with warm water.
⚠️ Warning: Never use a hair dryer or other heating device to speed up the melting of ice. Hot air can damage the plastic inner casing and deform the seals.
Choosing safe detergents
The household chemicals market offers many specialized sprays, but simple and affordable substances are often sufficient for regular cleaning. The main rule is that the product should not contain abrasive particles and aggressive solvents that can make the plastic cloudy or cause microcracks. Baking soda table vinegar remains the leader in the category of safe cleaners.
A solution of laundry soap or detergent is excellent for removing grease stains dishes. It is important to rinse off the foam thoroughly, as surfactant residues can be absorbed into the plastic and subsequently end up on food. If you prefer ready-made sprays, choose those that are labeled “safe for food surfaces” or “antibacterial.”
Can you use bleach?
You can use chlorine-containing products (for example, Domestos or Belizna) only to disinfect heavily contaminated areas or fight mold, but after this, repeated rinsing with water is required. Chlorine has a strong odor that takes a long time to dissipate, and can oxidize some types of plastic, making them yellow and brittle.
Always wear rubber gloves when working with chemicals. Even mild products can dry out the skin of your hands with prolonged contact. To polish the external surfaces of stainless steel, there are special spray polishes that prevent the appearance of fingerprints, but for internal chambers they are not required and are even harmful.
Step-by-step instructions: how to wash the inside of the refrigerator
The cleaning process should start from the top shelves, gradually going down. This will avoid re-contamination of already clean surfaces with dirty water flowing down. Use a soft sponge or microfiber. The hard side of the sponge is only permissible for glass shelves, but it is strictly forbidden to rub plastic and rubber seals with it.
☑️ Algorithm for washing the camera
Pay special attention to the door pockets and sealing rubber bands. It is in the folds of rubber that mold and black slime most often accumulate. Wipe the seal away from you, carefully cleaning every millimeter of the fold. If you find blackening that does not come off, try using a cotton swab dipped in hydrogen peroxide or an alcohol solution.
| Cleaning area | Recommended product | Tool | Frequency |
|---|---|---|---|
| Glass shelves | Glass cleaner or soap solution | Soft sponge, dry cloth | Once every 1-2 months |
| Plastic boxes | Warm water with soda | Sponge, soft bristle brush | Once a month |
| Rubber seal | Vinegar solution or peroxide | Cotton pad, swab | Once every 2 weeks |
| Internal walls | Specialized spray or soda | Microfiber | Once every 3 month |
After treating all surfaces with a damp cloth, be sure to wipe them dry. Residual moisture can quickly turn into an icy crust or cause a musty smell. Before turning on the device, make sure that all parts are completely dry.
Elimination of unpleasant odors and mold
The appearance of a foreign aroma is a signal that bacteria have settled in the refrigerator or a forgotten product remains. Before using fragrances, the source of the odor must be found and eliminated. If simple washing is not enough, you will need absorbents substances that absorb odors.
An effective and cheap way is to use activated carbon. It is enough to crumble 10-15 tablets and place them in an open container on a shelf for a day. Ground coffee, soda in an open jar, or silica gel also do an excellent job. These products are safe for products and do not create artificial “chemical” fragrances.
If you find mold on food or walls, you need to act immediately. Mold spores are toxic and spread quickly. Affected products should be thrown away and the chamber should be treated with a vinegar solution or special antibacterial agents. After disinfection, it is better to leave the refrigerator open for several hours for ventilation.
⚠️ Attention: If mold has penetrated deep into the pores of a plastic box or seal and is not removed mechanically, it is better to replace the part. Fungal spores can continue to multiply inside the plastic, constantly contaminating the air in the chamber.
Care for the external surface and back wall
The appearance of the refrigerator often suffers from greasy stains, especially if the kitchen is small or there are small children. For stainless steel cases, use only special products or a diluted alcohol solution, wiping the surface strictly along the metal fibers. This will prevent rainbow marks and scratches from appearing.
Do not forget about maintenance of the external part. Once every six months, it is recommended to move the refrigerator aside and vacuum the condenser grille on the back wall (if it is open) or wipe the bottom of the case. Dust on the radiator impairs heat transfer, which leads to overheating of the compressor and increased energy consumption.
Check the tilt level of the refrigerator. It should be level or slightly sloping back so that the doors close on their own. Adjustment is carried out using the front support legs. If the refrigerator is crooked, the seal may not fit tightly, which will lead to the formation of ice and loss of cold.
Typical mistakes when cleaning a refrigerator
Even experienced housewives sometimes make mistakes that can shorten the life of the equipment. One of the most common is to use hot water to wash the interior plastic parts. The plastic in refrigerators is often thin and sensitive; from boiling water it can become deformed or become covered with a network of small cracks, in which dirt will then accumulate.
Another mistake is using scrapers, knives or blades to remove frozen ice. As mentioned earlier, this is a direct path to breakdown of the cooling system. You should also not wash the refrigerator while it is plugged in, unless it is a quick surface wipe. A full wash requires disconnecting from electricity.
Do not use aromatic oils directly on the shelves. Oils can react with plastic, corroding it, or transfer to food, changing its taste. For aromatization, use only dry substances in open containers.
What to do with the drainage hole?
To clean the drainage, use a soft brush (for example, for cleaning bottles) or a medical bulb. Carefully insert the brush into the hole and make several rotational movements, then rinse the canal with warm water from a syringe without a needle.
Frequently asked questions (FAQ)
How often should you wash the refrigerator?
General cleaning with defrosting (if there is no No Frost) is recommended once at 3-4 months. However, you should wipe down shelves and check food for freshness weekly. It is advisable to wipe rubber seals with a damp cloth once every two weeks to prevent drying and cracking.
How to wash yellow deposits on plastic?
Yellowishness often appears from the age of the plastic or contact with fat. Try making a paste of baking soda and water, apply for 15-20 minutes, then rinse. A solution of hydrogen peroxide is also effective. If the yellowing is caused by the age of the material, it may not be possible to completely return the white color, but lightening is possible.
Is it safe to use a steam cleaner?
Use a steam cleaner inside the refrigerator not recommended. The high temperature of the steam can deform the thin plastic of the shelves and damage the thermal insulation layer. Steam cleaning is only permissible for external metal surfaces, provided that the moisture is quickly wiped off.
How to remove the smell after defrosting?
After defrosting, the smell of dampness is normal. Wipe all surfaces with a solution of vinegar (1:3 with water), then with clean water. Leave the doors open for 5-6 hours (preferably overnight) for complete ventilation. Placing activated carbon inside the chamber will also help.
Is it possible to wash a refrigerator with the compressor on?
It is strictly not recommended. Water and electricity are a dangerous combination. In addition, when the compressor is running, the inner walls are very cold and the detergent may freeze, and sudden contact with warm water will stress the materials. Always unplug the appliance from the outlet before washing.
