The hygienic condition of the refrigeration chamber directly affects the safety of food and your health. Accumulation of bacteria on shelves and walls can lead to rapid spoilage of food and the appearance of a persistent unpleasant aroma that permeates even hermetically sealed goods. Regular wet cleaning is not just an aesthetic procedure, but a necessity to maintain the proper operation of the unit.
Many housewives are wondering how to clean the inside of the refrigerator from dirt, so as not to damage the plastic surfaces and rubber seals. Aggressive chemicals can cause microcracks in the plastic or deform the sealing rubber, which will lead to depressurization of the chamber. Therefore, the choice of cleaning agent must be reasonable and safe for food areas.
In this article we will look at proven methods for removing complex contaminants, including old grease and traces of mold. You will learn how to properly prepare equipment for washing and what tools are best suited for delicate cleaning of internal elements.
Preparing the refrigerator for general cleaning
Before you begin actual washing, you need to properly prepare the unit. Disconnection from the network is the first and mandatory step that ensures the safety of work and prevents compressor breakdown. You should not ignore this stage, even if you plan to just quickly wipe the shelves.
After disconnecting, you should completely empty the chambers of food. If it's winter outside, you can take the food out onto the balcony, otherwise use thermal bags or cooler bags. Defrosting This is a critical step for older models with a drip system, although modern units with No Frost also require periodic complete thawing.
⚠️ Attention: Do not use a knife or other sharp objects to chip ice. Damage to the evaporator will lead to a freon leak and costly repairs.
Remove all removable elements: shelves, drawers, egg trays and bottle containers. It is more convenient to wash them separately in a bathtub or large basin using warm water. Plastic parts may be fragile once cooled, so let them sit at room temperature for a while before washing with hot water.
☑️ Preparing for washing
Folk remedies for safe cleaning
Home recipes are often more effective than store-bought chemicals, especially when it comes to food areas. Baking soda is one of the most popular soft abrasives. It perfectly removes dirt and neutralizes unpleasant odors without leaving toxic traces.
To prepare the solution, mix two tablespoons of soda with a liter of warm water. This composition is ideal for washing interior walls and plastic boxes. Acetic acid has also proven itself as a powerful disinfectant that kills up to 99% of bacteria and removes limescale.
Another effective remedy is ammonia. It is especially good for removing grease stains and restoring plastic to its original shine. However, you need to work with it carefully, ensuring that the room is well ventilated, since ammonia vapors can be dangerous if inhaled in high concentrations.
Household chemicals: what is possible and what is not
When choosing industrial products, it is important to pay attention to their composition and purpose. Dishwashing detergents suitable for removing fresh contaminants, but can leave a film that is difficult to wash off. Gels for cleaning bathtubs and plumbing fixtures are strictly prohibited due to their high aggressiveness.
There are specialized sprays for cleaning refrigerators, which often have an antibacterial effect. They are easy to use because they do not require rinsing (if indicated on the package) and quickly eliminate odors. When purchasing, be sure to check the food contact safety label.
The table below compares popular types of cleaners:
| Type of product | Efficacy against grease | Safety for plastic | Odor removal |
|---|---|---|---|
| Soda solution | Medium | High | High |
| Vinegar solution | Low | High | Medium |
| Dishing detergent | High | Medium | Low |
| Special product for refrigerators | High | High | High |
Removal of complex contaminants and yellowness
Over time, white plastic may turn yellow, and a persistent coating may form in hard-to-reach places. Toothpaste or powder has a slight whitening effect and can help restore surfaces to a neat appearance. Apply a small amount of paste to a soft sponge and gently rub the problem area.
To remove traces of tape or stickers, use vegetable oil or a special solvent for glue that does not leave marks (for example, Citrus Cleaner). The oil is applied to a cotton pad and left for a few minutes, after which the glue is easily removed.
If mold appears on the walls that cannot be removed with soda, you can use hydrogen peroxide. It is safer than chlorine-containing products and effectively fights fungal spores. Treat the affected areas and leave for 10-15 minutes, then wipe thoroughly with a damp cloth.
⚠️ Attention: Never mix cleaning products containing chlorine with acids or ammonia. This can lead to the release of a toxic gas that is hazardous to breathing.
How to remove the smell of fish or meat?
If foods with a strong odor have been in the refrigerator for a long time, wipe all surfaces with a solution of citric acid (1 sachet per liter of water) or use activated carbon, spreading it out in containers on the shelves for a day.
Cleaning rubber seals and vents
Sealing rubber is an element that is most often overlooked, although it is where most dirt and mold accumulate. Flexible cuffs should be wiped with a cotton swab dipped in a vinegar solution or a special cleaner rubber to maintain their elasticity.
Ventilation holes in the back of the camera also require attention. Dust-clogged channels interfere with air circulation, forcing the compressor to work harder. To clean them, use a soft brush or a vacuum cleaner with a narrow nozzle at minimum power.
After cleaning the rubber bands, it is recommended to lubricate them with a thin layer of glycerin or silicone oil. This will prevent drying and cracking of the material, extending the service life of the seal and ensuring a tight fit of the door.
Final drying and turning on the equipment
After completing wet cleaning, all surfaces must be completely dry. Residual moisture may cause the formation of new mold or ice crust immediately after switching on. Wipe all shelves and walls with dry microfiber or paper towels.
Assemble the refrigerator in reverse order, installing clean and dry drawers and shelves. Don't rush to load products right away. Let the unit run idle for 1-2 hours until it reaches the required temperature.
Check the operation of the door and the tightness of the seal. If everything is in order, you can carefully place the products, observing the rules of product proximity. Regular cleaning, carried out every 3-4 months, will keep the equipment in perfect condition for years.
⚠️ Attention: Models with the No Frost system may require less defrosting, but manufacturers still recommend complete cleaning and defrosting at least 1-2 times a year for prevention.
Is it possible to wash the refrigerator without turning it off? it from the socket?
Technically, you can quickly wipe the shelves while the unit is running, but full-fledged general cleaning with defrosting and washing removable parts cannot be carried out. A running compressor may overheat if the door is open for too long, and water may get on the electrical contacts.
How often should you wash the inside of the refrigerator?
The recommended frequency of general cleaning is once every 3-4 months. However, you should wipe down shelves and check food for freshness weekly. If there is a spill of liquid or damage to the product, cleaning must be carried out immediately.
What absolutely cannot be used to clean the refrigerator?
It is prohibited to use abrasive powders (such as Pemolux for baths), hard metal brushes, pure chlorine-containing bleaches and solvents (acetone, gasoline). These substances destroy plastic, leave scratches and can be toxic to food.
What to do if there is a chemical smell left after washing?
It is necessary to re-wipe all surfaces with clean water. To neutralize the odor, you can use a solution of water with a few drops of essential oil or place it inside a container with ground coffee or activated carbon for a day.
