Sooner or later, every owner of refrigeration equipment faces an unpleasant situation: a persistent foreign odor, a sticky coating, or, even worse, traces of mold on the shelves appear inside the chamber. Plastic surfaces, from which the internal containers and shelves are made, tend to absorb food odors, and the micropores of the material become an ideal environment for bacterial proliferation. Ignoring this problem not only creates discomfort when opening the door, but also directly affects the safety of stored products.
Many housewives make the mistake of starting to rub dirt with aggressive household chemicals or abrasive sponges, without thinking about the consequences. Polypropylene and ABS plasticused in modern models Bosch or LGmay become cloudy, become covered with microcracks or change color when exposed to caustic substances. That is why it is important to know which products are truly effective, and which ones it is better to refrain from in order to preserve the original appearance of the equipment.
In this article we will analyze in detail the algorithm of actions for deep cleaning of internal chambers, consider folk and professional methods for removing complex contaminants. You will learn how to get rid of yellowness, neutralize the smell of spilled milk or meat, and what preventive measures will help maintain perfect cleanliness for years without unnecessary effort and expense.
Preparation for cleaning and safety precautions
Before taking active steps, you need to properly prepare the workspace and the equipment itself. First rule reads: No manipulations with the internal surfaces can be carried out while the refrigerator is connected to the mains. This safety requirement is dictated by the risk of moisture getting on electrical contacts, especially in the area of the backlight or thermostat.
Free all shelves from products. If you can keep some of them, put them in ice packs or a thermal bag to prevent them from spoiling during the procedure. Remove all removable items: glass shelves, plastic vegetable containers, egg trays and bottle holders. It is more convenient to wash them separately in a bathroom or large basin where there is access to running water.
⚠️ Attention: Never use hot water at a temperature above 40-45 degrees to wash the internal chambers of the refrigerator. A sudden change in temperature can lead to deformation of thin plastic or cracks on glass shelves.
Prepare the necessary tools in advance. You will need soft sponges, microfiber, a spray bottle and perhaps a soft brush for hard-to-reach areas. Do not use hard metal scrapers or abrasive powders, as they will leave scratches on the plastic, into which dirt will subsequently become clogged.
☑️ Preparation checklist
Effective folk remedies for washing plastic
Home recipes often turn out to be more effective than expensive chemicals, especially when it comes to food contamination. They are safe, environmentally friendly and, as a rule, every home cook already has them in her kitchen. The main advantage of such methods is the absence of the risk of poisoning by chemical vapors during subsequent storage of products.
One of the most popular means is baking soda. It works great as a soft abrasive and adsorbent that absorbs unpleasant odors. To prepare the solution, dilute 2 tablespoons of baking soda in a liter of warm water. This solution can be used to wipe both the body itself and removable parts. After treatment, the surfaces do not require thorough rinsing with a large amount of water, just wipe them with a damp cloth.
The secret to removing old stains
If the soda solution cannot cope with stubborn stains from berries or sauces, apply a slurry of soda and a small amount of water to the stain. Leave for 15-20 minutes, then rub gently with the soft side of the sponge. Abrasive particles of soda will lift dirt from the pores of the plastic without damaging its structure.
Another powerful ally in the fight for cleanliness is acetic acid. It has disinfecting properties and effectively breaks down fatty stains. Mix table vinegar (9%) with water in a ratio of 1:2. If the smell of vinegar seems too strong to you, add a few drops of lemon or mint essential oil to the solution. However, you should be careful with rubber seals: frequent use of acid can dry out the rubber.
- 🍋 Citric acid: perfectly removes scale and refreshes plastic, leaving a pleasant citrus aroma.
- 🧼 Household soap: a natural antiseptic that removes grease well, but requires careful rinsing to avoid sticky residue.
- 🦷 Toothpaste: contains mild abrasives, ideal for local cleaning of yellow stains on white plastic.
Professional household chemicals: what to choose
If traditional methods do not seem effective enough or you prefer ready-made solutions, the market offers a wide range of specialized tools. When choosing, it is important to pay attention to the labeling: the product must be intended specifically for kitchen surfaces or refrigerators. Universal sprays for plumbing may contain too aggressive components.
Sprays based on surfactants (surfactants) cope well with grease and protein stains. They are easy to use: just apply foam, wait a few minutes and rinse. However, such products often have a strong chemical odor that takes a long time to dissipate. After chemical treatment, the refrigerator must be ventilated with the door open for at least 2-3 hours.
⚠️ Attention: It is strictly forbidden to use chlorine-containing products (for example, “Whiteness”) to wash colored plastic or plastic with a pattern. Chlorine can cause an irreversible reaction, changing the color of the surface or making it dull.
There are also special ones wipes for household appliances with antibacterial impregnation. They are convenient for express cleaning, but they may not be enough for general cleaning of a heavily soiled refrigerator. For difficult cases, it is better to purchase a dishwashing gel with enzymes that breaks down organic residues.
Removing complex contaminants: yellowness and mold
The biggest problem for equipment owners is the appearance of a yellow coating on white plastic. This occurs under the influence of ultraviolet radiation, temperature changes and fat oxidation. If simple washing does not help, you can use more radical but safe methods.
Hydrogen peroxide is often used to bleach plastic. Soak a cotton pad in a 3% peroxide solution and thoroughly wipe the yellowed areas. To enhance the effect, you can leave a wet compress for 10-15 minutes. This method is especially good for plastic screens and drawers.
Mold is a red flag. Fungal spores can penetrate deep into the structure of the plastic. If you find blackheads, regular washing may not help. In this case, it is necessary to treat the surfaces with a vinegar solution or special antifungal agents. After treatment, the refrigerator should be completely dry.
The table below compares the effectiveness of various anti-pollution agents:
| Type of pollution | Soda | Vinegar | Alcohol | Special. chemistry |
|---|---|---|---|---|
| Fat plaque | Average | High | Low | High |
| Mold | Low | High | Average | High |
| Yellowness | Average | Low | Average | Average |
| Odors | High | Average | Low | Low |
How to eliminate unpleasant odors
Even after thorough washing, the smell may persist if it is absorbed into plastic parts. In this case, mechanical cleaning is powerless; adsorption is required. The easiest way is to place an open container with activated carbon, ground coffee or soda inside the chamber.
Modern refrigerators, such as Samsung or Whirlpoolare often equipped with built-in deodorization systems. Make sure the filter is not clogged and requires replacement. If there is no built-in system, you can use special odor absorbers in the form of eggs or capsules, which are sold in hardware stores.
It is important to check the drainage hole. Often the source of the smell is hidden not on the shelves, but in the condensate drain, which is located on the back wall.
