Cleanliness inside the refrigerator compartment is not only a matter of aesthetics, but also a guarantee of the safety of the food you consume daily. Many housewives and owners mistakenly believe that it is enough to simply wipe off visible dirt with a damp cloth, but such superficial cleaning often leads to the accumulation of bacteria and the appearance of persistent unpleasant odors, which are then extremely difficult to get rid of. Deep cleaning requires a systematic approach, the correct choice of detergents and an understanding of the materials from which the internal elements of your equipment are made.
In this article we will look in detail at how to wipe the shelves in the refrigerator so as not to damage their coating and ensure perfect hygiene. You will learn which chemicals are safe for food-grade plastic and tempered glass, and which can cause microcracks or clouding of the surface. Regular and competent care extends the life of the appliance, preserving its functionality and appearance for many years.
Before taking active steps, it is necessary to prepare the workplace and tools. The wrong sponge can leave scratches on glossy plastic, which will become an ideal habitat for germs. Therefore, it is important to determine in advance the type of contamination and the material of the shelf in order to choose the most gentle but effective method of exposure.
Preparation for the washing process: safety and removal of elements
The first and most important step before you start wiping the shelves is to completely disconnect the refrigerator from the power supply. This is critical not only for your safety, but also to preserve food that could spoil while you're cleaning. If your refrigerator has a quick defrost function or a special washing mode, it can be activated, but complete defrosting is often necessary for high-quality cleaning of hard-to-reach places.
Remove shelves and drawers with the utmost care, especially if they are made of glass. Sudden temperature changes can be fatal for tempered glass: if you remove a hot shelf from the freezer or, conversely, expose cold glass to hot water, it can burst. Allow the items to reach room temperature naturally before taking them to the sink.
⚠️ Warning: Never try to force a stuck shelf out. Plastic becomes brittle at low temperatures, and excessive force will lead to breakage of the guides or fasteners.
While the shelves are warming up, start freeing up space inside the chamber. Remove all food, sort it and throw away anything that is of questionable freshness. This is the ideal time to conduct an inventory audit. Inspect the door seals and interior walls for mold or sticky residue that may have formed during operation.
Prepare a basin of warm water and soft sponges. Harsh abrasive materials, such as steel wool or the hard side of a regular dish sponge, are absolutely not suitable for cleaning the inside of your refrigerator. They will leave micro-scratches in which grease and bacteria will subsequently accumulate, making future cleaning increasingly difficult.
Choice of detergents: chemistry versus traditional methods
The issue of choosing a detergent is especially acute, since open food is stored inside the refrigerator. Using aggressive household chemicals with strong fragrances can cause food to absorb a chemical smell and their taste will be hopelessly spoiled. Therefore food safety (detergent) is priority number one.
Modern industry offers specialized sprays for cleaning refrigerators, which often have an antibacterial effect and are easily washed off with water. However, many users prefer proven traditional methods, which are no less effective and at the same time completely natural. These include a solution of baking soda, acetic acid in low concentration and lemon juice.
- 🍋 Citric acid Or juice works well with greasy deposits and gives a pleasant fresh aroma, neutralizing the odors of old onions or fish.
- 🧼 Laundry soap (grated and dissolved in water) is a classic remedy that works well washes away stains and is safe for food containers.
- 🧴 Dishwashing liquid is a universal option, but requires very careful repeated rinsing to avoid soap film.
Use is strictly prohibited chlorine-containing bleaches (like “White”) for washing internal plastic parts, if the instructions for your model LG or Bosch do not explicitly allow this. Chlorine can corrode plastic, making it yellow and brittle, and its fumes are harmful to food. Also avoid acetone and other solvents that can melt the surface.
Why should you not mix vinegar and bleach?
Mixing acetic acid and chlorine-containing products leads to a chemical reaction releasing chlorine gas, which is extremely toxic and dangerous to the respiratory tract.
Technology washing shelves made of various materials
The cleaning method directly depends on the material from which the shelf is made. There are three most common types of materials found in modern refrigerators: tempered glass, food-grade plastic, and metal (stainless steel or aluminum). Each of them has its own care technology, ignoring which can lead to damage to property.
Glass shelves are the most hygienic, since glass does not absorb odors and fats. However, they require careful handling. Soak the glass in warm water and detergent for 10-15 minutes to loosen dried-on stains. After this, gently wipe the surface with a sponge, paying attention to the edges where dirt often accumulates. It is best to rinse glass with cool water to avoid streaks.
⚠️ Attention: Do not use hot water (above 45°C) to wash cold glass. Thermal shock can cause instant destruction of the structure of the material.
Plastic boxes and grates are more susceptible to absorbing odors and colors (for example, from beets or turmeric). A paste of baking soda and water is great for cleaning them. Apply the paste to the dirty areas, leave for a few minutes, then scrub gently with a soft brush. Baking soda works as a mild abrasive and an excellent odor absorbent.
Metal elements, such as chrome grilles or slides, can become dull or develop rust stains if not properly cared for. Use special stainless steel polishes or a vinegar solution to remove plaque. After washing, metal parts must be wiped dry to prevent oxidation.
Cleaning the internal walls and hard-to-reach places
While the shelves are drying, you need to pay attention to the interior of the refrigerator compartment. The walls are often covered with a thin film of grease or condensation that mixes with dust. You need to wipe them from top to bottom so that dirty water does not flow over already cleaned areas. Pay special attention to the corners and joints of the panels.
One of the most difficult areas to clean is the system No Frost and ventilation holes. In models with automatic defrosting, dust and lint may accumulate there, which reduces the efficiency of the unit. To clean these areas, use a soft brush or cotton swabs lightly moistened with a cleaning solution.
The rubber seal on the door is a breeding ground for bacteria and mold if it is not taken care of. Black dots in the folds of rubber are fungal colonies. It is best to wipe the seal with a solution of vinegar or hydrogen peroxide, thoroughly cleaning each fold. After treatment, the rubber can be lubricated with glycerin or silicone grease so that it does not dry out and remains elastic.
Don't forget to check and clean the drainage hole, usually located on the back wall at the bottom of the chamber. If this channel becomes clogged, water stops draining and accumulates at the bottom of the refrigerator or under the vegetable drawers. For cleaning, you can use a special flexible brush or soft wire with cotton wool at the end.
☑️ Refrigerator cleaning plan
Drying, assembly and elimination of odors
After thorough washing of all elements, the drying stage begins. This is a critical point: if you pack your refrigerator when it's damp, the inside will quickly develop a musty smell and may develop mold. Leave the shelves and drawers to dry at room temperature until the moisture is completely gone. It is not recommended to speed up the process with a hairdryer, as this can lead to uneven drying and the appearance of stains.
Assemble only when all parts are completely dry. Place the shelves in their places, check the reliability of the fastenings. Now you can pawn your groceries. To prevent unpleasant odors in the future, place a natural odor absorber inside. This can be an open container with activated carbon, soda or a special neutralizer ball.
| Type of contamination | Recommended product | Tool | Features |
|---|---|---|---|
| Greasey coating | Dishing detergent, soda | Soft sponge | Requires warm water |
| Mold on rubber | Vinegar, hydrogen peroxide | Cotton swab | You need to rinse thoroughly |
| Dried drops | Warm water, soaking | Plastic scraper | Do not rub with the metal side |
| Yellowness of plastic | Special cosmetics for plastic | Microfiber cloth | Difficult to remove completely |
If the unpleasant odor still remains, try wiping the internal surfaces with a weak solution of ammonia (in a ratio of 1:10) and leave the refrigerator open for several hours. Ammonia effectively neutralizes even the most persistent organic odors, but requires mandatory ventilation of the chamber before storing products.
Frequency of cleaning and prevention of contamination
How often should you wipe the shelves in the refrigerator? General cleaning with complete emptying and washing of all elements is recommended to be carried out at least once every 3-4 months. However, surface wet cleaning should be done weekly, especially if you notice spilled liquid or crumbs.
Prevention is always easier than dealing with the consequences. Use food containers with lids to store liquid and odorous foods. This will not only keep the shelves clean, but will also extend the shelf life of the products themselves, protecting them from weathering and cross-pollination with odors.
Make sure the defrosting system is working properly. If you notice that there is always water in the refrigerator or the “fur coat” is frozen, this is a signal of a malfunction. In such conditions, shelves get dirty much faster, and bacteria multiply exponentially. Timely repairs will save you from unnecessary work on washing away stubborn stains.
Can the shelves be washed in the dishwasher?
It depends on the material. Glass shelves are generally dishwasher safe as long as they don't have metal surrounds that can rust. Plastic boxes are most often not recommended exposed to high temperatures in the dishwasher, as the plastic can become deformed or become cloudy. Always check the instructions from the manufacturer of your refrigerator model.
How to remove yellow deposits on plastic shelves?
Yellowishness on plastic is often caused by exposure to ultraviolet radiation or oxidation of the material over time. Try making a paste of baking soda and hydrogen peroxide, apply to the surface and leave for an hour. There are also special color restoring sprays for plastic, but they may be less safe for contact with food.
How to remove the smell of fish from the refrigerator?
The fish smell is very persistent. In addition to thoroughly washing all surfaces, place several tablets of activated carbon inside, cut an apple in half, or place an open can of soda. Ventilating the chamber during the day with the door open also helps effectively.
