Regular cleaning of refrigeration equipment is not just a matter of aesthetics or a pleasant aroma in the kitchen, but is a critical procedure for ensuring food safety. Inside the chamber, where low temperature and high humidity are maintained, an ideal environment is created for the growth of bacteria, such as listeria or salmonella, which can end up on shelves along with raw meat or unwashed vegetables.
Many housewives mistakenly believe that cold kills microbes, but this is not so: low temperatures only slow down their vital activity, but do not completely destroy pathogenic flora. Dirty seals, stagnant water in the drainage hole and crumbs in trays become a source of unpleasant odors, which are subsequently absorbed by fresh products, making them unsuitable for consumption.
Timely and proper cleaning can extend the life of the compressor and the entire cooling system, since a layer of ice or dirt on the heat exchangers disrupts air circulation. In this guide, we will look in detail at how to properly wash internal and external surfaces, what products to use so as not to damage the plastic, and how to get rid of persistent odors forever.
Preparing for general cleaning and defrosting
Before you begin active actions with a rag and sponge, you need to properly prepare the equipment. The most common mistake is trying to wash the chambers while they are on and full of food, which leads to food spoilage and unnecessary load on the compressor.
First, completely empty the refrigerator of its contents. It is better to put all perishable products in a bowl with ice or in a thermal bag if you are planning a long cleaning. Frozen semi-finished products can be temporarily covered with a blanket so that they do not defrost while you are working on the inner walls.
After emptying the shelves, you must disconnect the device from the power supply. This is a mandatory safety requirement and also speeds up the defrosting process. If you have a model with a No Frostsystem, complete defrosting may not be necessary, but turning off the power is still necessary for safe washing.
To speed up the thawing of ice, do not use a knife or other sharp objects, as there is a high risk of damaging the evaporator and causing the unit to fail. It’s better to put a bowl of hot water inside and close the door for 15–20 minutes - the steam will effectively soften the ice crust.
⚠️ Attention: Never try to peel off the ice with a knife or screwdriver! One careless movement can puncture the thin evaporator tube, which will lead to a freon leak and expensive repairs at a service center.
How long does defrosting take?
The time for complete defrosting depends on the thickness of the ice and the temperature in the room. This process usually takes from 2 to 5 hours. Do not use a hair dryer to speed things up, as a sudden temperature change can deform plastic parts or damage seals.
Choosing safe cleaning products
The range of household chemicals is huge, but not all products are suitable for the inside of the refrigerator. Aggressive solvents, chlorine-containing preparations and abrasive powders can damage the plastic coating of shelves and leave toxic traces that then get into the food.
The best choice would be specialized sprays marked “for food surfaces” or proven traditional methods. Baking soda is an excellent absorbent and gentle cleaner that will not scratch surfaces and is safe for children and animals.
Acetic acid also effectively fights grease and bacteria, but requires careful rinsing to avoid a sour taste in foods. To wash external stainless steel surfaces You cannot use products with chlorine, as they cause metal corrosion and stains.
If you prefer ready-made chemical compositions, carefully read the label: the product must be biodegradable and do not contain phosphates. After treating with any chemicals, the surfaces must be wiped with a clean, damp cloth several times.
Step-by-step instructions: how to wash the inside of the refrigerator
The internal cleaning process should be systematic so as not to miss a single corner where bacteria may be hiding. Always start washing from the top shelves, gradually moving down to the vegetable drawers and the bottom of the chamber.
It is better to remove removable elements, such as glass shelves and plastic containers, and wash them in the sink under running water using a sponge. This will allow you to clean them from all sides, including the ends and fasteners that are difficult to reach inside the case.
Wipe the inner walls with a soft cloth or sponge, generously soaked in the selected solution. Pay special attention to corners and joints where mold most often forms. Movements should be smooth, without strong pressure, so as not to damage the internal contour.
☑️ Internal cleaning checklist
The vegetable storage area requires special attention, as rotting plant remains are the main source of ethylene, which accelerates the spoilage of other products. The boxes should be washed with soap, rinsed thoroughly and completely dried before putting them back.
Removing complex stains and grease
Greasy stains from meat, traces of spilled jam or dried splashes of soup require a special approach. Regular rinsing with water will not help here; it is necessary to use products that break down the fatty structure.
For old stains, you can prepare a paste from baking soda and a small amount of water. Apply this mixture to the problem area and leave for 10-15 minutes. The alkaline environment will effectively soften the fat, after which it can be easily removed with a damp cloth.
If there are traces of labels or adhesive tape on the shelves, use vegetable oil or a special spray to remove stickers. The oil is applied to a cotton pad, which is used to wipe off the dirt, after which the surface is degreased with a soap solution.
If raw eggs are broken inside the refrigerator or milk is spilled, you need to act immediately. When dry, protein stains become sticky and difficult to remove, and are also an ideal breeding ground for bacteria.
⚠️ Attention: If you find mold (black or green spots) inside, regular washing may not help. Treat the affected areas with a solution of hydrogen peroxide or vinegar, leave for 10 minutes and rinse thoroughly.
Fighting unpleasant odors
Even after thorough washing, an unpleasant odor may persist in the refrigerator, especially if the food has already spoiled. Simple ventilation often does not work, since the odor molecules are already absorbed into the plastic and rubber seals.
The most effective and safe adsorbent is activated carbon. It is enough to crush 10-15 tablets and pour the powder into a shallow bowl or open box, leaving it on the bottom shelf for 24 hours.
Natural coffee (preferably ground), soda in an open pack, or a slice of black bread also work well with aromas. These substances work as natural filters, absorbing volatile compounds.
It is not recommended to use air fresheners with chemical fragrances, as they can give products an unnatural chemical taste. It is better to use citrus zest or cotton pads soaked in vanilla extract, which will give a light, natural aroma.
If the smell appears suddenly and it is similar to the smell of rotten meat or fish, check the space behind the rear plastic shield (if the design of the model allows it to be removed without violating the warranty), as liquid may have leaked there.
Cleaning external surfaces and seals
The appearance of the refrigerator is the face of your kitchen. Doors, especially in the area of the handles, are constantly in contact with hands, on which grease, dirt and germs can remain. Regular wiping of external panels is necessary to maintain hygiene.
The rubber seals are a critical element that is often forgotten to be washed. It is in the folds of the rubber that dirt accumulates, which over time leads to loss of elasticity, the appearance of cracks and a loose fit of the door.
The rubber bands should be washed with warm water and soap or a weak solution of vinegar. After washing, be sure to dry them with a soft cloth. To prevent the rubber from drying out and cracking, you can lubricate it with silicone grease or glycerin every six months.
For stainless steel surfaces (stainless steel), use only special polishes or microfiber, moving along the metal fibers. Transverse movements will leave noticeable scratches and stains that will spoil the appearance of the equipment.
Table: Comparison of cleaning products
To make it easier for you to navigate the choice of cleaning product, we have prepared a comparison table. It will help you choose the best option for different types of contaminants and materials.
| Product | Effectiveness against grease | Safety for plastic | Odor removal | Recommended frequency |
|---|---|---|---|---|
| Baking soda | Medium | High | High | Monthly |
| Vinegar 9% | High | High | Average | Once a quarter |
| Special. kitchen spray | Very high | Medium | Low | As needed |
| Soap solution | Low | High | Low | Weekly |
| Hydrogen peroxide | Low | High | High (disinfection) | If mold is detected |
Use this table as a cheat sheet when choosing a cleaning method. Remember that regular maintenance requires less effort than dealing with old stains.
Prevention and rules for storing food
In order for the refrigerator to remain clean longer, it is important not only to wash it correctly, but also to properly organize storage. Chaotically arranged products contribute to rapid contamination of shelves and mixing of odors.
Follow the “first in, first out” principle: place new products at the back of the shelf, and push old ones forward. This will help avoid a situation where a forgotten jar with an expired expiration date is found in the far corner.
Be sure to cover all liquid foods, sauces and open canned food with lids or cling film. This will prevent the products from drying out and their aromas spreading throughout the chamber.
Check the contents regularly, at least once a week. Throw away spoiled vegetables, fruits that show signs of rot, and food that has expired. The cleanliness inside the chamber directly depends on what is stored in it.
⚠️ Attention: Never place hot pots or pans in the refrigerator. This not only disrupts the temperature regime and causes the compressor to wear out, but also creates condensation, which promotes the growth of bacteria.
Why do you need a gap at the back wall?
When arranging products, leave a small gap at the back wall of the chamber. This is necessary for free circulation of cold air. If the food blocks the flow, “warm zones” will form in the refrigerator, where the food will spoil faster.
Frequently asked questions (FAQ)
Is it possible to wash the refrigerator without unplugging it?
Technically, you can quickly wash the shelves with the compressor running, but This is not recommended. First, water and electricity are a dangerous combination. Secondly, while you open the wash door, warm air enters, causing the motor to work harder. It is better to spend 10 minutes on defrosting and safe cleaning.
How often should you wash the refrigerator?
General cleaning with complete defrosting and washing the shelves is recommended once every 3-4 months. However, you should wipe the shelves with a damp cloth weekly and throw away spoiled food. External handles and doors should be wiped with a disinfectant daily or every other day.
How to remove the smell of fish from the refrigerator?
The smell of fish is very persistent. First, wash the camera thoroughly with soapy water. Then wipe all surfaces with a weak solution of citric acid or vinegar. After this, leave an open pack of soda or a cup of ground coffee inside for a day. Activated carbon also helps well.
What to do if there is mold in the refrigerator?
Mold is dangerous to health. It is necessary to completely empty the refrigerator and wash all removable parts with hot water and soda. Treat the internal chambers with a solution of vinegar or hydrogen peroxide. Pay special attention to seals. After treatment, thoroughly dry the chamber and leave the door open for several hours.
Is it possible to use a steam cleaner to wash the inside?
Using a steam cleaner inside the refrigerator compartment is highly not recommended. Sudden temperature changes and excess moisture can damage plastic elements, insulation materials and electrical contacts. It is better to use traditional methods using safe liquid products.
