The accumulation of foreign odors, sticky deposits and even visible mold on the walls are inevitable companions to the active use of household appliances, if you ignore regular cleaning. How to wash the inside of the refrigerator so that there is no smell and germs, not every owner knows, because ordinary household products can damage plastic or rubber seals. An incorrect approach to cleaning often leads to the problem returning after a couple of days, and the products begin to become saturated with a persistent “smell” of old fat or spilled milk.
Modern models Indesit, Beko or LG equipped with complex ventilation systems, such as No Frostwhich require delicate handling when washing so as not to disrupt air circulation. In this article we will analyze professional cleaning algorithms that will help restore ideal cleanliness and freshness without harming the technical components of the unit. You will learn which chemicals are strictly prohibited, and which folk methods really work against nasty contaminants.
A correctly carried out procedure will not only extend the life of your equipment, but also protect the health of the family, since in the warm and humid conditions of the refrigerator, bacteria multiply at an incredible speed. Hygiene of internal surfaces is the first step to maintaining the freshness of products, so it is important to do everything actions consistently and thoroughly. Let's look at the stages of preparation and direct cleaning that service center specialists use.
Preparation for general cleaning and defrosting
Before you begin active actions with a rag and sponge, you must completely empty the internal space of products and removable elements. Defrosting is a mandatory step even for systems with automatic moisture removal, since ice can accumulate in hard-to-reach places, which, when melted, will release water and wash away dirt throughout the entire volume. Unplug the appliance and remove all shelves, vegetable drawers, egg containers and bottle holders.
It is best to take removable parts to the bathroom or kitchen to wash under running water using a mild detergent. Plastic and glass are sensitive to sudden temperature changes, so do not place cold shelves directly under hot water - they may crack. Let them sit at room temperature for 10-15 minutes before starting water treatments.
While the removable elements are drying, inspect the inner chamber for large pieces of food, crumbs or spilled liquids. Mechanical cleaning The dry method will remove the bulk of the debris, which, upon contact with water, will turn into a difficult-to-remove mush. Use a soft brush or dry cloth to collect debris from the bottom of the chamber and corners.
☑️ Preparing for washing
Choosing a safe detergent
Question how to wash a refrigerator, is especially acute, since the internal surfaces are in direct contact with food. The use of aggressive chemicals containing chlorine or strong acids can lead to destruction of the plastic structure, the appearance of microcracks and discoloration of the walls. Moreover, the remnants of such products can be absorbed into products, which will make them dangerous for consumption.
The best choice would be specialized sprays for household appliances or proven folk remedies, such as baking soda solution, acetic acid or laundry soap. A solution of baking soda (2 tablespoons per 1 liter of warm water) is the gold standard, as it not only cleans, but also neutralizes acidic odors without leaving toxic traces. For models with antibacterial coating Hygiene Fresh+ or analogues, it is better to use only water or special wipes recommended by the manufacturer.
⚠️ Attention: It is strictly forbidden to use abrasive powders, hard metal sponges and solvents (acetone, gasoline). They irrevocably scratch the plastic and destroy the protective layer, making the surface rough, which will make the dirt rub off even worse in the future.
If you prefer ready-made store-bought solutions, pay attention to the label “safe for food surfaces” and the absence of chlorine in the composition. Dishwashing gels are also acceptable, but they need to be washed off very carefully, as they form a lot of foam and can leave a slippery film that will collect dust.
Step-by-step instructions: how to wash the inside of a refrigerator
The washing process should go from top to bottom so that flowing dirty water does not stain already cleaned areas. Start with the ceiling of the chamber, then wipe the sides, the back panel and only at the very end the bottom. Movements should be smooth, without strong pressure, so as not to damage sensitive controls or temperature sensors if they are located inside.
Pay special attention to the corners and joints of panels, where mold and black deposits most often accumulate. You can use an old toothbrush or cotton swabs soaked in a cleaning solution to clean these hard-to-reach areas. If you find dried-on stains, do not try to scrape them off with a knife - it is better to apply a cloth soaked in warm water to them for 5-10 minutes to soak the dirt.
| Type of contamination | Recommended product | Tool | Exposure time |
|---|---|---|---|
| Fat deposits | Laundry soap solution | Soft sponge | 5-7 minutes |
| Stains from berries/juice | Citric acid solution | Microfiber cloth | Immediately |
| Mold in the corners | Hydrogen peroxide or vinegar | Toothbrush | 10 minutes |
| General contamination | Baking soda solution | Tissue | As needed |
After cleaning all surfaces with clean water, rinse the camera again to remove any remaining detergent. Even if you used safe soda, its crystals should not remain on the walls, as they can crystallize and scratch the food or packaging. Wipe everything dry with a clean cotton cloth or paper towels.
What to do if the smell remains after washing?
If the smell does not disappear after thorough cleaning, it may have been absorbed into the plastic or rubber seal. In this case, long-term ventilation (leave the door open for a day) or the use of odor absorbers (activated carbon, coffee in an open can) will help.
Cleaning the ventilation system and drainage hole
In models with the system No Frost it is critically important to keep the ventilation ducts through which cold air circulates clean. If the openings are clogged with dust or ice chips, cooling efficiency decreases, the compressor is overloaded, and areas of high humidity may appear inside, leading to food spoilage. Gently go over the ventilation grilles on the back wall with a dry soft brush.
The drainage hole, usually located on the back wall of the refrigerator compartment (bottom), requires special attention. It is through this that the condensate flows into the evaporator. If it is clogged, water will accumulate at the bottom of the refrigerator, creating puddles and a favorable environment for bacteria. You can clean it with a special brush, a cotton swab or twisted soft wire.
To disinfect the canal, you can drop a few milliliters of soda or hydrogen peroxide solution there, and then wipe the inlet with a dry cloth. Do not pour water into the hole with buckets or glasses - this may cause moisture to get onto the electrical components or into the compressor area, which will cause a short circuit.
Care for rubber door seals
The rubber seal (cuff) around the perimeter of the door is one of the main sources of unpleasant odors, which is often forgotten. Food debris, juice, condensation and mold fungi accumulate in the folds of rubber. If the refrigerator smells even after washing the internal chambers, in 90% of cases the problem lies here.
Fold the rubber fold and carefully inspect the space under it. Gently wipe the seal on all sides with a rag soaked in a vinegar solution or a special rubber cleaner. Acetic acid perfectly kills mold spores and restores rubber elasticity, preventing it from drying out and cracking.
⚠️ Attention: Never use oils (sunflower, petroleum jelly) or oil-based products to wipe seals. Oil destroys the rubber structure, it becomes sticky, deformed and no longer fits tightly, which is why the refrigerator will start to keep cold worse.
After cleaning, lubricate the rubber parts with a special rubber care compound or simply glycerin to extend their service life. Make sure the door closes tightly and does not require force to slam. If the seal is damaged or severely deformed, it must be replaced, since cleaning will no longer help restore the seal.
Final drying and startup of equipment
The final stage is thorough drying of all surfaces. Humidity is the best friend of bacteria and mold, so not a drop of water should remain inside. Leave the doors open for 15-20 minutes to completely evaporate moisture and ventilate. Make sure that any shelves and drawers that you washed separately are also completely dry before putting them back.
Reassemble the structure in the reverse order: install the shelves, containers and holders. Only after complete assembly and visual inspection can you plug in the refrigerator. It is recommended to load products not immediately, but 1-2 hours after switching on, when the operating temperature has been established inside.
The regularity of such procedures is the key to the absence of problems. It is enough to carry out a light inspection and wipe down of the shelves once a month, and a general wash with defrosting - once every six months or as needed. This approach will allow you to forget about the question of how to remove the smell from the refrigerator and enjoy the freshness of the food.
Frequently asked questions (FAQ)
Is it possible to wash the inside of the refrigerator with dishwashing detergent?
Yes, you can, but with caution. Dish gels are effective at removing grease, but they create a lot of foam and require very careful rinsing, multiple times. Residues may change the taste of foods. It is better to use a soda solution or specialized products.
How often should you wash the refrigerator to avoid odor?
It is recommended to completely defrost and wash it at least 2 times a year. However, it is worth checking weekly for spoiled food and wiping the shelves with a damp cloth if anything has been spilled.
What is the best way to clean the refrigerator from yellow stains?
Yellow stains (often from turmeric, carrots or old fat) work well with a paste of soda with a small amount of water or a weak solution of hydrogen peroxide. Apply the product to the stain, leave for 10-15 minutes, then gently scrub with a soft sponge.
Is it safe to use a steam cleaner to clean the inside?
Use of a steam cleaner is only possible on metal and glass shelves. It is impossible to direct steam at plastic walls, electronic sensors and rubber seals - high temperatures can deform the plastic and break the tightness of the seal.
What to do if a strange chemical smell appears after washing?
Most likely, you did not rinse off the cleaning agent properly. Wipe all surfaces again with clean water and lemon juice or vinegar. Place an open container with activated carbon or ground coffee inside to adsorb residual aromas and ventilate the chamber.
