An unpleasant smell in the refrigerator is a problem that every home cook has encountered at least once. Even the cleanest-looking chamber can hide sources of aroma that instantly permeate the food. Most often, the reason lies in spilled soup, a forgotten piece of cheese, or a broken package. This signal cannot be ignored, since bacteria multiply at tremendous speed.
Before searching, how to wash a refrigeratorit is necessary to audit the contents. Often the source of the “amber” is a forgotten vegetable in the bottom drawer or a burst jar of pickles. After removing the source of contamination, you need to choose the right detergent that will not only remove the odor, but will also be safe for food. In this article we will look at professional and folk cleaning methods.
Modern models, be it LG or Indesit, have complex air circulation systems. Odor can linger in hard-to-reach places, such as the drain hole or evaporator grill. Therefore, simply wiping the shelves with a damp cloth is often not sufficient. An integrated approach to disinfection and subsequent neutralization of odors is required.
⚠️ Attention: Before starting any cleaning work, be sure to disconnect the refrigerator from the power supply. This is a safety requirement that cannot be ignored, even if you are just planning to wash the shelves.
Preparing for washing: defrosting and removing elements
Effective odor control is impossible without proper preparation. If you have a model with a No Frostsystem, complete defrosting may not be required, but it is still necessary to disconnect the device from the network for the safety of electrical contacts. Older models require complete defrosting within 10-12 hours. Water flowing down when the ice melts can take away some of the bacteria, but will not completely eliminate the ingrained odor.
After disconnecting, all removable elements are removed from the chamber. Glass shelves, plastic vegetable containers, egg trays and bottle holders need to be removed. It is on plastic and in glass joints that bacteria often accumulate. It is more convenient to wash them separately in the bathroom or under the tap, using hot water and detergent.
☑️ Preparing the refrigerator for cleaning
It is important to let the inner walls of the chamber warm up to room temperature. Washing cold surfaces is less effective as grease stains may not dissolve. In addition, sudden changes in temperature upon contact with warm water can damage the interior coating or glass. Let the equipment stand with the doors open for at least 30 minutes.
Folk remedies: soda, vinegar and ammonia
The most popular question: how to wash the inside of the refrigerator to eliminate the smell without using aggressive chemicals? The leader among folk remedies is ordinary baking soda. It has excellent absorbent properties and a mild abrasive effect. The solution is prepared at the rate of one tablespoon of powder per liter of warm water. Wipe all surfaces with this mixture, then rinse with clean water.
Acetic acid is a powerful weapon against bacteria and mold. Table vinegar 9% is diluted with water in a 1:1 ratio. The pungent smell of vinegar quickly dissipates, taking other aromas with it. However, you should be careful with rubber seals: acid can dry out the material, so it is better to treat them with a more gentle composition or lubricate them with glycerin after washing.
Ammonia (ammonia) does an excellent job of removing old odors, for example, if rotten meat has been sitting in the refrigerator for a long time. The solution is prepared weak: 1 tablespoon per liter of water. Ammonia is toxic, so you need to work in a ventilated area and wear gloves. After treatment, the surface must be rinsed thoroughly, as the remaining product can give the products a chemical taste.
⚠️ Attention: Never mix vinegar and ammonia. When they combine, a dangerous gas is formed that can cause poisoning. Use these products separately at different stages of cleaning.
Household chemicals and specialized sprays
If traditional methods seem ineffective or labor-intensive to you, household chemicals come to the rescue. The market offers many sprays for cleaning kitchen surfaces and refrigerators. They contain surfactants (surfactants) that break down fat and antibacterial components. When choosing a product, pay attention to the “food safe” or “no rinse” label (although rinsing is still recommended).
Specialized refrigerator sprays often contain silver ions or plant extracts that inhibit the growth of bacteria. They are easy to use: just spray the product onto the dirty surface, wait the time specified in the instructions and wipe with a dry cloth. Such products are especially good for express cleaning and removing fresh stains.
When using chemicals, it is important to follow the dosage. Excess chemicals can settle on the walls and subsequently be absorbed into foods, especially butter, cheese and open liquids. After chemical treatment, the refrigerator needs to be ventilated longer than after using soda or vinegar.
Comparison table of cleaning products
To make it easier for you to choose how to clean a refrigerator from odor, we have prepared a comparison table of popular products. It will help assess the effectiveness, safety and labor intensity of each method.
| Medicine | Effectiveness against odor | Safety for products | Labor intensity |
|---|---|---|---|
| Baking soda | Medium | High | Low |
| Table vinegar | High | High | Low |
| Ammonia | Very high | Medium (requires washing) | Average |
| Special. sprays | High | Depends on the composition | Low |
| Laundry soap | Low | High | High |
As can be seen from the table, vinegar and soda remain leaders in the combination of safety and ease of use. Laundry soap, despite its naturalness, can leave a film and a specific odor that is difficult to remove. Specialized sprays are good for regular maintenance, but can be expensive for general cleaning.
Cleaning hard-to-reach places: drainage and seals
It often happens like this: the refrigerator is washed, the shelves are shining, but the smell remains. In 80% of cases, the cause lies in the drainage hole. It is located on the back wall of the chamber and serves to drain condensate. If food or mucus gets into it, a plug forms and the water begins to stagnate, giving off a rotten smell. You can clean it with a cotton swab or a special brush.
How to properly clean the drainage hole
Take a soft wire or a long brush. Carefully insert it into the hole to a depth of 5-10 cm. Move up and down, destroying the blockage. Then pour 50 ml of warm water and soda into it to rinse the channel.
The rubber seal on the door is another breeding ground for bacteria. Dirt, juice from berries and crumbs get stuck in its folds. The seal must be washed thoroughly, bending back each fold. To disinfect rubber, you can use a weak solution of chlorhexidine or hydrogen peroxide. After washing, it is advisable to lubricate the rubber with silicone grease or glycerin so that it does not crack.
In models with the system No Frost the smell may come from the condensate container, which is located on the rear wall outside (usually above the compressor). Getting there is difficult and often requires removing the back cover. If you are not confident in your abilities, it is better to call a specialist, but if the smell is unbearable, access to the evaporator and tray is required. Black mucus may accumulate there - the result of fungal growth.
Neutralization of odor after cleaning
Once you have decided how to clean a refrigeratorand have carried out a thorough cleaning, you need to consolidate the result. Even after washing, there may be a slight smell of detergent or residual aroma from products. For this, odor absorbers (absorbents) are used.
The simplest and most affordable absorbent is activated carbon. It is enough to crush 10-15 tablets and scatter the powder into saucers, placing them on the shelves. Coal has a porous structure and perfectly absorbs odor molecules. It needs to be changed once a month. You can also use silica gel cat litter (in bags), but only if they do not have their own fragrance.
Folk wisdom suggests using rye bread, a cut onion or an open can of coffee. These products do work, but they do have an expiration date. An onion, for example, needs to be changed every 2-3 days, otherwise it itself will become a source of odor. It is better to use ground coffee, since it has a larger contact area with air.
Modern equipment is often equipped with built-in filters. Refrigerators Samsung with function Deodorizer or Bosch with system AirFresh use carbon or zeolite filters. Their lifespan is limited, and if the smell appears in a new, working refrigerator, it may be time to replace the filter cartridge. Replacement instructions are usually found in the user manual.
Prevention: how to maintain freshness for a long time
To prevent the question “how to remove the smell from the refrigerator” from arising too often, it is important to follow the operating instructions. Do not place hot food in the chamber - this disrupts the temperature regime and promotes the growth of bacteria. All products must be packaged: use containers with tight lids, cling film or vacuum bags.
Regular cleaning is key. It is recommended to carry out general washing with disconnection from the network once every 3-6 months. Every week it is enough to wipe the shelves with a damp cloth and check for spoiled products. Pay special attention to the storage area for meat and fish - these are the most “fragrant” products that require double packaging.
⚠️ Attention: If the smell appears suddenly and resembles the smell of gas or burnt wiring, immediately turn off the refrigerator and call a technician. This may indicate a freon leak or an electrical malfunction, rather than contamination.
By following these recommendations, you can keep your refrigerator perfectly clean and fresh. Choosing the right cleaning product and regular maintenance will extend the life of your equipment and keep your family healthy. Remember that the smell is an indicator of the condition of the appliance and cannot be ignored.
Is it possible to wash a refrigerator with soap?
You can use laundry soap, but it leaves a residue that is difficult to wash off and a specific smell. It is better to use liquid dish soap without strong fragrances or specialized products.
How often do you need to change the odor absorber?
Activated carbon is changed once a month, special gel absorbers - as the color or consistency changes (usually 2-3 months), natural products (bread, coffee) - every 2-3 day.
Why does a new refrigerator smell?
The smell of plastic in a new refrigerator is normal. It goes away after the first wash and airing within 2-3 days. If the smell is chemical and pungent, it may be a defect or remnants of factory lubricant.
What should you not wash your refrigerator with?
Do not use abrasive powders (scratch the plastic), chlorine-containing bleaches (can damage the seals and leave an odor), as well as hot water above 40 degrees.
