The appearance of an unpleasant aroma in the refrigerator compartment is not just a household discomfort, but also a potential threat to products. Odors can be absorbed into plastic, rubber seals and even lining, creating a persistent odor that is difficult to get rid of simply by airing. Proper washing A refrigerator requires not only water, but also an understanding of the nature of the contamination, be it spilled milk or the smell of defrosted meat.
Many Housewives make the mistake of using aggressive chemicals or ignoring the hidden cavities of the unit. As a result, the problem returns after a few days. In order to (drastically) solve the issue, it is necessary to act systematically: from defrosting to final disinfection of hard-to-reach places.
In this article we will analyze professional cleaning algorithms that service center technicians use. You will learn how to neutralize even the most persistent odors without harm to health and equipment.
Primary preparation and defrosting
The first and most critical stage is the complete emptying of the device from its contents. Defrosting - a mandatory process for older models and desirable for modern No Frost systems if the smell is deeply ingrained. Unplug the appliance by unplugging it from the socket.
Remove all shelves, drawers and containers. It is better to wash them separately in the bath or shower using warm water. The plastic ABS or polystyrene from which the internal elements are made is very porous and quickly absorbs odors, so soaking will not help here - mechanical cleaning is required.
Leave the doors open for at least 2-3 hours. If possible, take the unit out onto the balcony or into the yard (in the shade) to ventilate the stagnant air. Ice crust, if present, should thaw naturally.
⚠️ Attention: Never use a knife, hair dryer or hot water to speed up the thawing of ice. A sharp temperature change can lead to microcracks in the evaporator, which will cause freon leakage and expensive repairs.
Selection of effective cleaning products
The range of cleaning products is huge, but not all of them are suitable for the food area. Harsh solvents can damage the plastic or leave a toxic residue. The optimal choice depends on the degree of contamination.
Excellent for regular cleaning and eliminating light odors. folk remedies. They are safe, cheap and often more effective than chemicals. Soda, vinegar and citric acid create an environment unsuitable for the growth of bacteria.
If the smell is caused by biological decomposition (rotten meat, sour milk), more powerful antiseptics will be required. Chlorine-containing products are effective, but require careful rinsing. Specialized sprays for refrigerators contain enzymes that break down organic matter.
| Product | Effectiveness against odor | Safety for plastic | Application features |
|---|---|---|---|
| Baking soda | Medium | High | Solution 2 tbsp. per 1 liter of water, requires rinsing |
| Table vinegar (9%) | High | Medium | Solution 1:3 with water, neutralizes alkaline odors |
| Household soap | Medium | High | Soap shavings in warm water, washes off grease well |
| Citric acid | High | High | Solution 10 g per 1 liter, disinfects and refreshes |
Why can't you use a melamine sponge?
A melamine sponge works as an abrasive. When cleaning the glossy plastic of the refrigerator, it can leave micro-scratches, into which dirt and bacteria will subsequently become clogged, increasing the odor problem.
Algorithm for washing internal surfaces
The cleaning process should go from top to bottom. First, wipe the ceiling of the chamber, then the side walls, shelves, and finally the bottom. This sequence will prevent re-contamination of already washed areas with flowing dirt.
Use a soft sponge or microfiber. Abrasive brushes are strictly prohibited. Carefully go over the corners and joints of the panels. It is in plastic joints most often that mold and bacteria accumulate, emitting a musty odor.
After treating with a cleaning solution, be sure to wipe all surfaces with a clean damp cloth 2-3 times. Cleaning agent residues can themselves become a source of chemical odor or spoil the taste of food.
☑️ Checklist for an ideal wash
Elimination of persistent odors and mold
If standard washing did not help, then the source of the odor has been preserved. This is often a drainage hole. In models with a system No Frost or Low Frost condensation flows into a groove on the rear wall and goes through a tube into a container above the compressor.
If this tube is clogged with mucus or food debris, the process of rotting begins. Air from the drain circulates back into the chamber. To clean, use a soft brush or a long flexible cable (can be purchased at a plumbing store). Rinse the channel with a syringe with warm water and a disinfectant.
⚠️ Attention: When cleaning the drainage hole, do not use metal wires, which can pierce the thin plastic tube inside the housing. This will lead to water getting on the electrics or the floor.
Another hidden enemy is the rubber seal on the door. Black mold and bacteria often grow in its folds (folds). Wipe the seal with a cotton swab dipped in hydrogen peroxide or vinegar solution, thoroughly cleaning each fold.
Specifics of cleaning the No Frost system
Refrigerator owners No Frost often believe that they do not need to wash anything, since there is no ice. This is a misconception. Although the evaporator is hidden, air currents constantly drive bacteria around the chamber. If a bag of meat leaks in the freezer, the smell will spread instantly.
Pay special attention to the ventilation holes on the back wall. Remove the protective plastic grille (if the design allows) and carefully vacuum the area behind it. Dust and small crumbs can accumulate there, which begin to smell when wet.
Deodorization filters, if provided by the model (usually in the premium segment), require replacement every 6-12 months. The carbon filter cannot be restored by washing; it only needs to be replaced with a new one.
Final drying and neutralization
After wet cleaning, it is critical to completely dry the refrigerator. Moisture is an ideal environment for bacteria. Wipe all surfaces dry with paper towels or a dry microfiber cloth.
Leave the doors open for another 10-12 hours (preferably overnight). Only after complete drying and ventilation can you add food. To consolidate the result and prevent the appearance of new odors, use absorbers.
Place open containers with activated carbon, ground coffee or soda on the shelves. These absorbents will act as a trap for odor molecules. Change this “trap” once a month.
How often should you wash the refrigerator?
General cleaning with defrosting is recommended once every 3-4 months. It is better to wipe shelves and drawers with detergent once a month. Spilled liquids must be cleaned up immediately.
How to remove the smell of plastic in a new refrigerator?
The smell of new plastic is normal. Wipe the cameras with a solution of water and citric acid or vinegar. Leave the appliance with the doors open for 2-3 days. You can place activated carbon tablets inside.
Is it possible to wash a refrigerator with bleach?
It is not recommended to use pure chlorine (White) due to toxicity and the risk of damaging the plastic. If there is no other way out (for example, severe mold), use a weak solution, rinse it off thoroughly and ventilate the unit for a long time.
What to do if the smell remains after washing?
Check the drainage hole and seal. If it's clean, the smell may have been absorbed into the body's thermal insulation (foam). In this case, only long-term ventilation (a week) and the use of an ozonizer or professional odor absorbers will help.
