The appearance of foreign odors in refrigeration is a common problem that every home cook faces. The source could be spilled milk, a stale piece of cheese, or even new plastic from a newly purchased unit. The problem cannot be ignored, since odors are quickly absorbed into products, changing their taste and making the food unfit for consumption.
Before you look how to wash the inside of a refrigerator, you need to understand the nature of the contamination. If the smell is caused by spoiled food, it is enough to carry out a thorough cleaning with available means. However, in cases where there is a smell of mold or sewage, a more serious approach is required using disinfectant compounds. In this article we will analyze all proven cleaning methods.
Different models require an individual approach. For example, Liebherr or Bosch often have complex ventilation systems that also require maintenance. Improper cleaning may damage the camera coating or interfere with the operation of the sensors. Therefore, it is important to follow the sequence of actions and use only proven compositions.
Preparation for cleaning: important steps
The procedure should begin with the complete release of the chambers. Take out all the products, remove shelves, drawers and containers. Defrosting - a mandatory step, even if you have a No Frost system. An ice crust can hide sources of unpleasant odors and interfere with proper cleaning of the walls.
While the shelves are drying, inspect the interior space. Pay special attention to the rubber seals on the doors. It is in the folds of rubber that dirt most often accumulates and bacteria multiply. To clean them, it is better to use a soft brush or a cotton swab dipped in a cleaning solution.
☑️ Preparation checklist
Don't forget to disconnect the unit from the power supply. This is a security requirement that cannot be ignored. Water and electricity are a dangerous combination, especially when you actively scrub surfaces with wet rags.
⚠️ Warning: Never use sharp objects to chip ice. Damage to the evaporator will lead to freon leakage and expensive compressor repairs.
Folk remedies for eliminating odor
Many people prefer to use time-tested home recipes. They are safe, affordable and often more effective than aggressive chemicals. Baking soda is a universal absorbent that not only cleans, but also neutralizes odors. Dissolve two tablespoons of powder in a liter of warm water and wipe all surfaces.
Acetic acid is another powerful tool in the fight for freshness. It perfectly disinfects and kills germs. However, vinegar has its own pungent odor, which can be irritating. To avoid this, after processing, be sure to ventilate the chamber and wipe it with clean water.
Recipe for an ideal solution
Mix 1 liter of warm water, 2 tablespoons of soda and 1 tablespoon of vinegar. This composition degreases and disinfects at the same time.
Citric acid or fresh lemon juice will give the camera a pleasant citrus aroma. An acidic environment is harmful to many types of bacteria. Wipe the walls with a slice of lemon or an acid solution, then rinse with water. This is especially true before downloading new products.
Household chemicals: what to choose in the store
If traditional methods do not seem effective enough, modern chemistry will come to the rescue. Specialized refrigerator sprays are designed to meet food safety standards. They do not require thorough rinsing and evaporate quickly, leaving a light aroma.
When choosing a product, pay attention to the labeling. Products must be labeled as food safe or “for food surfaces.” Conventional kitchen cleaning products may contain toxic components, the vapors of which will be absorbed by the food.
The table below provides a comparison of popular types of products:
| Type of product | Efficiency | Safety | The need for rinsing |
|---|---|---|---|
| Sprays for refrigerators | High | High | Not required |
| Soap solution | Average | High | Required |
| Vinegar solution | High | Average | Desirable |
| Chlorine-containing products | Maximum | Low | Required repeatedly |
Use wet wipes for office equipment or antibacterial wipes for household needs for express cleaning. They are convenient for wiping handles and small dirt, but for general cleaning they will not be enough.
Removing complex odors and mold
It happens that standard washing does not help. If a spoiled product has been left in the refrigerator for a long time, the smell may become embedded in the plastic. In such cases, “heavy artillery” is required. Hydrogen peroxide does an excellent job of removing organic dirt and mold.
Apply a 3% peroxide solution to problem areas and leave for 10-15 minutes. Then wipe thoroughly with a clean cloth. For hard-to-reach areas, such as around shelf mounts, use a spray bottle.
Activated carbon is a powerful natural sorbent. Crush 10-15 tablets and scatter the powder into saucers, placing them inside a closed refrigerator for a day. This will help draw out the smell from the pores of the plastic.
⚠️ Attention: If the smell appears suddenly and resembles the smell of gas or burning, contact a service center immediately. This may indicate a wiring fault or a refrigerant leak.
Cleaning the ventilation and drainage system
In models with the system No Frost the smell may be hidden deep inside. Air circulates through the ventilation ducts, and if mold has settled there, cleaning the walls will not work. It's difficult to get there on your own, but it's worth a try.
Locate the ventilation hole (usually on the back wall). Gently wipe the accessible area with chlorhexidine or alcohol solution using a long brush or cotton swab on a wire. Be careful not to damage the fan blades.
Also check the drainage hole. It is located at the bottom of the rear wall of the refrigerator compartment. A clogged drain is a common cause of musty odors. Clean it with a special soft wire or a cotton swab, then pour in a little warm water to check the permeability.
Preventing the appearance of fuses
The best way to deal with The problem is its prevention. Regular inspection of products will help avoid spoilage. Use airtight containers to store meat, fish and strong-smelling foods like cheese or smoked meats.
Once a month, wipe the shelves with a damp cloth, even if there is no visible dirt. This will take a couple of minutes but will keep it fresh. It is also useful to keep an open box of baking soda or a special odor absorber inside.
Keep an eye on the expiration dates of the products. Even in the cold, bacteria multiply, albeit more slowly. Periodically check the supplies in the far corners of the shelves, where you rarely look.
