Hygiene of the refrigeration chamber is not only a matter of aesthetics, but also a guarantee of the safety of the products you use every day eat. Many housewives and owners are faced with a problem when, after defrosting or routine cleaning, an unpleasant odor, sticky residue, or, worse, moldy spots remain on the walls. Incorrectly selected household chemicals can ruin the plastic case, make it cloudy, or even damage the door seals.
In this article we will look at what professional and folk remedies can safely clean internal surfaces, rubber seals and hard-to-reach places. You'll learn how to eliminate lingering food odors and restore the white color to yellowed plastic without using harsh abrasives.
The key is to understand the material of the inner walls. Modern refrigerator plastic (most often ABS plastic or polystyrene) is sensitive to acids and solvents. The use of unsuitable compounds can lead to microcracks in which bacteria can subsequently multiply. Therefore, the choice of cleaning agent must be conscious and careful.
Preparing for washing and defrosting the unit
Before you start looking for the answer to the question of how to clean the inside of the refrigerator, you need to properly prepare the device for the procedure. It is strictly forbidden to wash a working unit, since a sharp temperature change when warm water comes into contact with cold plastic can cause deformation or cracks. First, you need to completely defrost the chamber by removing all the food and removing the shelves.
The optimal solution would be to leave the doors open for 2-3 hours so that the pieces of ice melt naturally. If time is short, you can use a hairdryer, but you should direct the stream of hot air very carefully, without lingering long on one section of the plastic. After the water has drained, wipe the bottom of the chamber with a dry rag.
⚠️ Attention: Never use a knife or other sharp objects to chip ice. Mechanical damage to the evaporator or plastic casing will lead to expensive repairs or refrigerant leakage.
It is better to take out removable elements such as glass shelves and plastic containers and wash them in the bathroom under running water. This will allow you to thoroughly process them on all sides and avoid large amounts of dirty water getting inside the refrigerator body. While they dry, you can focus on the inner walls.
Folk remedies for safe cleaning
Home recipes are often more effective than aggressive chemicals, especially when you need to decide how to clean the smell from the refrigerator. The leader among safe products is regular baking soda solution. It perfectly disinfects, removes greasy deposits and neutralizes odors.
To prepare the solution, dilute 2 tablespoons of soda in 500 ml of warm water. Use the resulting liquid to wipe all surfaces with a soft sponge. Baking soda acts as a mild abrasive, so do not rub the plastic too vigorously to avoid leaving micro-scratches. After treatment, be sure to rinse off any remaining product with clean water.
Another powerful remedy is table vinegar. It is ideal for descaling and disinfection. Mix vinegar with water in a 1:1 ratio. The solution will not only clean surfaces, but will also kill most bacteria. However, vinegar has a pungent odor that quickly disappears, but can be unpleasant during the cleaning process.
- 🍋 Citric acid: perfectly dissolves fat and leaves a fresh citrus aroma, safe for all types of plastic.
- 🍞 Brown bread: helps remove the smell of burning or fish if you spread the pieces in the chamber overnight after washing.
- ☕ Ground coffee: works as a natural absorbent, absorbing foreign odors for several days.
- 🧼 Laundry soap: soap shavings are dissolved in warm water to wash heavily soiled areas, but requires careful rinsing.
If old stains, you may have to repeat the procedure several times or leave a damp cloth with a solution on the stain for 10-15 minutes to soften the plaque.
Professional household chemicals for refrigerators
If you prefer ready-made solutions, the market offers specialized sprays and gels. They are designed with food chambers in mind and often contain antibacterial ingredients. When choosing a product, look for the mark “for refrigerators” or “food grade plastic.”
Sprays based on surfactants (surfactants) are popular, which do not require rinsing with water, although experts still recommend wiping surfaces with a damp cloth after using them. Such products effectively break down fat and protein contaminants.
Particular attention should be paid to products in the form of foam. They are convenient for vertical surfaces, since they do not flow down immediately, but work over the entire area of application. Foam cleaners often contain fragrances that mask the smell of chemicals, but make sure they are safe when in contact with food.
☑️ Criteria for choosing a product
Avoid using universal cleaning powders with large abrasive particles. They can leave an irremovable dullness on glossy plastic, into which dirt will clog even faster. Gel-like structures or sprays are your best choice.
Removing yellowness and complex stains
Over time, white plastic may acquire a yellowish tint. This occurs due to oxidation of the material, exposure to ultraviolet radiation (if the refrigerator is located near a window) or contact with certain products. Hydrogen peroxide will help restore the original appearance.
Use a 3% peroxide solution, applying it to a sponge or cotton pad. Wipe the yellowed areas until the stain disappears. To enhance the effect, you can mix peroxide with baking soda to a paste, apply for 20 minutes and then rinse.
If the yellowness is caused by a greasy coating that did not wash off the first time, use dishwashing detergent. Apply the concentrated gel to a sponge, lather and treat problem areas. Fat is easily emulsified and removed with warm water.
| Type of contamination | Best product | Exposure time | Features |
|---|---|---|---|
| Greasy coating | Dish gel / Soda | 5-10 min | Requires warm water to rinse off |
| Mold | Vinegar / Peroxide | 15 min | Thorough drying is required |
| Yellowness of plastic | Hydrogen peroxide | 20-30 min | May require repetition |
| Sticky traces (scotch tape) | Vegetable oil / alcohol | 10 min | Test alcohol in an inconspicuous area |
What to do if the yellowness does not go away?
If traditional methods did not help, the plastic may have undergone irreversible chemical changes. In this case, you can use special wipes for cleaning household appliances with a whitening effect, but the result is not guaranteed. Sometimes only replacing the internal plastic panels helps.
Disinfection and elimination of unpleasant odors
Cleanliness is not only the absence of visible dirt, but also the absence of pathogenic microflora. After washing with detergent, it is recommended to disinfect. Chlorhexidine or a weak solution of potassium permanganate is ideal for this, although the latter can stain light-colored plastic, so use it with caution.
If a spoiled product has been in the refrigerator for a long time, the smell can become embedded in plastic parts and rubber seals. In this case, simple washing is not enough. It is necessary to keep the chamber open for at least 24 hours. To speed up the process, you can use activated carbon.
Grind 10-15 tablets of activated carbon into powder and scatter on saucers throughout the chamber for a day. Charcoal is a powerful adsorbent that will pull odor molecules from the pores of plastic. It is also effective to use an ozonizer if it is included with your model.
The rubber door seal requires special attention. It is in its folds that black mold most often settles. Wipe the seal with a cotton swab dipped in vinegar or peroxide, thoroughly cleaning every millimeter of rubber.
Final stage and prevention
After you have decided which means to clean the inside of the refrigerator and have carried out all the procedures, it is important to complete the process correctly. Wipe all surfaces thoroughly with a dry, clean microfiber cloth. Remaining moisture can cause new mold or ice crust to form.
Assemble the refrigerator in the reverse order: install shelves, drawers and containers. Make sure all items are completely dry before closing the doors. You can turn the unit on only after all components have completely dried, especially if you washed the back wall.
To maintain cleanliness, carry out preventive cleaning once every 1-2 months. This will take no more than 15 minutes, but will eliminate the need to do general cleaning and disassemble the structure. Regular maintenance extends the life of equipment.
Use special shelf mats or silicone stands. They take on the main load and are easy to clean in the dishwasher, protecting the main plastic of the chamber from scratches and dirt.
Is it possible to wash the inside of the refrigerator with a window cleaner?
You can use window cleaners, but with great care. They often contain alcohol and ammonia, which can dry out rubber seals, making them brittle. If you have used such a product, be sure to rinse it thoroughly with water and wipe the surface dry. For food-grade plastic, it is better to choose specialized or folk remedies.
How often do you need to defrost a No Frost refrigerator?
The No Frost system does not require regular defrosting to remove ice, as it occurs automatically. However, such a refrigerator needs to be washed at least once a year for hygiene. A complete shutdown and defrosting should be carried out if you notice the appearance of an unpleasant odor or visible dirt that cannot be removed without access to the internal channels.
What cannot be used to wash the inside of the refrigerator?
It is strictly forbidden to use acetone, gasoline, paint thinners, abrasive powders (such as Pemolux in dry form) and hard metal brushes. These substances destroy the structure of the plastic, leave scratches and can be toxic upon contact with food.
How to remove the smell of fish from the refrigerator?
The fish smell is very persistent. After thoroughly washing with vinegar or lemon, place slices of fresh black bread sprinkled with salt or a saucer of ground coffee throughout the chamber. You can also use a tablet of dissolved activated carbon. Ventilation during the day is mandatory.
