Regular cleaning refrigeration is not just a matter of aesthetics, but a necessity dictated by sanitary standards and requirements for food safety. In a confined space at low temperatures, bacteria and mold fungi actively multiply, which can cause an unpleasant odor and even spoilage of fresh food. Many owners refrigeration equipment erroneously believe that cold kills germs, but this is not the case, it only slows down their activity.
Before starting the procedures, it is important not only to choose the right detergent, but also to prepare the unit itself for “water procedures”. Incorrectly selected chemicals can damage the plastic casing, cause clouding of transparent acrylic shelves, or destroy the structure of rubber seals. In this article, we will analyze which compositions are safe and effective, and also consider an algorithm of actions for achieving ideal cleanliness without risk to equipment.
The washing process requires a systematic approach: from defrosting to final polishing of surfaces. It is important to understandthat aggressive solvents can leave microcracks in the plastic, in which dirt will subsequently accumulate. Therefore, choosing “how to wash the inside of the refrigerator” becomes a task that requires careful study of the properties of the materials from which your household appliances are made.
Preparation for washing: steps and safety
Before you start looking for a rag and a bucket, you need to properly prepare the unit. The first step is always to completely disconnect the device from the power supply. This is a critical safety rule that should not be ignored, as moisture on the electrical contacts may result in a short circuit or electric shock.
After disconnecting, the chambers should be emptied of all food. If you plan to simply wipe down the surfaces, you can temporarily transfer the food to a bowl of ice or an insulated bag. However, for deep cleaning with defrosting, it is better to remove all contents completely. Remove all removable elements: shelves, drawers, containers for eggs and bottles.
Leave the doors open for a while to ventilate the interior and warm up to room temperature. This is especially true for older models with manual defrosting, where the ice crust can reach a significant thickness. Patience at this stage it will save you effort when removing ice.
☑️ Preparing the refrigerator for washing
Folk remedies for safe cleaning
Home recipes are often more effective than aggressive chemicals, especially when it comes to food chambers. The most popular and safest remedy is baking soda. It perfectly absorbs odors and works as a soft abrasive, removing dirt without scratching the surface.
To prepare the solution, dilute 2 tablespoons of soda in 0.5 liters of warm water. This composition is ideal for washing plastic and glass. If the stains are old, you can make a paste of baking soda and a small amount of water, apply to the stain, leave for 10 minutes, and then rinse.
Acetic acid is another powerful ally in the fight for cleanliness. It disinfects surfaces and removes limescale. Mix table vinegar (9%) with water in a 1:1 ratio. The vinegar solution is absolutely not suitable for marble surfaces (if they are in the decor), but is ideal for plastic and rubber.
- 🍋 Citric acid or fresh lemon juice: perfectly removes greasy stains and leaves a fresh citrus aroma, interrupting the smell of old ones products.
- 🍞 Black bread: an unusual but effective means for removing greasy stains from the inner walls - just rub the dirt with a crust.
- 🦷 Tooth powder: helps clean hard-to-reach places and crevices, acting as a delicate polisher.
Household chemicals: what is possible and what is not
When traditional methods seem insufficiently effective, household chemicals come to the rescue. However, not all under-sink products are suitable for food contact. It is important to avoid chlorine-containing preparations, such as “Belizn” in its pure form, as they can damage the structure of plastic and rubber, making them brittle.
It is safest to use specialized sprays for washing refrigerators, which are sold in hardware stores. They are designed keeping in mind the materials used in the production of home appliances. Dishwashing detergents are also suitable, but they must be washed off very carefully so that the chemicals do not get into the food.
It is strictly forbidden to use abrasive powders for cleaning bathtubs or stoves, as well as solvents such as acetone or gasoline. They will instantly render glossy plastic unusable, leaving matte, irremovable stains on it. Aggressive solvents can also destroy the antibacterial coating, if provided by the manufacturer.
Danger of melamine sponge
Melamine sponge is an effective but controversial remedy. It works as a micro-abrasive (similar to sandpaper). It is dangerous to use it on the glossy plastic of the refrigerator: micro-scratches may appear, into which dirt will get clogged. Use only on matte surfaces with caution.
Technology for washing various surfaces
Different materials require an individual approach. It is best to wipe the plastic walls of the chamber with a soft flannel cloth or microfiber soaked in the selected solution. The movements should be circular, without strong pressure, so as not to damage the thin partitions.
Glass shelves can be washed more intensively using glass cleaners, but make sure that they do not contain high concentrations of ammonia if there are stickers or markings on the glass. Rubber seals on doors are a particular risk area, as this is where mold most often forms.
To clean the seals, use a cotton swab soaked in a vinegar solution or hydrogen peroxide. Carefully go through all the folds. If the rubber is very dirty, you can use an old toothbrush with soft bristles, but be careful not to tear the material.
| Surface type | Recommended product | Tool | Prohibited |
|---|---|---|---|
| Plastic (walls) | Soda solution, special spray | Soft fabric | Acetone, hard brushes |
| Glass (shelves) | Detergent for glass, vinegar | Sponge, napkin | Metal wool |
| Rubber (sealant) | Peroxide, vinegar | Cotton swab | Oils, chlorine |
| Metal (outer part) | Polish for stainless steel | Microfiber | Chlorine, abrasives |
Elimination of persistent odors and mold
Sometimes, even after thorough washing, an unpleasant odor remains in the chamber. This may indicate that bacteria have entered the ventilation system or drainage hole. In such cases, simply washing the walls is not enough.
Check the drainage hole, usually located on the back wall closer to the bottom. It could become clogged with mucus or food debris. You can clean it using a special brush wire or a cotton swab dipped in a disinfectant solution.
To eliminate the odor after washing, place adsorbents in the chambers. This can be activated carbon (10-15 tablets in an open container), fresh coffee grounds or a lemon cut in half. Leave them for a day with the doors closed.
⚠️ Attention: If you find black mold on the seals, do not just wash it off. Treat the affected areas with hydrogen peroxide or alcohol. Mold has deep roots, and if it has penetrated the rubber structure, the seal may have to be replaced as the spores will return.
Final processing and drying
After all surfaces have been washed and disinfected, they must be thoroughly wiped dry with a clean cloth. Remaining moisture can lead to the formation of a new ice crust or become an environment for the development of bacteria.
Let the refrigerator stand open for another 15-20 minutes so that the moisture completely evaporates and the odors of cleaning products disappear. Only after this can you install the shelves and drawers in place. Make sure that all removable elements are also completely dry.
Plug in the device only after complete assembly. Do not load food immediately - give the refrigerator 1-2 hours to reach operating temperature. This is especially important for compressors that may have become hot during inactivity.
Frequently asked questions (FAQ)
Is it possible to wash a refrigerator without turning it off? from an outlet?
Technically, a quick wipe can be done, but a full wash using water and detergents is strictly not recommended. Water may leak into the vents or contacts, causing electronic damage or electric shock. In addition, a running compressor will interfere with defrosting.
How often should you wash the inside of the refrigerator?
General cleaning with defrosting and washing all shelves is recommended once every 3-4 months. However, you should wipe down shelves and check food for freshness weekly. If there is a spill of liquid or spoilage of the product, cleaning is carried out immediately.
How to wash the yellow coating on the plastic of an old refrigerator?
Yellowness is often the result of oxidation of the plastic or exposure to nicotine/fat. Try a mixture of hydrogen peroxide and baking soda. Apply the paste to the surface, leave in direct sunlight (or ultraviolet lamp) for several hours, then rinse. For older models, this method may return the original color.
Is it safe to use a steam cleaner?
Using a steam cleaner is possible, but with great caution. High pressure steam can damage thin plastic or peel off decorative elements. In addition, large amounts of moisture are difficult to remove, which will lead to long drying times. It is better to use a steam cleaner only for treating seals and external surfaces.
