Modern refrigerators, be they premium models Samsung or reliable ones Indesit, require regular care to maintain perfect hygiene. Over time, fatty deposits accumulate on the inner walls, which absorbs food odors and becomes a breeding ground for bacteria. Many housewives are looking for an alternative to aggressive household chemicals, which can leave toxic traces in contact with food.
The optimal solution in this situation is to use citric acid. This is an affordable, safe and highly effective product that does an excellent job of removing grease, scale and unpleasant odors. Unlike vinegar, it does not have a strong odor, and unlike chlorine-containing products, it is absolutely safe for food surfaces.
In this article we will look in detail at how to properly prepare the solution, what proportions to follow for different types of stains and how to avoid common mistakes when cleaning. You will learn why this method is preferred by professional cleaners and how to return your refrigerator to its factory whiteness without harming the plastic.
Advantages of citric acid over household chemicals
The use of synthetic detergents is often associated with the risk of chemical odors, which take a long time to disappear and can be transferred to products. Citric acid is an organic compound that does not leave toxic traces. This is especially important for food storage rooms, where the temperature promotes condensation of substances on the walls.
In addition to safety, it is worth noting economic efficiency. A packet of acid costs mere pennies, and is enough for several general cleanings. At the same time, specialized sprays for refrigerators can cost tens of times more, although they are often based on the same surfactants and flavors.
- 🍋 Completely natural composition, safe in case of accidental contact with food.
- 💰 Extremely low cost of processing compared to branded chemicals.
- 💧 No pungent odor, which is characteristic of vinegar solutions.
- 🦠 Powerful antibacterial properties that suppress the development of mold.
It is important to understand that acid environment effectively destroys fatty molecules and mineral deposits. This makes it easy to remove old stains that are difficult to wipe off mechanically, without the risk of scratching glossy plastic or glass shelves.
⚠️ Attention: Despite its natural origin, a concentrated acid solution can cause irritation to the mucous membranes of the eyes. When working with powder, avoid inhaling it and getting into your eyes.
Necessary tools and preparation of solution
Before starting the procedure, it is necessary to properly prepare the workplace and equipment. You will need a mixing bowl, a sponge with an abrasive side and a soft side, and dry microfiber cloths. For hard-to-reach places, such as seals and corners, it is convenient to use a soft toothbrush.
The proportions of the solution depend on the degree of contamination. For regular preventive cleaning, a weak concentration is sufficient, while to remove yellowness or grease, a more saturated composition will be required. The water should be warm, but not hot, to speed up the dissolution of the crystals.
| Type of contamination | Concentration (per 1 liter of water) | Exposure time |
|---|---|---|
| Prevention and fresh stains | 1 teaspoon spoon | 5-10 minutes |
| Fat deposits and drops | 1 tablespoon | 15-20 minutes |
| Yellowness of plastic and old fat | 2 tablespoons | 30-40 minutes |
| Descaling (drainage) | 2 teaspoons | Flow method |
It is better to use the prepared solution immediately, so as during long-term storage it does not lose its properties, but can become contaminated with dust. To wash large surfaces, it is convenient to use a spray bottle, which allows you to evenly distribute the product.
Step-by-step instructions: how to wash the inner walls
The cleaning process begins with the complete emptying of the refrigerator compartment. All products, shelves and drawers must be removed. It is better to wash removable elements separately in a sink or basin, where you can use hotter water and soaking.
Apply the prepared solution to the inner walls of the refrigerator. If the dirt is strong, let the product work. Active time The effect of acid allows you to soften even dried-on food debris. Do not rub immediately, let the chemical reaction pass.
☑️ Algorithm for cleaning the chamber
After waiting, thoroughly wipe the surfaces with a sponge. Movements should be circular, without strong pressure. Pay special attention to the corners and joints of panels, where dirt most often accumulates. Then wipe everything with a clean, damp cloth to remove any remaining acid and dissolved grease.
The final step is to thoroughly wipe it dry. A humid environment promotes the growth of bacteria, so don't be lazy about using a dry towel. After this, the refrigerator door should be left open for 15-20 minutes to ventilate.
⚠️ Attention: Do not use metal brushes or hard scrapers to clean the interior plastic. Citric acid will soften the dirt, and mechanical action will be unnecessary and can damage the surface.
Removing yellowness and old stains from plastic
Over time, white plastic in refrigerators may acquire a yellowish tint. This occurs due to oxidation of the material under the influence of fats and foods. Citric acid can work wonders in such cases, returning surfaces to their original appearance.
To combat yellowness, you will need a more concentrated solution or the use of gruel. Mix the acid crystals with a minimal amount of water to form a thick paste. Apply this mixture directly to the yellow areas and leave for a long time.
In some cases, if the yellowness is caused not only by fat, but also by a change in the structure of the plastic, complete color restoration may not be possible. However lightening it will be noticeable. It is important not to leave the acid on colored plastic or rubber seals for too long, so as not to dry out the material.
Can acid be used for colored plastic?
Use concentrated acid on colored plastic with caution. Although it is less harsh than bleach, prolonged exposure may cause the paint to fade. Always test the product on an inconspicuous area.
After the paste procedure, be sure to thoroughly rinse off any remaining product. It is advisable to wipe the treated areas with water adding a drop of mild detergent to neutralize, and then again with clean water.
Cleaning the rubber seals and drainage hole
The rubber seal around the perimeter of the door is the place where mold and black dirt most often settle. The porous structure of rubber is ideal for the accumulation of bacteria. The acid here acts as an excellent antiseptic.
Carefully bend the seal and wipe it in the folds with a brush dipped in the solution. Do not pull the rubber too hard to avoid damaging the mount. Regular treatment of the seal extends its service life and ensures a tight fit of the door.
The drainage hole located on the back wall requires special attention. It is through this that the condensate drains. If it becomes clogged, water will begin to accumulate inside the refrigerator. You can clean it with a cotton swab or soft wire, after first pouring a little acid solution into it.
- 🧼 Use cotton swabs to clean the folds of the seal.
- 🌊 The drainage solution must be liquid in order to flow freely.
- 🚫 Do not use sharp objects to pick at the drainage channel.
After cleaning the drainage, it is recommended to pour about 50 ml of clean water into the hole to make sure that it flows freely into the compressor pan.
Cleaning external surfaces and removing stickers
The outside of the refrigerator also requires care. Metal surfaces (stainless steel) and painted metal can be washed with a solution of citric acid, but with a lower concentration, so as not to damage the protective coating.
Old stickers, price tags or traces of tape are often a particular problem. Citric acid perfectly dissolves the adhesive base. Apply a concentrated solution or slurry to the sticker, wait 10-15 minutes, and it will be easily removed with a plastic spatula or card.
For stainless steel surfaces, it is important to wipe them along the fibers. This will prevent micro-scratches and maintain an aesthetic shine. After washing, be sure to polish the surface with a dry cloth.
⚠️ Attention: If you have a refrigerator with a coating Fingerprint Free (anti-print protection), use only soft sponges and weak solutions so as not to erase the special coating.
Frequently asked questions (FAQ)
Is it possible to wash glass shelves with citric acid?
Yes, glass is chemically inert and perfectly tolerates the effects of acid. This is even preferable, since the acid removes fatty deposits, which often remain on the glass even after washing with water.
Is citric acid dangerous for aluminum parts?
The acid can react with aluminum, causing it to darken or oxidize. If your refrigerator has exposed aluminum elements (rare in modern models), it is better to wipe them with neutral agents or thoroughly and quickly wash off the acid solution.
How often should you carry out general cleaning?
It is recommended to carry out complete defrosting and cleaning using an acid solution every 3-6 months. This depends on the load of the refrigerator and the type of food stored.
Will citric acid replace defrosting?
No. Citric acid is a cleaning agent, not a refrigerant. Before cleaning, the refrigerator must be defrosted naturally or using special modes, if provided by the model.
