An unpleasant smell in the refrigerator is a problem that every home cook has encountered at least once. The source could be spilled soup, a forgotten piece of cheese, or even factory grease in a new device. This problem cannot be ignored, since odors are quickly absorbed into products, making them unfit for consumption.
To restore freshness to the unit, it is not enough to simply wipe the shelves with a damp cloth. It is necessary to use special detergents or proven folk recipes that will not only clean surfaces, but also neutralize bacteria. In this article, we will look at the best way to wash the inside of the refrigerator so that the smell disappears forever, and how to prevent its appearance in the future.
Before starting the active cleaning phase, it is important to understand the nature of the aroma that has arisen. If this is the result of food spoilage, disinfection will be required. If there is a smell of mold from the drainage hole, the algorithm of actions will be different. The correct choice of cleaning agent depends on the source of the problem.
Preparing for general cleaning of the refrigerator
Before you search how to wash a refrigerator, you need to properly prepare the equipment for the process. The most common mistake is trying to wash the unit while it is running. This is not only ineffective, but also dangerous for the compressor, which may overheat when trying to cool the open space.
First of all, you need to completely empty the interior space. Remove all food, shelves and drawers. If it’s winter outside, you can take the contents out onto the balcony, but in summer you’ll have to use cooler bags or ask your neighbors to temporarily store supplies.
- 🧊 Disconnect the device from the power supply and leave the doors open for at least 30 minutes to defrost.
- 📦 Remove all removable elements: glass shelves, plastic containers, grilles for bottles.
- 🧹 Prepare a basin with warm water, soft sponges and microfiber cloths so as not to scratch the plastic.
While the equipment is defrosting, take care of the removable parts. It is best to wash them in the bathroom under running water using regular dishwashing detergent. This will remove the main layer of grease and dirt, which prevents deodorizing substances from penetrating into the plastic.
⚠️ Attention: Never use a knife or other sharp objects to chip ice from the walls of the chamber. Damage to the internal circuit or evaporator will lead to a freon leak and costly repairs.
After the ice has melted and the water has drained, you can begin choosing a cleaning product.
Folk remedies for eliminating odors
Many users prefer not to use aggressive household chemicals, fearing (residues) of substances on surfaces. In such cases, time-tested folk methods come to the rescue, which often turn out to be even more effective than store-bought analogues.
The leader among natural cleaners is baking soda. This powder has excellent absorbent properties and a mild abrasive effect. To prepare the solution, dilute 2 tablespoons of baking soda in a liter of warm water. Wipe all the inner walls with the resulting liquid.
Another powerful remedy is table vinegar. The acidic environment perfectly neutralizes alkaline odors and kills bacteria. However, vinegar has its own pungent aroma that dissipates quickly. Wipe surfaces with a solution of vinegar and water in a 1:1 ratio, be sure to ventilate the room well during the process.
- 🍋 Citric acid or lemon juice: perfectly removes grease and leaves a fresh citrus aroma.
- 🍞 Brown bread: cut the loaf and place the pieces on shelves overnight so that the bread absorbs unpleasant odors.
- ☕ Ground coffee: a cup of dry coffee, left in the chamber for a day, works as a powerful natural aroma absorber.
⚠️ Attention: Do not mix vinegar and chlorine-containing products (for example, “Whiteness”). The reaction of these substances releases toxic chlorine gas, which is dangerous for the respiratory tract.
If the odor is very persistent, for example, after storing fish or meat, you can use ammonia. Dissolve 10 drops of ammonia in a liter of water and wipe the camera. After such treatment, the refrigerator must be ventilated for at least 2-3 hours.
Professional household chemicals for refrigerators
When traditional methods seem ineffective or deep disinfection is required, it makes sense to turn to specialized products. The modern market offers sprays and gels designed specifically for kitchen appliances.
Such products usually contain surfactants (surfactants) and antibacterial components. They not only dissolve fat, but also create a thin protective film that prevents the adhesion of new contaminants. Popular brands include Domestos, Synergetic, Top House and Electrolux.
When choosing a chemical, pay attention to the labeling. The packaging must indicate that the product is suitable for contact with food or requires careful rinsing. Gels are often more convenient than sprays, since they splash less and adhere better to vertical walls.
| Medication | Type of base | Effectiveness against odor | Necessity of rinsing |
|---|---|---|---|
| Spray for the kitchen (universal) | Chemical | Average | Required |
| Specialized gel for refrigerators | Natural/Chemical | High | Desirable |
| Wet wipes for household appliances | Alcohol | Low (for dust) | Not required |
| Foam cleaner | Chemical | High (for fat) | Required |
The use of professional chemicals requires compliance security measures. Wear gloves and provide fresh air. After treating with any chemical, be sure to wipe all surfaces with a clean, damp cloth 2-3 times to prevent chemicals from getting on the food.
Is it possible to wash a refrigerator with dishwashing detergent?
Yes, you can. Regular dishwashing detergent (Fairy, Sorti and similar) does an excellent job of removing grease and food stains. The main thing is to thoroughly rinse off the foam, as it can give an off-taste to the products.
Removing mold and mildew in hard-to-reach places
If mold has settled in the refrigerator, ordinary washing is not enough. Fungal spores can penetrate microcracks in plastic and rubber seals, from where they are difficult to wash out mechanically. In this case, disinfection is required.
Hydrogen peroxide is considered the most effective and safe remedy against mold. It not only kills spores, but also lightens the affected areas of the plastic. Generously moisten the sponge with a 3% peroxide solution and carefully treat all corners, panel joints and, most importantly, the rubber door seal.
Pay special attention to the drainage hole. It is located on the back wall of the refrigerator compartment, at the bottom. It is there that mucus and black mold often accumulate, which then spreads the smell throughout the entire volume. To clean, use a cotton swab dipped in a disinfectant solution or a special brush.
- 🦠 Wipe the rubber seal with vinegar or alcohol to kill spores hidden in the folds.
- 💧 Clean the drainage hole with a soft wire or long brush, pour a little soda solution there.
- 🌬 After treatment, leave the refrigerator open for 24 hours for complete drying and airing.
If mold has affected the plastic parts deeply and mechanical cleaning does not help, it is better to replace the elements. Plastic becomes porous over time, and fungal micelles can grow inside the material, from where they can no longer be removed.
⚠️ Attention: Do not use chlorine-containing products (bleach) to clean rubber seals. Chlorine makes the rubber hard and brittle, which will lead to loss of door seal and failure of the refrigerator.
Features of cleaning No Frost refrigerators
Owners of equipment with the system No Frost often mistakenly believe that there is no need to defrost and wash such refrigerators. This is wrong. Although ice does not form in the chamber, the air circulation system requires regular maintenance.
The main feature of washing such models is the need to clean the ventilation holes. It is through them that cold air enters the chamber. If the holes are clogged with dust or crumbs, cooling efficiency decreases, and an unpleasant smell of stale air may appear in the system.
When washing the inside of the No Frost refrigerator, it is important not to flood the electronic sensors and fans, which are often located behind the rear panel of the chamber, with water. Use a well-wrung out cloth and try not to pour water directly onto the back wall where the evaporator grilles are located.
☑️ No Frost washing checklist
Also, No Frost models often have a special tray for collecting condensate, which is located above the compressor at the rear of the unit. Water can stagnate in it and “bio-mucus” can multiply. You can get to it by moving the refrigerator aside and removing the back cover (or simply checking the accessibility from the top, depending on the model). It also needs to be washed periodically.
How to maintain freshness after cleaning
After you have successfully completed the question what product to clean the refrigerator, it is important to consolidate the result. Cleanliness inside the chamber depends not only on the frequency of cleaning, but also on proper food storage habits.
Always use closed containers for food. Open pots of soup or chopped onions are the main enemies of freshness. Modern containers with vacuum lids significantly extend shelf life and prevent mixing of odors.
Check your inventory regularly. Make a rule: place new products at the back, and move those purchased earlier to the front. This will help you not to forget anything and not find spoiled vegetables at the bottom of the box a month later.
- 🥩 Store meat and fish only in the freezer or on the bottom shelf in an airtight package.
- 🥛 It is better to keep fermented milk products and cheeses in the door or on the middle shelves, away from raw materials meat.
- 🍞 Bakery products should not be kept in the refrigerator for more than 2-3 days, as they quickly mold in a humid environment.
Don’t forget about external factors. Periodically clean the external ventilation grilles at the back of the refrigerator to remove dust. A clean heat exchanger ensures better operation of the compressor, which indirectly affects the absence of a musty smell inside the system.
Is it possible to wash a refrigerator with soapy water?
Yes, you can. Regular laundry or baby soap dissolved in water removes grease well. However, soap solutions often leave a film that is difficult to wash off the first time, and can give off a specific odor. It is better to use products that do not require thorough rinsing, or add a little vinegar to the water.
How often should you wash the refrigerator?
It is recommended to carry out general cleaning with defrosting once every 3-4 months. Wet wiping of shelves and checking products should be done weekly. If you spill something sticky or odorous (milk, fish), you need to clean it up immediately.
What to do if the smell remains after washing?
If mechanical cleaning did not help, the smell may have penetrated into the thermal insulation layer of the case (this happens when spoiled products are stored for a long time). In this case, professional ozonizers or long-term (up to 2 days) ventilation with fans turned on will help. You can also try zeolite-based odor absorbers.
Is it safe to use a steam generator for cleaning?
You can use a steam generator, but with great caution. Hot steam is excellent at killing bacteria and dissolving grease, but excess moisture can damage electronic components or insulation. Do not direct the steam jet directly at the lamps, sensors and the back wall of the chamber.
