An unpleasant odor in the refrigerator can ruin anyone’s appetite and mood to the hostess. This often happens due to a forgotten product, spilled soup, or violation of storage rules. In such situations, aggressive chemicals may be unnecessary, because there are food products on the shelves.
Baking soda is a universal and safe remedy that can be found in every kitchen. It effectively neutralizes odors without leaving toxic traces. Sodium bicarbonate works as a soft abrasive and a powerful adsorbent, absorbing volatile aroma molecules.
Before taking radical measures, it is worth trying this accessible method. It is suitable for any model, be it old ZIL or modern LG No Frost. Let's look at the process in detail.
Reasons for the appearance of persistent aromas
Understanding the source of the problem is half the success. Most often, the stench is caused by expired products that may have been lost in the far corner. Also caused by spilled liquids that have been absorbed into plastic seals.
In system refrigerators No Frost the smell may come from the drainage system. If water stagnates there or food gets in, the process of rotting begins. In conventional models, the cause is often frozen ice that has absorbed aromas.
⚠️ Attention: If the smell resembles chemicals or burnt plastic, using soda will not help. It is necessary to check the serviceability of electrical components and wiring.
It is important to consider the material of the internal shelves. Glass and metal smell less, but plastic and rubber seals tend to accumulate odors. Porous surfaces require more careful processing.
Preparation for cleaning the refrigerator
The effectiveness of the procedure directly depends on the quality of preparation. You can’t just sprinkle baking soda on top of the stains. First, you need to empty the chambers of all products.
It is recommended to prepare a container for defrosting in advance, if the model requires it. For modern units with a system Total No Frost this step can be skipped, but it is still worth disconnecting the device from the network.
You will need the following tools:
- 🧽 Sponges of different hardness to remove different types of contaminants
- 🧴 Spray gun for application solution
- 🧣 Dry microfiber wipes
- 🥣 Bowl for preparing cleaning paste
Be sure to remove all removable elements: shelves, drawers, egg trays. It is more convenient to wash them separately in the bathroom under running water. Temperature conditions When washing, it should be comfortable so that the glass does not burst from the drop.
☑️ Preparation for cleaning
Preparing a cleaning solution from soda
Soda effective both in dry form and in the form of a solution. For general cleaning, a concentrated mixture is best suited. The proportions are simple: one tablespoon of powder per liter of warm water.
If the dirt is old, you can make a paste. To do this, mix soda with a small amount of water until it becomes thick sour cream. This mixture works better on grease stains.
⚠️ Attention: Do not use hot water to prepare the solution if you are going to wash glass shelves. A sharp change in temperature can lead to cracks.
To enhance the effect, you can add a few drops of essential oil to the solution. However, tea tree oil has its own antiseptic property, which will make cleaning more effective against bacteria.
Technology for washing internal chambers
The cleaning process must be systematic. You need to start from the top of the chamber, gradually working your way down. This will prevent re-contamination of already washed areas.
Apply the solution to the sponge and thoroughly wipe all surfaces. Pay special attention to corners and joints where dirt most often accumulates. For hard-to-reach places, use a soft toothbrush.
The table below shows how soda affects different types of stains:
| Type of stain | Effectiveness of soda | Recommended exposure time |
|---|---|---|
| Fresh juice stains | High | 5-10 minutes |
| Old fat | Medium (needs paste) | 20-30 minutes |
| Mold | High (antiseptic) | 15 minutes |
| Scale | Low (acid needed) | Not effective |
After treatment, be sure to wipe the surfaces clean with a damp cloth. Residues of soda deposits may be noticeable on dark plastic. Thorough rinsing guarantees the absence of white stains.
Removing odor from the drainage system
If the odor remains after a complete wash, the problem may be in the drainage system hole. It is located on the rear wall and serves to drain condensate. A blockage here causes stagnation of water and the appearance of mold.
For cleaning, use a soft brush or special wire. Carefully insert it into the hole and clean the channel. Then pour in the soda solution with a syringe.
This action will help disinfect hidden cavities. In models with Dynamic Cooling access to the drainage may be limited, so proceed carefully so as not to damage the internal mechanisms.
- 💧 Pour 50 ml of solution into the hole
- 🧹 Gently clean the channel with a brush
- 🌬️ Blow out the hole (if there is access)
After the procedure, let the system dry. Turning on the refrigerator into the network is possible only after complete evaporation of moisture.
Soda as an odor absorber on a permanent basis
After cleaning is completed, soda can be used as a freshener. Pour the dry powder into an open container and place it on a shelf. This “trap” needs to be changed once a month.
There is a method with activated carbon, but soda is more accessible. It continues to work until it is saturated with moisture and odors. To enhance the effect, add ground coffee to the powder.
Alternative methods of use:
- 🍞 A piece of black bread soaked in soda solution
- 🍋 A slice of lemon, sprinkled with powder
- 🧻 Cotton discs soaked in concentrate
Such measures will help maintain freshness between general cleanings. This is especially true for families with children, where the risk of spilling something is high.
Prevention and storage rules
To avoid having to frequently resort to emergency cleaning, follow the storage rules. All products must be packaged. Use containers with tight lids or cling film.
Check your supplies regularly. Throw away spoiled items immediately, without waiting for the smell to appear. Wipe the shelves with a damp cloth once a week.
⚠️ Attention: Do not store hot foods in the refrigerator. This creates condensation, which promotes the growth of bacteria and the appearance of mustiness.
Compliance with the commodity neighborhood is also important. Do not store fish, meat and prepared foods in close proximity to each other without airtight packaging. Cross contamination Flavors are a common problem.
Can you mix baking soda with vinegar for cleaning?
Mixing baking soda and vinegar causes a hissing reaction. This is effective for cleaning pipes, but for cleaning the refrigerator it is better to use these products separately. First, soda (as an alkali) removes grease, then vinegar (an acid) disinfects and adds shine. It makes no sense to mix them in one container for cleaning shelves, since they neutralize each other.
Is baking soda safe for plastic boxes?
Yes, baking soda is absolutely safe for all types of food-grade plastic. It does not cause corrosion and does not emit harmful substances. Unlike chlorine-containing products, soda will not change the color of the plastic or make it brittle.
What to do if the smell remains after cleaning?
If thorough washing with soda does not help, the source of the smell may be hidden. Check the space behind the rear panel (if the model allows it), the condition of the seals for microcracks with mold, or the drainage hose. In rare cases, the smell may come from burnt wiring insulation.
How often do you change the container with soda to absorb odors?
It is recommended to change an open container with dry soda, which acts as an absorber, once every 30 days. Over time, the powder cakes and ceases to effectively absorb aromas. If you use soda with essential oils, you should change the mixture more often as the aroma fades.
