Keeping food fresh and saving energy directly depends on the tightness of the refrigerator compartment. The main keeper of the cold is sealing rubber, which is adjacent to the metal body along the perimeter. Over time, dirt accumulates on it, which not only spoils the appearance, but also disrupts the tight fit of the sash.
If you do not pay attention to the hygiene of this part, mold begins to multiply in the folds, an unpleasant odor appears, and the material itself loses its elasticity and cracks. Owners of household appliances LG, Bosch or Indesit need to know how to properly care for the seal in order to avoid costly repairs to the compressor due to its constant operation.
In this article we will analyze proven cleaning methods that are safe for rubber and tell you how to return the seal to its original condition softness. Regular maintenance can significantly extend the service life of the unit and maintain an ideal microclimate inside the chambers.
Why does the seal get dirty and what does this lead to
The main reason for the appearance of soot and a sticky layer on the rubber is constant contact with your hands when opening the door, as well as splashes from cooking food and condensation. Moisture in combination with organic residues creates an ideal environment for the development of bacteria. Black plaque on rubber - these are most often colonies of mold fungi, which can be dangerous to the health of household members.
When the seal is dirty, it cannot fit tightly to the body. Microscopic gaps are formed through which cold air escapes. As a result, the compressor is forced to work harder, trying to compensate for the loss of temperature. This leads to increased electricity consumption and accelerated wear of the motor.
⚠️ Attention: Ignoring black spots on rubber can lead to mold penetrating into the structure of the material. In this case, it will no longer be possible to wash it; a complete replacement of the seal will be required.
In addition, the greasy film makes the rubber hard. When the door is opened frequently, kinks and cracks form faster on hard material. This is especially true for models with a No Frostsystem, where temperature changes are more noticeable. Regular cleaning prevents the material from drying out.
How to clean the seal: safe folk remedies
For regular care it is not necessary to buy expensive household chemicals. There are many available products that effectively remove grease and dirt without damaging the rubber structure. Baking soda is one of the best absorbents that can pull dirt out of the pores of the material.
Dissolve one tablespoon of baking soda in a glass of warm water. Dampen a soft sponge or microfiber cloth in the resulting solution. Wipe the seal thoroughly around the entire perimeter, paying special attention to the folds. After treatment, be sure to wipe the rubber with a clean damp cloth to remove any remaining soda.
Another effective remedy is acetic acid. It perfectly disinfects and kills mold spores. Mix table vinegar (9%) with water in a 1:1 ratio. Wipe the contaminated areas with a cotton pad soaked in the solution. Vinegar also helps eliminate unpleasant odors that can be absorbed into rubber.
To remove fresh grease stains, you can use a paste of tooth powder or regular white toothpaste. Apply the product to a soft-bristled brush and gently scrub problem areas. Abrasive particles will gently remove plaque without scratching the surface.
Professional products and chemicals for complex stains
If traditional methods cannot cope with old grease or stubborn dirt, you should turn to specialized cleaning products. Dishwashing gels work well with grease film. Apply a small amount of gel to a damp sponge, lather and treat the seal.
It is important to thoroughly rinse off the detergent, as its residue may cause irritation to the skin of your hands the next time you come into contact with the refrigerator. For disinfection, you can use alcohol wipes for office equipment or a chlorhexidine solution. They quickly evaporate and leave no traces.
- 🧼 Liquid soap for delicate surfaces - removes light stains.
- 🍋 Citric acid - whitens yellowed rubber and disinfects.
- 🧴 Sprays for car care for rubber products - give elasticity.
There are special sprays for caring for rubber, which are often used in the automotive industry. They contain substances that restore the structure of rubber. However, before using it on the refrigerator, be sure to check the composition for the absence of aggressive solvents.
⚠️ Attention: It is strictly prohibited to use chlorine-containing bleaches (for example, pure "Whiteness") and acetone. These substances destroy the molecular bonds of rubber, making it brittle.
How to remove mold and black plaque
The appearance of black dots indicates the development of fungus. You need to fight it immediately, before it penetrates deep into the material. First of all, prepare a saturated solution of laundry soap. Grate the block and dissolve the shavings in hot water until you obtain a thick paste.
Apply the soap mass to the affected areas and leave for 15-20 minutes. Then scrub gently with an old toothbrush. Mechanical action will help remove visible mold colonies. After this, wipe the rubber with a solution of hydrogen peroxide.
☑️ Fighting mold
If the mold has affected the seal deeply, a more radical approach may be required. In some cases, treatment with a steam generator at minimum power helps. A jet of hot steam kills fungal spores in hard-to-reach folds.
After any mold removal procedure, you need to wipe the rubber dry and leave the refrigerator door open for several hours to dry completely. Humidity is the main enemy in the fight against fungus.
How to lubricate the seal for elasticity: choosing a product
After cleaning, the rubber must be protected and its properties restored. Many people wonder how to lubricate the seal to prevent it from drying out. The ideal option is silicone grease. It is inert, does not react with rubber and creates a protective film.
Silicone prevents drying out, restores softness and improves sliding when closing the door. Lubricant can be found in spray or gel form at automotive supply stores. It should be applied in a thin layer on a clean, dry surface.
Glycerin can be used as an alternative. This is an affordable pharmaceutical product that perfectly softens rubber. Apply a little glycerin to a cotton pad and walk around the entire perimeter of the seal. The effect does not last long, so the procedure will have to be repeated more often.
| Medicum | Effect | Frequency of use | Where to buy |
|---|---|---|---|
| Silicone grease | High elasticity, protection | Once every 3-4 months | Auto shop |
| Glycerin | Softening, shine | Once every month | Pharmacy |
| Castor oil | Structure restoration | Once every 2 months | Pharmacy/household goods |
| Special milk | Comprehensive care | According to instructions | Household chemicals |
Some users try to use vegetable oil. Do this strongly not recommended. Organic oils oxidize over time, begin to stick, acquire a rancid odor and attract insects. Use only mineral or synthetic compounds.
What not to do: prohibited substances
The rubber seal is a sensitive element that can be easily damaged by aggressive chemicals. To avoid having to change the part a month after cleaning, remember the list of prohibited products. Solvents (acetone, white spirit, gasoline) instantly corrode the surface.
Abrasive powders for cleaning bathtubs and kitchen stoves leave microscopic scratches. Dirt will accumulate in these grooves even faster, and mold will grow deeper. The surface will become rough and lose its sealing properties.
- 🚫 Aggressive alkalis and acids in their pure form.
- 🚫 Metal brushes and hard scrapers.
- 🚫 Steam cleaners with steam temperatures above 60 degrees.
Also, do not use hot water. Boiling water can deform the rubber, and it will no longer fit tightly to the body. Carry out all procedures using water at room temperature or slightly warm.
⚠️ Attention: Technical characteristics of rubber may vary between different manufacturers. Before using a new cleaning agent, always test it on an inconspicuous area of the seal.
Regular care and damage prevention
For the seal to last for a long time, it is not enough just to clean it once a year. A system is needed. Once a week, wipe the rubber with a damp cloth during general cleaning of the kitchen. This will take a minute, but will prevent a sticky layer from building up.
Once a month, do a deep clean using baking soda or soapy water. And once a quarter, be sure to lubricate the seal with silicone or glycerin. Such a schedule will allow you to forget about problems with tightness.
How to check the tightness?
Press a sheet of paper between the door and the body. If it is pulled out easily and without resistance around the entire perimeter, the seal requires replacement or adjustment. Normally, the paper should be pulled out with force.
Pay attention to the condition of the door hinges. If they sag, the door warps and the seal does not fit evenly. At the bottom it can move away, and at the top it can shrink too much. In this case, cleaning will not help; the hinges need to be adjusted.
When defrosting the refrigerator, do not use a knife or other sharp objects to chip ice from the seal. An accidental cut will compromise the integrity of the part. Let the ice melt naturally or use a hair dryer in cold air mode.
FAQ: Frequently asked questions
Can wet wipes be used for cleaning?
Ordinary cosmetic wet wipes can be used for express cleaning of dust. However, they contain fragrances and alcohols, which can dry out the rubber if used frequently. It is better to choose specialized wipes for household appliances or just a damp cloth.
How often should you lubricate the seal with silicone?
The optimal frequency of treatment is once every 3-4 months. If the refrigerator is in a kitchen with dry air or next to a radiator, you can lubricate it more often, once every 2 months. A dried out sealant is immediately visible by its matte color and small cracks.
What to do if the rubber has turned yellow?
Yellowing is a sign of aging of the material or exposure to nicotine deposits (if people smoke in the kitchen). You can whiten yellowness using hydrogen peroxide or citric acid. If the material has become hard and crumbles, only replacement will help.
Will cleaning help if the door does not close?
If the cause of loose closure is adhering dirt or congealed grease, then thorough cleaning and lubrication will solve the problem. If the seal is deformed, torn or lost its shape, but it does not help, the part will need to be replaced.
