Maintaining perfect cleanliness inside refrigeration chamber is a task that often causes controversy among housewives and owners of household appliances. Many people are wondering whether it’s worth using additional coatings on the shelves at all, or whether it’s enough to just wash the glass regularly. Refrigerator mats They are becoming an increasingly popular solution, as they not only protect the surface from scratches, but also simplify the cleaning process.
However, the wrong approach to choosing or arranging such accessories can disrupt circulation of cold air, which will negatively affect the operation compressor and safety of products. It is important to understand the physical processes occurring inside the chamber before covering the entire usable area.
In this article we will look in detail at what materials are safe for contact with food, how to avoid fogging and why some types of coatings are absolutely not suitable for certain areas of the refrigerator.
Why are protective coatings needed on the refrigerator? shelves
The main function of mats is to create a barrier between products and the glass or plastic surface of the shelf. Glass partitions in modern models, such as Bosch or LG, are quite durable, but are susceptible to microcracks from temperature changes or pinpoint impacts.
The use of linings helps prevent the spreading of liquids. If a jar of jam breaks or a carton of milk leaks, you just need to remove and wash the mat itself without defrosting the entire unit. This significantly saves time and preserves temperature conditions inside the chamber.
⚠️ Attention: If the mat fits too tightly to the walls of the refrigerator, it can block the ventilation holes located on the back panel, which will lead to the formation of ice.
In addition, soft materials reduce noise levels when you place heavy pots or glass jars. The sound is muffled and significantly less is transmitted to the body. This is especially true for refrigerators installed in studio apartments or near a residential area. vibration much less is transmitted to the body. This is especially true for refrigerators installed in studio apartments or near the living area.
Choosing the right material for inserts
The market offers many options, but not all of them are equally useful. The most common material is silicone. It is inert, does not absorb odors and is easy to clean. Silicone mats often have a corrugated surface, which prevents bottles from slipping.
The second popular option is polyethylene foam. It is cheap and light, but over time it can absorb grease and turn yellow. For food purposes, you need to choose only certified products that are marked about the safety of contact with food.
- 🧪 Silicone - durable, withstands temperatures from -40 to +200 degrees, easy to clean.
- 🛡️ Polypropylene - hard, holds its shape well, but can crack with strong cooling.
- 🌿 Natural rubber is environmentally friendly, but may have a specific odor in the first days of use.
- 📦 Foam materials are cheap, but short-lived, prone to deformation.
When choosing, you should pay attention to the texture of the surface. Smooth mats are easier to wipe clean, but slippery vegetables stand on them worse. Corrugated models hold objects better, but dirt can accumulate in the recesses, which is more difficult to wash out.
Rules for laying rugs in different zones
Not all shelves in the refrigerator are the same, and the approach to protecting them must be individual. On the upper shelves, where prepared meals and dairy products are usually stored, it is important to ensure maximum tightness of the lining.
In the freshness zone, where the temperature is close to zero, materials can behave differently. Some plastics become brittle and rubber becomes too hard. Here it is better to use special antibacterial coatings designed for low temperatures.
The lower part of the refrigerator, where vegetables and fruits are often stored, requires special attention. Here the mats must be perforated so that air can circulate freely around the products, preventing them from rotting.
☑️ Correct placement of the mat
When laying, it is important to leave small gaps at the walls. This rule is relevant for all models, be it old Atlant or new Samsung. The air should move freely along the contour of the chamber.
The influence of rugs on the operation of the refrigerator
Many users do not think about the fact that excess objects inside the chamber affect heat transfer. The refrigerator works on the principle of heat removal, and if the air circulation is impaired, thermostat it may give incorrect readings.
A too thick layer of insulation on the shelf can create a “thermal cushion”. Products on such a shelf will cool more slowly, which will shorten their shelf life. This is especially critical for meat and fish products.
| Coating type | Thermal conductivity | Influence on cooling | Recommended zone |
|---|---|---|---|
| Thin silicone (1 mm) | Low | Minimum | All shelves |
| Foamed polyethylene (3 mm) | Medium | Noticeable slowdown | Door, upper shelves |
| Thick rubber (2 mm) | High | Absent | Lower drawers |
| Fabric linings | Very high | Severe disturbance | Not recommended |
If you notice that the refrigerator has started to turn on more often or work longer, try temporarily removing all the rugs and see if the situation changes. This will help diagnose a problem with air circulation.
Myth about energy saving
There is an opinion that mats help the refrigerator save electricity by keeping it cold. This is not true. The refrigerator cools the air, not the items on the shelf. Excess layers only complicate heat transfer, forcing the motor to work harder.
Hygiene and care of protective coatings
Mags themselves become a place for bacteria to accumulate if they are not taken care of. The porous structure of some materials is ideal for the growth of microorganisms and mold, especially in conditions of high humidity.
You can wash silicone products with hot water with the addition of soda or a mild detergent. They are easy to clean in the dishwasher unless the manufacturer specifies otherwise. This allows deep disinfection to be carried out regularly.
⚠️ Attention: Do not use chlorine-containing aggressive agents to clean rugs, as they can destroy the structure of the material and make it toxic.
Foamed materials are more difficult to wash. They should not be rubbed with hard brushes, otherwise the surface will fluff up and absorb moisture even more. It is better to wipe such mats with a damp cloth with an antiseptic and dry thoroughly.
The regularity of cleaning depends on the type of product. If you store a lot of raw meat or fish, you should wash the liners weekly. For shelves with drinks and closed cans, one general cleaning per month is enough.
Typical mistakes when using accessories
One of the most common mistakes is the desire to cover absolutely all surfaces with rugs, including the bottom of vegetable drawers. This leads to the fact that condensation is not absorbed and does not evaporate, but accumulates under the products, accelerating spoilage.
Another mistake is using rugs of the wrong size. If the cover is too large, the edges curl upward, creating pockets for dirt. If it is too small, it moves out, and the meaning of its use is lost.
- 🚫 Using carpets for the bathroom instead of food analogs.
- 🚫 Laying several layers of mats on top of each other "for thickness."
- 🚫 Ignoring the refrigerator manufacturer's instructions regarding shelves.
- 🚫 Drying the rugs with a hairdryer or on a radiator, which causes deformation.
Also, do not fix the rugs with tape or glue. At low temperatures, the glue may lose its properties or, conversely, freeze tightly, damaging the shelf coating when trying to peel off the accessory.
Frequently asked questions (FAQ)
Can ordinary kitchen baking mats be used in the refrigerator?
Technically it is possible if they are made of food-grade silicone. However, baking mats are often not sized to fit on standard shelves and can be too thick, making it difficult for air to circulate. It is better to use specialized thin liners.
How often do you need to change the mats in the refrigerator?
Silicone products last for years until they lose their elasticity or become covered with irremovable stains. It is recommended to replace foam materials every 6-12 months, as they accumulate odors and microparticles of dirt in their structure.
Do mats protect glass from cracks when heavy objects fall?
Partly yes, they soften the blow, but do not guarantee 100% protection against the fall of heavy cast iron pans or glass bottles with great height. Their main function is protection from scratches and leaks, and not from mechanical shocks.
Do colored mats affect the safety of products?
Color does not have a direct effect on the chemical composition of products if safe dyes are used. However, light-colored rugs are better, since dirt is immediately visible on them, which encourages more frequent cleaning and maintaining hygiene.
