The issue of correct installation of accessories inside the refrigerator compartment is often ignored by users, although the service life of the equipment directly depends on this. Many owners don’t even think twice, believing that their function is purely decorative. However, manufacturers put engineering sense into these products related to thermodynamics and hygiene. which side to lay mats in the refrigerator, believing that their function is purely decorative. However, manufacturers put engineering sense into these products related to thermodynamics and hygiene.
Improper placement of the substrate can disrupt the circulation of cold air, which will lead to uneven cooling of products. Moreover, ignoring the operating instructions often causes condensation or an unpleasant odor. In this material we will analyze in detail the types of mats, their purpose and the correct installation technique for different models of refrigerators.
Modern refrigerators are complex devices where every element matters. Even such a small accessory as a rug on a shelf affects the operation of compressor and the system No Frost. Understanding the principles of operation of your unit will help you avoid unnecessary repair costs.
Main types of mats and their purpose
Before figuring out which side to lay the mat on, you need to determine what kind of material you are dealing with. There are three main types of substrates in modern refrigerators, and each of them performs its own unique function.
The first type is silicone mats. They are flexible plates with a relief surface. Their main task is to prevent dishes from sliding and collect spilled liquid, preventing it from spreading all over the shelf. Silicone is inert, does not absorb odors and is easy to clean.
The second type is textile or fleecy mats. Most often they come with premium models. Their purpose is to create a “cushion” for vegetables and fruits so that they do not wrinkle and remain fresh longer. The fabric can be impregnated with special antibacterial compounds.
- 🌡️ Thermoregulation - some mats help distribute the cold more evenly over the surface of the shelf.
- 🛡️ Glass protection - prevents scratches from the bottom heavy pots or jars.
- 💧 Moisture collection - the relief structure retains melt water from defrosting products.
The third type is absorbent substrates, often found in older models or specialized wine refrigerators. They work like a sponge, absorbing excess moisture. It is important to understand the difference between them, since the installation rules for each type may differ.
Anatomy of a silicone mat: where is the top and where is the bottom?
Silicone mats are the most common accessory, and it is with them that the most questions arise. At first glance, they may seem the same on both sides, but upon closer examination you will notice important differences in the surface structure.
One side of such a rug usually has smooth, glossy texture. This is the front side that comes into contact with the products. The smooth surface makes it easy to remove dirt: just wipe with a damp sponge, and grease or juice will not get stuck in the pores. In addition, smooth silicone is less susceptible to plaque formation.
The reverse side is most often equipped with relief pattern or a mesh. It is this side that the mat should fit snugly against the glass shelf of the refrigerator. The relief structure acts as suction cups or simply increases the friction area, preventing the mat from sliding when the door is opened.
⚠️ Attention! If you place the silicone mat with the smooth side down, it will glide on the glass. This can lead to heavy food falling and damage to the glass shelf or refrigerator door.
You should also pay attention to the sides. If your rug has raised edges, they should face up. This creates a pallet effect. In some models, the sides may be barely noticeable, then you should focus on the manufacturer's logo, which is usually applied to the front side.
Textile and fleecy surfaces: styling features
Textile rugs require more delicate handling. Unlike silicone, the fabric has a clearly defined front and back sides. An error in installation here is fraught not only with discomfort, but also with rapid wear of the material.
The front side of the fleecy rug is soft, fluffy pile. This is where the products are laid out. The pile creates an air layer that minimizes the contact of vegetables with cold glass, preventing freezing and rotting of the lower part of the fruit. The reverse side is usually a dense, rigid base.
The rigid base is designed to be in contact with the shelf. It often has rubberized dots or a rough structure for adhesion. If you put such a rug with the pile down, it will quickly lose its properties, the pile will crumple and stop allowing air to pass through, which will lead to the formation of mold between the fabric and the glass.
- 🥦 For vegetables - the fleecy side is always on top for air circulation.
- 🧼 For meat, it is better to use smooth silicone mats, since the fabric absorbs juices.
- 🧊 For freezing, textiles are not suitable, use only food-grade silicone.
Some manufacturers use double-sided textile mats with different pile lengths. In this case, the longer, softer pile is for fruit, while the shorter, harder pile is for heavy groceries. Always check the markings on the packaging when purchasing.
The effect of the mat on the No Frost system and air circulation
Many users do not know that the wrong mat can disrupt operation the entire refrigerator compartment. In refrigerators with a No Frost system, cold air circulates through special channels. Shelves in such models often have holes or gaps along the edges for the passage of air flow.
If you cover such a shelf with a solid rug that is not intended for this model, you will block the access of cold air to the products lying above or below. This will make thermostat work more intensely, increasing energy consumption.
This is especially critical for the freshness zone (zero chamber). Here the temperature and humidity are strictly controlled. Using a dense, impermeable mat may cause a local increase in temperature and food will spoil faster than indicated on the packaging.
| System type | Mat requirement | Risk of error |
|---|---|---|
| Static (Drip) | Dense mats are acceptable | Low, moisture accumulation is possible |
| No Frost (Ventilation) | Perforated or mesh | High, poor circulation |
| Low Frost | Thin silicone | Medium, uneven cooling |
| Fresh Zone | Specialized perforated | Critical, food spoilage |
Always check the instructions for your refrigerator model. If the documentation says that the shelves have ventilation holes, do not cover them with solid mats. It is better to use special mesh substrates.
What will happen if you close the ventilation with a mat?
The refrigerator will work in increased mode, trying to compensate for the lack of circulation. This will lead to the formation of ice on the evaporator, fan noise and possible compressor failure ahead of schedule.
Hygiene and care: how often to change mats
Even the highest quality mat loses its properties over time. The silicone may turn yellow or develop microcracks, and the fabric may lose lint. Regular replacement and cleaning is the key to the health of your family.
It is recommended to wash silicone mats once a week along with general cleaning of the refrigerator. They are easy to clean in the dishwasher (if specified by the manufacturer) or under the tap. However, it is better to change them every six months, since bacteria invisible to the eye can multiply in microcracks.
Textile rugs require more careful care. They are necessary dry after each wet cleaning. If the rug has an odor that does not go away after washing, it should be thrown away. Fabric is an ideal environment for the development of mold, the spores of which can be dangerous for allergies. data-i="128">🎨 Change in color (yellowing, staining).
Signs that it's time to replace your rug:
- 🦠 The appearance of a persistent unpleasant odor even after washing.
- 🎨 Change in color (yellowing, spots).
- 🧱 Loss of elasticity (the mat has become hard or sticky).
⚠️ Attention! Do not use abrasive powders or chlorine-containing products to clean silicone mats. They destroy the structure of the material, making it porous and susceptible to contamination.
Step-by-step instructions for proper installation
To ensure proper operation of the accessory and the safety of the products, follow a simple algorithm of actions. It will only take a couple of minutes, but it will save you nerves and food in the future.
First, remove the shelf from the refrigerator. It is more convenient to wash and lay the rug on a horizontal surface. Wipe the glass shelf thoroughly, removing all crumbs and food debris. Then straighten the rug and determine its sides, guided by the characteristics described above (smooth / textured, pile / base).
Gently spread the rug on the shelf, smoothing it from the center to the edges to avoid the formation of air bubbles. Make sure that the mat does not block the ventilation holes (if any) and does not protrude beyond the edges of the shelf so as not to interfere with the closing of the door.
☑️ Proper placement of the mat
After installation, return the shelf to its place and let Refrigerator for 15-20 minutes to restore temperature before loading food. This is especially important for models with electronic control.
Frequent errors during operation
Even knowing the theory, users often make practical mistakes. One of the most common is the use of rugs for other purposes. For example, trying to lay a mat on a freezer if it is not intended for low temperatures.
Ordinary silicone at temperatures below -15°C can crack and crumble. There are special heat-resistant mats for freezers. It is also a mistake to stack rugs. Some try to lay one rug on top of another for “softness,” which completely blocks heat transfer.
Another mistake is ignoring damage. A torn edge of a silicone mat is where dirt accumulates. If the mat is damaged, it is better to replace it than to try to seal it or use it further.
In conclusion, it is worth noting that the correct choice and installation of the mat is a small thing that affects the overall comfort of using the refrigerator. Cleanliness, order and safety of food are worth it.
Is it possible to use ordinary kitchen silicone baking mats in the refrigerator?
Technically, it is possible if they are food-grade and suitable in size. However, baking mats are often too dense and can block ventilation. It is better to use specialized thin substrates.
How to remove the smell from a new rubber mat?
A new smell can be eliminated by washing the mat with a solution of water and vinegar (1:1) or leaving it to ventilate in the fresh air (not in the sun) for a day.
Are silicone mats harmful to products?
High-quality food-grade silicone is inert and safe. Cheap analogues made from technical rubber can pose a danger; when heated or in contact with fat, they can release harmful substances. Buy only certified products.
Do you need to remove the mats when defrosting the refrigerator?
Yes, when defrosting, it is better to remove the mats in order to thoroughly wash the shelf under them and allow both surfaces to dry. This will prevent the formation of mold.
