The question of how to properly place a mat in the refrigerator often arises among those who strive for perfect order in the kitchen or are faced with the problem of dirty glass shelves. Many users don’t even think that the position of this simple accessory determines not only the cleanliness, but also the safety of food, as well as the efficiency of the cooling system. Incorrect installation can lead to spilled liquid flowing under the glass, and dirt will accumulate in hard-to-reach places.
In this article we will analyze in detail the features of different types of rugs, explain the difference between the front and back sides, and also give practical advice on care. You will understand why manufacturers sometimes indicate the direction of installation and how this affects the air circulation inside the chamber. The correct approach to this issue will allow you to avoid unnecessary hassle with washing the refrigerator in the future.
In modern models of refrigerators, such as Bosch, Liebherr or LG, the shelves are often made of tempered glass, which is easy to clean, but tends to slide.
Exactly to prevent slipping of cans and bottles, as well as to protect the surface from scratches, special mats are used.
However, not everyone knows that many of them have a specific texture on both sides, each of which performs its own function.
Why do you need a mat in the refrigerator at all
The main function of the mat is to create a barrier between products and the shelf of the refrigerator.
This is especially true for glass surfaces, which can crack due to a sudden temperature change or mechanical shock with a heavy object.
In addition, the mat prevents the spreading of spilled liquids, collecting them in its structure and preventing them from getting into the gaps between the shelf and the body.
An important aspect is hygienic safety.
Many modern models are made of antibacterial materials that suppress the growth of mold and bacteria.
This is especially important for the storage area of vegetables and fruits, where humidity is high and the risk of food spoilage is high.
- 🛡️ Protecting glass shelves from scratches and chips when moving heavy pots.
- 💧 Collection of spilled liquids, preventing them from entering the ventilation system.
- 🌬️ Providing additional air circulation around products thanks to the relief surface.
Using a mat also simplifies the cleaning process.
Instead of washing the entire shelf, removing heavy glass and drying them, you just need to remove and rinse the mat under the tap.
This saves time and effort, making keeping the refrigerator clean is less labor-intensive.
Types of mats and their features
Before deciding which side to lay the mat on, you need to determine its type.
There are several main varieties on the market, each of which has its own design features.
The most common are silicone and polyethylene models, which can be transparent or colored.
One of the popular options are mats with a relief surface.
They often have a “honeycomb” or “wave” structure, which allows products not to fit tightly to the surface.
This creates an air gap, improving cooling and preventing food from freezing to the bottom.
⚠️ Attention: Some cheap PVC mats can become brittle at low temperatures and emit an unpleasant odor. Make sure that the material is marked as frost-resistant and food grade.
There are also models with suction cups or anti-slip coating.
They are designed for installation on smooth glass shelves to prevent the mat from moving along with the products.
In such models there is one the side is always smooth and sticky, and the other is textured.
How to determine the front and back sides
Determining the correct side of the mat is key to its effective operation.
In most cases, manufacturers make one side smooth and the other rough or ribbed.
The smooth side is usually designed to contact the refrigerator shelf to ensure a snug fit.
If the mat has a mesh structure, then large cells are often directed upward.
This allows you to collect spilled liquid in “pockets”, preventing it from spreading over the entire surface.
However, there are models where the mesh, on the contrary, should lie on the glass to create a gap.
To determine the side, pay attention to the following signs:
- 🔍 The presence of a manufacturer's logo or inscriptions (they should be read from above).
- 🖐️ Tactile sensations: the rough side is more likely to come into contact with products.
- 💧 Capillary effect: if you pour a little water, it should flow into the recesses, and not spread.
Some instructions for refrigerators Samsung or Indesit may indicate that perforated mats are laid with holes down.
This is necessary so that cold air can circulate through the holes, ensuring uniform cooling of the bottom of the food.
Ignoring this rule can lead to local hypothermia or, conversely, damage to the products in the center of the shelf.
Laying rules for different types of shelves
The method of laying the mat directly depends on the type of shelf on which it is placed.
Glass, plastic and metal are used in refrigerators gratings, each of which requires a special approach.
The wrong choice of side can lead to damage to the shelf or the mat itself.
For glass shelves the best option is to lay the smooth side down.
This prevents the formation of air bubbles and ensures stability.
If the mat has suction cups, they should also face the glass.
On metal grates (often found in freezers or freshness areas) mats are used less frequently.
If you decide to cover the grate, choose models with large cells so as not to block the access of cold air from below.
Here the mat is placed with the rough side up to fix the products.
| Type shelves | Recommended side | Purpose of installation |
|---|---|---|
| Tempered glass | Smooth down | Protection against slipping and scratches |
| Plastic (door) | Texture up | Fixation of cans and bottles |
| Metal grid | Perforation up | Air circulation |
| Freshness zone | According to instructions | Humidity preservation |
It is important to consider that the mats should not block the ventilation holes.
If your refrigerator model has air circulation holes located at the back of the shelf, make sure that the mat does not completely cover them.
If necessary, the mat can be trimmed with scissors if the material allows this.
The influence of the mat on the operation of the No Frost system
Owners of refrigerators with the system No Frost often wonder whether the mat will interfere with the operation of ventilation.
The No Frost system is based on the constant circulation of cold air, which is pumped by a fan and distributed throughout the chamber.
Any obstacle in the path of air flow can reduce cooling efficiency.
Thin silicone mats have virtually no effect on the operation of the system.
However, thick fleecy or foam mats can become a barrier to cold air, especially if they are placed on the bottom shelf above the drawer vegetables.
In such areas, air is often supplied from below or from behind, and dense material can disrupt this process.
⚠️ Attention: Do not use mats that completely cover the perforated bottom of the refrigerator compartment. This can lead to overheating of the compressor or the formation of ice.
If you notice that the food on the shelf with the mat has begun to freeze or, conversely, spoil faster, try removing the mat.
This will help diagnose a problem with cold distribution.
In some cases, it is enough to simply turn the mat over to the other side to change the nature of air circulation under it.
The myth of thermal insulation
There is an opinion that the mat works as a heat insulator and protects food from the cold. In fact, silicone conducts temperature quite well, and there should not be a significant difference in the temperature of food on the mat and without it (if the refrigerator is working). The main function is hygiene and protection.
Care and cleaning of mats
Regular cleaning of mats is necessary to maintain hygiene in the refrigerator.
Over time, food debris, juice and bacteria can accumulate in the surface texture.
Wash mats should be warmed with warm water and a mild detergent.
It is not recommended to use abrasive sponges or aggressive chemicals.
They can damage the structure of the material, make it rough or change color.
For disinfection, you can use a solution of baking soda or a weak vinegar solution.
The cleaning process is as follows:
- 🚿 Rinse the mat under running warm water, removing large dirt.
- 🧼 Lather the surface with a soft sponge with a neutral agent.
- 🌬️ Rinse thoroughly and allow to dry naturally before returning to the refrigerator.
It is important to dry the mat completely before putting it back.
Moisture between the mat and the shelf can be an ideal breeding ground for mold.
If the mat has a persistent odor, you can soak it in a citric acid solution for 15-20 minutes.

Common mistakes when using
Despite the simplicity of the accessory, users often make mistakes that reduce its usefulness to zero.
One of the most common mistakes is using mats of the wrong size.
If the mat is too large, its edges can bend, creating inconvenience and collecting dirt.
Another mistake is using mats in the freezer without checking their frost resistance.
Ordinary plastic at temperatures -18°C and below becomes brittle and can crumble into small pieces, which then get into food.
Always check the label for packaging or the product itself.
Also, you should not lay several layers of mats on top of each other.
This creates a “thermos effect” and disrupts heat transfer.
One high-quality layer is enough to perform all protective functions.
The relationship between the mat and the service life of the refrigerator
Although the mat seems like a small thing, its correct use indirectly affects the durability of the equipment.
By protecting the glass from scratches, you prevent the formation of microcracks, which over time can lead to destruction shelves.
Broken glass falling on plastic parts or a fan can cause serious damage.
In addition, preventing aggressive liquids (lemon juice, vinegar, wine) from getting directly onto rubber seals or plastic housing elements prolongs their life.
Mat takes the blow, preserving the integrity of the internal elements of the refrigerator.
Regular replacement of worn-out mats is part of the proper care of household appliances.
It should be noted that refrigerator manufacturers do not always equip equipment with mats.
Often this is an option that the user purchases separately.
When choosing, pay attention to the quality of the material and the absence of a sharp chemical smell.
Can silicone be washed Is the mat dishwasher safe?
In most cases, silicone mats can be washed in the dishwasher if there is a corresponding symbol on the packaging. However, high temperatures and harsh detergents can make silicone sticky or change color over time. It is recommended to wash them by hand with warm water and a mild detergent.
Why does the mat slide on the glass?
This can happen if you put the mat on the wrong side (smooth side up instead of rough) or if the surface of the glass and mat are too wet. Also, cheap mats made from low-quality PVC can slide regardless of the side of installation. In this case, it is better to replace the accessory with a model with suction cups or an anti-slip coating.
Are PVC mats harmful to food?
High-quality food-grade PVC is safe. However, cheap products may contain phthalates and other harmful substances, which are especially actively released when in contact with fatty foods. Always buy rugs labeled "Food Safe" or "Food Grade Plastic" and avoid products with a strong, unpleasant odor.
How to remove the smell from a new rug?
A new rug can be washed with a solution of warm water and baking soda, then rinsed with water and lemon juice. After this, it needs to be dried well in the fresh air (not in direct sun) for 24 hours. If the smell remains strong and pungent, it is better to return the product to the store, as this is a sign of poor quality material.
Do you need to remove the mat when defrosting the refrigerator?
Yes, when completely defrosting the refrigerator, the mats must be removed. Water may accumulate under them, which will freeze and damage the structure of the rug or the glass of the shelf. In addition, this is the only opportunity to properly wash the shelf under the rug.
