The refrigerator is the heart of any kitchen, and maintaining its internal hygiene is a task of paramount importance for every home cook. The question of how to lay mats in a refrigerator often arises not just from aesthetic considerations, but from the practical need to protect glass shelves from scratches and make it easier to clean up spilled liquids.
A properly selected and laid mat creates an additional buffer layer that prevents direct damage to the tempered glass when placing heavy pots or jars. In addition, this solution allows you to avoid spilled milk or juice spreading over the entire surface of the shelf, which greatly simplifies subsequent disinfection.
In this article, we will analyze in detail the surface preparation algorithm, types of materials and the nuances of their installation, so that your refrigerator serve for a long time, and the products remain fresh. We will also touch on common mistakes that can lead to the appearance of mold under the rug.
Choosing the appropriate material to protect the shelves
Before you begin the question of how exactly to lay the covering, you need to decide on the material itself. The market offers many options, but not all of them are suitable for low temperatures and contact with food.
The most popular solution is silicone mats. They are flexible, easy to clean and do not absorb odors. It is important to choose products made from food-grade silicone, which does not release toxins when cooled. Such mats often have a textured surface, which improves air circulation.
The second option is specialized plastic or acrylic trays. They are more rigid and are often sold as accessories for specific models Samsung or LG. Their advantage is that they do not deform over time and have clear sides.
The third, more budget option is mats made of polyethylene foam or EVA material. They hold their shape well and have thermal insulation properties, but require a more careful choice, since cheap analogues can crumble in the cold.
- 🧪 Silicone —ideal for flexibility and dishwasher washing, but can slide on glass.
- 🛡️ Acrylic/Plastic —provides tough protection against impacts, but takes up more space in height.
- 📦 EVA material —light and cheap, but requires testing for frost resistance.
⚠️ Attention: Never use regular yoga mats or building insulation in the refrigerator that is not labeled "food grade" contact". At low temperatures, they may begin to release harmful substances or disintegrate into microparticles.
Preparation of the inner chamber before laying
The process of laying mats begins long before the very moment of laying. It is critical to properly prepare the glass shelf surface. If you cover dirty or damp glass, you will create an ideal environment for the growth of bacteria and mold.
First you need to completely empty the shelf of products. Remove the glass panel carefully, holding it on both sides, and remove it from the refrigerator. Wash the glass with warm water and a mild detergent. Do not use abrasive sponges, which can leave micro-scratches.
After washing, the surface must be completely dry. Wipe the glass with a dry microfiber cloth and let it sit at room temperature for 10-15 minutes. This is necessary so that condensation, which inevitably forms when cold glass comes into contact with warm air, evaporates.
Pay special attention to the edges of the shelf and the place where it is inserted into the guides. Dust and crumbs often accumulate there. To clean hard-to-reach places, you can use a cotton swabmoistened in an alcohol solution.

Styling technology: how to avoid bubbles and shifts
The most common question is how to lay the rug so that it does not move every time the door is opened. The main mistake is trying to straighten the material directly inside the refrigerator compartment. This leads to the formation of air pockets and unevenness.
The correct algorithm of actions looks different. Place the mat on a flat table at room temperature. If the material is rolled, allow it to straighten under its own weight or lightly press it with a weight along the edges for 10 minutes. Cold material is less elastic and may break.
Carefully place the straightened mat on a dry glass shelf. Start gluing (if using a self-adhesive option) or laying from one of the far corners, gradually smoothing the surface with your hand or a soft spatula from the center to the edges. This will squeeze out excess air.
If you are using a non-self-adhesive silicone sheet, make sure that it fits snugly over the entire area of the glass. The voids between the glass and the mat can cause the glass shelf to burst under the weight of heavy food due to uneven pressure distribution.
Insert the shelf with the already covered mat back into the refrigerator. Do this smoothly, without jerking, making sure that the edges of the mat do not touch the guides and do not curl up.
What to do if the mat moves out after installation?
If you notice that the mat has moved, do not try to straighten it inside the refrigerator. Take out the shelf again, let the material warm up to room temperature (cold silicone “dumbs”), straighten it on the table and repeat the installation procedure again.
The specifics of installation in different areas of the refrigerator
Different compartments of the refrigerator require an individual approach. The operating conditions in the freezer compartment are much harsher than in the main compartment. The temperature there drops to -18°C and below, which changes the properties of the materials.
In the freezer it is better to use hard plastic trays or special frost-resistant silicones. Thin film mats may crack. When placing it in the freezer, it is important to leave micro-gaps at the walls for the circulation of cold air, if the design of the box allows this.
In the freshness zone (zero chamber) the humidity is often increased. Here the mats must have antibacterial properties. Glass shelves in this area often have perforations or special grooves - make sure that the mat does not block the ventilation holes.
Mags are rarely laid on refrigerator doors, since bottles and cans of different heights are stored there. However, for the lower shelves of the door, you can use narrow silicone strips, which will prevent bottles from rattling when the door slams.
| Refrigerator area | Recommended material | Temperature range | Features styling |
|---|---|---|---|
| Main chamber | Silicone, EVA | +2...+5°C | Tight fit, scratch protection |
| Freezer | Frost-resistant plastic | -18...-24°C | Important impact resistance and lack of deformation |
| Fresh zone | Antibacterial silicone | 0...+2°C | Do not block the ventilation holes |
| Door | Thin tape/mat | +3...+7°C | Fixation of bottles, protection from breakage |
⚠️ Attention: In models with the system No Frost it is impossible to cover the back wall or air duct openings with mats. This will disrupt air circulation and lead to the formation of ice or compressor failure.
Caring for rugs and preventing mold
Even if you know how to lay rugs correctly, without regular care they will become a breeding ground for bacteria. Mold loves damp, dark spaces, and the gap between the rug and the glass is an ideal place for it to grow.
It is recommended to remove rugs and wash them at least once a month. Silicone products can be washed in warm water with soda or vinegar. These natural antiseptics perfectly remove odors and kill microorganisms.
Plastic pallets are less demanding, but they also need to be disinfected. Use a soft sponge to avoid scratching the surface; dirt accumulates faster in scratches. After washing, be sure to dry the mat before re-covering the shelf.
If you notice black spots of mold on the silicone that do not come off, it is better to replace the mat. Mold penetrates deeply into the structure of porous materials, and it is almost impossible to remove it completely.
Common mistakes when installing protective coatings
Many users make mistakes that negate all the benefits of using mats. One of the most common is the use of too thick a material.
If the mat is too thick, it reduces the usable volume of the refrigerator and may prevent the door from closing tightly. This leads to excessive energy consumption and freezing of the seal. The thickness of the mat should not exceed 2-3 mm.
Another mistake is the use of several layers. Some people try to lay one rug on top of another for "better protection." This creates an unstable surface, food begins to wobble, and condensation accumulates between layers.
Ignoring the refrigerator manufacturer's instructions is also dangerous. In some models Bosch or Whirlpool the design of the shelves implies specific ventilation from below. A completely sealed mat can disrupt the temperature regime in the lower part of the chamber.
Is it possible to lay ordinary food mats (silicone) in the refrigerator?
Yes, you can, but only if They are made of food grade silicone and are odorless. Conventional technical mats may contain harmful impurities.
How often do you need to change mats in the refrigerator?
The service life depends on the material. Silicone mats last 2-3 years, plastic pallets - up to 5 years. Change them if cracks, persistent odor or mold appear.
Why does water form under the mat?
This is condensation that occurs due to temperature differences or loose fit of the material to the glass. It is necessary to remove the shelf, wipe the glass and mat dry, and reinstall them.
Does the mat affect the operation of the No Frost system?
If the mat covers the ventilation holes on the back wall or on the sides of the chamber, air circulation is disrupted. This can lead to improper operation of the defrost system.
