How to wash the refrigerator so that it does not smell: a complete guide 2026

An unpleasant smell in the refrigerator is a problem that every second home cook faces. Even with regular cleaning, odors from spoiled food, plastic or mold can linger in seals, shelves and walls. But simply wiping the internal surfaces with a damp cloth is not enough: you need the right cleaning products and technology.

In this article we will examine odor elimination - from improvised means (soda, vinegar, lemon) to professional chemicals ( 10 proven ways odor elimination - from improvised means (soda, vinegar, lemon) to professional chemicals (Top House, Sano Fridge Cleaner). You will learn how neutralize the smell of fish, onions or rotten eggs in 1 hourwithout damaging the coating of the refrigerator, as well as how to prevent its occurrence in the future. Let us separately dwell on the nuances for models with the system No Frost and refrigerators with ion filters.

Why does the smell appear in the refrigerator?

The main sources of unpleasant odors are:

• 🍳 Spoiled food (especially fish, meat, dairy products). Even a small piece lost on the back shelf can cause a persistent odor.
• 🧼 Improper cleaning. The use of aggressive detergents (for example, bleach) destroys the protective coating of the plastic, and it begins to absorb odors.
• 🍄 Mold and bacteria. Moisture accumulating in the door seal or under vegetable drawers creates an ideal environment for their proliferation.
• 🔌 Faults. In models with No Frost odor may appear due to a clogged drain hole or a broken fan.

Interesting fact: according to a study National Sanitation Foundation (2023), in 36% of refrigerators, dangerous substances are found at the bottom of vegetable drawers bacteria Salmonella i Listeriathat not only spoil the smell, but also threaten health. Therefore, regular disinfection is not a luxury, but a necessity.

Preparing the refrigerator for cleaning: 5 mandatory steps

Before you start cleaning, the refrigerator must be properly prepared. This will speed up the process and make it safe:

1. Unplug it. Even if you have a model with No Frost, it is better to unplug the plug from the socket - this will prevent a short circuit if moisture gets in.
2. Take out all the products. Check expiration dates and throw out expired ones. Temporarily place foods that spoil quickly (meat, fish, milk) in a cooler bag or a bowl of ice.
3. Remove all removable elements: shelves, drawers, racks, egg tray. They need to be washed separately.
4. Pull out the refrigerator (if possible) - this makes it more convenient to wash the back wall and clean the drainage hole.
5. Prepare tools: soft sponges, a toothbrush for hard-to-reach places, microfiber napkins, rubber gloves.

⚠️ Attention: If your refrigerator has a system Air Flow or Multi Air Flow (for example, in models Samsung RB37A52 or LG GC-B247SLBV), do not direct the water stream at the ventilation openings. Moisture ingress can cause corrosion or damage to the fan.

Top 5 folk remedies for cleaning the refrigerator

3. Back wall —in models with a drip system, sometimes there plaque forms.

4. Ventilation grilles (in No Frost) - they need to be cleaned with a toothbrush.

Professional chemistry: what to choose?

If traditional methods do not help, specialized tools will come to the rescue. They come in three types:

• 🧴 Gels and sprays —easy to apply, often have antibacterial additives (Sano Fridge Cleaner, Topperr 3101).
• 🧽 Foams —penetrate well into microcracks in plastic (Bagi Shumanit for refrigerators).
• 💊 Tablets and odor absorbers - installed inside after cleaning (Air Wick Air Purifier, Filtrete).

When choosing, pay attention to:

• 🔍 Composition: avoid products with chlorine - it corrodes plastic and spoils seals.
• 📌 Purpose: some products only mask the smell and do not remove it (air fresheners will not be suitable).
• 🛡️ Safety: for refrigerators with ion filters (for example, Panasonic NR-BN30A1) you need products marked safe for ionizers.

How to wash a refrigerator with a No Frost system?

Refrigerators with No Frost (for example, Bosch KAN92VI30R or Indesit ITF 118 W) require a special approach. They cannot be washed in the same way as conventional models, because of:

• 🔗 Hidden drainage channels —their clogging leads to an odor.
• ❄️ Automatic defrosting —aggressive agents can damage the sensors.

Step-by-step instructions:

1. Turn off the refrigerator and wait for complete defrosting (2-3 hours).

Cleaning the rubber seal: why is this important?

The sealing gum (or magnetic. seal) is the main place where dirt and bacteria accumulate. According to German Appliance Testing Institute, in 78% of cases, the unpleasant odor comes from here, the rubber absorbs fat, food particles and moisture, creating ideal conditions for mold.

How to clean the seal:

1. Prepare a solution: 1 tbsp. ammonia per 1 liter of water (or use a specialized product, for example Mellerud for seals).
2. Dental use a brush or cotton swab to go through all the folds of the elastic band.
3. To disinfect, wipe with hydrogen peroxide (3%).
4. Apply a thin layer of silicone grease (for example, WD-40 Specialist) - this will prevent cracking and extend service life seal.

💡 Useful advice: If the rubber is deformed or has lost elasticity, it needs to be replaced. For models Atlant and Samsung seals are sold in service centers (articles can be found in the instructions). The average cost is from 800 to 2500 rubles.
