• 🧴 Sour liquids - spilled milk, juice or sauce absorbed into the plastic.
• 🔥 Combustion of plastic or insulation - a characteristic "chemical" smell indicates a malfunction.
• 🦠 Bacteria in the cooling system - especially relevant for models with drip defrosting.

If the refrigerator has been turned off for a long time, a smell may appear due to stagnant air in a confined space - this is a normal phenomenon that can be eliminated ventilation.

How to get rid of the smell in the drainage system?

If the smell remains after cleaning the refrigerator, the problem most likely lies in the drainage system. This is where most organic residues accumulate, which decompose and emit a stench. Cleaning the drainage consists of several stages:

1. Mechanical cleaning:

• 🧹 Use a special brush or wire with a bent loop at the end.
• 💦 Wash the hole with warm water and soap, using a syringe or syringe.

2. Disinfection:

• 🧪 Pour 50 ml of chlorhexidine solution (0.05%) or hydrogen peroxide (3%) into the drainage hole.
• 🍋 After 15 minutes, rinse the system with clean water.

In models with drip defrosting system (for example, Atlant, Biryusa), the drainage hole is often clogged with ice. In this case, before cleaning, you need to completely defrost the refrigerator (at least 12 hours) and remove all ice build-up.

What to do if the drainage hole is clogged with ice?

If after defrosting the water does not go into the drainage, try carefully clearing the hole with a wooden stick (for example, a sushi stick). Do not use metal objects as they may damage the plastic tube. After cleaning, rinse the system with warm water with the addition of citric acid (1 teaspoon per glass of water).

How to wash plastic containers and shelves?

Removable refrigerator elements are a breeding ground for bacteria. They need to be cleaned separately from the main body, using more aggressive methods. Here's what really works:

• 🧂 Salt + soda - make a paste, apply for 20 minutes, then rinse. Excellent for removing yellowness and grease.
• 🍎 Apple cider vinegar —soak the shelves in a solution (1:1 with water) for 1 hour. Kills mold.
• 🧼 Laundry soap (72%) - rub the drawers with it, leave for 30 minutes, rinse with hot water.
• ☀️ Sunbathing - after washing, leave the plastic in the sun 2-3 hours. Ultraviolet destroys bacteria.

For persistent stains, you can use melamine sponge, but with caution - it can leave scratches on glossy surfaces. Alternative: a paste of soda and hydrogen peroxide (mix to the consistency of toothpaste, apply for 10 minutes).

If the containers have a strong plastic smell (often the case with new refrigerators from Chinese brands), soaking in a salt solution (2 tablespoons per 1 liter of water) for 12 will help hours. After this, the smell should disappear.

Prevention: how to prevent the appearance of odor?

Regular maintenance of the refrigerator will save you from the need to deal with old odors. Here are proven methods of prevention:

• 📅 Weekly audit —check products for freshness, throw away spoiled ones.
• 🧊 Odor absorbers —use a soda solution (2 tablespoons of soda per 1 liter of water in an open container) or special carbon filters.
• 🧻 Paper towels - place them on the bottom shelf to absorb excess moisture.
• 🌿 Natural flavors - lemon slices, rosemary sprigs or coffee beans neutralize extraneous odors.

For refrigerators with No Frost system it is especially important to monitor the condition of the sealing gum. Over time, it loses its elasticity, and bacteria penetrate into microcracks. Wipe the gum with a vinegar solution (1:1 with water) once a month - this will extend its service life.

Another secret: do not store unpackaged food in the refrigerator. Even covered with cling film does not provide 100% protection. The best option is sealed containers made of glass or food-grade plastic. They prevent the spread of odors between products.

FAQ: answers to frequently asked questions

Can bleach be used to clean a refrigerator?

Bleach is effective against mold, but it can only be used in a highly diluted form (1 tbsp. spoon per 1 liter of water). Never use undiluted bleach on plastic or rubber seals; it will destroy them. After treatment, thoroughly rinse all surfaces with clean water and ventilate the refrigerator for at least 2 hours.

Why does the smell return after cleaning after a few days?

This means that the source of the odor has not been completely eliminated. Most often, the problem lies in the drainage system, behind the rubber seal or under the plastic panels (in models with a hidden cooling system). Try repeating the cleansing focusing on these areas. If the smell remains, it may have penetrated the foam insulation of the housing. In this case, only professional treatment with an ozonizer will help.

How to clean a refrigerator with a No Frost system without damaging it?

For No Frost you cannot use abrasive agents, hard brushes or large amounts of water. The best option is special sprays for refrigerators (for example Dr. Beckmann) or a solution of vinegar (1:1 with water). Apply the product to a soft cloth, not to the surface. Avoid getting liquid on the ventilation openings. After cleaning, wipe all surfaces dry.

How to clean the inside of the refrigerator from yellowness?

Yellowness on plastic appears due to oxidation or exposure to fat. Effective means:

• Paste of soda and hydrogen peroxide (1:1) - apply for 15 minutes, then rinse.
• Toothpaste with a whitening effect - rub in with a soft sponge.
• Citric acid (2 tablespoons per 1 liter water) - soak the removable elements for 1 hour.

For white plastic, you can use a melamine sponge, but without pressure, so as not to damage the surface.

Is it worth using fragrances for the refrigerator?

Flavors mask the smell, but do not eliminate its cause. In addition, many synthetic flavors can react with foods, giving them an off-flavor. It is better to use natural odor absorbers: soda solution, activated carbon or coffee beans. If you want aroma, add a slice of lemon or a sprig of mint, but not longer than 2-3 days.
