An unpleasant smell in the refrigerator is a problem that every second home cook faces. Even with regular cleaning, the aromas of spoiled food, fish or spices can be absorbed into the plastic, rubber seals and chamber walls. But simply wiping the shelves with a damp cloth is not enough: to eliminate the smell foreveryou need to know deep cleaning technology and use the right products.
In this article - a step-by-step algorithm taking into account the type of refrigerator (No Frost, drip, static), a list of safe detergents and life hacks for preventing odors. We'll look at why regular soda sometimes doesn't help, how to clean the drainage hole (the main source of the rotten smell) and what to do if it stinks even after general cleaning. Let us separately dwell on mistakesthat only aggravate the problem - for example, the use of bleach or improper drying.
Why odor appears: 5 main reasons
Before picking up a sponge, it is important to understand source an unpleasant odor. The most common culprits are:
- 🍳 Spoiled food - even a small piece of fish or cheese lost behind a drawer can provoke a rotten smell for weeks.
- 🧽 A dirty drainage hole - it accumulates fat, food particles and mold. If the water does not drain into the pan, rotting begins.
- 🧼 Mold on the sealing rubber - a dark and damp place is ideal for the growth of fungus. Black dots on the rubber are a sure sign.
- ❄️ Improper defrosting —if the ice thaws naturally, and not with the help of a hairdryer or warm water, the remaining moisture causes mustiness.
- 🔌 Malfunction of the ventilation system —in models No Frost the smell may appear due to a clogged air duct or a broken fan.
🔍 How to find the source? Smell each shelf, drawer and seal separately. If the smell intensifies when you open the door, there is a problem with the rubber or ventilation. If it comes from the inside even when the refrigerator is empty, the drainage hole or the back wall is to blame.
Preparation for cleaning: what needs to be done before washing
You can’t just take and wash the refrigerator - improper preparation negates all efforts. Follow the checklist:
Unplug the refrigerator (required!)
Take out all the products and check them for freshness
Remove all shelves, drawers and racks
Prepare warm water and detergent
Place a tray to collect melt water (if defrosting)-->
⚠️ Attention: If your refrigerator No Frost, you do not need to defrost it manually - just turn off the power for 1-2 hours so that the ice melts on its own. In models with drip system (for example, Atlant or Indesit) defrosting takes 3-6 hours. Do not try to speed up the process with a knife or fork - this will damage the evaporator!
💡 Tip: Before cleaning, take a photo of the location of the shelves and drawers on your phone. This will help you quickly put the refrigerator back together without getting tangled in the fasteners. This is especially true for models with a non-standard layout (for example, Samsung Family Hub or LG InstaView).
How to wash a refrigerator: safe and dangerous products
Not all detergents are equally useful. For example, bleach and aggressive bleaches destroy plastic, and flavored gels leave a sticky film, which then absorbs odors even more strongly. Here's what you can and can't use:

|---|---|---|---|
| Baking soda | ✅ Yes | 2 tbsp per 1 liter of warm water | May leave a white residue on black surfaces |
| Vinegar (9%) | ✅ Yes | 1:1 with water, wipe, then rinse | Pungent odor, requires ventilation |
| Citric acid | ✅ Yes | 1 sachet per 0.5 liters of water | Not suitable for aluminum parts |
| Laundry soap | ⚠️ Conditional | Only natural, without fragrance | Does not wash off well, a film may remain |
| Specialized sprays (for example, Topperr 3101) | ✅ Yes | Follow the instructions on the package | Expensive, not always available in stores |
🚫 What cannot be used:
- 🧴 Dishwashing detergents (Fairy, AOS>) - they foam and are difficult to wash off.
- 🧽 Abrasive powders - scratch the plastic, bacteria accumulate in microcracks later.
- 🧪 Ammonia - its smell is absorbed into the seal and lasts for months.
Step-by-step instructions: how to clean a refrigerator from odor

Common mistakes: what increases the smell instead of removing it
Many housewives themselves provoke the appearance of a persistent odor by making these mistakes:
- 🧼 Use of scented napkins. They only mask the smell, but do not remove its cause. In addition, fragrances mix with food aromas, creating a “bouquet”.
- 🔥 Hair drying. Hot air deforms plastic and rubber seals. airing.
- ❄️ Incomplete defrosting. If there is ice left in the corners, it will melt and give off a rotten smell. In models No Frost ice can accumulate in hidden channels - they need to be cleaned once a year.
- 🧴 Storing detergents inside. Many leave a bottle with Domestos or White "just in case." Chlorine is absorbed into the plastic and then poisons the food.
- 🍎 Ignore the fruit drawers. Juice accumulates in them, which begins to ferment. You need to wash the drawers as thoroughly as the shelves!
