Folk remedies - a safe and budget-friendly alternative to aggressive chemicals, especially if there are allergy sufferers or small children in the house.
In this article you will find 10 proven ways to eliminate odor using available ingredients, as well as tips for prevention. We will look at which products work best against mustiness, fish or mold aroma, and how to use them correctly so as not to damage the seals and camera coating. All methods are suitable for refrigerators No Frost, drip systems and models with a freshness zone.
Why the refrigerator starts to smell bad: 5 main reasons
Before dealing with the effect, it is important to understand the cause. The most common culprits are:
- 🍎 Spoiled products —even one rotting fruit or a package of sour milk can “flavor” the entire chamber.
- 🦠 Bacteria and mold —accumulate in seals, on shelves and in the drainage hole, if general cleaning is not carried out cleaning.
- 🧊 Clogged drainage —water does not drain, stagnates and begins to rot (especially true for models with a drip system).
- 🧀 Strong-smelling foods —fish, cheeses, spices without sealed packaging “share” the aroma with neighboring ones products.
- 🔌 Power outage —if the refrigerator has been left turned off for a long time, a musty smell may appear inside.
In 80% of cases, the problem is solved deep cleaning by proper organization of storage. But if the smell is persistent, additional measures will be needed.
⚠️ Attention: If the unpleasant odor is accompanied by constant fan noise (in models No Frost) or smudges on the back wall, this may indicate a malfunction. In this case, first fix the technical problem, and then deal with the smell.
Preparing the refrigerator to eliminate the smell: step-by-step instructions
Before using folk remedies, you need to properly prepare the refrigerator:
- Disconnect from the network and remove all the food. Check expiration dates - throw away anything suspicious.
- Remove shelves, drawers and grilles. They need to be washed separately in warm water with soda or vinegar.
- Wipe the walls with a soft sponge soaked in a soapy solution (dishwashing detergent is suitable). Avoid abrasive powders - they scratch the coating.
- Clean the rubber seals with a toothbrush dipped in vinegar or lemon juice. This is where the most dirt and bacteria accumulate.
- Rinse the drainage hole (usually located on the back wall). Use a cotton swab or a special brush.
After washing, leave the refrigerator open for 1-2 hours to ventilate it. Only after this can you begin to neutralize the smell.

What not to remove the smell in the refrigerator: common mistakes
Some “folk” tips may not only not help, but also aggravate the problem. Here is what you can’t do:
- 🚫 Use perfumes or air fresheners - they only mask the smell, but do not eliminate its cause. products have a chemical taste.
- 🚫 Place open containers with liquids (for example, vinegar or pure ammonia) - vapors can damage rubber seals.
- 🚫 Wash the refrigerator with hot water — due to temperature changes, the plastic may be deformed, and the seals will lose elasticity.
- 🚫 Leave wet towels inside to “absorb” the smell - this creates ideal conditions for the growth of bacteria.
You should also not use aromatic candles or smoking sticks —soot and soot will settle on the walls, and then it will be difficult to wash them.
Prevention of unpleasant odors: 7 rules for storing food
To prevent the smell from returning, follow these recommendations:
- Store foods in airtight containers. This is especially true for cheeses, sausages, fish and spices.
- Check expiration dates regularly. Conduct an audit once a week - throw away spoiled or suspicious products.
- Use odor absorbers. Even when the refrigerator is clean, you can put a pack of soda or a bag of charcoal on the shelf for prevention.
- Do not place hot dishes. Steam condenses on the walls, creating a favorable environment for bacteria.
- Defrost the refrigerator according to the instructions (for models without No Frost). Ice and snow accumulate odors.
- Wash containers for vegetables and fruits at least once every 2 weeks - rot often accumulates in them.
- Ventilate the refrigerator after general cleaning, before loading food back.
If your refrigerator has a function AntiBacteria or FreshZone, do not neglect its settings - they help keep food fresh longer.
How often should you wash refrigerator?
Ideal cleaning schedule:
- 📅 Weekly: wipe shelves with a damp cloth, check food for freshness.
- 📅 Once a month: general wash with soda or vinegar, cleaning seals.
- 📅 Once every 3 months: deep cleaning of the drainage hole and back wall (if available).
If there are allergy sufferers or small children in the house, wash the refrigerator more often - once every 2-3 weeks.
What to do if the smell remains after all the procedures
If no remedy helps, the problem may be deeper:
- 🔍 Mold under plastic panels — in this case you will have to disassemble the refrigerator (it is better to call a specialist).
- 🔧 Malfunction of the drainage system — The water doesn't go away, it stagnates and goes out. The tube needs to be cleaned or replaced.
- 🧪 Odor absorbed into the plastic —if the refrigerator is old, the plastic could be “saturated” with aromas. Only replacing the internal panels will help.
In such cases folk remedies are powerless - professional cleaning or repair is needed. If the refrigerator is under warranty, do not try to disassemble it yourself, so as not to lose the right to free service.
⚠️ Attention: In refrigerators with a system No Frost an unpleasant odor may appear due to Fan contamination. To get to it, remove the back panel in the freezer (with the power off!). Clean the fan carefully, without pressing, so as not to damage the blades.
FAQ: Frequently asked questions about the smell in the refrigerator
Can I use laundry soap for washing refrigerator?
Yes, but with caution. Laundry soap (72%) disinfects well, but it must be rinsed off thoroughly so that soap residue does not remain. After washing, wipe the walls with clean water and vinegar (1:1) to neutralize the alkali.
Does a UV lamp help against odor?
A UV lamp does kill bacteria and mold, but it must be used correctly: turn it on for 15-20 minutes in an empty refrigerator once a month. Do not look at a working lamp without protection - it is harmful to your eyes. Also make sure that your refrigerator model is compatible with this method (in the instructions for Samsung RB37J5240 or LG GA-B489YELZ there are warnings about the effects of UV on plastic).
How to remove the smell of new plastic in a refrigerator?
This is a typical problem for new refrigerators (especially budget ones models Indesit or Beko). To remove the “chemical” aroma:
- Wipe the walls with a solution of vinegar (1:1 with water).
- Put a bowl of ground coffee or citrus peels on the shelf for 2-3 days.
- Ventilate the refrigerator with the door open for 24 hours before the first use.
If the smell does not go away after a week, contact the service center - perhaps this is a plastic defect.
Can ammonia be used for disinfection?
Ammonia is effective against bacteria, but has a strong odor and is toxic. If you decide to use, dilute 1 tsp. ammonia in 1 liter of water, quickly wipe the walls and rinse thoroughly. Do not leave the solution for a long time —vapors can be absorbed into the plastic. After processing, ventilate the refrigerator for at least 5–6 hours.
Why does the refrigerator smell worse after defrosting?
This is due to:
- Remnants of melt water that has stagnated in the pan or drainage.
- Activation of bacteria after thawing of ice (especially if defrosting was long).
- Mold that could develop under the seals during shutdown.
After defrosting, be sure to dry all surfacesrinse the drainage and wipe sealants with vinegar.
