How to remove the smell in the refrigerator with soda: step-by-step instructions and secrets

An unpleasant smell in the refrigerator is a problem that every home cook faces. It appears suddenly: either because of a fish forgotten on a shelf, or because of spilled milk, or simply “from time to time.” But regardless of the reason, food aroma it is quickly absorbed into plastic, rubber seals and even food. Chemical air fresheners mask the problem only for a while, but baking soda (sodium bicarbonate) copes with the source of odor at the molecular level.

Soda neutralizes acidic and alkaline compounds, which are the main ones "culprits" of the stench. At the same time, it is absolutely safe for health, does not leave toxic traces and costs a penny. In this article - 5 proven methods the use of soda to eliminate odor, including express methods and deep cleaning. And also - a table of effectiveness for different types of pollution and answers to frequently asked questions.

But before you start cleaning, it is important to understand: soda does not work as a masker, but as absorbent and neutralizer. It absorbs odor molecules and destroys their structure. Therefore, the result depends on the correct concentration of the solution, exposure time and application technique. For example, for a fresh smell of fish, a 2-hour treatment is enough, but the old “aroma” of mold will require 12 hours of contact with a soda solution.

Why is soda more effective than specialized products?

There are dozens of air fresheners for refrigerators on store shelves - from gels to sprays with lavender or lavender scents citrus. But they have three key disadvantages:

  1. They mask odor, rather than eliminating its cause.
  2. They may contain allergens or irritants (for example, limonene citrus fruits aromas).
  3. They cost 10-20 times more than soda with similar effectiveness.

Soda works according to the principle chemical neutralization. It interacts with volatile organic compounds (the same molecules that cause odor) and converts them into salts - harmless and odorless substances. For example:

  • 🍋 Sour odors (expired dairy products, fruits) - soda neutralizes excess hydrogen ions.
  • 🐟 Ammonia and sulfur compounds (fish, eggs) - absorbs amines and hydrogen sulfide.
  • 🍄 Mouldy notes - destroys the mycelium on surfaces.

In addition, soda has mild abrasive properties, which allows it to be used for data-i="81">—the main “storage” of odors. Unlike vinegar, it does not corrode plastic and does not leave behind its own aroma. cleaning rubber seals - the main "storage" of odors. Unlike vinegar, it does not corrode plastic and does not leave behind its own aroma.

⚠️ Attention: If the smell in the refrigerator is accompanied by black dots on the walls or mucus, this is a sign of mold. In this case, soda treatment should be combined with antifungal agents (for example, hydrogen peroxide 3%).

Method 1: Dry soda - an express method for fresh odors

This is the most a simple and quick option that is suitable for minor odors (for example, if the refrigerator has “absorbed” the aroma of onions or garlic). You will need:

  • 📦 Baking soda - 2-3 tablespoons.
  • 🧻 Clean fabric napkin or gauze.
  • 🧲 Magnet (if you use a jar).

Step-by-step instructions:

  1. Pour baking soda into a small container (a shot glass, a jar of baby food, or even gauze folded in several layers will do).
  2. Place the container on the middle shelf of the refrigerator. If you use a jar, secure it to the door with a magnet.
  3. Close the refrigerator and do not open for 12-24 hours.
  4. After time, remove the soda and ventilate the refrigerator for 10-15 minutes.

This method works due to adsorption: odor molecules are attracted to the porous structure of the soda. The effectiveness depends on the contact area - so it is better to use wide containers (for example, a saucer) instead of tall glasses.

Make sure that the soda is fresh. (not lumpy)

Use a container with a large surface area

Do not place soda next to open foods

Ventilate the refrigerator after processing-->

Critical nuance: dry soda will not cope with old odors (over 3 days) or mold. In such cases, wet treatment is required (see methods 2-4).

Method 2: Soda solution for washing shelves and walls

If the smell is ingrained in plastic or rubber seals, you will need wet cleaning with soda solution. for:

  • 🧀 Smells of cheese, sausage, smoked meats.
  • 🥛 Sour milk or sour sauces.
  • 🦠 Light mold on the seals.

Preparing the solution:

1 liter of warm water (40-50°C)

2 tablespoons of baking soda

1 teaspoon of liquid soap (optional, for better cleaning)

Processing technique:

  1. Remove all food from the refrigerator. Rinse the shelves and drawers (if removable) separately in the sink.
  2. Apply the solution to the walls, door and sealing rubber using a sponge or sealant spray. use a toothbrush —it penetrates the pores better.
  3. Leave the solution for 15-30 minutes (for strong odors - up to 1 hour).
  4. Rinse with clean water and wipe the surfaces dry with a microfiber cloth fabric.

For rubber seals you can use soda paste:

1 tbsp. soda

1 teaspoon of water

Apply to the elastic band, rub with a brush, rinse off after 10 minutes.

⚠️ Attention: Do not use abrasive sponges or metal scrapers - they damage the coating of the refrigerator, and odors will be absorbed even more actively.

Method 3: Deep cleaning with baking soda and peroxide (for persistent odors)

If the refrigerator has not been cleaned for years or spoiled food has been stored in it (for example, rotten meat), ordinary soda may not do the job. In such cases, it will help combined solution of soda and hydrogen peroxide. Peroxide destroys organic compounds, and soda neutralizes residual odors.

Solution recipe:

  • 1 liter of hot water (60-70°C).
  • 3 tablespoons of soda.
  • 2 tablespoons hydrogen peroxide 3%.
  • 1 tablespoon of vinegar (optional, for disinfection).

How to clean:

  1. Unplug the refrigerator and remove all shelves/drawers.
  2. Apply the solution to all surfaces (including the back wall, if it is open).
  3. For plastic parts, use a soft sponge, for metal ones (for example, shelves in No Frost) - microfiber.
  4. Leave the solution for 1 hour, then rinse with clean water.
  5. Wipe the surfaces with a dry cloth and leave the refrigerator open for 2-3 hours to ventilate.

This method is especially effective for refrigerators with a system No Frostwhere odors are often concentrated in ventilation ducts. To clean them, use cotton swabsmoistened in a soda-peroxide solution.

Type of odor Recommended method Time effects Additional means
Fresh (onion, garlic) Dry soda in a container 12-24 hours Not required
Sour (milk, cheese) Soda solution (2 tbsp/liter) 30-60 minutes Vinegar for disinfection
Fish/meat Soda + hydrogen peroxide 1 hour Lemon essential oil
Mold Soda + peroxide + vinegar 2 hours Toothbrush for seals
Old (unknown source) Full cleaning + dry soda for 24 hours 12+ hours Activated carbon

Method 4: Soda “bombs” for hard-to-reach places

In refrigerators with a system No Frost or models with hidden ventilation ducts (for example Samsung RB37J5240SA, LG GA-B489YVQZ) the smell can “hide” in places where it is difficult to reach with a sponge. What will help here soda "bombs" is hissing tablets that penetrate into the cracks and neutralize the smell from the inside.

How to make:

  1. Mix 4 tablespoons of soda and 2 tablespoons of lemon acid.
  2. Add 1 tablespoon of water - you should get a thick paste.
  3. Form small balls (the size of cherries) and place them on a plate.
  4. Place the plate in the refrigerator on the bottom shelf and close the door.
  5. After 30-40 minutes, when the hissing stops, ventilate the refrigerator.

The reaction between soda and citric acid releases CO₂which displaces odor molecules from the cracks. This method is especially useful for refrigerators with automatic defrostingwhere odors often circulate through the air duct system.

What to do if the smell remains after cleaning?

If the smell persists after treating with soda, check:

1. Drainage hole —organic matter often accumulates there. Clean it with a cotton swab dipped in soda solution.

2. Back wall (in models with a drip system). There may be mold there.

3. Products - sometimes the smell comes from sealed bags (for example, with cheese or sausage). Check all packages.

If the problem is not solved, repeat cleaning with the addition of activated carbon (5-6 tablets in an open container for 12 hours).

Method 5: Prevention of odors with soda (for constant use)

To prevent the smell from returning, it is enough regularly use baking soda in small quantities. Here are some simple techniques:

  • 🧂 Soda bag in the door: Pour 2 tbsp. spoons of soda into a small cotton bag and hang it on a hook in the door. Change the soda once a month.
  • 🧼 Shelf Rinse: After each washing of the shelves, wipe them with a solution (1 tsp soda per 500 ml of water). This will prevent bacteria from accumulating.
  • 🥬 For boxes with vegetables: Sprinkle a thin layer of baking soda on the bottom of the drawer before placing food. Soda will absorb excess moisture and odors.

For refrigerators with air ionizers (for example, Panasonic NR-BN30A1) soda will become an additional protection: the ionizer kills bacteria, and soda neutralizes organic connections.

⚠️ Attention: Do not store soda in the refrigerator in an open package - it will quickly absorb moisture and lose effectiveness. Always use sealed containers or fabric bags.

What not to do when cleaning the refrigerator with soda

Despite the safety of soda, there are several critical errorsthat can aggravate the problem:

  • 🚫 Mix soda with bleach - this releases toxic gas chlorine, dangerous for the respiratory tract.
  • 🚫 Use soda for aluminum parts (found in older models of refrigerators). It oxidizes the metal, leaving dark spots.
  • 🚫 Apply undiluted soda to plastic - abrasive particles can scratch glossy surfaces (relevant for models Samsung RF23J9011, Bosch KAN92VI30R).
  • 🚫 Closing the refrigerator immediately after processing - moisture promotes the growth of bacteria. Always ventilate for 10-15 minutes.

It is also not recommended to use soda for cleaning the freezer (if it is not combined with the refrigerator). At low temperatures, soda loses its absorbent properties. It is better suited for the freezer. data-i="235">cleaning the freezer vinegar solution (1:1 with water).

FAQ: Frequently asked questions about cleaning the refrigerator with soda

Can I use soda ash instead of baking soda?

No. Soda ash (Na₂CO₃) has a higher pH (11-12) and can damage plastic and rubber seals. Baking soda (NaHCO₃) is safe and non-aggressive.

How long should you keep the soda solution on surfaces?

For fresh odors, 15-30 minutes is enough. For old or moldy smells - 1-2 hours. If the smell remains after treatment, repeat the procedure or add hydrogen peroxide to the solution.

Will soda help if the smell comes from plastic containers?

Yes, but the containers need to be cleaned separately. Soak them in a soda solution (4 tablespoons per 1 liter of water) for 2-3 hours, then wash with detergent. For persistent odors, add 1 tablespoon of mustard powder to the solution.

Is it possible to clean a refrigerator with a No Frost system with soda?

Yes, but avoid getting the solution in ventilation holes. Use a soft brush or cotton swabs. After cleaning, turn on the “Vacation” mode (if available) for 1-2 hours to dry.

How often should you repeat soda cleaning?

For prevention - once every 1-2 months If the refrigerator is used intensively (for example, in a cafe or a large family), cleaning can be done once every 1-2 months. 3-4 weeks. It is enough to replace the dry soda in the bag once a month.
