Defrosting a refrigerator is a necessary process, but it always leaves behind unpleasant consequences: puddles on the floor, ice in hard-to-reach places and, most importantly, persistent odors mixed with mustiness. Even if you carefully drained the water and wiped the shelves, after a few days plaque may appear and plastic parts will lose their original shine. In this article we will look at how to clean a refrigerator after defrostingso that it not only shines clean, but also retains freshness inside for a long time.
The problem is that ordinary detergents often cannot cope with biological contamination (mold, bacteria), and aggressive chemicals can damage the rubber seals or the chamber coating. We tested dozens of methods - from grandma's recipes to professional formulations - and selected those that really work. We will pay special attention safety for food: after cleaning, the refrigerator should be ready to load food without additional ventilation.
It is important to take into account the material of the internal surfaces. For example, know frost with an antibacterial coating cannot be cleaned with abrasives, and for glass shelves not all sprays are suitable. In order not to spoil the equipment, we have divided recommendations by type of refrigerator and type of contamination.
1. Preparing the refrigerator for cleaning: what to do before washing
Before grabbing a sponge, you need to properly prepare the refrigerator. This will save time and prevent mold from reoccurring.
Turn off the power and remove all removable elements: shelves, drawers, grilles. It is better to wash them separately in warm water. If there is ice left in the freezer, do not try to break it off with a knife - use plastic scraper or hair dryer at minimum power (keep at a distance of 20 cm).
- 🔌 Unplug and let the refrigerator stand for 10-15 minutes - this will prevent power surges when turned on.
- 🧊 Remove the remaining ice: place a pan of hot water in the freezer and close the door for 5 minutes. The ice will thaw on its own.
- 📦 Take out all the products and put them in a cooler bag or wrap them in towels with ice.
- 🧽 Prepare the tools: soft sponges, microfiber cloths, toothbrush for joints, rubber gloves.
If there was strong smell in the refrigerator (for example, from spoiled fish), before washing, put an open box inside for baking soda for 1-2 hours - it will absorb some of the unpleasant aromas.
2. Folk remedies: how to clean a refrigerator without chemicals
If you prefer environmentally friendly methods or are afraid that chemicals will remain on surfaces, use proven home recipes. They cope with fatty deposits, mold and musty odorwithout harming health.
Vinegar solution (9%) - universal disinfectant. Dilute it with water in a 1:1 ratio, apply to surfaces and leave for 10 minutes, then rinse with clean water. Vinegar kills up to 80% of bacteria and eliminates odors, but is not suitable for aluminum parts (may cause darkening).
Citric acid (2 tbsp per 1 liter of water) perfectly dissolves limescale and refreshes the plastic. To enhance the effect, add 1 tsp. soda. This composition will also help whiten yellowed rubber seals.
- 🍋 Lemon + salt: cut the lemon in half, dip in salt and wipe the glass shelves - this will remove stains and add shine.
- ☕ Coffee grounds: after washing, wipe the inner walls with dry coffee grounds - they absorb odors for 2-3 weeks.
- 🧂 Soda + hydrogen peroxide: a slurry of these components (2:1) will remove even old mold in the corners.
It is strictly forbidden to use bleach or “White” to wash the refrigerator - even after thorough rinsing, its particles remain on the surfaces and can penetrate into the products, causing poisoning.
3. Professional detergents: what to choose for different surfaces
If traditional methods fail to remove stains, it’s the turn of specialized chemistry. The main rule: choose products marked "for refrigerators" or "food-safe" (safe for contact with food).
| Surface type | Recommended product | Features of application |
|---|---|---|
| Plastic (shelves, drawers) | Sano Refrigerator Cleaner, Topperr 3101 | Apply for 5-7 minutes, rinse without abrasives |
| Glass | Cillit Bang "Antifat", Mr. Proper for glass | Use with microfiber, avoid contact with rubber bands |
| Stainless steel (external panels) | Weiman Stainless Steel Cleaner | Apply in the direction of the “fibers” of the metal |
| Rubber seals | Mellerud for seals, WD-40 (only for the outside!) | Lubricate with silicone grease after cleaning |
For heavy contamination (for example, after leakage of meat juice) suitable Sanita Antibacterial gel. It destroys protein deposits and kills E. coli and Salmonella. Apply it spotwise for 10 minutes, then rinse with plenty of water.
If the refrigerator has a system No Frost, avoid products with abrasive particles - they may damage the micropores of the antibacterial coating. For such models, it is better to use foam sprays (for example, Electrolux Fridge Cleaner), which do not require intense friction.
What should not be used to clean the refrigerator?
It is prohibited to use: acetone, solvents, powdered cleaners (such as Pemolux), hard metal sponges, toilet or plumbing products (they contain acids that corrode plastic).
4. How to wash the rubber seal: saving from mold and cracks
The seal is the most vulnerable spot of the refrigerator. Here fungus, dirt and fataccumulate, and improper cleaning can lead to cracking of the rubber and loss of tightness. If the seal is blackened or covered with a white coating, proceed according to this scheme:
- Removing plaque: wipe the elastic band with a cotton pad soaked in soda solution (3 tbsp per 1 liter of water). For heavy soiling, use toothbrush.
- Disinfection: apply hydrogen peroxide (3%) for 5 minutes, then rinse. It kills mold spores.
- Lubrication: after drying, treat the gum with silicone grease (for example, WD-40 Specialist Silicone) - this will prevent cracking.
If the seal is detached from the body, carefully heat it hairdryer (temperature no higher than 50°C) and press for a few minutes. For fixation, you can use 3M double-sided tape, but not glue - it can damage the plastic.
Remove plaque once a month|Check tightness with a “dollar bill” (if it is easily pulled out, the seal is faulty)|Lubricate with silicone after each defrosting|Do not use aggressive detergents-->
⚠️ Attention: if the elastic appears deep cracks or it has lost elasticity, it must be replaced. Continuing to operate the refrigerator with a damaged seal leads to increased energy consumption (up to 30%) and ice formation on the back wall.
5. Eliminating odors: how to get rid of mustiness for a long time
Even after thorough washing, an unpleasant odor may remain in the refrigerator. This is due to the fact that bacteria and fungi penetrate into the micropores of plasticand regular cleaning does not remove them. To solve the problem, combine mechanical cleaning with odor absorbers.
Absorbents (absorb odors):
- 🧂 Soda: place the open pack on the middle shelf for 2-3 days.
- ⚪ Activated carbon (10 tablets in a saucer) - change once a week.
- 🍊 Citrus peel: dry the orange or lemon peels and place them in the corners.
Disinfection (destroys the source of odor):
- 💨 Ozonizer: if possible, use a household ozonizer (for example, AirComfort XJ-3000) - it kills bacteria and odors in 20 minutes.
- 🌿 Essential oils: add 5 drops of oil tea wood or lavender to rinse water.
For strong odors (for example, after storing fish) use carbon filter (for example, Fridge It). It works for up to 6 months and removes even ammonia and hydrogen sulfide compounds.
6. Cleaning external surfaces and back walls
External care is no less important than internal care. Dust on condenser (rear grille) increases energy consumption by 15–20%, and dirt on the handles and panel spoils the appearance. Here's how to properly wash the outside of the refrigerator:
Back wall:
- Unplug the refrigerator and move it away from the wall.
- Use a vacuum cleaner with a narrow attachment to remove dust from condenser and ventilation holes.
- Wipe the grille with a damp sponge dipped in soapy water (do not use copious amounts of water!).
- Dry the surface with a hairdryer or let it dry naturally way.
Door and handles:
- 🧼 For stainless steel use special polishes (for example, Weiman Stainless Steel Wipes).
- 🎨 For plastic panels a solution of water with vinegar is suitable (1:3).
- 🔄 Wash your handles with antibacterial soap - more germs accumulate on them than on the toilet!
⚠️ Attention: never pour water on the back wall of the refrigerator with open condenser (in models without protection). data-i="245">Attention short circuit. If you are not sure, it is better to use a dry vacuum cleaner.
7. Features of cleaning refrigerators with the No Frost system
Refrigerators No Frost require defrosting, but this does not mean that they do not need to be cleaned. In such models, improper cleaning can disrupt the operation of the ventilation system. Dirt and bacteria accumulate in the air ducts. What can be done: Dirt and bacteria accumulate in air ducts, and improper cleaning can disrupt the operation of the ventilation system.
What you can do:
- 🧹 Use soft cloths products without abrasives.
- 💨 Vacuum the ventilation holes (without pressing!).
- ❄️ Wipe the evaporator once every 6 months (back wall) with a solution vinegar.
What not to do:
- ❌ Wash under running water - this will damage the electronics.
- ❌ Use sharp objects to clean air ducts.
- ❌ Apply detergents directly to ventilation grilles.
Ideal for No Frost perfect fit steam cleaners (for example, Kärcher SC 2). wipe the surfaces with a dry cloth.
How to check the operation of No Frost after cleaning?
Turn on the refrigerator at maximum cooling mode. After 2 hours, check whether cold air is blowing from the ventilation holes (you can put your hand or a sheet of paper up. If the flow is weak, it may be clogged). air ducts.
8. Prevention: how to maintain cleanliness between defrosts
To avoid having to spend hours on general cleaning, just follow simple rules:
- Weekly cleaning: wipe the shelves and walls with a damp cloth with vinegar solution (1 tbsp per 1 liter of water).
- Food storage: use containers with lids - this will prevent liquids from splashing.
- Checking the seal: once a month, inspect the rubber for cracks and wipe it glycerin.
- Ventilation: do not place the refrigerator close to the wall - there must be a gap of at least 5 cm.
For absorption. odors keep in the refrigerator package with zeolite (mineral absorbent) or special tablets (for example, Fridge FreshThey work for up to 3 months.
If your model has a function "Vacation" (for example, in Liebherr or Bosch), turn it on during long periods of absence - this will prevent the formation of mold.
