Plastic parts in the refrigerator - shelves, drawers, door seals and internal panels - lose their original appearance over time. Yellowness, greasy deposits, mold and stubborn food stains not only spoil the aesthetics, but can also become a source of unpleasant odors or even bacteria. However, cleaning plastic requires a special approach: aggressive agents destroy the surface, and incorrect techniques lead to stains or microcracks.
In this article we will examine 12 proven methods washing plastic in the refrigerator - from improvised means (soda, vinegar, peroxide) to specialized chemicals. You will learn how to remove yellow spots from time, black mold in the corners and old fat without the risk of damaging the surface. We will also reveal three critical mistakeswhich 90% of housewives use when fridge care.
Why plastic in the refrigerator turns yellow and gets dirty
Plastic in the refrigerator does not just lose its whiteness - it absorbs pollution at the chemical level. Main reasons:
- 🔹 Oxidation under the influence of light. UV rays (even from a refrigerator light) destroy polymers, giving the plastic a yellow tint. Cheap models with low-quality ABS plastic are especially vulnerable.
- 🔹 Fat deposits. Steam from hot dishes settles on the walls, mixes with dust and forms a sticky film that attracts new contaminants.
- 🔹 Mold and bacteria. Moist environment + leftover food = ideal conditions for fungus. Black dots in the seal or at the bottom of the drawers are not dirt, but colonies of microorganisms.
- 🔹 Chemical reactions. Contact with acids (lemon juice, vinegar in large quantities) or alkalis (undiluted soda) leads to microdamage, where later dirt accumulates.
Interestingly, premium-class plastic (for example, in refrigerators Liebherr or Samsung Bespoke) turns yellow more slowly thanks to anti-UV additives and antibacterial coatings. But even it requires regular cleaning - at least once every 3 months.
⚠️ Attention: If the plastic becomes fragile or cracks appear on it, this is a sign of deep destruction of the material. In this case, cleaning is useless - the part must be replaced.
Preparing the refrigerator for cleaning: 5 mandatory steps
Before you start washing the plastic, the refrigerator must be properly prepared. Missing even one point can reduce all efforts to nothing:
- Disconnect from the network. Even if you have a model with
No Frost, the risk of a short circuit when moisture comes into contact with electricity remains. Pull the plug out of the socket! - Take out all the products. Place them in a cooler bag or wrap them in cling film with ice (if cleaning takes more than 2 hours).
- Remove all removable parts. Shelves, drawers, door balconies - everything that can be removed is cleaned separately (preferably in the bathtub).
- Ventilate the chambers. Leave the doors open for 15–20 minutes to allow the condensation to evaporate.
- Protect the seals. Wipe the rubber bands with a weak solution of vinegar (1:1 with water) to prevent the growth of bacteria during cleaning.
If the refrigerator is with the No Frost system, after cleaning it will take 6-12 hours to restore the temperature. For models with drip defrosting (Indesit, Atlant), this process will take 3-4 hours.
Top 5 home remedies for cleaning plastic
Do not rush to buy expensive chemicals - often improvised means help to cope with contamination. The main rule: all solutions must be warm (30–40°C), but not hot, so as not to deform the plastic.
| Medicine | Proportions | Efficiency | Exposure time |
|---|---|---|---|
| Baking soda | 3 tbsp. l. per 1 liter of water | ⭐⭐⭐⭐ Removes grease, lightens yellow spots |
15–20 minutes |
| Vinegar 9% | 1:1 with water | ⭐⭐⭐ Disinfects, removes odor, but may leave streaks |
10 minutes |
| Hydrogen peroxide 3% | Do not dilute | ⭐⭐⭐⭐⭐ Whites, kills mold, non-toxic |
5–7 minutes |
| Citric acid | 1 packet (20 g) per 0.5 liters of water | ⭐⭐⭐ Dissolves fat, refreshes, but can discolor colored plastic |
10–15 minutes |
| Toothpaste (white) | Apply pointwise | ⭐⭐ Polishes small scratches, but does not cope well with strong yellowness |
3–5 minutes |
For old contaminants combine funds. For example, first apply baking soda for 15 minutes, then rinse and wipe with peroxide. But vinegar and soda cannot be mixed - the reaction neutralizes their properties.

How to remove yellow stains from plastic: 3 methods
Yellowness on plastic is not dirt, but oxidized polymers. Conventional detergents are powerless here. We need bleaching or restoring compounds:
Method 1: Hydrogen peroxide + soda (for strong yellowness)
Mix 2 tbsp. l. soda with 1 tbsp. l. peroxide to form a paste. Apply a thick layer to the stains, cover with cling film and leave for 1 hour. Then rinse off with a sponge. This method will return the whiteness to even 20-year-old plastic.
Method 2: Chlorine bleach (for white plastic only!)
Dilute Whiteness or Domestos in proportions 1:10 with water. Apply with a brush for 5-7 minutes, then rinse thoroughly. Do not use on colored plastic —chlorine will discolor the pigment!
⚠️ Attention: Chlorine emits toxic fumes. Wear gloves and a respirator, and after processing, ventilate the refrigerator for at least 2 hours.
Method 3: Melamine sponge (for delicate surfaces)
Melamine acts as a soft abrasive, removing the top oxidized layer of plastic. Wet the sponge with water and gently rub the yellow areas without pressure. After treatment, wipe the surface with a damp cloth.
What to do if the plastic has turned yellow from the inside (in two-chamber refrigerators)?
In this case, stains often appear due to contact with freon (in models with a top freezer). Only replacing the panel will help here - bleaches will give a temporary effect (1-2 months), but the problem will return. Contact the service center for advice on the warranty (in some cases this is a sign of a manufacturing defect).
Removing mold and black spots
Mold in the refrigerator is not only an aesthetic problem, but also health risks. Fungal spores can cause allergies and respiratory problems. They need to be dealt with comprehensively:
- Mechanical cleaning. Use the rough side of a sponge or a toothbrush to remove visible plaque. For hard-to-reach places (for example, a drainage hole), use cotton swabs.
- Disinfection. Wipe the surfaces with undiluted vinegar or solution Chlorhexidine (sold at the pharmacy). These products kill spores by 99.9%.
- Prevention. After cleaning, place a moisture absorber (for example, Silica Gel) or an activated carbon tablet in the refrigerator.
If mold appears on sealing rubber, it can be restored with WD-40 (unexpected, but it works!). Spray the product onto a rag, wipe the elastic, then rinse with soap and water. WD-40 softens the rubber and removes microcracks where bacteria settle.
Professional products: what to choose
If home methods do not help, it’s the turn of specialized chemistry. The main thing is to choose products marked "for plastic" or "for refrigerators":
- 🧴 Topperr 3004 —a foam cleaner for professional cleaning. Removes grease, yellowness and limescale. Suitable for No Frost.
- 🧴 Sano Refrigerator Cleaner —spray with an antibacterial effect. Does not require rinsing, leaves a protective film.
- 🧴 Mellerud for refrigerators - a German product with a biodegradable formula. Safe for food plastic.
- 🧴 Cillit Bang "Clean refrigerator" is a budget option with a whitening effect. Strong odor, need to be washed off thoroughly.
When using professional products, follow the instructions on the package. For example, Topperr 3004 is applied for 3-5 minutes, and Sano it is enough to spray and wipe off after 30 seconds.
⚠️ Attention: Do not use oven cleaners (Scholl, Amway) - they contain aggressive alkalis that corrode the plastic of the refrigerator.
What not to do when cleaning plastic
Even the most effective cleaning methods can be harmful if you break the rules. Here three critical errorsthat lead to irreversible damage to plastic:
- 🚫 Use abrasive powders (Pemolux, Komet). They scratch the surface, and the dirt then eats in even deeper.
- 🚫 Wash with hot water (above 50°C). The plastic is deformed and the seals lose their elasticity.
- 🚫 Leave the products longer than the specified time. For example, chlorine or vinegar corrode the top layer of plastic in 30+ minutes.
Also avoid hard brushes i metal sponges —they leave microcracks. For hard-to-reach places (for example, ventilation grilles), use toothpicks or cotton sticks.
FAQ: Frequently asked questions about cleaning plastic in the refrigerator
Can bleach be used for colored plastic?
No! Chlorine and oxygen bleaches will discolor the pigment. For colored parts, use hydrogen peroxide or special cleaners for plastic (for example, Sano).
How to wash plastic from glue (for example, from stickers)?
First remove the remaining glue vegetable oil (apply for 10 minutes, then wipe off with a napkin). Then wipe the surface with alcohol or WD-40 to remove the greasy film.
Why does the smell remain after cleaning with vinegar?
The vinegar smell is neutralized with soda. After treatment, wipe the surfaces with a soda solution (1 tablespoon per glass of water), then ventilate the refrigerator with the door open for 1-2 hours.
How to clean plastic in a refrigerator with a No Frost system?
The principle is the same, but Do not pour water into the drainage hole (this can damage the evaporator). Use sprays or wet wipes, avoiding getting liquid on the back wall.
How much does professional cleaning cost? refrigerator?
Depending on the region and the degree of contamination, the price varies from 1,500 to 4,000 rubles. The price usually includes disassembly, disinfection and treatment with an antibacterial composition. For models Side-by-Side the price is 20–30% higher.
