Plastic parts of the refrigerator over time lose their original white color, acquiring an unpleasant yellowish tint. This spoils the appearance of the equipment, makes it visually older and can become a source of irritation for the owner. The reasons for yellowing lie not only in the natural aging of the material, but also in improper care, exposure to sunlight or contact with aggressive detergents.
You can return the plastic of the refrigerator pristine whiteness without replacing parts - just use proven methods. In this article we will analyze causes of yellowingeffective methods of whitening (from home recipes to professional chemicals), and also give recommendations for prevention. We will pay special attention to safety - not all methods are suitable for ABS plasticfrom which most modern refrigerators are made.
Why refrigerator plastic turns yellow: 5 main reasons
Yellowing of plastic is not only an aesthetic problem, but also a signal that the material is beginning to deteriorate. The main factors that provoke color change:
- 🌞 Ultraviolet radiation —sun rays destroy the polymer chains in plastic, causing oxidation and color change. Refrigerators located close to windows or on balconies are especially vulnerable.
- 🧴 Aggressive chemistry - products with chlorine, acetone or ammonia corrode the top layer of plastic, making it porous and prone to absorbing dirt.
- 🕒 Natural aging —even with ideal care, plastic loses plasticizers, becoming brittle and yellowing (especially important for refrigerators older than 10 years).
- 🔥 Overheating or temperature changes —if the refrigerator is located next to a stove or battery, the plastic may deform and change color.
- 🍳 Fat and food stains - splashes of oil, soot and food particles penetrate into the micropores of the material, forming a coating that is difficult to remove.
Interestingly, plastic from different brands turns yellow in different ways. For example, parts of refrigerators Samsung and LG more often suffer from UV radiation, and plastic in models Indesit and Atlant is more susceptible to chemical attack due to a more porous coating. If your refrigerator turns yellow after 2-3 years of operation, most likely the problem is improper care, and not the quality of the material.
⚠️ Attention: Plastic with the addition brominated flame retardants (used in cheap models) turns yellow 2-3 times faster. Check the markings on the back wall of the refrigerator - if there is a designationHBCDorTBBPA, be prepared for more frequent maintenance.
Preparation of plastic for bleaching: what needs to be done before the procedure
Before you start bleaching, the plastic surfaces of the refrigerator must be properly prepared. This will increase the effectiveness of the procedure and protect the material from damage.
- Unplug the refrigerator and wait until it is completely defrosted (if you plan to clean the internal parts).
- Remove all removable elements: shelves, drawers, door seals (if they are plastic). It is more convenient to process them separately.
- Wash the surfaces with warm water and a mild detergent (for example, Fairy or Mif) to remove grease and dirt.
- Dry the plastic soft cloth or paper towels. Wet material absorbs bleaching compounds less well.
- Protect metal and rubber parts with masking tape - some bleaches can damage them.
To check the reaction of the plastic to the selected product be sure to carry out a test: apply a small amount of the composition to an inconspicuous area (for example, the back wall) and wait 10-15 minutes. If the color has not changed, the surface has not become sticky or rough, the product can be used.

Top 5 folk remedies for whitening refrigerator plastic
If the yellowing is not strong, improvised means will help return the plastic to its whiteness. They are safe for most types of plastic and do not require large expenses.
1. Baking soda + hydrogen peroxide
This is the most gentle method, suitable even for matte plastic surfaces. Soda acts as a mild abrasive, and peroxide acts as a bleach.
- Mix 3 tbsp. l. soda with 1 tbsp. l. 3% hydrogen peroxide to a paste.
- Apply the mixture to the yellowed areas with a soft sponge, avoiding strong friction.
- Leave for 20-30 minutes, then rinse warm water.
2. Toothpaste with whitening effect
Suitable for small areas (for example, yellowed corners or buttons). Choose paste without colored granules and menthol.
- Apply the paste to a damp sponge and gently rub the plastic in a circular motion.
- To enhance the effect, add a few drops of lemon juice.
- Rinse off after 10 minutes and dry the surface.
3. Vinegar solution
Vinegar dissolves grease deposits and brightens plastic, but it cannot be used on glossy surfaces as it can make them cloudy.
- Mix table vinegar (9%) s water in a ratio of 1:1.
- Wipe the plastic with the solution, then rinse with clean water.
- For a lasting effect, repeat the procedure 2-3 times with an interval of 1 day.
4. Citric acid
Effective against yellowness caused by fatty stains. Not suitable for plastic with small cracks - acid can penetrate inside and worsen yellowing.
- Dissolve 2 tbsp. l. citric acid in 1 liter of warm water.
- Wipe the plastic with a sponge soaked in the solution.
- Rinse after 15 minutes and apply a neutralizing solution (water + soda).
5. Melamine sponge
This is the only mechanical means that does not scratch plastic when used correctly. Melamine removes the top oxidized layer, returning the surface to its original color.
- Moisten the sponge in water and squeeze out.
- Treat the yellowed areas with light movements without pressure areas.
- After treatment, wipe the surface with a damp cloth.
⚠️ Attention: The melamine sponge cannot be used more than once every 3 months - it thins the plastic. Also avoid processing glossy panels - they may lose their shine.

Professional means: what to choose for lasting results
If traditional methods do not help, you should turn to specialized chemistry. Professional products act deeper, but require strict adherence to the instructions.
| Product | Type of plastic | Exposure time | Cost (for 500 ml) | Pros | Cons |
|---|---|---|---|---|---|
| Retrobright | ABS, polystyrene | 4–12 hours | 1 200–1 500 ₽ | Restores color at the molecular level | Requires a UV lamp for activation |
| Plastic Renew | All types | 10–15 minutes | 800–1 000 ₽ | Not requires rinsing | Pungent odor |
| Sonax Plastic Cleaner | ABS, polypropylene | 5–10 minutes | 600–700 ₽ | Removes yellowness and protects from UV | Expensive for regular use |
| Meguiar’s Plastic Polish | Glossy plastic | 15–20 minutes | 900–1 100 ₽ | Restores shine | Not suitable for matte surfaces |
For home use, the optimal choice is Plastic Renew -it is universal and does not require special equipment. If the plastic has turned yellow due to UV radiation, it is better to use Retrobright, but be prepared for a long procedure:
How does Retrobright work?
This gel contains hydrogen peroxide and catalysts, which, under the influence of UV rays (for example, from a nail lamp) decompose yellow pigments in plastic. The process takes several hours, but the result lasts up to 2-3 years. After processing, the plastic must be rinsed with water and a protective varnish applied (for example, Mod Podge).
When working with professional products be sure to use:
- 🧤 Rubber gloves (some compounds cause burns).
- 😷 A respirator or mask (vapors can irritate the respiratory tract).
- 🪟 An open window or hood (many products have a pungent odor).
What should not be done when bleaching the plastic of a refrigerator
Some methods that are recommended on the Internet can irreversibly damage the plastic:
- 🔥 Use acetone or solvents (for example,
646or647) - they dissolve the top layer of plastic, making it rough. - ☀️ Dry the plastic under direct sunlight after treatment - this will speed up the re-yellowing.
- 🧼 Use chlorine-containing products (type Whiteness) - chlorine destroys polymers and leaves stains.
- 🔪 Clean off the yellowness with a knife or metal sponge - this will lead to scratches in which dirt will accumulate.
- 🌡️ Heat the plastic with a hairdryer or boiling water - high temperature deforms the material.
You need to handle it with particular care sealing rubber bands on the refrigerator door. They are often made of thermoplastic elastomer (TPE)which cannot be treated with alcohol, vinegar or abrasives - this will lead to cracking and loss of elasticity.
⚠️ Attention: If after unsuccessful cleaning the plastic becomes sticky, wipe it alcohol solution (70%) - this will remove chemical residues. If the surface remains sticky for more than a day, you will have to replace the part.
How to prevent repeated yellowing: 7 rules of care
To keep the plastic of the refrigerator white longer, just follow simple recommendations:
- Wash the refrigerator regularly (at least once a month) with mild detergents (for example, Ecover or BioMio).
- Avoid direct sunlight —use curtains or move the refrigerator to a less lit place.
- Apply protective coatings —after bleaching, treat the plastic with colorless acrylic varnish (for example, Kudo).
- Do not place hot objects on the refrigerator (kettles, frying pans) - this leads to local yellowing.
- Ventilate room -high humidity accelerates the oxidation of plastic.
- Use covers for handles —they protect the most vulnerable areas from grease and dirt.
- Check the seals —if they have lost elasticity, replace them to avoid dirt getting inside.
For additional protection, you can use UV protective. sprays (for example, 303 Aerospace Protectant) They create an invisible film on the surface of the plastic that reflects ultraviolet radiation and prevents oxidation. This spray should be applied once every 2-3 months.
When bleaching does not help: signs of irreversible changes
Unfortunately, in some cases it is no longer possible to return the plastic to its original appearance. Signs that it is time to replace the part:
- 🔍 Deep cracks or chips —even after bleaching, they will be noticeable and become a source of new contaminants.
- 🧲 Plastic crumbles when press —this indicates a complete loss of plasticizers.
- 🎨 The color is uneven (spots, stains) —this means that the material is destroyed in different areas in different ways.
- 🔥 The part is deformed —for example, the door no longer closes tightly.
- 🧪 The smell of chemicals does not disappear even after repeated washing.
If the plastic on your refrigerator Samsung RL-34 or LG GA-B489 has acquired a grayish tint and has become brittle, most likely you will have to order new parts. In most cases, they can be found by article number in service centers or on AliExpress (for example, for models Atlant or Indesit spare parts cost from 500 to 2,000 ₽).
⚠️ Attention: When replacing plastic parts, check their compatibility with the refrigerator model. For example, handles from Samsung RB-30 are not suitable for Samsung RB-37 due to different fastenings.
