The metal body of the refrigerator is not only a stylish element of the kitchen, but also a magnet for minor damage. Even careful use does not prevent scratches from appearing: they are left by keys in pockets, accidental impacts with dishes, moving equipment, or pets. Defects are especially noticeable on glossy models Samsung RB, LG Instaview or Bosch KIN, where the metal is covered with a thin protective layer.
The main problem is that scratches not only spoil the appearance, but can also become a source of corrosion if the factory coating is damaged. However, do not rush to call a specialist or buy a new refrigerator. Most defects can be eliminated yourself - from small cobwebs to deep furrows - using improvised means or inexpensive materials from a hardware store. In this article we will look at 7 working methodsincluding those that are suitable for refrigerators with system No Frost and inverter compressors.
Before you start repair, it is important to assess the depth of the scratch. Run your fingernail along it: if it “clings”, it means that the damage has reached the metal, and radical measures will be needed (putty, painting). If the defect is barely noticeable, polishing or masking with special compounds is enough.
1. Damage assessment: when you can do without painting
Not all scratches require drastic measures. Surface defects (up to 0.1 mm deep) can often be masked without a trace, while deep grooves will require restoration of a layer of paint. To avoid wasting time and money, perform a simple test:
- 🔍 Visual inspection: hold a bright flashlight to the refrigerator at an angle of 30–45°. Small scratches will cast a faint shadow, deep scratches will cast a clear stripe.
- 💅 Tactile test: swipe the damage with a plastic card (not your fingernail!). If the card gets stuck, the scratch is deep.
- 💧 Test with water: drop water on the defect. If the drop spreads unevenly or is absorbed, the factory coating is damaged.
Pay special attention to refrigerators with antibacterial coating (for example, Hitachi R-BG410 or Panasonic NR-BX). In these models, the top layer often contains silver ions, and damage to it can reduce the protective properties. In this case, it is better to paint over even minor scratches with a special varnish.
⚠️ Attention: If the refrigerator is under warranty, any independent intervention (especially using abrasives or paint) may cause a refusal of service. Check the terms of the warranty card - some brands (Liebherr, Miele) allow cosmetic repairs without loss of warranty.
| Type of scratch | Depth | Recommended elimination method | Cost (RUB) |
|---|---|---|---|
| Microdamage (cobwebs) | up to 0.05 mm | Polishing with wax or GOI paste | 100–300 |
| Medium (palpable with a fingernail) | 0.05–0.2 mm | Pencil for removing scratches or gel corrector | 300–800 |
| Deep (to metal) | from 0.2 mm | Putty + spray painting | 800–2500 |
| Through (rust) | more than 0.5 mm | Professional repair or panel replacement | from 3000 |
2. Minor scratches: polishing and masking without risk
To eliminate shallow defects (up to 0.1 mm), gentle methods are suitable that do not damage the factory coating. The main rule is do not use abrasives larger than 2000 grit (for example, sandpaper) so as not to aggravate the problem.
Method 1: Wax for furniture or car
Hard wax (for example Turtle Wax or Sonax>) fills microcracks and creates a protective film. Suitable for matte and glossy surfaces. Algorithm of actions:
☑️ Polishing with wax
For refrigerators with textured metal (for example, Smeg FAB32), choose wax with a matte effect so as not to create an uneven shine.
Method 2: Toothpaste or soda
This is an emergency method if there are no specialized means at hand. Use only white paste without granules (for example, SPLAT Bleaching>) or baking soda diluted with water to a paste. Apply with a soft cloth, avoiding strong pressure.
⚠️ Attention: Do not use this method on refrigerators with PVD coating (for example, Gorenje NRK6191>) - abrasives in paste may damage a thin decorative layer.
Method 3: GOI paste or metal polish
GOI paste (State Optical Institute) is a universal tool for polishing metals. Green paste (No. 2) is suitable for refrigerators green paste (No. 2) —it is softer than red and does not leave marks. An alternative is car polishes (3M Metal Polish or Autoglym Super Resin Polisher).
Technology:
- Apply the paste to felt fabric.
- Polish the scratch with straight movements (not in a circle!) for 1-2 minutes.
- Remove the residue with dry microfiber.
- Coat the polished area with a colorless metal varnish (for example, Kudo KU-7001).
3. Medium scratches: correctors and pencils
If the scratch is noticeable with a fingernail but does not reach the metal, use specialized masking products. They work on the principle of “filling” the defect with a pigment similar in color to the refrigerator body.
Method 4: Pencil for removing scratches
The simplest option is wax or gel based pencils (for example, Fix It Pro or Scratch Away). “metallic gray”, for Indesit or Atlant the shade “gray metallic” is suitable for Samsung - “anthracite”.
Instructions:
- 🧼 Clean the scratch with alcohol and dry.
- 🖊️ Carefully paint over the defect, slightly protruding edges.
- 🧻 Remove excess with a dry cloth after 5 minutes.
- 🔄 If necessary, repeat the procedure 2-3 times.
The service life of such repairs is 3-6 months. To prolong the effect, cover the treated area with colorless varnish.
Method 5: Gel corrector with a “liquid metal” effect
A more durable solution is gels based on acrylic resin (for example, Permatex Pro MetalThey not only mask the scratch, but also create a protective layer. Suitable for refrigerators). data-i="151">(for example, anti-corrosion coating (For example, Beko GNE114620X).
Advantages of the gel:
- ✅ Withstands wet cleaning.
- ✅ Does not turn yellow over time.
- ✅ Suitable for vertical surfaces (does not drip).
Apply the gel with the brush included in the kit, then polish with a soft cloth. Complete drying takes 24 hours.
What to do if the color of the pencil does not match?
If the shade of the corrector is lighter than the body, add a drop of black acrylic paint to it and mix. If it is darker, dilute with colorless varnish.
4. Deep scratches: putty and painting
If the scratch reaches the metal, ordinary masking will not help - over time, rust will appear in this place. In such cases, it is necessary to restore the protective layer using putty and paint. The method is suitable for refrigerators with a matte or semi-gloss surface (for example, Whirlpool ART 9810 or Electrolux ENN2854).
Method 6: Car putty + spray paint
For repairs you will need:
- 🔧 Putty for metal (Novol Plus 760 or Body 999).
- 🎨 Acrylic paint in a can (choose the color according to table below).
- 🧴 Primer (Kudo KU-7000).
- 📏 Emery paper 800–1200 grit.
Step-by-step instructions:
- Clean the scratch from dirt and degrease with acetone.
- Apply a thin layer of putty with a spatula, leveling it with the level of the body.
- After dry (1–2 hours), sand with sandpaper soaked in water.
- Coat with primer and let dry for 30 minutes.
- Apply paint in 2-3 layers with an interval of 15 minutes.
- Fix the result colorless varnish.
⚠️ Attention: Do not use nitro paints - they are aggressive to the factory coating of refrigerators. The optimal choice is acrylic or alkyd enamels.
Critical detail: for refrigerators with inverter compressors (for example, LG GA-B489) avoid paints with a strong odor - fumes can penetrate the system and damage the electronics. Work in a ventilated area or use water-based paints.
Method 7: Vinyl film or magnetic stickers
If there are a lot of scratches or they are located in a visible place (for example, on the door), consider the option with pasting with vinyl film. This is a radical solution that completely hides defects and allows you to update the design of the refrigerator.
Advantages of the method:
- ✅ Masks even through damage.
- ✅ Protects from new scratches.
- ✅ Easily removed without a trace.
For refrigerators with display on door (for example, Samsung Family Hub), choose a film with cutouts for controls or order individual printing.
5. Features of repair for different types of coatings
Refrigerators differ not only in the brand, but also in the type of metal coating: The choice of repair method depends on this. data-i="197">Coating type
| Coverage type | Examples of models | Recommended methods | What to avoid |
|---|---|---|---|
| Glossy metallic | Samsung RB37J5000, LG GC-B247 | Polishing with GOI paste, liquid metal | Abrasives coarser than 2500 grit |
| Matte metal | Bosch KIN86AF30, Siemens KG39NXI35 | Wax, corrector pencil, vinyl film | Glossy polishes |
| Antibacterial coating | Hitachi R-BG410, Panasonic NR-BX46 | Special varnish with silver ions | Aggressive solvents |
| PVD coating (imitation stainless steel) | Gorenje NRK6191, Liebherr CBPesf 4055 | Only non-abrasive products | Soda, toothpaste |
For refrigerators with two-layer coating (for example, Miele KFN 12923be sure to use a primer for metal before painting - this will prevent the paint from peeling off.
6. Prevention of scratches: how to protect the refrigerator
It is easier to prevent damage than to eliminate it. Here is 5 proven ways to protect the metal case:
- 🧲 Magnetic holders: use them to attach kitchen utensils (knives, seasonings) to avoid scratches from metal objects.
- 🧴 Protective coverings: apply transparent vinyl film or liquid glass to vulnerable areas (handles, corners) (Willson Glass Coat).
- 🐾 Barriers for animals: if there are cats or dogs at home, install soft silicone pads on the door.
- 🧹 Correct cleaning: wash the refrigerator only with soft sponges and microfiber, avoiding hard brushes.
- 🔄 Regular inspection: once a month, check the case for new scratches - it is easier to eliminate them at an early stage.
For refrigerators with touch panels (for example, Samsung RF23HCEDBSR) use special wipes for electronics - they do not contain alcohol and abrasives that can damage the display.
7. When to contact professionals
Not all defects can be eliminated by yourself if:
- 🔧 The scratch is deeper than 0.5 mm, and rusty metal is visible.
- 🎨 The refrigerator has unique coating (for example, mirror stainless steel or chameleon).
- ⚡ Damage is located next to
electronic unitordisplay. - 🔄 You tried 2-3 methods, but the scratch remained noticeable.
The cost of professional repairs in Moscow and St. Petersburg:
- Polishing - from 1,500 rubles.
- Local painting - from 3,000 rubles.
- Replacement of the panel - from 8,000 rubles.
⚠️ Attention: Some service centers refuse to repair scratches on refrigerators older than 5 years, citing the lack of original paints. In this case, look for craftsmen who specialize in body repair of household appliances.
FAQ: Frequently asked questions about scratches on the refrigerator
How to choose the paint color for the refrigerator?
Use the RAL color chart or contact your brand's service center indicating the model. For popular brands:
- Samsung — RAL 9006 (metallic white) or RAL 7016 (anthracite).
- LG — RAL 9003 (signalweiß) for classic models.
- Bosch/Siemens — RAL 9011 (graphite metallic).
For To make an accurate selection, take a photo of the refrigerator in daylight and show the photo in an auto enamels store.
Can WD-40 be used to remove scratches?
WD-40 does not delete scratches, but it can temporarily mask them due to its oily structure. However, after drying, the defect will become even more noticeable. For a long-term effect, use specialized products.
What to do if streaks appear after polishing?
Stains occur due to:
- Too coarse abrasive (use GOI paste No. 1 or No. 2).
- Insufficient cleaning of the surface before polishing (degrease with alcohol).
- Uneven pressure (polish with straight movements, not in a circle).
Re-polishing using finishing paste (for example, 3M Finesse-it).
How to remove scratches from a stainless steel refrigerator?
Stainless steel requires a special approach:
- For small scratches use polish for stainless steel (Bar Keepers Friend or Weiman Stainless Steel Polish).
- For deep - special grinding paste (Simichrome) and sandpaper 1000-1500 grit (sand along the grain metal!).
- After repairs, apply a protective coating (Stainless Steel Sealant).
Do not use chlorine-containing products - they destroy stainless steel.
How long does it take for paint to dry completely?
Time depends on the type of paint:
- Acrylic: 24 hours until complete polymerization (after 2 hours you can gently touch).
- Alkyd: 48 hours (the smell lasts up to 7 days).
- Epoxy: 72 hours (the most durable option).
Aerating or blowing with a fan will help speed up the process (but not with a hairdryer - it can cause bubbles!).
