Scratches on a laptop screen are a problem that every second user faces after 1-2 years of active use. Even careful handling does not guarantee protection: one careless movement of the keyboard, a grain of sand getting under the cover or contact with keys in a bag is enough for noticeable defects to appear on the matte or glossy finish. But don’t rush to change the display or put up with annoying streaks - in 80% of cases, scratches can be fixed on your own.
This article is not about temporary “camouflage” solutions like stickers or gels, but about full polishing, restoring the transparency and smoothness of the screen. We'll sort it out physical and chemical methods, suitable for different types of coatings (from IPS to OLED), we will tell you about professional kits and improvised means, and also warn about critical errors that will turn minor scratches into hopeless cracks. All recommendations are based on the experience of service centers and tests of popular bloggers, such as Zach’s Tech Turorials And Linus Tech Tips.
Why do scratches appear and can they be removed without leaving a trace?
The laptop screen consists of several layers: a protective coating (most often hot pressed glass or polycarbonate), polarizing film, matrix and backlight. Scratches affect only the top layer, but their depth determines how successful the polishing will be:
- 🔹 Microdamage (up to 5 microns deep) - almost invisible when the screen is off, but scatters light. Eliminated in 10-15 minutes using paste GOI or toothpaste.
- 🔹 Medium scratches (5-20 microns) - noticeable at an angle, cling to with a fingernail. Requires multi-stage polishing with transition from abrasives
#1000to#3000. - 🔹 Deep furrows (over 20 µm) - visible under direct illumination, may affect the polarization layer. Complete removal is impossible, but you can reduce their visibility by 60-70%.
Key success factor - screen covering type:
- 📱 Glossy screens (for example, on MacBook Pro or Dell XPS) are easier to polish, but require delicate compounds without aggressive solvents.
- 📺 Matte screens (like Lenovo ThinkPad or HP EliteBook) have an anti-reflective coating that is easy to damage. This requires specialized pastes, for example, PolyWatch.
⚠️ Attention: If the scratch is accompanied rainbow stains when the screen is on, this is a sign of damage to the polarizing film. Polishing is powerless here; the display module will need to be replaced.
Preparation for polishing: tools and safety precautions
Before you get started, make sure you have everything you need. Here is the minimum set for safe polishing:
| Category | Tool/material | What is it for? | Alternative |
|---|---|---|---|
| Abrasives | Sandpaper #2000-#3000 (water resistant) |
Removing deep scratches | Microfiber cloths with diamond paste |
| Polishing compounds | Pasta GOI (green) or PolyWatch | Restoring transparency | Toothpaste without granules (eg. Colgate Total) |
| Protection | Masking tape 3M | Screen frame insulation | Electrical tape (less reliable) |
| Care | Spray iCloth or distilled water | Cleaning before polishing | Alcohol solution (no more than 30%) |
Preparation process:
- Turn off the laptop and disconnect the battery (if possible). It is prohibited to work with the device turned on!
- Cover the screen frame with masking tape, leaving only the damaged area exposed. This will protect the plastic from the chemical effects of the pastes.
- Clean the screen from dust and grease using a microfiber cloth soaked in distilled water. Don't use paper towels - they leave microfibers!
- Glossy
- Matte (anti-glare)
- I don't know
- Other
⚠️ Attention: If your laptop has touch screen (like Microsoft Surface or HP Spectre), polishing may interfere with the operation of the touch panels. In this case, contact the service center - independent intervention will void the warranty.
Step-by-step instructions: how to polish a laptop screen
The polishing algorithm depends on the depth of the scratches. Below is a universal technique suitable for 90% of cases. If you have OLED screen (for example, on Asus ZenBook Pro Duo), skip the steps with abrasives - these displays are thinner and more sensitive to mechanical stress.
Step 1: Removing Deep Scratches (If Necessary)
For grooves that catch with your fingernail:
- Wet the sandpaper
#2000in distilled water. - Using circular movements with light pressure, treat the scratch for 30-40 seconds. Movements should be chaoticto avoid the formation of new risks.
- Rinse the screen with water and dry with a cloth.
Step 2: Basic Polishing
Use paste GOI or its analogues:
- Apply a small amount of paste to a microfiber cloth.
- Polish the screen in a circular motion for 2-3 minutes, gradually reducing pressure.
- Remove any remaining paste with a dry cloth and inspect the screen from different angles.

Step 3: Finishing
To restore anti-glare properties (relevant for matte screens):
- 🧴 Apply a thin layer of car glass wax (for example, Turtle Wax).
- 🔄 Polish with a napkin to a mirror shine.
- 🕒 Let it dry for 10-15 minutes before turning on the laptop.
If streaks remain after polishing, wipe the screen with a cloth soaked in a vinegar solution (1 part vinegar to 3 parts water). This will remove any remaining grease and paste.
Top 5 polishes: what to choose in 2026
The market offers dozens of screen polishing compounds, but not all are safe for laptops. We tested 12 products and selected the best ones in terms of price/effectiveness ratio:
| Means | Screen type | Benefits | Disadvantages | Price (≈) |
|---|---|---|---|---|
| PolyWatch | Matte/glossy | Versatile, does not damage the coating | Takes a long time to dry (up to 1 hour) | 1 200 ₽ |
| GOI paste (green) | Glossy, OLED | Fast results, suitable for deep scratches | Requires skill (can be ground) | 800 ₽ |
| Displex | Matte (anti-glare) | Restores factory texture | Not sold in regular stores | 1 500 ₽ |
| Toothpaste Splat Professional | Glossy (minor scratches) | Cheap and accessible | The effect lasts 1-2 months | 150 ₽ |
| Novus Plastic Polish #2 | All types | Professional composition, reusable | High price | 2 000 ₽ |
For a budget solution, toothpaste is suitable, but remember: it contains mild abrasives that will thin out the protective coating over time. The best choice for most users is PolyWatch or GOI.
What to do if polishing doesn't help?
If after 2-3 attempts the scratches are still noticeable, consider alternative options:
1. Replacement of protective glass (relevant for laptops with Gorilla Glass, for example, Razer Blade). Cost: from 3,000 ₽.
2. Matte film sticker (will hide defects, but reduce screen brightness by 10-15%).
3. Professional polishing service (use diamond pastes and UV curing). Price: from 2,500 ₽.
What not to do when polishing: 7 critical mistakes
Even experienced users sometimes make fatal mistakes that lead to irreversible damage. That's what strictly prohibited:
- 🚫 Use household chemicals (For example, Mr. Proper or Cillit Bang). Alkalis and acids destroy the anti-reflective coating.
- 🚫 Polish the included screen. Heating the matrix accelerates chemical reactions, which can lead to film delamination.
- 🚫 Use sandpaper rougher
#1500. This will lead to new, deeper scratches. - 🚫 Press on the screen with a force of more than 0.5 kg. Matrices IPS And OLED sensitive to mechanical pressure.
- 🚫 Use paper napkins or towels. They leave micro-scratches and fibers.
- 🚫 Polish the screen without pre-cleaning. Sand grains act as an abrasive and increase damage.
- 🚫 Apply the paste directly to the screen. Always use a mediator - a microfiber cloth.
⚠️ Attention: If your laptop has 3D screen (like Acer Predator Helios), polishing may disrupt the stereo effect. In this case, the only solution is to replace the display.
Prevention: How to protect your screen from scratches in the future
Polishing is a temporary solution. To avoid repeated damage, follow these rules:
- 💻 Use a padded case (For example, Thule Gauntlet or AmazonBasics). It will protect the screen from contact with the keyboard when closing.
- 🧴 Apply a protective coating once every 3 months. Spray will do iCloth Screen Coating or car wax.
- 🧹 Clean your keyboard regularly from dust and crumbs. Use a can of compressed air or sticky cleaner Oxo Good Grips.
- 📦 Transport your laptop in a separate compartment of your backpack, away from keys and other hard objects.
Can be glued on for added protection protective film. Optimal options:
- 🔹 Spigen Tempered Glass — for glossy screens (thickness 0.3 mm).
- 🔹 3M Privacy Screen — matte film with anti-spy effect.
- 🔹 Belkin Anti-Glare - Reduces glare and protects against scratches.
Even the most careful polishing will thin out the screen's protective coating. To extend the life of your display, combine mechanical protection (cases, films) with chemical protection (waxes, sprays).
FAQ: Frequently asked questions about polishing laptop screens
Can you polish your laptop screen with toothpaste?
Yes, but only if it's pasta without abrasive granules (For example, Splat Whitening Plus or Colgate Total). Gel pastes are not suitable. The effect will be short-term (1-2 months), since the toothpaste does not restore the protective coating, but only masks scratches. For long-term results, use professional formulations like PolyWatch.
How long does it take to polish a screen?
The time depends on the depth of the scratches:
- 🔹 Small scratches: 15-20 minutes.
- 🔹 Medium damage: 40-60 minutes (including drying).
- 🔹 Deep furrows: up to 2 hours (re-treatment may be required).
Take your time - quality is more important than speed. Polishing in a hurry often leads to the appearance of new defects.
Is it possible to polish a laptop screen with an OLED matrix?
Yes, but with caution. OLED screens (for example, in Alienware m15 or MSI Prestige) thinner and more sensitive to pressure. Use only soft pastes (For example, Novus #1) and avoid rougher abrasives #2500. Also, do not polish the screen for more than 5 minutes at a time - overheating may cause pixel burnout.
What should I do if the screen becomes cloudy after polishing?
Turbidity appears due to:
- For remaining paste, wipe the screen with a cloth soaked in distilled water.
- Damage to anti-reflective coating - Apply a thin layer of car glass wax.
- Too aggressive polishing - in this case, only replacing the protective glass will help.
If the haze does not disappear, contact a service center - the polarizing layer may be damaged.
How often can you polish your laptop screen?
Frequent polishing wears away the protective coating. Recommended frequency:
- 🔹 Glossy screens: no more than 1 time in 6 months.
- 🔹 Matte screens: no more than 1 time a year (anti-glare coating is more fragile).
- 🔹 OLED-displays: 1 time every 12-18 months.
After 3-4 polishings, the protective layer wears off so much that the screen becomes vulnerable to new scratches. In this case, it is more advisable to replace the display module.
