Laptop screens quickly collect dust, fingerprints and oily marks. In most cases, a clean microfiber cloth and a small amount of distilled water are enough to clean them safely.
The safest method is simple: turn off the laptop, wipe the screen with a clean microfiber cloth, and use a little distilled water only if marks remain. Never spray water or cleaner directly on the screen.
Low-risk cleaning rule: use a soft cloth, very little liquid and very little pressure.
Stronger products, including isopropyl alcohol, are not suitable for every display surface. Check the instructions for your exact laptop model before using them.
What Do You Need to Clean a Laptop Screen?
You do not need many things to clean your laptop screen. You will need:
- A clean microfiber cloth
- Distilled water
- A second dry cloth, if available
For hard-to-remove marks, you may use a screen cleaner that is specifically safe for your laptop. Always check the manufacturer’s cleaning instructions before using alcohol or another cleaner.
What Should You Avoid?
| Item | Safe to Use? |
|---|---|
| Microfiber cloth | Yes |
| Distilled water | Yes, use a small amount on the cloth |
| Laptop screen cleaner | Check that it is safe for your exact screen |
| Isopropyl alcohol | Check your manufacturer’s guidance first |
| Tap water | Distilled water is better because it leaves fewer mineral marks |
| Tissue or paper towel | No — fibres can scratch or leave lint |
| Glass cleaner | No |
| Bleach or acetone | No |
| Spraying cleaner on the screen | Never |
If you are not sure what to use, start with a dry microfiber cloth and distilled water.
How to Clean a Laptop Screen Step by Step
1. Turn Off Your Laptop
Turn off the laptop and unplug the charger. A black screen also makes dust and fingerprints easier to see.
2. Remove Dust
Look for dust or small pieces of dirt. Remove them gently. Do not press hard, because tiny particles can scratch the screen when rubbed.
3. Wipe With a Dry Microfiber Cloth
Take a clean microfiber cloth and gently wipe the screen. For normal dust and light fingerprints, this may be enough.
4. Use a Little Distilled Water
Still see fingerprints or dirty marks? Put a small amount of distilled water on the microfiber cloth. The cloth should be slightly damp, not wet. Never spray water directly onto the laptop screen.
5. Wipe the Dirty Area Gently
Gently wipe the dirty part of the screen. Do not press hard or scrub. If a mark does not come off the first time, clean it again gently rather than using more pressure.
6. Dry the Screen
Use a clean, dry part of the cloth to remove water or streaks. Wait until the screen is completely dry before turning the laptop back on.
How to Clean Fingerprints Off a Laptop Screen
First, try a clean and dry microfiber cloth. If the fingerprints remain, put a little distilled water on the cloth and gently wipe them again.
Do not scrub the screen. More pressure can damage the surface and will not always remove the mark.
Can You Clean a Laptop Screen With Water?
Yes. Distilled water can be used to clean a laptop screen, but only use a small amount on the cloth. Do not pour or spray water directly onto the screen. Liquid can run into the edges of the laptop and damage internal parts.
Can You Use Tap Water?
It is better to use distilled water. Tap water contains minerals that can leave spots or streaks after it dries.
Can You Use Alcohol to Clean a Laptop Screen?
Sometimes, but not on every laptop screen. The safe answer is to check your brand and model guidance first. Different screen coatings and OLED panels can have different restrictions.
Lenovo permits water or a 50:50 mixture of isopropyl alcohol and distilled or deionised water for some computer LCD displays. ASUS allows a 70–75% isopropyl-alcohol-dampened microfiber cloth for many notebook displays. Both instructions require a damp cloth, never direct spraying. Lenovo guidance and ASUS guidance should be checked against your exact model.
If you are unsure, use a microfiber cloth and distilled water first.
How to Clean a Laptop Screen Without a Microfiber Cloth
If you do not have a microfiber cloth, use a clean, very soft, lint-free cloth. A clean cloth made for glasses or camera lenses can also work if it does not already have cleaner on it.
Avoid using:
- Paper towels
- Facial tissues
- Toilet paper
- Rough towels
- Dirty clothes
These can leave material behind or scratch the screen. If possible, wait until you have a microfiber cloth.
How to Remove Keyboard Marks From a Laptop Screen
Keyboard marks often appear when the screen touches the keyboard while the lid is closed. First, clean the marks with a dry microfiber cloth. If they remain, use a little distilled water on the cloth and try again gently.
If the marks still do not come off, stop rubbing. They may be small scratches, pressure marks or damage to the screen surface. Cleaning cannot remove that type of damage.
How to Clean a Laptop Screen and Keyboard
You can clean the screen and keyboard at the same time, but not in exactly the same way. For the screen, use a soft microfiber cloth and a little distilled water only when needed.
For the keyboard, use a soft brush or compressed air to remove dust and crumbs between the keys. Do not spray cleaner directly onto the keyboard or screen.
How to Clean Dell, Lenovo and ASUS Laptop Screens
How to Clean a Dell Laptop Screen
For a Dell laptop screen, start with a clean, dry microfiber cloth. Dell’s screen guidance also permits a cloth lightly dampened with water for marks that remain after dry cleaning. Dell says not to spray liquid directly onto the product. See Dell’s official cleaning guidance for its current instructions.
How to Clean a Lenovo Laptop Screen
For a Lenovo laptop screen, start with a soft, dry cloth. Lenovo’s general computer-cleaning guidance allows water or a 50:50 mix of isopropyl alcohol and distilled or deionised water for some LCD displays. Check the instructions for your Lenovo model before using alcohol.
How to Clean an ASUS Laptop Screen
ASUS recommends a soft microfiber cloth for laptop screens. Its notebook guidance allows a cloth dampened with 70–75% isopropyl alcohol or an LCD screen cleaner for many laptop displays. However, ASUS also gives different advice for some monitor and OLED surfaces, so the exact model instructions take priority.
What Should You Never Use on a Laptop Screen?
Avoid these common mistakes:
- Do not spray water directly on the screen.
- Do not use a very wet cloth.
- Do not press hard while cleaning.
- Do not use paper towels or tissues.
- Do not use normal household glass cleaner.
- Do not use bleach or acetone.
- Do not use alcohol without checking your model’s instructions.
- Do not turn the laptop on while the screen is still wet.
A simple rule to remember is: use a soft cloth, very little water and very little pressure.
How Often Should You Clean Your Laptop Screen?
There is no need to clean your laptop screen every day. Wipe away dust when you notice it. Use a slightly damp cloth only when there are fingerprints, oily marks or dirt that dry cleaning cannot remove.
Keeping your hands and keyboard clean can also help the screen stay clean for longer.

Cleaning Cannot Fix Every Screen Problem
Scratches, dead pixels, lines and pressure marks are display faults, not dirt. If you are inspecting a used laptop, use our used-laptop inspection guide and check the screen before buying.

What Is the Best Laptop Screen Cleaner?
For normal cleaning, a microfiber cloth and distilled water are usually enough. If you want to use a screen cleaner, make sure it is safe for your laptop screen.
Can I Use Windex on My Laptop Screen?
It is better to avoid normal glass cleaners such as Windex unless your laptop maker clearly says they are safe. Some glass cleaners contain chemicals that can damage screen coatings.

Not every eyeglass cleaner is safe for laptop screens. Check what is in the cleaner and your laptop manufacturer’s cleaning instructions before using it.

Yes. Turn the laptop off and gently clean the touchscreen with a soft microfiber cloth. Use a little distilled water if needed, but never spray water directly onto the screen.
Why Won’t a Mark Come Off My Laptop Screen?
If gentle cleaning does not remove a mark, it may not be dirt. It could be a scratch, pressure mark or damage to the top layer of the screen. Do not keep rubbing harder.
Final Tip
Cleaning a laptop screen does not need to be complicated. Start with a clean microfiber cloth. Use a little distilled water only when needed, never spray liquid directly onto the screen, and do not press hard. If a mark needs something stronger than water, check your laptop brand’s cleaning instructions first.
