Knowing how to clean a computer screen safely is all but required knowledge these days! With as many television screens, computer monitors, tablets, smartphones, and laptop screens we have scattered throughout our homes, that’s a lot of surface area for dust and fingerprints to build up on (not to mention germs and bacteria!)
The question of how to clean the screens on our devices is one of the most frequently asked questions about cleaning, and I hope to provide the answer(s) in this post! Here, you’ll learn the right way to clean a laptop screen, phone or tablet touchscreen, TV screen, or computer screen without damaging it.
Different types of screens have different needs when it comes to cleaning, so it’s important to know what kind of screen you’re dealing with before attempting to clean it. Luckily, you can easily determine which type of screen your device has by searching for the make and model online (or looking in the user manual!)
2 Important Rules To Clean Your Computer Screen Without Damaging It
While different types of screens may require different cleaning agents or methods, there are a couple of universal guidelines that are important to follow. First, you should always turn off your computer or device before you clean your screen. (This is mainly to protect the device, but a black screen makes it easier to see what you’re doing, too.)
Second, you should never spray liquids directly onto the screen, as spraying the screen directly can expose internal electronics to moisture. Instead, you should spray cleaning products onto a clean microfiber cloth, then use the damp cloth to wipe the surface of the screen.
How To Clean An LCD Computer Monitor Or Laptop Screen
If you use an external display monitor with your Mac or PC, there’s a good chance it has an LCD screen. Use very light pressure on the screen while cleaning it to avoid damaging its sensitive components.
- Use a microfiber cloth to gently remove dust from the screen. (Avoid using paper towels and cloths made of other materials to avoid damaging the sensitive surface.)
- If the screen is really grimy, spray a cleaning solution onto a cloth (not directly on the screen) and use it to wipe your screen clean. (I recommend my DIY screen cleaner, which I’ll show you how to make shortly!)
- Avoid using glass cleaners like Windex, or any cleaner that contains ammonia, alcohol, hydrogen peroxide, or acetone, on LCD screens, as they can leave behind a film or even do permanent damage to your screen.
How To Clean A Non-LCD Or Glass-Coated Screen
Most modern smartphones and tablets, as well as many Mac computers, have glass-coated screens. The glass coating makes them more durable than an LED or an LCD screen would be on its own, but it’s still important to clean them with care!
- Start by blowing on the screen (or using canned air) to remove any dust particles that could scratch the screen.
- Wipe the screen with a soft, lint-free microfiber cloth (ideally, the same kind you’d use to clean your eyeglasses).
- If fingerprints and smudges remain, dampen the cloth with a bit of alcohol or vinegar mixed with distilled water and use it to gently wipe the screen clean.
- Buff with a dry microfiber cloth to get rid of any streaks.
How To Clean A Mac With Nano-Texture Glass
Apple’s high-end desktop computers and displays, including Apple Studio Display, Apple Pro Display XDR, and some iMacs, have a special “nano-texture” glass screen. These models come with a special cleaning cloth that are meant to be used to clean the surface of your screen. To remove more stubborn smears, dampen the cloth with a bit of 70% isopropyl alcohol and use it to wipe down your screen with light pressure.
How To Make Your Own Screen Cleaner
You’ll need:
- Small spray bottle
- White vinegar or rubbing alcohol*
- Distilled water
*Use white vinegar if you’re cleaning LCD screens, or rubbing alcohol for glass-coated screens.
Directions:
To make a simple and effective screen cleaning solution, combine equal parts of white vinegar (or rubbing alcohol) and distilled water in a small spray bottle. Replace the spray top and shake well to mix.
How To Use Your DIY Screen Cleaner
A microfiber cloth can do quite a bit of cleaning on its own, so when it’s time to clean my phone or laptop screen, I like to start by using a clean, dry microfiber cloth to remove dust, lint, and oils. Then I spray the cleaner onto the cloth, and use the cloth to gently wipe the screen clean.
It works like a charm, too! The vinegar cuts through smears and smudges with ease, so give it a try for yourself!
BONUS: Cleaning Screen Protectors
Screen protectors are designed to prevent both messes and damage from reaching the actual screen of your device. Here are a few tips that can help you clean your screen protector up when it gets grimy. (If yours is very dirty or very damaged, it may be time to replace the screen protector!)
- Use a soft microfiber cloth to wipe the screen protector clean of dust and surface dirt.
- For more stubborn smudges, dampen the cloth with distilled water and gently wipe them away. (If you have a glass screen protector, you can use a bit of diluted alcohol or vinegar instead.)
How To Get Dust Out From Under A Screen Protector
- If there is dust under the screen protector, you’ll notice it right away. You’ll see the speck of dust surrounded by a halo of lifted glass or plastic.
- Lift a corner of the screen protector, use a piece of tape to pick up the dust, then replace the screen protector in its original position.
- If there’s a lot of dust or debris stuck under there, you may be able to remove the protector, wash it with some Dawn dish soap and water, then replace it once it’s dry.
