How to Clean Computer Screen & Monitor

If you still haven’t answered the question, “How to clean laptop screen?” We will outline all of the best ways.. Keeping your monitor clean is beneficial to your eyesight, your sanity and your time on your computer.

There is nothing worse than sitting down at your computer screen to find it covered in dust, fingerprints and smudges. Sometimes we see a smudge, wipe it away hoping it does the job instead of putting in a little elbow grease and getting the job down right. Keeping your monitor clean is beneficial to your eyesight, your sanity and your time on your computer.

Cleaning Computer & Laptop Monitor ( CRT & LCD )

There are two primary types of computer monitors nowadays: CRTs and LCDs. CRTs are huge, take up a lot of space and are much easier to clean than their counterparts. LCDs are generally flat panel, take up little space and are a bit more high-maintenance.

Cleaning a CRT Monitor

In order to clean a CRT, you can use a washcloth along with soap and water. Since most CRT computer monitors do not utilize a hard coating like televisions of the same make, you can also use paper towels to clean the screen with ease. You can use mild soap and water or a screen cleaning solution like Windex as long as you do not spray it directly onto the monitor. You want to spray it onto the cloth or towel, and then clean the monitor. When cleaning the outside of the monitor, use a damp cloth or towel and just dust it down. Again, do not spray or drip water onto the outside of the monitor or else you could short circuit it.

Cleaning a LCD Monitor

For a LCD monitor, you want to be very careful. Depending on the monitor, you will want to check out its manual for proper cleaning instruction. In general, you can buy LCD cleaning solutions and cloths to use, and most people opt to go that route. If you wish to clean it yourself, use a cotton-based cloth with a tiny drip of isopropyl alcohol. Make sure to put the alcohol on the cloth as opposed to dripping it onto the monitor. Use circular motions to clean the entire screen to eliminate smudges, dirt and other grime. Never use paper towels or any other abrasive cloth to clean the monitor, as LCDs are susceptible to scratches and other damage.

Cleaning your monitor is going to improve the picture quality and is much better on your eyes. Think about what it is like to clean dirty glasses and put them on, that is what it is like to clean a dirty monitor screen. Imagine the clearer picture you will get once you wipe away the dirt dulling your picture today.

Don’t Use Alcohol and Ammonia to Clean Your LCD Screen

Before we even get started with the steps to clean a computer monitor, I will issue forth this warning: do not use any products that contain alcohol or ammonia when cleaning an LCD screen. You also have to be wary of any other strong solvents. Because LCD screens, whether they be on a laptop or a desktop, are very susceptible to damage, scratching, and other problems, you have to be very careful what you use to clean them. Over the long run these chemicals will turn the screen yellow and it will eventually crack up the surface.


  • Ammonia
  • Ethyl alcohol
  • Methyl chloride
  • Acetone
  • Ethyl acid
  • Windex

Cleaning a Laptop Screen: Getting Started

So, now that the warning is out of the way, I still haven’t answered the question, “What is The Best Way to Clean a Computer Screen?” I will outline all of the best ways, but remember that there are also some companies who specialize in making wipes and solutions specifically for this purpose. If you want a truly spotless screen you may want to use some of their products. (They are detailed towards the end of this article.)


  • Water
  • Vinegar and water solution
  • Petroleum benzene

Distilled Water

If you’re going to do this on your own, the ideal screen cleaner is to simply use distilled water. (Avoid using tap water because it may have salts in it which will dry up on your screen.) You get a nice, soft cotton cloth and dip it in the water and simply wipe away all the dirt, dust, and other mysterious junk. Case closed? Maybe not…

Cleaning an LCD Monitor

Be delicate while you clean a laptop monitor, otherwise you greatly increase the odds of doing permanent damage to your screen or even the computer itself. For instance: never spray your cleaner directly onto an LCD screen. This is a recipe for disaster. There are electrical circuits on the edges that cannot be touched by liquid, even water. Instead spray first onto your cotton cloth, and only then is it safe to clean the screen with gentle, circular motions. There’s no need to go fast.

Vinegar and Water Solution

If your laptop screen just doesn’t seem to be giving way to simple water, then you can try mixing in 1 part white vinegar for every 1 part of water. You only need to use a very minimal amount of this or any cleaning solution when dealing with your screen. Remember that there is a downside to using too much: it may affect the screen, but more likely it could drip down into your actual CPU. These things are just not made to deal with liquid, so less is better. Always err on the smaller side because you can go back and add more if you find that the cloth and solution are not doing the job right.

Monitor Cleaning Products

Many people are of the opinion that the best way to clean a computer display is by using pre-made products, such as the ones featured to the right. This is definitely the safest way, as long as you make sure they are compatible with your type of screen (i.e. LCD, plasma, etc.). If you are unsure whether you’re going to cause damage to your computer, then it is a good idea to “outsource” the job to the experts.

These kits will usually include a microfiber, lint-free cloth with which to apply their solution. This is definitely a good idea. On top of that, the cleaning solutions will probably last a long time. You only have to use a little, tiny bit each time you clean your screen.
