To properly clean a computer or laptop screen, turn off and unplug the device, remove dust with a clean microfiber cloth, and gently wipe the display without applying pressure. If necessary, use a small amount of distilled water or a screen-safe cleaning solution on the cloth, never directly on the screen, and allow the display to dry completely before turning it back on.
Power Down & Disconnect
Make sure to switch off the power on your computer to avoid the danger of electrocution. It will also permit you to see dust and grime more easily on the screen, making it easier to clear away. Furthermore, be sure to unplug the laptop or monitor before you start cleaning to be doubly sure.
Use a dry cloth to wipe off dust
As you are wiping the dust from the screen, use slow, gentle, circular motions and try not to apply excessive pressure to the screen. A lint-free, non-abrasive cloth is best to use as it reduces the risks of leaving abrasions or lines on the screen caused by finger pressure. There are several types of fabric you can use, and they are all non-abrasive. You can use a microfibre cloth, a cotton T-shirt or handkerchief, and even a sea or cotton towel will do. You should definitely avoid using paper and kitchen towels, dish towels and facial tissues.
Cleaning solution
You may need to apply a cleaning solution to the cloth to clean it properly. Never spray the cleaning solution directly onto the monitor surface, as tiny drops of water can drip out and lead to malfunction and even permanent damage. Instead, apply the solution to the cloth and make sure not to use too much. Excessive water on the screen can damage the device, so go easy on the cleaning solution.
Wipe off grime with a cloth
Work your way around the screen using small circular motions and avoid any direct pressure on the monitor screen. Be sure not to scrape or scratch at any smudges. You have to allow the cleaner to dissolve them first. If there are tough spots, repeat the process by applying another tiny amount of cleaning fluid on the cloth and repeat several times if necessary. Once you have finished, make sure to wipe off any excess moisture from the screen and corners.
Wait till the screen is dry
Make absolutely sure your monitor is completely dry before switching the power back on as it reduces the risk of moisture seeping into the mechanism thereby causing irreparable damage to the delicate internal components. Never use a hair dryer or other heating mechanisms to speed up the drying process, just let it dry naturally and don’t hurry.
Use distilled water
Tap water contains minerals that could damage your monitor screen, so it is absolutely essential to use distilled water, as it is pure and won’t damage your device. You can buy distilled water easily from many outlets such as groceries, supermarkets and petrol filling stations, and it doesn’t cost much.
Use a cleaning agent if necessary
The two most popular cleaning agents for homemade solutions are Isopropyl alcohol, and white vinegar, the two most popular and effective cleaning solitons you can use to clean a screen. They are both homemade so you may have to dilute them with a few drops of distilled water. Both are very effective at removing tough grime, however, avoid mixing the two as they tend to stick to one or the other, negating their effect. Never use cleaning agents that contain ammonia, as that can discolour your monitor. If you choose to use isopropyl alcohol, use a 50/50 mixture with distilled water, and if you decide to use vinegar, start with a 50/50 blend, and add more
FAQs
What is the safest way to clean a computer or laptop screen?
The safest approach is to turn off and unplug the device, then gently remove dust and fingerprints with a clean, lint-free microfiber cloth. For stubborn marks, slightly dampen the cloth with distilled water or a manufacturer-approved screen cleaner and avoid applying pressure to the display.
Can you use water to clean a laptop or computer screen?
Yes, a small amount of distilled water can be used to dampen a microfiber cloth when cleaning a screen. Do not pour or spray water directly onto the display, and avoid excessive moisture that could enter the device and cause damage.
Can you use alcohol or vinegar to clean a screen?
It depends on the screen manufacturer’s instructions and the type of display coating. Some displays can be damaged by alcohol, vinegar, ammonia, or other household cleaning products, so a screen-safe cleaner recommended by the manufacturer is generally the safer choice.
What should you never use to clean a monitor screen?
Avoid abrasive materials such as paper towels, tissues, rough cloths, and household scrubbers because they can scratch or damage the display surface. You should also avoid spraying liquid directly onto the screen and using cleaners containing ammonia unless the manufacturer specifically states that they are safe for your display.
How often should you clean a computer or laptop screen?
A computer or laptop screen should be cleaned whenever visible dust, fingerprints, or smudges begin to affect visibility. For most users, gently dusting the display regularly and performing a deeper clean when needed is sufficient; frequent aggressive cleaning is unnecessary and may increase the risk of damaging the screen coating.
