First, soft cloth with water This way is used only when there is only some dusty on the LCD screen. It is very easy to get the dusty out of the screen. You only need to use a wet and soft cloth to wipe the dirty LCD surface gently. But please pay great attention to two points. One is to remember to use soft cloth. Otherwise there will be many scratches on the screen after you clean the screen if you use some rough cloth. The other is to remember not to make the cloth too wet and don't let water in the gap of the screen margin, because water will make your laptop screen stop working.
Second, special cleaner If there are some oil and dirty fingerprints on the LCD panel, you will need some special LCD cleaner to clear them and keep your LCD screen panel beautiful. You can buy the special cleaner in any laptop stores or in some electronic markets. But please do not use some unknown detergents and alcohol to clean the dirty things on the screen, because they may contain some corrosive chemical composition.
Although special cleaner is relatively expensive, it can be used for a long time after you buy one. We can use a little of it to clean the LCD screen and make the screen very clear.
Please pay attention to the way of cleaning the laptop LCD screen. Then you can keep your screen beautiful all the time.
