How to Clean a Laptop Screen with Household Products(4)
2.Do not use paper towels, they are made with wood fiber and can scratch the LCD screen.
3.Avoid using products such as Windex because these contain ammonia and it can degrade the LCD panel.
4.Shut down your laptop, unplug it from the power adapter, and remove the battery before cleaning it or you risk damaging the pixels in the LCD display.
5.If in doubt, test a small area of screen first.
6.Using a lint-free microfiber cloth is best, an "old T-shirt" or other soft cloth can introduce dust and lint which may be detrimental to the computer itself.
7.Don't use isopropyl alcohol above 90% as it will contain some acetone which deteriorates plastic.
