2. Use a dry, soft cloth -- the kind you would use to clean your eyeglasses -- and very gently wipe the screen. If this doesn't remove the oil or dirt, do not press down harder and try to remove the dirt. Pressing down on the screen will cause the pixels to burn out. Rather, proceed to the next step.
3. Make a solution of equal parts water and vinegar. Dampen a cloth in the solution and gently wipe the screen. Again, rubbing and scrubbing will damage the screen.
Here are some important tips you should know.
• Avoid using paper towels, toilet paper or something like your shirt to wipe the screen, as these may scratch or damage the screen.
• Do not use products that contain ammonia, ethyl alcohol, acetone or ethyl chloride. These chemicals can cause the screen to turn yellow.
• Never spray liquid directly on the screen as it can run inside the monitor and cause damage
