For this method, the first step is to again power down your computer so that you can easily see all the debris on its screen AND so that you don’t inadvertently cause damage or burnout to the pixels. Never apply the paper towel to the actual screen of your computer. Very carefully, lightly spray a paper towel with the cleaner (don’t soak it!) and run it along the frame and base. The only areas of your monitor that can withstand multi-purpose cleaners are the frame and base of your computer.
