I have a Dell Inspiron 8100. How do I clean the screen??
Spray some a 50/50 water/rubbing alcohol mix onto a soft cloth
and gently wipe the screen. Some electronics stores have screen cleaning wipes that will do the same thing. Never spray the screen directly.
Try the manual & read what they suggest you do. Thats the best way.
Klear Screen. Poke around on the web for the best price on cleaning kits. Very good stuff, and it won’t harm your screen’s protective coating.
