Cleaning screens
Okay, it's a little weird.
I have a refurb Dell P991 (IIRC) monitor (19", flat trinitron). It has a weird oily looking dirt on it which won't come off. I note every other monitor like it I've seen (my local college has dozens) also has it. It's largely only visible when the monitor's powered down. It smears around when you try and clean it. What doesn't work: -Dish soap (tiny bit in water) -Alcohol diluted -Eyeglass cleaner What else is reccomended? |

It's probably what's left of the anti-reflection coating; I've seen similar things where people have used solvents to clean the screen and it dissolves whatever was used to stick this coating on, leaving rainbow patterns and strange smears on the screen. As to what will remove these deposits.. I've no idea. Things that don't work include: Windex-type window cleaner, Electrolube solvent cleaner(s), Inkjet nozzle cleaner (acetone?) and 'breathing on it and giving it a good polish'. |

A product called Goof-Off (mostly xylene) is about the best general
purpose solvent I know -- better than acetone. |

Lay it on it's back, dampen a paper towel with kerosene and leave it flat on there for a while. Keep it off the plastic if you can. -- N |

People must have been putting their fingers on the screen surface, thus
damaging the coating. When people come over to my place, or where I work, I warn them to not touch the screen, unless they are interested in replacing it for me. I have a sign on the top of my monitors, "NEVER Touch The Screen Surface, Or Your Knuckles Will Be Broken". -- Jerry G. ===== "Jack Zeal" wrote in message ... Okay, it's a little weird.

I've had a few similar monitors where I was able to clean it off but I had to scrub the heck out of it with some of those monitor cleaning wet wipes. |
