Questions about Monitor cleaning...

Hello:

I just successfully installed my first distro and while I was hooking up a used monitor, I noticed that the screen needed some maintenance. Now, I realize that isn't a Linux-related question but: It's a Samsung Flat-Screen CRT monitor. As most of you are aware, flat-screens are made of different material than the glass used in screens of older CRT's. Thus, the cleaning methods must be different because I tried using a damp cloth to wipe some spots and/or grease-stype stains - and the marks got worse. Also, there were hints of rainbowish-colored streaking. Can anyone of you help me out?
Thanks, Neo_Tux

I use fish tank cleaner on mine b/c it has no anonia in it.

I use the method from my monitor's manual: first cloth+water (only) then, when it's still wet, another cloth to make the monitor dry.
