how can I verbs a smudge stale of my flat peak monitor?

Answer:

First try a soft dry cloth, if in attendance is still a smudge, dampen one corner and try again, drying after, DO NOT use cleaners.
There’s a difference between a “flat screen” monitor and a “flat panel monitor.” If my assumptions re correct, you hold a traditional CRT monitor with a cup screen; if so you can use a cleaner, I used to use it on mine adjectives the time. However, if you have a flat panel, you should acquire special LCD wipes or a cleaning utensils which are designed for the flat panel screen surfaces.
If this is an LCD eyeshade, I use http://www.pixelclean.com . Don't use anything containing alcohol or ammonia. These harsh solvents could vandalize the film on the outter covering of the LCD screen. Also, use a mirco fiber cloth, not a quality newspaper towel.



If it's a CRT screen, any cup cleaner will work. LCD screens aren't made of cup, thus you should not use a glass cleaner on it.



Good luck.
