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'.
