Believe it or not, I breathe on my screen and use a micro-fiber cloth. I only breathe on it when there's fingerprints (from my friends) or sneeze marks on it. :D
 
I usually buy propanol at pharmacies - it's way cheaper than all the kits available (which usually contain propanol as well). As a bonus it comes in a fancy brown bottle with warning signs on it :D

I use soft cloth to apply. Propanol evaporates without leaving any stains.
 
Best method is take 2 lens cloths, keep 1 dry and dampen the other, ring it out so it's just about moist (no jokes please :p ) then go over the screen with it, and right away take the dry lens cloth and dry it off, should come up with no marks at all, thats how i clean my LCD's anyway, oh and the TV ;)

being into photography helps, ive got loads of these clothes all over the place :cool:
