Imac Display

i was using a soft material rag like the one apple gives you...well since the display had dirty spots i decided just to use water to clean it. well the water was sticking but i was able to get it off but i noticed there were little condensation pockets at the top of the screen...they dont show while the screen is on but if i put a light to it the smudges will show up...does anybody know a way to get those little pockets to go away...plz help me they might not show on the screen while but little things like that bother me and i dont want to run into any problems in the future...if anybody has any advice let me know thank you
