I've found that the best way is with a extremely soft towel (I use cotton diapers for my car and these screens) micro fiber also works but can leave a fine fiber behind. Mist the towel and then wipe while the monitor is off. If needed just increase the pressure a little but don't push hard. Flip the towel over and then lightly buff. I used a special LCD wash but I've used Windex as well with good luck, but again just like with thermal paste installation "less is more" !
