With this being my first iMac I am absolutely impressed with the display screen. I am also concerned that it does smudge and collect dust easily. Of course, you can't always be completely careful with sneezing. So. what do you recommend to keep this gorgeous screen sparkling clean? For my Macbook Pro I use a product called iKlear. It does a relatively good job however you really have to rub out the fluid thoroughly or it can leave smudges behind. However, once you know how to do it correctly you get perfect results everytime. The same company has a product called HD SCREEN CLEANER that looks interesting but I am not certain if that is supposed to be used on an iMac or not. Perhsps iKleen would still be the best choice. ....but perhaps there is a better choice. Would love to hear what all of you are going to use.
