I have had the same problems with iklear and another product that was recommended by our electronics supply vendor for the glossy screens. Has anybody found anything that works properly on glossy screens?
I use iKlear on my glossy 13" Macbook Pro screen and it works fine. You just need to spray the iKlear onto the cloth and clean and polish the screen in small sections so you polish off the iKlear immediately. I clean my screen in quarters usually.
