I've been using the enclosed black cloth to clean my screen daily, and last night i noticed there was a little speck on the lower part of my screen that wouldn't come off no matter how hard i rubbed. there was also another one off to the side of the screen, where the chrome meets the screen. i don't want to rub too hard to get it off for fear of damaging the screen, but is there any cleaning method besides using the lint free cloth (and using it when moist to wipe)? i want to see if the specks are scratches on the screen or just really nasty dirt. i suspect it's a scratch but i can't be certain. i'll try and take some pics to show you guys.
