Hello, As most mac users I am very careful with my equipment (a behaviour that most often is bordering on the unhealthy) and especially so when cleaning the screen of my MBA. As we know the screen gets smudgy easily and in my case it collects a lot of dust. To clean it I only use a microfiber cloth (which I regularly change) and dampen it slightly if necessary without applying too much pressure. Despite this (following Apples recommendations) I have noticed several fine lines/scratches that are visible when sunlight is reflected from the side of the screen. One needs to tilt the screen a bit for them to become visible. Now, I am wondering if this is something other people have experienced and what the cause could be? Is it that I am damaging the anti-glare coating on the screen (the scratches dont seem to be very deep at all)? My main concern is that regular cleaning will eventually damage the screen significantly. I have tried a protective screen cover (Moshi iVisor) but dont like the colours when its on. Any and all feedback on this is greatly appreciated! Many thanks.
