:( Not a good day.
I just cleaned the screen of my rMBP using my usual kit. A lint free microfiber cloth and my AM screen cleaning fluid.
However there must have been a small particle of something nasty either on the screen itself or on the cloth (I always keep the cloth stored away to prevent this exact issue!) the scratch that is left on the screen is admittedly tiny (~2mm) but it is there, it is bugging me and I would like to get it sorted if possible.
I've been reading up on various methods that might help but nothing definitive.
The toothpaste method that is often mentioned is unsuitable for the matte Retina display as others have reported that it left the area around where they applied the toothpaste with a glossy effect as toothpaste is actually very abrasive.
This method I'm really not sure about on a rMBP screen. There is a write up on how to do this here.
I'm wondering if anyone has tried something like Displex on a rMBP screen?
Honestly! I've read this in a few places now that due to the composition of petroleum jelly this can actually "fill" the scratches and more or less hide the fact that there is a scratch in the glass. Vaseline Online
This appears to be a product destined for use on cars but looks like it could well be used on any glass in general. ScratchPro Online
If anyone has any experience with any of the above on a Retina display or any other advice I'd love to hear it. I must admit that I'm shocked at how easy it was to scratch the screen with little to no pressure being applied.
Be careful people!!
