What is the best way to clean a matte LCD?
I dropped a bike helmet on the screen while it was open. Don't ask.
I used some iKlear solution and a microfiber cloth after the incident and a lot of the marks came away as they were just plastic rubbings. But there are a few marks left and I'm pretty sure I've actually truly scratched the screen but I want to be sure before I take it to the genius bar and cross my fingers (or get laughed out).
So what is the absolute best way to really truly clean this matte display and find out if what I've done is physical or cosmetic?
I'm assuming that's my only course of action, but I'm all ears if someone has a better idea.
