macbook pro anti glare coating problem with stains
Hello, I bought an used Macbook Pro 2015 retina display a month ago,
it had some little stains on the screen, which were anti glare coating stains as I later found out,
these stains seem to appear on other places of the screen too, I don't remember noticing them when I was buying it...
The reason has to be some kind of stains from fingers which stay on the keyboard and then the glass gets damaged...
So my question is how do I clean the keyboard to avoid these stains and....
the stains that are on the screan right now, are those going to get bigger even if I clean the keyboard from now on ?
Thank You
