This is a 2015 model.
The "staingate" name is odd, it's definitely not staining, the laminate just wipes right off with little effort.
I use a microfiber cloth to remove dust from the MacBook Pro display. Never have used a chemical once, there is no need if you are dusting a display.
I'd take a video and show you how you can scrape off the laminate with quite literally anything, but I have nothing to prove to you. Besides, as another commenter has pointed out, Apple is apparently replacing these screens if you can handle to be away from your work machine for the repair time.
It's build quality.
I bought it brand new knowing about Staingate and purposefully treated the screen with kid gloves, yet here we are.
