Don't be so quick to blame the cleaning method. I've never used anything but water and got the same damaged screen coating.
it's still inexcusable from apple, but don't be surprised if rubbing tap water on your glossy screen screws it up.

I used tap water to remove e-cigarette refill fluid (an oily substance) that I spilled on a non-Apple glossy screen, using a dirty rag. Unsurprisingly the screen is still absolutely perfect and handled the highly corrosive water just fine.
Apple's bullshit is getting to you.
