Hi guys, my used ABS M1 just arrived and I decided to wipe the keys down with some alcohol, yet something weird happened, after the alcohol dried off it's as if the alcohol was acidic and took some of the paint coating with it. Every key that made contact with the alcohol has what seems like white residue left, yet it isn't residue since I can't wipe it off with water or even scrape it off for that matter.
Would it be possible that the alcohol did indeed ruined the paint coating? If so, wouldn't this be a manufacturer defect?
