I'm sure this scenario has happened to quite a few people on here, but since I'm a bit OCD I'll ask for your advice. I have my 15" retina MBP sitting on my desk plugged into an external display. I noticed this morning that there was a small spot of dried tea on the aluminum top cover. Apparently my coffee mug must've been dripping a bit as I sat down for work. The spot quickly came up using a soft cloth and iKlear. No mark or stain underneath. Is it possible that a spot of hot tea on the lid could damage the display inside?
