So now I feel like an idiot. In an attempt to clean the screen of my 15" rMBP (2013), I got a large drop of iClear cleaner on the edge of either the F8 or F9 key. I think I soaked it up before much got into the case, and the keys seem to be working fine, but I turned the machine off and am hoping it dries out OK. In looking at the teardowns, it seems that there is a some sort of membrane behind the keyboard, so any liquid that got under the key likely would not have made its way to any of the parts underneath. Can someone (through hard experience or otherwise) confirm that? Many thanks.
