Balsamic vinegar in keyboard - isopropanol best way forward?

Hi!

Series 9 NP900X4D

Solution?
I am thinking I would flip up the keys with a small screwdriver and try to clean with isopropanol. Does that sound like a good idea, or does anyone have another suggestion? I found this video that could be of use.

Problem:
So I flipped over a bottle of balsamic vinegar at dinner and of course it fell over the keyboard and left a healthy pool of sticky vinegar flow down into and around the Backspace and Enter keys. I shut the computer down and left it to dry for 48 hours and while several keys had become slow/gluey afterwards they worked and the computer showed no malfunction. That was four weeks ago.

Now the computer still works fine but the Backspace and Enter keys are becoming more gluey and sticky than ever. To the point of almost being unusable, since they have trouble to rise after being depressed.

 

Just take it apart and carefully clean everything with isopropyl alcohol using cotton swabs and cotton pads. If you just dump it in there it might dissolve the dried substance but it will just end up flowing elsewhere most likely. If you're worried try the alcohol in a discrete area first, though I've never seen it damage anything before.

 

Thanks!
I began taking it apart but balked at all the small screws and devices and cables I had to remove in order to get to the keyboard and - GULP! - reattach afterwards. I did not feel up to the challenge so I actually proceeded very carefully from above, lipping away the caps and scissor hinges, bathing them in washing up liquid and rinsing, and swabbing carefully where they sat on the keyboard. Yikes, that stuff was sticky and gluey! But I managed and I can see no side-effects yet. Hope I did not wreck anything. When I get a new laptop I'll make an attempt disassembling this one to clean it thoroughly, for the fun of it. Thanks again!
