I accidentally spill coffee my touchpad, you guys think it will siip inside? but I wiped it dry right away..

 

Really no way for us to tell for sure. A lot depends on how quickly you were able to soak it up and get dry.

 

Right away..

 

Somehow it get worst, seems like coffee getting inside touchpad, now my touchpad got sticky doesn't work properly, any recommendations as to how to get clean it, I heard about using isopropyl, but not sure if it safe, any help? Tks.

 

I had a similar incident on 3G MDX - I spilled mocha or latte, and the IDS mode button became somewhat sticky. I tried sanitizer gel, did not help. Also tried alcohol, it helped a little but did not completely remedy the issue. So I bet you will get similar result, but no harm giving it a try.

 

Douse it with this and see if it brings it back to life. You don't have much to lose at this juncture.
Wiping it down will do nothing. You need to get to where the beverage went.
