I too had a "sticky" situation after spilling cola on the closed top of my laptop. None of the keys were sticking but the built in touch pad mouse keys were really bad. There was not enough room between the touch keys for a small plastic card (CVS, Kroger, or any other reward cards) so I took the tab off a paper carton (such as OTC box or any other box that has a small thin carton) and doused it with alcohol. I ran it around the spaces between the buttons of the built in mouse on the touch pad and it solved my problem in about a minute. I followed it up with a blast of canned dust remover and now it's as good as ever!! Great tip from another user!!
