In my wacky, immature installation shenanigans, I got Gorilla all over a RAM socket and did not realize it an hour until drying. It's everywhere; under the socket, in the pins, and over the board where the problem spot is. With a couple of rubbing alcohol, deionized water plus dish soap sessions, paperclips, toothpicks, and a couple of acetone dabs from cotton swabs (over 50), I managed to get a critical amount off, but there is still more that is still stuck. Particularly in the pins. There is still some under the plastic, too. None of it will come loose no matter how much acetone I use. What's my next bet? I doubt Goo Gone would do better.
