A friend accidentally dumped her coke into the keyboard of her computer, and asked me how she could clean it since the keys were sticking. I suggested acetone, which cleans and then evaporates. She said ok, and promptly dumped in a whole bottle of fingernail polish remover! I was thinking brake parts cleaner. Anyway, she got mad because her keys stopped sticking but didn't work anymore! After it dried up, though, it worked just fine.
Although I'm not suggesting the same thing here! I would probably try an electronic parts cleaner.
