Despite lecturing people about how they should keep their drinks away from their laptops, of course I spilled some soda onto my 2016 tMBP - it's been a few weeks and it's working fine, but my alt-key has gotten... sticky. Does anyone know the best course of action and the possible cost to get it cleaned up? I'm hoping it'll be a bit less than a complete logic-board replacement, since it's working fine (except for that one sticky key).
