Coke (and other cola drinks heavy with citric acid) were well known keyboard and mobile phone killers. I know thta if I was asked about recovering a mobile phone with coke spilled on it I always told the owner that it was almost certainly a dead loss. the acid and the sugar was always a good combination to destroy electronics.
I used to work in car dealerships doing their IT in the early 00's. It took a touch machine to last more than a year in a garage workshop. They weren't the toughened deviecs seen now just basic PCs with 21" trinitron monitors to display repair manuals.
