You should be able to buy a 16 ounces of 99% isopropyl alcohol (rubbing alcohol) for $1 or so. I fixed a laptop that a friend spilled a glass or water on by disassembling the whole thing and literally pouring 99% isopropyl alcohol on it and letting it evaporate (plus wiping down parts that looked to have had water stains on them). So with a high enough concentration of isopropyl alcohol I wouldn't even worry too much about dripping it under the keys.
So now instead of pressing zero until I get a real person I can just start yelling into the phone.
