If you haven't already taken your keyboard apart, don't. Most well built keyboards have a
membrane that covers the switches under the keys (cheapies might not). Fill a spray bottle
with alchohol and with the keyboard upside down, spay the sticky keys generously
with alchohol. Then use the cool hairdryer to dry it out. (Shake the keyboard
gently to remove any alchohol that might be inside the keycaps.) The keycaps might
also be removable. If they are, that is the best alternative.
