How can I safely dry a water-damaged keyboard overnight?
Asked by

My cat knocked a cup of plain water onto my A4Tech keyboard. I don't have a spare keyboard and need to use this one by tomorrow. What's the safest way to dry it quickly, and is using a hair dryer a good idea?
Answers
Unplug the keyboard immediately, disconnect it from the computer, and turn it upside down so the water can drain. Gently shake it, wipe the outside, and leave it somewhere warm with a fan blowing across it. Do not reconnect it while there may still be moisture inside; even plain water can cause a short if the keyboard has power.

Don’t use the keyboard while it’s wet, and don’t rely on rice. Remove any easily detachable keycaps if needed to help airflow, but avoid taking the whole keyboard apart unless you’re comfortable doing so. Plain water is less troublesome than sugary drinks, but it still needs to dry completely.

The safest option is to give it at least 24–48 hours to dry, preferably with the key side facing downward and good airflow. If you absolutely need it tomorrow, inspect it carefully and only test it once you’re confident there is no dampness, but waiting longer is less risky.

VelvetOrbit3: A hair dryer can help, but only on the lowest, coolest setting and from a distance. Avoid hot air, since it can warp plastic or push moisture deeper into the keyboard.
