I know that sounds like a stupid ass question. I have the Logitech wireless mx keys. I wiped the keyboard down so the surface of the keys aren’t sticky, just hard to press down and some have a spasm.
Since a whole ass thing of coffee did not short it, it gives some credibility that it is water resistant. Can I just dump water on it to help it?
You need to unplug it, take the keys off, and wipe everything down with a little bit of isopropyl alcohol. Do NOT dump more water on it. That could short things more and drive coffee grounds and water deeper into the inside of the keyboard than they already are. Keep it unplugged to dry for a day or so.
