Liquid / Water Spills

keyboard suffered a small kitten-induced water spill. I dried it out, but predictably, it's now behaving a bit strangely. Most of the keys are fine, but a few are now operating in pairs, e.g. if you hit either the Y or the U key, you'll get the same output which is 'YU'. There are six pairs of keys that are behaving like this: HJ, NM, YU, 67, ;/, and space'.
