Wet can be used to describe being dowsed in liquids such as beer, milk, juice, urine etc. All of these, however, are water-based. Can wet be used for a liquid that has no water? Can you be wet by mercury? Or liquid nitrogen?
I know I wouldn't use it for mercury, but that may be because mercury would not actually stick to anything it was splashed on so it wouldn't even look wet. I could live with drenched, dowsed, or immersed but wet? Does wet really imply water or is it just that we tend to get splashed by water-based liquids and so the word is most often associated with water?
This definition states
consisting of, containing, covered with, or soaked with liquid (as water)
What do you think, would anyone use wet for something completely unrelated to water?
