Have a good look at it first, if you see damaged components don't bother just replace it.
If all looks OK and you can see no other connectors that could have been wet flush it with metho and dry it out. Hopefully the alcohol will absorb the moisture.
You want the metho that absorbs the H2O to be flushed away so that when it dries it is only metho drying off and the moisture is gone.
Good luck.
