Isay open it up to see if any water hot inside the cabinet. Don't connect power to it until you are certain it's dry. If wet inside at all, take a hair dryer, not a heat gun, and dry it out. If you see a white powdery-stains on the circuit board, that's corrosion
from the water. It doesn't mean it's ruined. Just scrub it off with an old tooth brush, either dry or dipped in some isopropyl alcohol. I doubt you have any issues, but a little water can cause a short. So can enough corrosion
. The corrosion can deteriorate certain metals and eventually cause damage. That's why it's good to gently clean the board if you see the white stuff. I'm not familiar with your rig, but many manufacturers spray a coating on the boards to protect against. Moisture. It isn't waterproof, but helps with condensation
Some people swear by things like putting a wet cellphone in a bag full of rice so the rice will absorb the water. The damage will happen before the water is absorbed. I was kind of expecting some to suggest that dump rice into chassis and leave if for a week.
Good luck with it, and it sounds pretty minor and not much water. If you aren't certain, just bring it to a repair shop and have it looked at by someone who can recognize the problems.
