I'm sorry Derek, but I'll just offer this up one more time:
Moisture that comes in contact with wood causes wood to swell, which in turn can cause the wood to splinter. The splintering might be small enough for you to not notice at first, but could potentially damage that prized cigar while you're in there rearranging your stash. (It has happened, and will continue to happen)
Humidity levels or temperatures can cause swelling and splintering if they change suddenly. Perhaps the easiest comparison to understand is that of your cigar itself. If you want to revive a drying cigar, you never just throw it in a 70% RH humidor, right? And what happens when you light up that stick on an overly dry day? (search for exploding wrappers, you'll see)
You should always gradually increase or decrease temperatures and humidity levels. And this is only talking about splintering. What do you wipe that water on with? Know that you're leaving little bits of sponge on everything you wipe down. You might not notice it, but it's there. You used a rag? Well just how clean was it? Then, don't forget, putting straight water on wood in a sealed environment is asking for mold. Just because one person can walk blindfolded through traffic without getting hit didn't mean you can to. Eventually someone is bound to get hit.
Be patient. Take your time. Put a few dishes of distilled water in there. Let the environment settle by naturally absorbing moisture through water vapor. You need to let it sit for a few days anyway to stabilize. Why push your luck?
Or, wipe it down. Your choice.
I'm just trying to watch out for best interests.
