On the subject of wetting the cedar lining, I've done it that way on two of mine, but on another I used a method suggested to me by someone I've come to regard as a bit of a humidor wizard ... he said wetting the interior was a mistake and that the best way to season thw wood was to place a good sized open container of distilled water inside the 'dor, close the lid and leave it for several days ... test it after that with a hygrometer to learn when it had reached 70% ... and voila!, ready to go.
It does take a couple of days longer to do it that way, but the unit I seasoned that way is my best 'dor ... coincidence? maybe, but maybe not, I dunno ... all I can say is that based on that experience, I'd not wipe the wood with water again.
