Boiling water is good for tea and having babies, you only want to use Distilled Water, not boiled or purified or from the Red Sea.
Also, and peoples opinions seem to vary on this, some very wise people told me you shouldn't wipe down the interior because it can cause the wood to warp, sponge with distilled water on a plate of some kind and check the sponge after 24 hours to see if you need to dampen it again.
Really though, hit up the store and get a gallon of distilled water and keep it on the side somewhere for use with your humidors.
Best of luck
