If you want to wait 14 days thats up to you.

I prefer to go the faster way and wipe them down and let them sit for a day.
Its your humiodor do what you think is best and what your comfertable with. Do not let me or any one push you in to anything.

If you decide to wipe it down don't soak them, just dampen a clean sponge and wipe it down.
