First Warrior:You can also get it dry and LIGHTLY scuff sand it with 220 (fine) sandpaper. Wipe up the dust.
bigharpoon:If that discoloration is centered around a small nail (probably a brad or pin) then I wouldn't worry about it. That discoloration is not the same as mold which will affect your cigars.
