The only problem with Spanish Cedar, my friend, is it has a tendency to release sap. This can also ruin your cigars. But don’t worry its not the end of the world. If you do get sap on the inside of your humidor, use lacquer thinner or acetone on a rag and gently wipe the inside of the humidor to remove the sap. If the problem was real bad, use very fine sand paper to remove any damaged wood. Note using sandpaper is your last resort, be very careful not to damage the wood.
