Wipe the Inside of the Humidor With Distilled Water
Seasoning a Humidor
To season a humidor, all you need is some distilled water, a clean unscented sponge or cloth, and some patience - at least for a few days. IMPORTANT - Do not use tap water in place of distilled water.
Start by dampening a clean sponge or cloth with distilled water, then wipe down all the cedar wood inside of the humidor, including the lid and any trays.
