The first step is to read and consult your humidor's manual, should it come with one. There are several methods to cleaning a humidor; you may pick any of the ones listed below.
- Remove cigars before cleaning and store them in an airtight container during the cleaning.
- Dampen a clean, lint-free, soft cloth or sponge in distilled water. The fabric mustn't be dripping or soaked, as you do not want to drip or spill water within the humidor. Always avoid tap water, as it can leave stains and mineral deposits. Gently wipe down the humidor with a cloth dampened with distilled water.
