Wrap the hygrometer in the towel. Set it aside for 30 minutes. Remove the hygrometer in the towel and calibrate it so it reads 95 to 97%. Each hygrometer will be calibrated differently. Refer to your manufacturer’s instructions to figure out how to calibrate yours. If your hygrometer already reads 95 to 97% when you remove it from the towel, it is ready to use. You do not need to calibrate it.
If there is any old tobacco or debris in your humidor, spray the inside of the humidor with compressed air. Wipe down the interior of the humidor with a damp rag.
Keep the humidifier face down. Leave it submerged for 2 to 3 minutes. Wipe off any excess water with a paper towel when you remove the humidor. Make sure you use distilled water. Tap water can damage a humidor.
Once the hygrometer and humidifier are in place, close the humidor. Set the humidor aside somewhere where it will not be disturbed. Leave it closed for 12 to 24 hours.
Once you’re done, the humidity level should be between 65% and 75%. It may be slightly higher right after you complete the process. Give the moisture levels a few minutes to go down. Your humidor may not be between 65% and 75% after repeating the process a second time. In this case, you’ll need to repeat the process one more time.
In the event the humidity has dropped, you will have to repeat the preparation process. You would remoisten the humidor the same way you initially prepared it. Make sure to use distilled water when you repeat the process. This is just as important the second time around as it was the first. Tap water can harm the humidor.
A drawer is a good place to store a humidor. If you have children or animals, keep the humidor out of their reach.
