Wipe it down lightly with distilled water nightly like the others said to season it for a week. Also do the hygrometer calibration to make sure it is accurate. Fill a water bottle cap with salt and a little bit of water, just enough to make it look like wet sand, and put the cap and your hygrometer in a ziploc bag. That will always create a relative humidity of 75%. Always used distilled water in your humidifiers and don't give up it will stop drinking water eventually and you will get it under control. I have also put a shot glass of distilled water in it with the lid closed for a week to season one.
