You never want to rub down the inside of a humidor with distilled water.

If your humidity is too high then remove the humidification device until it gets back down to 65 percent. If when you put it back in and it goes up again, leave it out. I have had humidors in the past where I kept the humidifiaction device out for months at a time. Your cigars hold humidity, it could take months for them to lose their excess moisture.
