Hi Bud, I think you will find that the customer, had added some kind of humidifier treatment, that made the moisture corrosive. Dampp-Chaser in their literature has warned about adding chemicals to the water. If they have added anything, check the label and see if it is corrosive. Their e-mail is <damppchaser@circle.net>, I am sure they would want to know, so they can make the warning more prominent. Regards, John M.
