For the first time in 6 years, when I went down to the rig in it's storage bay to start getting ready for a trip next week, I found white powdery stuff that I think is mildew all over the wooden surfaces in the kitchen and living room areas. Did not seem to be any in the bath or bedroom. The trailer has been sitting idle since mid August, but has had some much longer periods of inactivity with nothing like this happening. It is under a solid roof, out of the weather when in storage. What should I look for as a cause, and what should I do for prevention once I get it cleaned up??
