Fence mold or something else...
I had a new fence put up about a six or seven weeks ago. When it was completed I noticed all of the boards have small green patches on them. I thought it was mold, but after using a pressure washer on a couple of the boards, the green patches still remain, albeit lighter in color. Is this leaching from the chemicals used to pressure treat the lumber? I want to stain the fence, but want to make sure this is not something that needs to be taken care of before hand.
Regards,
Michael

While PT wood will last longer than untreated wood, it will last even longer if a coating is maintained on it. PT should weather and dry some before any coating should be applied. 6 months before staining is the general rule but depending on application and climate conditions some PT can be stained after a few months.
I'd suggest waiting 3-6 months and then applying the stain. It might be neccesary to clean the fence at that time. After pressure washing the fence should be plenty dry enough after a couple days of sunny or windy weather.
