After being "on the hard" for five weeks, everything looked okay on my deck. After getting back to homeport, noticed that after a night's dew, deck is almost completely stained with red, blue and green. I have scrubbed it twice until clean and white again. However, the discoloration shows up again in the mornings after a heavy dew. Could this somehow be related to people grinding their bottom paint off when my boat was in the yard. Could this be copper? What can I do to get rid of it? Help!!! By the way, after using compound, still had the problem.
