What is that mess on deck?
This may be slightly off the thread, but does any other slipholders in the Downtown Shoreline Marina in Long Beach CA notice oily spots on the decks, dodgers, canvas, everything. It started about two months ago, I think. Spots the size of quarters to silver dollars, with an oily base that beads water and resists cleaning. I resorted to liquid laundry detergent used straight, and even that doesn't always get it all. I think it might be the dozens of helicopters that fly overhead emitting unburned fuel out the exhaust. Anyone find anything similar?
