Does anyone know of any special cleaners that will remove the film from the hull of my boat. My boat was nice and clean when the season started, but now after I have sailed in the Baltimore Harbor a few times my boat has a brownish film along the water line. I have tried to clean it, but nothing seems to help. I have tried power washing, Simply Green, Acetone, Componding, Black Steak Remover & CLR. Is there something I'm missing?? I'm beginning to think my only solution is to wet sand the hull. Any ideas would be greatly appreciated.
