We recently purchased a boat that had been sitting for some time. I had small black spots all over the boat that look like bird droppings, tree sap or pine tar. On the smooth deck we could scrape them off but with the boat covered in the small specs was taking hours. On the deck it was impossible to get off. We tried all of the following:
Goo Gone, Soft scrub, The works (this was too caustics to work with considering the amount of cleaning we had to do), rubbing alcohol, bar keepers friend, simple green, Poop off (yes there is a bird dropping product called this) and on and on. At the marina a guy stopped by and gave us Marine Spray Nine he bought at wall mart. The rubbing alcohol worked to some extent but we smelled like a hospital. The best was MARINE SPRAY NINE.
Doing a quick search I found a few post in 2000 that referenced the product but no recent post.
It cut through the black spots, turned them a tanic yellow and with a hose, wash away about 80%-90%. Second application followed up by soft scrub and another spay down and we have a white clean deck. It also clean mildew and mold. No a great smelling product but th smell does not linger.
I am not a big product endorser as there are so many varibles that make a product work for one and not for another but, after many hours of trying everything else finding something that worked for us was a real relief and the cheapest, second only to the rubbing alcohol.
Now we are off cleaning all the fiberglass in sight and keep a bottle on the boat. It even worked on a red wine stain from that dired over night.
