Many of you recommend so many different types of cleaners to remove the bird poop. Well, some of them worked, but not well. Some did not work at all. I don't hold that against anyone. We just have birds that produce poop with a high atomic number.Today I got rid of all the bird poop, even the industrial nuclear waste type that would not budge regardless of what I used. Untill...I used a spray bottle filled with vinegar. Yep, took the bird crap right off. It did leave a chalky film, but that is a minor inconvenience that is remedied by a good sponge bath after using the vinegar.I'm not worried that the vinegar will hurt the gel coat. I used just enough to rid the poop and then I hosed it down to dilute the vinegar.Oh... the boat smells like a House Salad! ;D
