Algae removal/boat maintenance?

they make stuff for that its by starbrite it works pretty well for the cushions and everything if the hull has a bunch of algae on it just use muriatic acid that will eat it off the hull and just pressure wash it after wards but the starbrite stuff works great for the seats if u go to a marina they might have it if not go to advance auto parts and they usually have a special order book with starbrite stuff in it
