    This product is simple amazing how well it cleans my boat. The lakes we go to in our area leave a heavy rust colored film on boats. Your product simply washes this film off with little effort. I have tried numerous other products with little to no success.

    Pros:
    • It’s spotless after it dries.
    Cons:
    This product really does work. I use it on my waverunners. I spray some water on the wave runner, then I spray the bio clean on it, I rub it in with a wet sponge and then rinse and then let it dry I don’t have to dry it or anything. It’s spotless after it dries.

    Awesome Product

    Pros:
    • Product works as advertised
    Cons:
    • Pricey but you get what you pay for
    Used this product many times before. Virtually labor free. I do brush it off with a wet soft bristle brush and the boat turns white again. It removes the yellow scum line that I get on my boat from it sitting in the water over several weekends. And it is useful on the marina's black hand prints (why can't they wash or wear gloves) on the boat as they take it to dry storage. I have used other Bio-Kleen products and would recommend each one.

    Pros:
    • Ease of use
    • environmentally friendly

    • Spray bottles could be better
    Minimal scrubbing required for removal of redline / mudline / pollen line. Spray on, let sit a minute, soft brush then rinse.
    So glad I found this product!! Try it, you'll like it.
