Pontoons can become damaged and discolored as they sit in the various types of water. The water components play a major role in this discoloration, but there are many products available to restore the shine and make them look new again.

Additional Tips and Advice

    My pontoons have never been cleaned. Layers of hard lime-like rock has built up. What is the best cleaner or solution? I have tried cleaners from boat companies and it takes hours to clean a very small area. Any suggestions?
    Thanks.

    Have just used a product called Foam-Brite by Nu-Calgon that is an a/c coil cleaner. This is a non-acid product and it’s biodegradable.
    Cleaned the Grand River scum and crud of the ‘toons and left them shiny new.
    Used a hand sprayer and electric power washer. It took less than an hour and it’s so safe, it never even hurt the grass.
