    Default Washing mildew off my outboard - bleach?


    I have a 2004 Johnson 115HP 4 stroke - it is Johnson white so some mildew really shows up. The first few years I never noticed any mildew, but I think it has started to grow after I started applying some wax to restore the new engine shine. Perhaps the wax is allowing it to grow? I don't put much wax on it, I use a spray wax and am not puttin git on heavy.

    Anyway, I see some marine engine mildew wash at the store and I think the label is identifying the active ingredient as basic bleach. So was wondering if others use anything to rinse off a little surface mildew?

    I have a white boat trailer. Foaming tub and shower cleaner works real good.

    Sodium Hypochlorite is the active ingredient in bleach.

    Liquid tide soap works great.

    Simple Green is the best in my opinion...it is a VERY tough degreaser and is biodegradable...I use it in my bilige clean outs also.
    "But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
