    Believe it or not, Shout stain remover for clothing works great. I was cleaning the hull of Waverunner one day and had run out of hull cleaner and thought "I'll give it a try" Tough on stains yet easy on fabric so must be OK for my fiberglass and gel coat, right? Worked great! Light scrub and was clean as a whistle.

    +1 on this (cheap and easy) but don't breath it either when spraying. It will strip the polish/wax so reapply a coat of protection when done.

    I used the on/off this year and it worked great. i heard not to spill it on a galvanized trailer but mine is painted. i sprayed the trailer to get it wet and got quite a bit of the on/off on the painted trailer and no issues with it

    The foaming Barkeepers Freind works pretty good and is much less caustic. I spray on the whole boat , wait, and then use a scrub brush to get the last bit off. Then hose off. It's not spray and wash like the on and off, but it works as it has oxylic acid in it.
