    So you're looking for a good cleaner for the outside of the hull?

    yea something that will really get it off. i have tried sulferic acid and sno-bowl a few times but there is still stains on the bottom. im considering wet sanding with some super fine sand paper then buff it all out again.

    Long ago, before buying a lift, my parents left their boat in a lake that had terrible algea growth. I was the one in charge of cleaning the bottom every month or two. It was a nasty experience, but I've never seen Muratic Acid unable to take that stuff off. Sometimes it required a good scrubbing, but that stuff ate anything... including skin!

    I believe the marina where my boat is stored, they use the same muratic acid to clean the bottom of my boat off. It went in dirty and came out sparkling... LOL.

    Cost me $50, but it was worth the cash.

    I personally would not touch the stuff. I hate handling hazardous chemicals. So thats why I leave that up to them. They know what they are doing...lol.

    my problem is most of it is on the underside so in order to get down there to clean it i am very likely to get it on me and that stuff burns! not to mention breathing it is even worse. i have some super fine sandpaper discs that i have used for body work that i am considering trying. i may just try rubbing compound and the high speed polisher first.
