After pulling my boat from the Root River in Racine Wisconsin, I noticed that

of
gunk stayed on. I had the same problem last year, and had to rub like hell with
all kinds of cleaners to get it off. Someone recommended using Tidy Bowl as a
cleaner, possibly because it contains Muratic Acid. I know that Muratic Acid is
used to clean and etch concrete, so I was wary to use it on my fiberglass hull.
Was I correct about this? Is there a better way to clean off this river junk?
I
have used Zud and other similar products, but they don't get everything off and
require a lot of elbow grease. Some of this gunk is on the bottom paint, as
well,
so I have to be careful not to dissolve that.

You might try this stuff:

Absolutely non-abrasive, and cleans far better than any thing else I
have ever used.
Chuck, have you used this stuff on water line gunk?- Hide quoted text -

If it will take off spider poop, (and it does), water line scum should
be easy. No, I have not personally used in on waer line gunk.

There's a before and after photo on the web site showing what are
reported to be the results of spraying a dirty bottomw with water,
applying the soap, letting it sit a while, and then spraying again. I
haven't done that either, but based on what I've been able to observe
above the waterline I don't doubt that they got the results the photos
illustrate.



Our spider poop must not be as strong as the NW spider poop, I can just
hose that off of my boat, even the parts I don't wax.
