Was out at the boat to put on the cover and button things up. I tried some of the
On and Off on some residual places the other cleaners could not clean. It really
works. Next season should be a lot easier.

By the way, I spent some time draining my fuel lines to the outboard and inline
filter of residual gasoline. I think that is one place where gas can go bad over
the
winter and screw things up the next season.

After pulling my boat from the Root River in Racine Wisconsin, I noticed that
there
was an ugly band of black gunk at the waterline, especially at the upstream side
of
the boat when it was in the slip. A power wash got the mud off, but this band
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.
