Default cleaning lake scum from an aluminum pontoon

the tubes have some lake scum on them, Not green now, but dried on
from the winter,a nd really not that bad, but still stained from the
water lines. I'm not a fan of using muratic acid, but the stuff is
used in truck washes a lot or at least used to be. I don't know if
they're allowd to use it now or not.


anyone have any ideas on how to clean the aluminum safely? I do have a
power washer. But what ever I use, I'd like to keep it fromspraying on
the interior, unless it's safe for the vinyl apholstry.
