Gently? Try no rubbing at all. Just put a paste of it on there and let the
acid do the work. If you rub it you'll just be putting more scratches into
the gelcoat. Making it easier for the gunk to attach to it again next
season.

Your best bet is to stay on top of this during the season. Just use a
soft/medium brush on it. Shur-hold makes an attachment with bend in it that
makes this less hassle. If you're in the water you can use one of those
suction cup handles to give you a hand hold to really get a good scrub.

I use a brush with a liquid oxalic acid solution. Removes those stains
for me. The most annoying stains I seem to encounter on the hull are
those left behind by the tannin in the water.

I've always used Soft Scrub - non bleach, non scented.

Works and not a lot of "elbow grease".

Which is still an abrasive and will not help your gelcoat.

Really?

Hmmmm - well, no.

Here's a image of the interior of the boat which gets all kinds of
crud, blood and stains - see any deterioration of the gel coat?

We have a fiberglass bath/shower and it's cleaned with Soft Scrub all
the time - no scratches there either.

It does work and work well.

I was a little harsh on that reply - my apology. A little tired
today.

I've used it for a long time and never had a problem. I'll admit it
did hit the boat with Finesse-it II three years ago, but I still use
Soft Scrub with no swirls or fine little scratches.

On and Off is quicker and requires almost no rubbing. It is much
easier on fiberglass than Soft Scrub. Wear eye protection and old
clothes.

Sno Bowl works just as well and is cheaper, same ingredients
basically.

I've never had a problem with Soft Scrub - ever.

And the finish on my boat is damn near perfect.
