Cleaning that nasty hull..

[Dash Four]

We took the Parker out last fall, and did not power wash the hull.
Now we have a concrete mess!

Doing research I have found references, to all sorts of techniques
including the use of muratic acid to get rid of the barnicles and stuff.

Has anyone actually used it, or do you have any other suggestions?

Put it back in the water for a few hours. Everything except the barnacles will soften up so it can be powerwashed off. Then just scrape the barnacles.

i'll second GW204 except you will need to leave the boat in at least overnite for the crud to really loosen up. Then just powerwash it.

Thanks for the help....

Muratic acid works for me and is a cheap bottom cleaner. I spray it on with a pump sprayer ....held maybe 12 inches from the hull...and after about 30 seconds hose it off. A word of caution...don't get it on aluminum, wear gogles and avoid inhaling the mist.

Mary kate on and off gel. It.s gooet and you paint it on the hull with a paintbrush (natural bristle). Let it sit for a while then just spray it off. Wear gloves and don't get it on you or the trailer. Works like magic.
