It's a long story why this happened, but my boat ended up sitting in the water for about a month. That was long enough for it to get really dirty and there's algae growing on it. <BR> <BR>Can I use a pressure washer to get it clean, or would that risk damage to the gel coat?

Scrub it off while the boats still in the water if it's not too late. Once that stuff dries it's hell to get off. The pressure washer won't hurt it that I'm aware of. <BR> <BR>(Message edited by wake_upppp on January 19, 2010)

No damage at all, but dont pull it out of the water until your ready to wash it. When that chit dries, it's hell to get off.

Starbrite hull cleaner. It'll come right off.

Ditto on Starbrite. I've used it on my 2006 210 regularly and have had no damage and good results,

I have not used starbrite but have used a product called "on off"(designed for boats) for the exact application you're talking about. With that product we didn't even need a pressure washer. Just a garden hose to wash it off. Hull looks brand new.

You'll want to use hull cleaner. Starbrite hull cleaner or toilet bowl cleaner - should come right off then.

starbrite works wonders.. my boat sat in a dock in red muddy water for 2 weeks. scrubbed and scrubbed wit hsoap and nothing. saw the starbrite at wallyworld for 6 bucks and tried it...WOW just wipe on with a sponge and wash off. Be sure to apply a coat of wax when your done.

FSR is unbelievable, too. (Fiberglass Stain Remover) Just know that it will strip any and all wax.

Like Dwight said the on/off product works great just make sure you wear gloves and do it outside.

Yea, any hull cleaner is toxic stuff. So wear rubber gloves &amp; rinse everything off really good... your boat, your trailer, yourSELF.

THANKS for the GREAT advice on products and safety steps and waxing the hull afterward. I hadn't thought about that. <BR> <BR>The hull already is out of the water, and I know how hard it can be to get clean. I'm going to get hull cleaner and give it a try. If that doesn't work, I'll have the pressure washer standing by.

Just a thought. Once its on the trailer you wont be able to clean the hull where it sits on the trailer bunks...you will have some cool green stripes though! <img src="http://www.wakeworld.com/MB/Discus/clipart/crazy.gif" border=0>

Toilet bowl cleaner does the trick. I used it on my boat when it was neglected for a few weeks.
