The leg and props had barnacles all over them. They pressure washed most of them off but there's still that crusty crud where they were. Anyone found any miracle product to remove all traces of them?
Yes, Elbow grease. I found you have to scrape them off. Someone should make bricks with them and build a house. It would be hurricane proof.<br /> Dead Eye
They're organic so there must be something that breaks down their composition. I've heard (rumor)certain acids will soften them to the point where a decent pressure washer will take them completely off.
I believe in the organic method before reaching for any chemical, if it's the garden,yard,house, etc. You may want to spot test with good ole vinegar or "orange" cleaner??? Both weak acids...
I've heard, not sure how true it is, that if you soak them in fresh water for a few days while they're still alive that they'll fall right off. I have no idea if it really works though.
Go to Walmart and buy Snobowl toilet bowl cleaner.Only .99 cents.Saturate the barns and let it sit for a bit.A stiff brush should do it but I have been successful with a pressurewasher the same day as it came out of the water.If no luck with that,the buy some Marykate On-Off and that should work.Charlie

I'm try in this order;<br />* Pressure washing them off (3500 psi unit).<br />* Scraping with a hard plastic scraper.<br />* Chemical remover.<br />I'm not a fan of acids all over my driveway <br />I googled and found a few manufacturers that, if it works like they say it does, are 'miracle sprays'.<br />I'll post my results next week.
I am pretty sure that muratic acid and Hydrochloric acid are one in the same.<br /><br /><br />

I used a wedge of wood... with gloves... to knock them off. It did the job, although it took a LOT of elbow, and ripped the crap out of the gloves. Just cut a couple of wedges like you would for a door wedge (4 x 4 are easier to hold) and go at it!<br /><br />Then bottom paint<br /><br />Then a boat lift
As a chemist I'd be very cautious about cleaning aluminium with muriatic acid (I presume it's an aluminium leg and prop). Sure it'll dissolve up the barnacle crud but it will eat into any exposed aluminium very quickly. If you must then, use only a very dilute solution and you sure better wash it off thoroughly. That's a beautiful boat you got so I'd stick with the elbow grease.

The leg has the factory merc coating on it... I think it's powdercoating. The props are stainless. Thank you for the warning and I'll keep that in mind.
Powder coating should protect the aluminium. Stainless will also be more resitant to the acid but will pit if left in contact with acid for a prolonged period.
Elbow grease worked on our houseboat. Knuckles were ground down almost to the bone, but we got it all off. That was the most awful experience I have ever had.
