What Did You Do To Your Boat This Week?

I'm now removing last summers below the water line brown stain from the hull. First pic shows how brown the sun side got and how the extra brite acid wash takes it off with a wipe from a scrub pad. The 2nd pic is after polishing and wax...ready for this summer.
Can you please tell me a bit more about the cleaner you used?
My boat has a ugly brown stain below the water line from 10 years of mooring without any maintenance by previous owner. I have tried all sorts of stuff, but it does not seem to touch it.

muriatic acid. then re wax. try a product called On and Off. be careful with it.
 
Don't put anti foul on it or you will have that cost every year. Not worth it if your boat spends more time on the trailer than at a dock. The stuff I use to easily clean of the staining is Alumabrite (Keith at Blackline Marine figures that is the name of it) Blackline uses it to clean gelcoat so they can do a proper colour match when doing repairs. That is how I discovered it years ago as I had my boat in for cosmetic gelcoat repairs from cannonball strikes on the hull. When I picked the boat up I noticed how perfect the hull looked as it was showing brown below the boot line. Like you I had tried many things and never got it all off and gave up thinking I would just have to live with it. I wouldn't use Musiatic acid either as the fumes from that are awful and when you are under the boat wiping the bottom of the hull you are close to your work....the stuff I use has no odor...just wear protective gloves and eyewear and use sparingly..it goes a long ways.

Awesome, thanks!
 
Anti foul paint lasts for many years, last time i had it put on it lasted for about 5 years. That was with full summers of running to Barkley sound. Had it applied at an auto body shop, some expense but If you've ever had to scrub barnacles off on a hot summer day it's no fun and hard on the hull if you let it get too bad.

Shep...30 years no foul paint and no barnacles..the trick is to pull every 30 days and bleach the bottom then rinse off. If you go longer than 30 days you will get barnacles starting to stick..and your kicker oil will be overdue for changing, your outboard greasable pivot points will be dry and your zinc will be overdue for a scrub to knock off scale. I pull every 30 days on a windy afternoon when the ramp is quiet, spray on the bleach then take it up to the local car wash to power wash the hull. Do the rest of the out of water maintenance before putting it back in...usually about a 2 hour job all total.
 
Started with a inboard with compromised transom and stringer's.

Thanks for the tip! Ive already redone the anti foul this year. For years never had to worry about the barnacles at china creek but now they're as bad as anywhere
