Coverage
16–32 washes per 32 oz concentrate
Washing a 24 ft boat (~528 sq ft) uses about 2 oz per wash — one 32 oz bottle of Sea Scrub covers roughly 16 washes of your boat.
Rough estimate from typical topside area — real use varies with prep, surface, and conditions.
Hose down the boat to knock off loose salt and grit before you wash.
Mix 1–2 oz of Sea Scrub per 2.5 gallons of water in a wash bucket, or load 1–2 oz into a foam cannon for maximum cling.
Work in sections with a soft wash mitt, from the top of the boat down to the waterline.
Rinse thoroughly and dry with a clean microfiber to prevent water spots.
A high-foaming, pH-neutral concentrate that dissolves salt, mineral deposits, and grime — from fish blood to party spills — while staying gentle on your wax and ceramic coating.

“The foam actually stays put”
I keep mine in a wet slip and rinse the salt off every Sunday. Most soaps slide off the hull before you even pick up a brush, this stuff hangs on long enough to actually work. Salt film came off without me leaning on it. Didn't touch the ceramic coating either, which was the thing I was worried about.
“One capful. Seriously.”
honestly didn't believe the label but one capful really does make a whole bucket of suds. Washed the pontoon four times since it showed up and the bottle's still basically full
“Good soap, dumb cap”
The soap is great, rinses clean, no spots if you dry it like you're supposed to. But whoever designed that little measuring cap has never stood on a dock with wet hands. Knocked a star for that. I'd still buy it again.
“Wax survived the test”
Waxed the hull at commissioning in April and was paranoid about washing it off. Five or six washes later the water still beads up. That's really all I needed to know.
“Handles the brackish funk”
Brackish water down here leaves a brown film on everything by February. This takes it off in one pass and it doesn't smell like a chemistry set, which my wife appreciates since I track the smell into the truck.
“Slick suds, no new scratches”
I put swirl marks all over my last boat using cheap soap and a dirty mitt, so this is the thing I watch for now. The suds are slick enough that the mitt just glides. No new scratches in the gelcoat so far this season.
“Just buy it”
Good suds, rinses fast, skiff looks right.
“Brother-in-law wouldn't shut up about it”
We splash the week after Memorial Day up here and the hull always comes out of storage with a year of dust and bird mess on it. I usually just grab the blue stuff from West Marine and honestly it does fine. Tried this because my brother-in-law would not stop talking about it at Easter. It foams way more and the hull rinsed cleaner, I'll give him that. Only knock is my bottle showed up with the cap a little loose and some had leaked into the bag. Not enough to matter, but tighten the caps guys.
No. Sea Scrub is pH-neutral, so it cleans without stripping wax, sealant, or ceramic coatings like Aqua Armor. It's safe to use as your regular maintenance wash.
It's a super-powered concentrate. Mix 1–2 oz per 2.5 gallons of water in a wash bucket, or add 1–2 oz to a foam cannon with water. A little goes a long way.
Yes — that's exactly what it's made for. Add 1–2 oz to your foam cannon with water for a thick, clinging layer that lifts grime with less scrubbing.
