Boat Buddy Marine Surface Cleaner is sold as a second-stage product in an eight-stage cleaning system. It’s a similar formulation to Grunt! Boat Cleaner, and, as with that product, it’s designed to be brushed on, left for 30-60 minutes and then washed off. It left the hull in a good condition, bright white, with the worst areas requiring a second application.
