Which gelcoat cleaners are best at combating waterline yellowing on boat hulls? Ben Meakins dons his rubber gloves and puts 10 products to the test
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.
