Cleaning a hull often comes down to a choice between dissolving grime and grinding it off. One product is a liquid rinse-off cleaner; the other is a set of brushes sold under boat cleaning brush accessories. Both sit in the marine maintenance cleaning repair shopping space, but they do different work. The decision depends on whether you want a chemical action or a physical scrub.

Where each product wins
The liquid cleaner wins when your goal is stain removal after waterline film, fuel, gas, exhaust, and fish-blood marks. Its description also lists rust, black streaks, lime deposits, and salt as targets and says the formula is safe for gelcoat and painted surfaces. That makes it the straightforward choice for routine cleaning.
The brush set wins when you want physical scrubbing. It includes two round blue brushes with medium-stiff bristles and a stainless steel handle, and it is described as a drill-powered cleaning brush. That makes it the better match when you want power behind the brush.
Product notes
Fiberglass Boat Hull Cleaner for Boats & Aluminum Boat Cleaner Cleaning Supplies

This is the chemical route. The listed configuration is a 32 fl oz liquid with a 946 ml item volume, and it is marked as liquid double sealed. The description suggests applying it with a sponge or sprayer, letting it sit for about two minutes, then rinsing it off, which makes it an easy addition to a routine boat wash. If you want a cleaner that does the stain-lifting step without using a brush, this fits. The item package quantity is one container. Limitation: it is a liquid, not a scrubber. Heavily caked-on surfaces will probably need a separate scrubbing tool after the rinse-off step.
Cleaning Supplies - Boat Cleaning Brush Accessories - Boat Hull Cleaner - Boa

This is the scrubbing route. The set is listed with included components of two brushes, a blue color, medium-stiff firmness, round shape, and a stainless steel handle. It is described as a drill-powered cleaning brush, so it works best if you can connect it to a drill. Reason to choose it: you get two brushes in one package, which helps if you need a spare or want to switch between surfaces. Package dimensions are given as 5.28 x 5.2 x 5.12 inches, so the storage footprint is compact. Limitation: the drill is not included, so you have to supply the power tool separately.
Final choice by use case
If your usual cleanup is about discoloration and waterline film, buy the liquid cleaner: it is intended to sit and rinse off without a scrubbing attachment. If you prefer mechanical scrubbing, choose the brush set and pair it with your own power tool. The liquid cleaner is the better match for gelcoat and painted surfaces; the brush set is the better match when you want a physical scrubbing tool.
