If you want to keep your boat in ship shape condition then you should invest in a dedicated boat cleaner product. These cleaning products are specially formulated to thoroughly clean your boat’s hull and other exposed sections, without causing any damage, and removing potentially harmful dirt and debris at the same time.

Since boat hulls are exposed to some seriously harsh elements and weather conditions, they’re always in need of a bit of TLC. Boat hulls have to endure constant contact with seawater, layers of oil and gasoline, and all manner of aquatic life that like to call a hull home. Having the right product that can cut through the grime will protect your boat and extend its lifespan.

Unfortunately, there isn’t one magic cleaning solution that will work wonders for all boats. Different hull types require different, specialist products. For example, a fiberglass hull will need a different product to a vinyl hull. And you can’t just use any old household product either.

Unlike automobiles, motorcycles, and other vehicles, boats are covered with a gel coat rather than a clear coat, and this makes them ill-suited to automotive cleaning products or anything else you might have in your cupboard.

To make sure you don’t damage your boat’s hull, we’ve compiled a list of the best boat cleaners on the market, with a useful buying guide to make sure you purchase the right boat cleaner for your needs.

Star Brite EZ-On EZ-Off Hull Cleaner

Star Brite is a popular manufacturer of marine detailing products. The brand makes all kinds of useful products, from heavy duty boat brushes to specially formulated polishes, so it shouldn’t come as a surprise to see one of their boat washes on the list. This is the EZ-On EZ-Off Hull Cleaner: a powerful solution that cuts through grime, bringing your hull back to life in no time at all.

This formula has been specially engineered to tackle the dirtiest parts of your boat: the hull, particularly the bottom of it. To do that, it uses an active hydrochloric acid to cut through the grease and grime. Since it’s made for marine applications and needs to be environmentally sound, the acid has been buffered. This allows it to deliver fast and aggressive cleaning results without harming the environment.

It’s safe to use, and perfect for cleaning more than just your hull too. Try it on your deck, in your baitwells, and inside your storage compartments.

Buying The Best Boat Cleaning Products: A Buying Guide

The cost of buying a boat is one thing, the cost of maintaining it is quite another. Keeping your boat clean is an essential task and a key part of your regular maintenance routine. There’s no escaping it. To make matters worse, boats aren’t small, and they have a lot of big areas to clean. That’s why it’s important to use the best boat cleaner products that you can, to take the edge off of an already labor-intensive task.

To make matters worse, boats are also constructed from a wide range of different materials, with each surface having different cleaning requirements to another. Your boat’s gel coat surfaces may require a different cleaning solution to the upholstery, metal areas will require different detergents to the fiberglass, et cetera, et cetera.

You’re going to need more than one type of cleaner in your arsenal, with a collection of different marine polishes and dedicated boat waxes too. No matter what type of boat you have, you’re going to need one type of base cleaner; an all ‘rounder that can cut through the bulk of the grime, across a wide range of surfaces, priming the job so that you can focus on specific areas with dedicated cleaners afterwards.

This kind of broad-match cleaner is what we’re looking at today. There are plenty available on the market, but to make sure you get the right cleaner for your boat, keep these important things in mind.

Key Features To Look Out For


Before investing in a dedicated boat cleaner, make sure that you read what surfaces it’s ideally suited for. Some of these cleaners are only suitable for hull cleaning, while others are more versatile and can be used on vinyl, glass, metal, and painted surfaces.

Naturally, the more surfaces that a cleaning solution is compatible with, the more bang you’ll get for your buck. However, increased versatility may come at the cost of a product’s strength and cleaning power.

Ask yourself whether you want a stronger, specialized product that works for a particular surface, or a more generic product that you can use all-over.


The method of application is an important feature that often gets overlooked. As we mentioned above, cleaning a boat isn’t a five minute job. It requires time and effort. Now, if you like to keep your cleaning and maintenance regime short and sweet, you may benefit from a spray cleaner. These can simply be sprayed on to a surface, and wiped away. It takes no time at all. However, the results may not be as thorough, and deep cleaning might not be possible.

Brush application, or sponge application is more time consuming, but some would argue that you get better results. Since you put more physical effort into the application, imperfections, stains, and marks are easier to remove.

Choose a boat cleaner that matches the level of effort you’re willing to spend.


Lastly, and possibly the most important thing you need to consider, is the environmental impact of any product that you use. As a boater, you have a responsibility to protect the world’s waterways. One of the best ways to keep the water clean and healthy is to use products that have environmentally-conscious ingredients. If it’s toxic, don’t use it. If it looks like it could cause harm to the water’s flora and fauna, leave it on the shelf.

Non-toxic clean agents often don’t perform as well as stronger chemicals, and there may be times when you need to use them. If you have to, make sure that you use those harsher products when your boat is out of the water. For everything else, try and use gentler cleaning agents. Always read the ingredients before you use a potentially hazard chemical on your boat. We all have a responsibility to promote clean boating, and using the right products is one of the easiest ways to fight the good fight.
