10 Best Boat Cleaners 2026 in the United States

The Simple Green All-Purpose Cleaner is a versatile, concentrated cleaning spray that works on many surfaces, including floors, carpets, fabrics, and even vehicles. This makes it suitable for boat owners who need a single product to handle various cleaning tasks on their boat, from decks to upholstery. Its biodegradable formula is a plus for environmentally conscious users, as it reduces the impact on surrounding water bodies when used responsibly.

The cleaner can be used full strength for tough stains or diluted for everyday cleaning, offering good flexibility and cleaning power. It can also be applied manually or with cleaning machines like pressure washers or floor scrubbers, which helps with ease of use depending on your preferences or available equipment. One possible drawback is that, while effective on many surfaces, this is a general cleaner rather than one specialized for boat-specific issues like salt residue or marine grime.

Since it’s a spray and liquid form, care should be taken to avoid slipping on wet surfaces after use, and it’s best to follow safety instructions to ensure it’s used correctly. Simple Green presents a strong, environmentally friendly option for boat owners wanting a multi-surface cleaner that balances power with convenience, though those seeking more specialized marine cleaning might need additional products.

Simple Green Pro HD Heavy Duty Cleaner Concentrate is a versatile, professional-grade cleaner designed for tough grease and grime removal. It works well on a variety of surfaces including metal, which makes it suitable for cleaning boats, engines, and other recreational vehicles. Being biodegradable and non-corrosive, it scores well in environmental friendliness and safety for users and surfaces. It’s unscented and liquid-based, which helps with ease of use, especially when diluted as recommended.

Since it is a concentrate, you’ll need to mix it properly, which might require some care to avoid overuse or waste. While it’s not specifically marketed solely for boats, its strong degreasing ability and surface compatibility make it a solid choice for boat cleaning tasks. It’s a powerful formula meant for heavy-duty cleaning, so spot testing on delicate finishes is wise. This product balances strong cleaning power with user and surface safety, making it suitable for boat owners who need an effective multipurpose cleaner.

The Simple Green Industrial Cleaner and Degreaser is a powerful, concentrated cleaner that can tackle tough grime, grease, and stains on various washable surfaces. Its industrial strength makes it a good option for boats with heavy dirt or oily buildup, especially on hard surfaces like decks or engines. Since it’s biodegradable and recognized by the EPA’s Safer Choice Program, it presents a safer choice for the environment compared to many harsher cleaners, which is important when cleaning outdoors near water.

This cleaner can be diluted to fit the cleaning task, making it cost-effective and versatile for different tools, including pressure washers or steam extractors that some boat owners might use. While it works well on sinks, tiles, and upholstery, it is primarily designed for general industrial or home use rather than specialized marine cleaning. Users should exercise caution when applying it to painted surfaces, gel coat, or sensitive upholstery to avoid potential damage.

As a liquid concentrate, it requires proper mixing, allowing adjustment of strength based on how dirty the boat is. For those seeking a strong, biodegradable cleaner for tough messes and willing to test it first on sensitive areas, Simple Green offers a reliable and environmentally friendlier option.
