Bio-Kleen Products Deck & Hull Cleaners

Bio-Kleen Products: Deck & Hull Cleaners Built for the Water

When a season on the water leaves your hull coated in algae, waterline scum, rust stains, and chalky oxidation, ordinary household cleaners simply won't cut it. Bio-Kleen Products has spent decades formulating high-performance, biodegradable cleaning solutions engineered specifically for the demands of the marine environment — and their deck and hull cleaners are a standout example of that commitment.

Made in the USA and proud of it. Bio-Kleen Products is a manufacturer of high-performance, biodegradable cleaning and detailing products for the marine industry, with all products manufactured and packaged in the United States, produced with ingredients from American suppliers, and operating out of their facility in Kalamazoo, Michigan. That domestic manufacturing commitment translates directly into consistent quality control that boaters have come to rely on.

The Hull Kleen & Fiberglass Cleaner Lineup

Bio-Kleen's deck and hull cleaner range centers on two proven formulas designed to handle the toughest waterborne buildup.

• Hull Kleen (Acid Hull Cleaner): An exceptionally aggressive one-step, brush-on, and spray-off acid hull cleaner that effectively removes months of algae growth, gunk, rust stains, unwanted waterlines, and chalking. It is ideal for use on aluminum boats, pontoons, marine and RV fiberglass, metals, and anodes, as it is a safer alternative to harsh acids that may damage the outer layer of the hull.
• Hull & Fiberglass Cleaner: A biodegradable, non-toxic fiberglass boat cleaner designed to dissolve and remove scum lines, algae, scale, lime, rust, corrosion, light oxidation, and most water minerals from fiberglass and acid-resistant surfaces, including fiberglass, aluminum, metals, porcelain, tile, and grout. Formulated as a clinging spray-on gel that sticks to increase surface penetration on vertical surfaces, it features a rapid action that quickly penetrates and removes buildup of all kinds.

Why Bio-Kleen Stands Apart in Eco-Friendly Marine Cleaning

Since 1987, Bio-Kleen has been an industry leader in biodegradable cleaning products made in the United States. That philosophy runs through every hull cleaner they produce. Their formulas are concentrated, allowing boaters to dilute per application to save time, money, and packaging costs — reducing environmental impact while also being 100% recyclably packaged, safe for marine and aquatic life, non-toxic, biodegradable, non-aerosol, and ozone safe.

For boaters who care about protecting the waterways they enjoy, Bio-Kleen's approach is a meaningful differentiator. Unlike aggressive solvent-based alternatives, Hull Kleen is non-aerosol and biodegradable, making cleaning as simple as it is responsible. The concentrated nature of these products also means a single bottle goes further than you might expect — an important consideration for anyone doing seasonal haul-out cleaning or professional hull maintenance.

Surfaces & Applications

Bio-Kleen deck and hull cleaners are remarkably versatile across surface types. Whether your vessel is built of gelcoat fiberglass, bare aluminum, or painted metal, these formulas are engineered to lift stains without compromising the substrate. They are ideal for marine and RV fiberglass, metals, and anodes, and are effective at removing scum lines, algae, scale, chalking, and light oxidation from both fiberglass and aluminum boat hulls.
