Bioesque Marine Heavy Duty Bilge Cleaner Concentrate, 128 Fl Oz (Pack of 1) — Biodegradable, Marine-Safe Degreaser

Bioesque Marine Heavy Duty Bilge Cleaner Concentrate is a biodegradable, concentrated degreaser formulated to dissolve oil, grease, fuel and sludge for safer, easier bilge, engine room and deck cleaning.

This one-gallon concentrate from Bioesque is designed for boat owners and marine technicians who need a powerful, marine-safe cleaner that works in fresh or salt water. It emulsifies oils and fuels so they can be pumped out, removes black streaks and soot from surfaces, and is formulated to be non-damaging to common marine materials like fiberglass, rubber hoses, wiring, metals and plastics. Because it’s concentrated, you mix only the amount you need, reducing waste while delivering professional-strength performance.

How does Bioesque bilge cleaner remove oil and grease without harming boat parts?

The formula uses biodegradable surfactants and emulsifiers that break oil and fuel into tiny droplets so they mix with water and can be pumped away, rather than relying on harsh caustics or solvents. It’s tested to be safe on typical boat materials and won’t degrade fiberglass, rubber, wiring or metals when used as directed.

• Emulsifies oil, fuel, transmission fluid and grease for easier pumping
• Safe on fiberglass, rubber hoses, wiring, metal and plastic
• Works in both fresh and salt water environments
• Concentrated formula reduces storage and transport volume

How do I use the concentrate for best results?

Mix a measured amount of the concentrate into the bilge or a wash bucket following label instructions, run the engine briefly to circulate if applicable, then pump or bail out the emulsified water. For decks, hulls and engine rooms, apply, agitate or brush, then rinse and remove the runoff responsibly.

• Pour and dilute per label rates for bilge treatment or surface cleaning
• Run engine briefly to help circulation when treating bilges
• Pump or remove emulsified bilge water, then rinse and recheck
• Use brush or pressure rinse for stubborn grime and stains on decks

Will this cleaner help with odors and black streaks?

Yes—Bioesque’s cleaner not only disperses oils and soot but also removes the residues that trap odors and form dark streaks on hulls and decks. After treatment, bilges are left smelling cleaner and surfaces show reduced staining, making subsequent maintenance easier.

• Eliminates grime, stains, black streaks, oils and soot
• Leaves bilge and treated surfaces smelling fresher
• Effective on engine rooms, bilges, boat decks and hulls

Is this product environmentally responsible for marine use?

Bioesque Marine Heavy Duty Bilge Cleaner Concentrate is formulated with biodegradable, safer alternative ingredients to lower environmental impact compared with many solvent-based cleaners. Always follow local regulations for wastewater disposal and avoid discharging untreated bilge water directly into sensitive waters.

• Biodegradable ingredients designed as a safer alternative
• Works in both fresh and salt water to match marine needs
• Concentrated format reduces packaging and transport footprint
• Follow disposal rules—do not discharge untreated oily water into restricted areas
