Everything you need to know about HarborShield Universal Cleaner
Traditional chemical soaps rely entirely on surfactants that lift dirt and stop working the exact moment you rinse. HarborShield Technologies utilizes advanced probiotic formulas. Our cleaners introduce active, beneficial microbes that penetrate deep into surface micro-imperfections. They digest organic residue, grease, and grime, meaning the formula continues working long after application. It cleans now, and keeps cleaning after.
Yes. Environmental stewardship is at the core of our engineering. Unlike harsh chemical cleaners that can damage aquatic ecosystems, our probiotic formulas are 100% biodegradable and designed to be safe for direct-to-water runoff. You get professional-grade performance without compromising environmental responsibility.
No. AFTER RINSE™ is a performance-driven biological cleaner, not a chemical disinfectant. It is engineered to aggressively break down the organic residue that causes recurring buildup and odors over time, rather than temporarily sanitizing a surface.
Absolutely. Both AFTER RINSE™ formulas are highly concentrated and foam cannon compatible. They generate a dense, high-cling foam that lifts visible grime immediately while allowing the active probiotics to penetrate the surface for a long-lasting clean.
Yes. AFTER RINSE™ Marine is engineered specifically for harsh marine conditions. It safely breaks down salt, fish blood, and organic exposure while remaining completely safe for gelcoat, fiberglass, non-skid decks, vinyl, and marine metals.
Yes. AFTER RINSE™ Auto is designed to be tough on road grime and bug residue, yet completely gentle on automotive finishes. It is perfectly safe for clear coats, wraps, PPF, and ceramic-coated vehicles, reducing the need for frequent deep washes.
For optimal performance and odor control, we recommend adding one scoop (per 40 gallons of tank capacity) immediately after every pump-out. The active microbes will continuously multiply, liquefying solid waste and eliminating odors between pump-outs.
Yes. Our advanced biological formula rapidly digests solid waste, sludge, and marine toilet tissue. This ensures smooth pump-outs, prevents clogs, and keeps delicate tank level sensors clean without the use of harsh, corrosive chemicals like formaldehyde.
Graywater tanks trap complex proteins, fats, and soap scum, which cause severe odors. Our Graywater Treatment introduces specialized enzymes and microbes that actively consume this specific organic buildup inside your hoses and tanks, permanently eliminating the root biological cause of the odor rather than just masking it.
Yes. The MarineBiotics™ Universal Probiotic Cleaner is a versatile, multi-surface solution. It is highly effective on vinyl seats, dashboards, fabrics, and cabin interiors. The microbes penetrate porous surfaces to digest trapped sweat, body oils, and spills, neutralizing odors on contact.
