Frequently Asked Questions

Product Overview

Q: What is this product?

A natural, HOCL-based cleaner and descaler formulated for marine freshwater and greywater tanks. It removes biofilm, scale, and odor-causing residue safely and effectively without harsh chemicals.​

Q: Is it certified by EPA or NSF?

Not yet. While the ingredients are widely recognized for safety and effectiveness, this product is currently marketed as a cleaning solution for tank maintenance — not as a registered disinfectant.

Q: What makes HOCL trustworthy for sanitation?

The World Health Organization (WHO) recognizes Hypochlorous Acid (HOCL) as one of the most effective and environmentally safe disinfectants available for sanitizing water and surfaces, citing its high pathogen-killing power and safety for human and environmental health.who+2

Boat Owner Concerns

Q: Will it remove slime, algae, and organic buildup?

Yes. The HOCL actively breaks down organic biofilms, slime, and microbial growth that often contaminate boat water tanks.

Q: Can it help control odors?

Yes. It eliminates odor-causing bacteria and biofilm residues, leaving tanks fresh without chlorine taste or chemical smell.

Q: Will it harm my metal or plastic tank?

No. It is non-corrosive, safe for aluminum, stainless steel, polyethylene, and fiberglass tanks, unlike bleach or strong acids.

Q: Can it cure rust or permanent corrosion?

No. It removes surface oxidation and mineral scale but cannot repair or seal corroded tank metal.

Q: Is it safe for discharge into the environment?

Yes. It is biodegradable and breaks down into water and salt, posing no harm to marine ecosystems.who+1

Cleaning and Maintenance Use

Q: How do I use it?

Mix the recommended amount with water, circulate in the tank, allow 20–30 minutes of contact time, then flush. Heavily fouled tanks may need longer dwell time.

Q: How often should I clean my water tank?

Every 2–3 months or after extended storage to prevent biofilm and mineral buildup.

Q: Should the tank be rinsed afterward?

Yes. After the cleaning cycle, flush once with fresh water before refilling.

Q: Can I clean while docked or underway?

Yes. The product is safe for use in enclosed areas and does not release toxic fumes.

Environmental & Storage Information

Q: Is it eco-friendly?

Provide an answer to the question here, with as much detail as possible to help your customers.

Q: How should it be stored?

Keep sealed in a cool, dry environment. The dry concentrate is shelf-stable for up to two years.

Technical Context and Endorsements

Q: Why does WHO recommend HOCL?

The World Health Organization and multiple expert panels have confirmed HOCL’s strong antimicrobial action, rapid disinfection capability, and superior safety profile compared to other chlorine-based agents. HOCL is effective even at low concentrations (30–100 ppm) against bacteria, viruses, and biofilm while being non-toxic and non-corrosive.who+2

Q: How is this different from bleach?

Bleach (sodium hypochlorite) is harsh and corrosive, while HOCL provides the same sanitizing power at neutral pH without damaging surfaces or equipment.who+1

Transparency and Future Development

Q: Will the product become EPA or NSF certified?

The brand intends to pursue both registrations. The formula already conforms to the same HOCL chemistry recommended by WHO and NSF for safe disinfection once registered.who+2

Q: Why should I use this instead of traditional cleaners?

Because it safely targets all main issues boat owners face — biofilm, odor, scale, and corrosion — with a formula that aligns with WHO’s preferred disinfection standard, while remaining safe for your tanks and the environment.who+2
