On-Site and On-Demand

EWCO systems are compact and easy to install. Systems are designed to generate Electrolyzed Oxidizing Water on-site and on-demand from an additive made yourself with just table salt and water.

What is Electrolyzed Oxidizing Water?

Electrolyzed Oxidizing Water is electrolytically generated hypochlorous acid (HOCl), a neutral-to-acidic electrolyzed water. HOCl has been studied for over 100 years and it is an undeniable fact that it is a more powerful oxidant than chlorine bleach. Only within the last 30 years have we been able to generate solutions of near 100% HOCl in such a stable form. HOCl kills bacteria, bacterial spores, and viruses 100 times more effectively than chlorine bleach.

How does it work?

Electrolyzed Oxidizing Water is a powerful oxidant (800 to 1000 mV) that can kill microbial pathogens immediately upon contact by damaging cell walls or inactivate the pathogen by entering and disrupting proteins, lipids, and DNA.

Has it been researched?



In the last 30 years we have collected over 300 published research articles supporting the use of Electrolyzed Oxidizing Water. Nearly every common bacterial pathogen has been studied such as E. coli, Salmonella, Listeria, Vibrio, Staphylococcus, MRSA, spore forming bacteria, and many common viruses (including Norovirus) and fungi. To learn more please visit our research page and search by microbe or industry to find applicable research.

What about regulation from FDA, USDA, and EPA?

We have pages dedicated to the regulation of electrolyzed water as it pertains to the FDA, USDA, and EPA. Please visit our pages for more information. In regards to healthcare sanitation, see our page for the CDC.

Cruise Ship Sanitation

Electrolyzed Oxidizing Water is an eco-friendly and safe alternative to concentrated toxic chemicals. It can replace nearly every chemical for sanitizing staterooms, galleys, restaurants, common areas, floors, and bathrooms. EWCO Sanitizer has been demonstrated to kill over 99.9% (over 3-log reduction) of the most common microbial pathogens including Norovirus.

Combating Norovirus

Norovirus is a contstant struggle on cruise ships. Currently used chemicals are peroxide-based and are highly corrosive. Overused peroxide-based chemicals have become ineffective as Norovirus develops resistance. In addition, peroxides destroy upholstery which can be expensive to repair. Electrolyzed Oxidizing Water is not corrosive to upholstery nor does it cause discoloration. Recent research as demonstrated that Electrolyzed Oxidizing Water can inactive Norovirus on soft and hard contact surfaces with concentrations as low as 100 ppm when applied directly or by fogging.

Hand Sanitation

Hand sanitation plays an important role in preventing and controlling Norovirus outbreaks. EWCO electrolyzed water is safe and non-irritant to hands and skin and can help with hand sanitation. Electrolyzed Oxidizing Water can be placed in hand sanitation dispensers throughout the ship.


Eliminating Chemicals
Eliminating chemicals on cruise ships saves time, space, and money. Chemicals require purchasing, transporting, storing, and preparation. Storage space is limited on ships. Electrolyzed Oxidizing Water is on-site generated and requires minimal storage space. The only ingredients needed are salt, water, and electricity.

Food Safety

Not only can EWCO electrolyzed water (hypochlorous acid) kill the most common pathogens such as staphylococcus and streptococcus bacteria on contact surfaces, but it is effective against the most common foodborne pathogens such as Salmonella, Listeria, and E. coli. To learn more please visit our research page and search by microbe to find applicable research. Electrolyzed Oxidizing Water has been cleared by the FDA for no-rinse sanitation of meat, poultry, seafood, and produce if generated from EWCO systems. See FCN 1811 on the FDA website. EWCO Sanitizer is 100% safe on food. It does not cause any change in the taste or smell of food nor does it cause discoloration. Also see the letter from USDA Organic. There are no harmful residuals. Using electrolyzed water as a no-rinse sanitizer in preparation kitchens for meat, poultry, seafood, and produce can greatly reduce the incidence of foodborne illness.



Replacing toxic chemicals in the kitchen with electrolyzed water (hypochlorous acid) for sanitizing food contact surfaces will save time and add convenience. Sanitizing food preparation areas involves removing all food from the area prior to sanitation and therefore can only be done during designated hours of the day. During peak hours, when cross-contamination is at the greatest risk, no sanitizing is taking place. EWCO Sanitizer solves this problem. Being safe on food, electrolyzed water (hypochlorous acid) can be used in spray bottles to disinfect food preparation areas, cutting boards, equipment, kitchenware, and tables throughout the day without having remove or cover up food therefore controlling cross-contamination during all hours of the day.

Employee Safety

Preparation of toxic concentrated chemicals can be a safety hazard for employees as they are respiratory and skin irritants. EWCO Cleaner & Sanitizer is 100% safe for employees. It does not require any special handling. It is non-irritant and does not require gloves or masks. It can be applied directly with rags and mops or broadly by fogging and pressure spraying.

Linen Sanitation

EWCO Sanitizer can replace harsh chemicals such as quaternary ammonium (quats) used commonly to sanitize linens. Quats can cause eye irritation and contact dermatitis. For about 5% of people, quats are an extreme sensitizer and can cause a variety of asthma-like symptoms. EWCO Sanitizer is non-irritant and does not cause any respiratory or asthma-like symptoms.
