Frequently Asked Questions
What are the benefits of hypochlorous acid mouthwash?
Hypochlorous acid (HOCl) mouthwash helps eliminate germs in the mouth, including odor-causing bacteria associated with bad breath. As part of a daily oral-care routine, it can also help manage biofilm buildup, support gum health and gently cleanse irritated areas of the mouth.
Is hypochlorous acid mouthwash safe for daily use?
Yes. Hypochlorous acid mouthwash can be used as part of a daily oral-hygiene routine when properly formulated for oral use. River Refresh Hypochlorous Acid Oral Rinse is alcohol-free, fluoride-free and unflavored, with no added dyes or preservatives.
Use as directed: swish, gargle if desired and spit out. It is not intended to be swallowed.
Does hypochlorous acid mouthwash help with bad breath?
Yes. Hypochlorous acid helps eliminate odor-causing bacteria in the mouth, including bacteria associated with volatile sulfur compounds that contribute to bad breath. River Refresh Hypochlorous Acid Oral Rinse can be used after brushing and flossing, after meals or coffee, or anytime your mouth needs a fresh reset.
Can hypochlorous acid mouthwash support gum health?
Yes. Hypochlorous acid can support gum health by helping reduce bacteria and biofilm buildup along the gumline while helping soothe irritated gums and reduce inflammation. It is designed to complement brushing, flossing and professional dental care—not replace them.
Can you use hypochlorous acid mouthwash for canker sores and mouth irritation?
Yes. Hypochlorous acid can gently cleanse canker sores and other irritated areas inside the mouth, including irritation from braces, tongue piercings and lip piercings, helping keep the area clean while it heals. River Refresh Hypochlorous Acid Oral Rinse can also be used after dental procedures when discussed with your dentist.
How do you use hypochlorous acid mouthwash?
Swish ½–1 oz of River Refresh Hypochlorous Acid Oral Rinse thoroughly around the mouth, teeth and gums for 30–60 seconds, then gargle if desired and spit out. For a more complete routine, use after brushing, flossing and tongue scraping.
After rinsing, avoid eating or drinking for a few minutes to give remaining HOCl more contact time to continue eliminating germs.
Can you use hypochlorous acid in a water flosser or oral irrigator?
Yes. River Refresh Hypochlorous Acid Oral Rinse can be used with compatible water flossers and oral irrigators for targeted application along the gumline and between teeth. Add only the amount needed for each session and do not store HOCl in the device reservoir.
Is hypochlorous acid mouthwash safe for children?
River Refresh Hypochlorous Acid Oral Rinse can be used by children with adult supervision when they are able to rinse and spit properly. It is not intended to be swallowed. If you are unsure whether an oral rinse is appropriate for your child, discuss its use with your dentist or pediatric dentist.
Does hypochlorous acid mouthwash burn like alcohol-based mouthwash?
River Refresh Hypochlorous Acid Oral Rinse is alcohol-free and formulated for gentle oral use without the strong burn associated with many traditional mouthwashes. It is also unflavored and contains no added dyes or preservatives. HOCl does not rely on alcohol or strong flavors for its antimicrobial action.
What is the ppm and pH of River Refresh Hypochlorous Acid Oral Rinse?
River Refresh Hypochlorous Acid Oral Rinse is formulated at 100 ppm (0.01%) hypochlorous acid and pH 6.5–7.0. Its concentration and pH are purpose-built for oral use rather than using the same HOCl formulation across every application.

Why River Refresh
River Refresh develops fresh hypochlorous acid products for skincare, pet care, oral care and surface cleaning.
Fresh hypochlorous acid, made simple. HOCl is highly effective but sensitive to heat, light and air. Our patent-pending Activation Packet™ system lets you activate fresh HOCl when you need it—removing the uncertainty that comes with pre-mixed solutions. When you control freshness, you can trust performance.™
Custom formulation is at the core of every River Refresh product. We design concentration and pH around how each product is used rather than using one formula for every application. Our formulas use pure HOCl with no additives.
Made in Texas, USA. River—our Italian Spinone dog, company namesake and brand ambassador—inspired our search for a better way to care for pets, people and the environments we share. That idea still guides River Refresh today: effective, freshly activated HOCl made for everyday life and safe around families and pets.
