One Step Cleanser is a no-rinse cleaner for home brewing equipment. This non-foaming cleanser is environmentally safe, non-toxic and does not require rinsing off. When dissolved in water One Step No Rinse Cleanser releases active oxygen to form hydrogen peroxide, which is known for its disinfecting & sanitizing abilities. While One Step is considered a cleanser (not a sanitizer), it is commonly used for its sanitizing properties. After the hydrogen peroxide finishes cleaning your equipment, One Step cleaner degrades back into oxygen and water. This makes it safe for the environment and for most surfaces like brass, copper, stainless steel, aluminum, etc. One Step cleaner contains no chlorine, sulfite or phosphates. Avoid contact with eyes. How To Use One Step Cleanser on Home Brewing Equipment: Dissolve 1 Tablespoon in 1 gallon of warm water. Soak equipment in the solution for at least 1 full minute. After soaking, let equipment drip dry on clean paper towels or use right away - no rinsing required.
