Thoroughly wash all surfaces with detergent or a compatible cleaner, followed by a water rinse before application of sanitizing solution. Prepare a solution of 1 oz. of Star San per 5 gallons of tap water. Apply on surfaces with either a cloth, mop, sponge, spray or by a 5 minute immersion. For spray application use a course mist. Spray 6 to 8 inches from surface; rub with a brush, cloth or sponge. When spraying, cover or remove all food products. For all applications, allow to air dry, however surfaces must remain wet for at least one minute.Do not rinse after Star San application.
