Usage and Dilution Instructions

Use a minimum of 3 to 4 ounces per gallon of water for optimum protection. Solutions should be applied in final stage of parts washer by spray or soak application. Solution temperature can vary from room temperature to 180° F. Optimum protection is achieved when solution temperatures are maintained at 130°F. Solutions which are properly maintained in accordance to manufacturers’ recommendations will give a minimum of 30 days protection. Recommendations include that parts be thoroughly cleaned and free of oil and particulate, cleaning and inhibiting solutions and equipment be properly maintained, and parts are air dried before packing.
