Purple Plus BC will remove very heavy grease from heavy equipment, rolling stock and concrete. Purple Plus BC is designed to enable the user to remove most soils from the paint without brushing. Purple Plus BC can be applied at high dilutions since it is a “through the pressure washer” type degreaser. This solution works well with hot or cold water. When used in hot water it will also clean the pressure washer coils as it works. Purple Plus BC leaves no film or water spots on glass with a good rinse.
