Pro- Con Horizon is a food service grade dish detergent. This highly effective concentrated premium hand dish detergent produces rich “grease eating” suds that quickly cut through food soils. Contains special suspending agents to keep grease and soils from redepositing on dishes, as well as lanolin to leave hands soft. This specialized surfactant blend is equally effective on a variety of other washable surfaces. Pro-Con products use a Closed Loop System and requires a Handi-Lock Connector.
