Avance™ Hard Water Rinse Additive is designed to be dispensed with equipment installed and/or approved by your State Cleaning Solutions representative. Good product performance is dependent on many operational factors such as soil load, soil type, water temperature, wash procedures, injection nozzles and mechanical action in the machine. Your service representative will evaluate your soil load and warewashing machine to determine the correct product dosage for your system that will optimize product performance. Only a qualified service representative should set or adjust dispensing volumes. Please review label and MSDS for all product directions, precautions and first aid information.
