Directions:

For every 50 parts of system add 1 part Navasol™. Fill the system with water, then allow it to stand for 15 minutes longer if encrustation is heavy. Circulate if possible and then drain. Rinse the system thoroughly with water. For coffeemaker, run an extra pot of fresh water through system before making a pot of coffee.

To remove tarnish from copper or brass, apply Navasol™ straight from the container to tarnished surface. Application can be made with sprayer, cloth, or by dipping in the solution. Within a few seconds Navasol™ will begin to remove the tarnish. After tarnish is removed, rinse brass or copper with water and then dry.

This product is NOT recommended for lacquered surfaces, hot water heaters with magnesium rods, or galvanzied surfaces. Lacquered surfaces prevent Navasol™ from reacting with the metal. Magnesium rod can cause an undesired reaction with Navasol™. Galvanized surfaces can be dissolved by Navasol™.
