How do I use the Jet-Dry rinse agent in my dishwasher?

Fill the rinse agent dispenser until it reaches the bottom of the lip inside the opening, being careful not to overfill. Replace the cap. To check if rinse agent is needed, press the clear center of the fill cap 2 or 3 times—if rinse agent fills the center, you have enough. A full dispenser should last about one month.
