I've been filling the JetDri rinse reservoir with vinegar lately, and the glasses and plates are defintely clearer.
I use vinegar in the rinse aid dispenser. I just fill it up when it indicates it's empty.
Whether or not vinegar works for you depends on the type of water that you have. When it worked for me, I opened the door on the rinse cycle and tossed in about a cup of vinegar. Worked like a charm. Since I used a lot of vinegar, I didn't use the little dispenser. Now that I have a water softener, I don't need to use either a rinse agent or vinegar.
I'll have to be a dissenting vote here--I tried it a couple of years ago and it didn't do a thing for me. I had just as many spots as I did with nothing in the rinse dispenser. I hope it works for you, but don't be surprised if it doesn't.
