I use Lemon Shine even with soft water instead of Jet Dry, love it. Years ago I read a comsumers report that suggested Walmart's brand of dishwasher soap (super cheap) and Lemon Shine for hard water. I still use both today. I would also recommend not using as much soap, that may help. I do see others suggesting vinegar, my Mom used vinegar while I was growing up and that seemed to help those ugly spots. The vinegar option is probably cheaper than Lemon Shine. Good luck.
