I found this tip at Whole New Mom. Ready? Just add white vinegar to the rinse aid compartment. Yup, that's all. So, I tried it. And it worked!! Woohoo! The glasses were so clear. We actually thought all of the dishes felt cleaner. It was just what I was looking for. BTW, I simply added white vinegar, as my indicator will tell me when I need to add more. If your dishwasher doesn't have an indicator, you can add a drop of food coloring to the vinegar so it's easier to see in the compartment.
I love this tip! And I am so happy to be able to put everything in the dishwasher again!
